Iceland Glacier Recession 1997 to 2000 |
| Abstract |
This animation is a close up zoom into largest area of glacier recesion at the Breidamerkurjokull glacier in Iceland. The data from 1997 is taken from Landsat 5 and the 2000 data is from Landsat 7. The Breidamerkurjokull glacier in Iceland has been measured by Landsat to be receding since 1973. In 1997, Landsat 5 took several other images of the glacier. It was thought by some glacierologists that this particular glacier was receding quicker in the late 1990s than it did in the late 1980s or 1970s. After careful analysis Goddard's Glacierologist, Dorothy Hall, concluded that the recession from 1997 to 2000 occurs at a similar rate to the recession between 1973 and 2000. It is extremely controversial whether or not this recession is caused by global warming. |

Bright Waters Around Iceland
| Title |
Bright Waters Around Iceland |
| Description |
On the first day of summer in the Northern Hemisphere, the clouds around Iceland cleared to reveal a bright aquamarine ocean. The water is probably colored by coccolithophores, single-celled plants that are coated in a white calcium carbonate. The tiny plants can form massive blooms, visible in satellite imagery such as this image, acquired by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS [ http://seawifs.gsfc.nasa.gov/SEAWIFS.html ]) on the Orbview-2 satellite on June 21, 2004. A cruise northwest of Ireland reported a bloom of Emiliana huxleyi northwest of Ireland a week before this image was taken, and it's likely that the bloom seen here is the same species. Emiliana huxleyi is the most abundant species of coccolithophores. Although not as bright as the water immediately off the Iceland coast, relatively bright water can be seen in an irregular band that stretches out of the image to the southwest of the island for over a thousand kilometers.

Chilly Temperatures During t

| Title |
Chilly Temperatures During the Maunder Minimum |
| Description |
Many things can change temperatures on Earth: a volcano erupts, swathing the Earth with bright haze that blocks sunlight, and temperatures drop, greenhouse gases trap heat in the atmosphere, and temperatures climb. From 1650 to 1710, temperatures across much of the Northern Hemisphere plunged when the Sun entered a quiet phase now called the Maunder Minimum. During this period, very few sunspots appeared on the surface of the Sun, and the overall brightness of the Sun decreased slightly. Already in the midst of a colder-than-average period called the Little Ice Age, Europe and North America went into a deep freeze: alpine glaciers extended over valley farmland, sea ice crept south from the Arctic, and the famous canals in the Netherlands froze regularly—an event that is rare today. The impact of the solar minimum is clear in this image, which shows the temperature difference between 1680, a year at the center of the Maunder Minimum, and 1780, a year of normal solar activity, as calculated by a general circulation model. Deep blue across eastern and central North America and northern Eurasia illustrates where the drop in temperature was the greatest. Nearly all other land areas were also cooler in 1680, as indicated by the varying shades of blue. The few regions that appear to have been warmer in 1680 are Alaska and the eastern Pacific Ocean (left), the North Atlantic Ocean south of Greenland (left of center), and north of Iceland (top center). If energy from the Sun decreased only slightly, why did temperatures drop so severely in the Northern Hemisphere? Climate scientist Drew Shindell and colleagues at the NASA Goddard Institute for Space Studies tackled that question by combining temperature records gleaned from tree rings, ice cores, corals, and the few measurements recorded in the historical record, with an advanced computer model of the Earth's climate. The group first calculated the amount of energy coming from the Sun during the Maunder Minimum and entered the information into a general circulation model. The model is a mathematical representation of the way various Earth systems—ocean surface temperatures, different layers of the atmosphere, energy reflected and absorbed from land, and so forth—interact to produce the climate. When the model started with the decreased solar energy and returned temperatures that matched the paleoclimate record, Shindell and his colleagues knew that the model was showing how the Maunder Minimum could have caused the extreme drop in temperatures. The model showed that the drop in temperature was related to ozone [ http://earthobservatory.nasa.gov/Library/Ozone/ozone_2.html ], in the stratosphere, the layer of the atmosphere that is between 10 and 50 kilometers from the Earth's surface. Ozone is created when high-energy ultraviolet light from the Sun interacts with oxygen. During the Maunder Minimum, the Sun emitted less strong ultraviolet light, and so less ozone formed. The decrease in ozone affected planetary waves, the giant wiggles in the jet stream that we are used to seeing on television weather reports. The change to the planetary waves kicked the North Atlantic Oscillation (NAO) [ http://earthobservatory.nasa.gov/Study/NAO_200307/NAO.html ]—the balance between a permanent low-pressure system near Greenland and a permanent high-pressure system to its south—into a negative phase. When the NAO is negative, both pressure systems are relatively weak. Under these conditions, winter storms crossing the Atlantic generally head eastward toward Europe, which experiences a more severe winter. (When the NAO is positive, winter storms track farther north, making winters in Europe milder.) The model results, shown above, illustrate that the NAO was more negative on average during the Maunder Minimum, and Europe remained unusually cold. These results matched the paleoclimate record. By creating a model that could reproduce temperatures recorded in paleoclimate records, Shindell and colleagues reached a better understanding of how changes in the stratosphere influence weather patterns. With such an understanding, scientists are better poised to understand what factors could influence Earth's climate in the future.

Grassfire in Iceland
| Title |
Grassfire in Iceland |
| Description |
In western Iceland in late March 2006, a large fire broke out in the grasses of a wetland area, which had been dried out by a period of persistent north winds. According to local reports, some farmers in the area had to evacuate their livestock to protect them from the fast-moving, wind-driven blaze. In this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite on March 30, 2006, a long plume of smoke blows westward away from the fire, whose location is marked in red in the image.

Grassfire in Iceland
| Title |
Grassfire in Iceland |
| Description |
At the end of March 2006, a grassfire broke out in western Iceland, perhaps as a result of a smoldering cigarette butt. Although this area near the coast to the northwest of the country's capital, Reykjavik, is typically very wet, a period of persistent north winds dried out the grass and made it flammable. The fire burned for several days, threatening farms and livestock and resulting in Iceland's largest fire in its recorded history. This image from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite was captured on April 6, 2006. The burned area appears as a large brownish-charcoal splotch in the center of the image. The fire started inland and burned all the way to the coast. This is a false-color image, and unburned vegetation appears red, clouds appear white, and the Atlantic Ocean (image left) appears nearly black. Several partially ice-covered lakes are scattered across the burned landscape, these lakes appear light blue.

Grimsvotn Volcano Erupts
| Title |
Grimsvotn Volcano Erupts |
| Description |
Iceland?s Grimsvotn Volcano began erupting on November 2, 2004, forcing officials to divert air traffic from the region to prevent ash from damaging aircraft engines. The volcano sits beneath the Vatnajokull Ice Cap, Europe?s largest glacier, and is Iceland?s most frequently active volcano. This eruption may be connected to the draining of a glacier lake in the volcano?s caldera. Buried under a 200-meter thick ice shelf, the lake is under extreme pressure. Melting water fills the lake, and when levels are high enough, the water lifts the ice dam, draining the lake. Grimsvotn Lake drained in mid-October, lifting some of the pressure from the volcano. The flood was followed by a series of earthquakes, and on November 2, an eruption. As of November 3, the eruption was still occurring, and ash was reported to have drifted as far northeast as Finland. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA?s Terra [ http://terra.nasa.gov/ ] satellite captured this view of the erupting volcano. The plume is largely made of steam rising from the melting ice above the volcano, but ash is mixed in as well. Against the white of the Vatnajokull Ice Cap, the white eruption plume is difficult to see in the true color image. The false color image, which shows ice as bright red, provides the contrast needed to see the steam plume. As the plume is blown north, the steam dissipates, and the dark ash is more visible. The shadow on the snow along the top edge of the image may be ash on the glacier. As the eruption continues, flooding is likely around the volcano. So far, some of the glacier-fed rivers southeast of the volcano have flooded, and more floods are expected. The high-resolution images provided above are at MODIS? maximum resolution of 250 meters per pixel. The MODIS Rapid Response Team provides both the true [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004307-1102/Iceland.A2004307.1210 ] and false [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2004307-1102/Iceland.A2004307.1210.367 ] color images in additional resolutions.

Dust Plumes off Iceland |
| Description |
Plumes of dust blew off the southern coast of Iceland in late June 2007. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image on June 23, 2007. The dust appears as grayish blurs emanating from the coast southward over the North Atlantic Ocean. Blue-green algal blooms also fringe the coastline. Iceland's winter of 2006-2007 brought relatively light snow, leaving the local vegetation little shelter from frost. Both the vegetation and soil dried further in two weeks of arid weather prior to this dust storm. Strong winds from the north added the final ingredient needed for dust plumes in late June.

Landslide Buries Valley of t

Landslide Buries Valley of the Geysers |
| Description |
Geysers are a rare natural phenomena found only in a few places, such as New Zealand, Iceland, the United States (Yellowstone National Park), and on Russia's far eastern Kamchatka Peninsula. On June 3, 2007, one of these rare geyser fields was severely damaged when a landslide rolled through Russia's Valley of the Geysers. The landslide—a mix of mud, melting snow, trees, and boulders—tore a scar on the land and buried a number of geysers, thermal pools, and waterfalls in the valley. It also blocked the Geyser River, causing a new thermal lake to pool upstream. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER [ http://asterweb.jpl.nasa.gov/ ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this infrared-enhanced image on June 11, 2007, a week after the slide. The image shows the valley, the landslide, and the new thermal lake. Even in mid-June, just days from the start of summer, the landscape is generally covered in snow, though the geologically heated valley is relatively snow free. The tree-covered hills are red (the color of vegetation in this false-color treatment), providing a strong contrast to the aquamarine water and the gray-brown slide. According to the Russian News and Information Agency (RIA [ http://en.rian.ru/ ]) [English language], the slide left a path roughly a kilometer and a half (one mile) long and 200 meters (600 feet) wide. Within hours of the landslide, the water in the new lake inundated a number of additional geysers. The geysers directly buried under the landslide now lie under as much as 60 meters (180 feet) of material, according to RIA reports. It is unlikely that the geysers will be able to force a new opening through this thick layer, adds RIA. Among those directly buried is Pervenets (Firstborn), the first geyser found in the valley, in 1941. Other geysers, such as the Bolshoi (Greater) and Maly (Lesser) Geysers, were silenced when buried by water building up behind the new natural dam. According to Vladimir and Andrei Leonov of the Russian Federation Institute of Volcanology and Seismology, [ http://www.kscnet.ru/ivs/expeditions/2007/Geyser_Valley-06-2007/Geyser_Valley-06.htm ], the new lake appears to be stable and draining gradually through the earthen dam, alleviating fears of a catastrophic flood. Should the new lake drain enough, many of the inundated geysers may restart. Initial reports from the Volcanology and Seismology Institute state this has already happened for some geysers. Geysers outside of the slide region, including the Velikan (Giant) Geyser and a major section of the geyser field known as Vitrazh (Stained Glass) appear to have escaped damage. In addition to destroying a number of geysers, the landslide may have damaged habitats in the Valley of the Geysers. The thermal waters and heated steam jets made this valley warmer than the surrounding landscape, and the warmth supported a unique ecosystem. The loss of a large part of its heat source may alter the ecosystem, but it is not clear what additional longer-term changes might occur. For example, salmon that spawn in the Geyser River will be confined to the lower reaches of the river, and bears, which depended on salmon, will need to shift feeding grounds correspondingly.

Low Pressure System off Iceland |
| Description |
The MODIS instrument onboard NASA's Terra satellite captured this true-color image of a large low pressure system off the coast of Iceland. In the Northern Hemisphere, the circulation around low pressure systems is counterclockwise and inward, a result of the Coriolis Force. Air flowing inward in low pressure systems has no where to go but up. The rising air cools, and if it rises far enough, clouds and precipitation can form.

Extratropical Cyclones near Iceland |
| Description |
A cyclone is a low-pressure area of winds that spiral inwards. Although tropical storms most often come to mind, these spiraling storms can also form at mid- and high latitudes. Two such cyclones formed in tandem in November 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Terra [ http://terra.nasa.gov/ ] satellite took this picture on November 20. This image shows the cyclones south of Iceland. Scotland appears in the lower right. The larger and perhaps stronger cyclone appears in the east, close to Scotland.Cyclones [ http://en.wikipedia.org/wiki/Cyclone ] at high and mid-latitudes are actually fairly common, and they drive much of the Earth's weather. In the Northern Hemisphere, cyclones move in a counter-clockwise direction, and both of the spiraling storms in this image curl upwards toward the northeast then the west. The eastern storm is fed by thick clouds from the north that swoop down toward the storm in a giant "V" shape on either side of Iceland. Skies over Iceland are relatively clear, allowing some of the island to show through. South of the storms, more diffuse cloud cover swirls toward the southeast.

| Title |
New Measurements of Arctic Ozone |
| Description |
The winter of 2004-2005 saw the second highest chemical ozone destruction ever observed over the Arctic. Polar ozone is destoyed when chlorine, cold temperatures, and sunlight mix in the atmosphere 8-50 kilometers above the Earth's surface. Since ozone shields the Earth from ultraviolet light, the high-energy light that causes sunburns and is associated with skin cancers, low ozone levels could threaten human health. Ultraviolet levels remained near normal through the winter, however, because unusual weather conditions brought ozone from the Earth's ozone-rich mid-latitudes to the pole to fill in the gaps left by the extreme ozone depletion. These images show the fluctuations in ozone during the Arctic winter of 2005. The top two images show the average total column ozone over the Arctic during the months of January and March, 2005, and the lower image shows total column ozone on a single day, March 11, 2005. The images are based on data collected by the Ozone Monitoring Instrument [ http://www.knmi.nl/omi/publ-en/news/index.html ] (OMI) aboard NASA's Aura [ http://aura.gsfc.nasa.gov/ ] satellite. During this time period, the Microwave Limb Sounder, another instrument on the Aura satellite, measured 50 percent ozone loss, the second-highest level ever observed behind the 60 percent loss measured in 1999-2000. Despite this, the lowest total column ozone values in polar regions are slightly higher in March than in January, on average, as evidenced by the broad splashes of red that represent high ozone levels. Stratospheric winds carried the ozone north into the Arctic, compensating for the significant chemical loss, so that no blue or purple holes representing low ozone levels appear in the March image. Black circles over the North pole show where OMI did not collect data. On a single day, March 11, 2005, ozone was distributed far more unevenly, with dark red, almost black areas of high ozone over the Aleutian Islands, Asia, and Europe, and a pale blue thin spot over Iceland and Greenland. This reveals that even though ozone values appeared to be near normal on average throughout March, some regions experienced much lower ozone levels—and therefore, a greater exposure to UV light—on an individual day. For more information and images, see "NASA Spacecraft Measures Unusual 2005 Arctic Ozone Conditions" [ http://www.nasa.gov/vision/earth/lookingatearth/aura-060205.html ] on the NASA portal.

North Atlantic Bloom
| Title |
North Atlantic Bloom |
| Description |
Reminiscent of the distinctive swirls in a Van Gogh painting, millions of microscopic plants color the waters of the North Atlantic with strokes of blue, turquoise, green, and brown. Fed by nutrients that have built up during the winter and the long, sunlit days of late spring and early summer, the cool waters of the North Atlantic come alive every year with a vivid display of color. The microscopic plants, called phytoplankton, that give the water this color are the base of the marine food chain. Some species of phytoplankton are coated with scales of calcium (chalk), which turn the water electric blue. Chlorophyll and other light-capturing pigments in others give the water a deep green hue. The proliferation of many different species in various stages of growth and decay provides many nuances of color in this concentrated bloom. The bloom stretches across hundreds of kilometers, well beyond the edges of this photo-like image, captured on June 23, 2007, by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) flying aboard NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. The upper left edge of the image is bounded by Greenland. Iceland is in the upper right. Plumes of dust [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14345 ] are blowing off the island, probably adding nutrients to the surface waters to its south.

The intense blue and green colors of the ocean water in this photo-like image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite on July 15, 2007, are made by millions of surface-dwelling ocean plants. Called phytoplankton, the plants are the base of the marine food chain. The brilliant color shown here may only be a part of the full bloom. Stocked with nutrients that have built up during the winter and bathed in the long, sunlit days of late spring and early summer, the cool waters of the North Atlantic come alive every year with a vivid display of color that can stretch over thousands of kilometers. You can download a 250-meter-resolution KMZ file of the North Atlantic bloom [ http://earthobservatory.nasa.gov/NaturalHazards/Archive/Jul2007/iceland_amo_2007196.kmz ] suitable for use with Google Earth.

Smoke Over Northern Europe and the Atlantic |
| Description |
Milky white over the deep blue Norwegian Sea, a thick cloud of smoke drifts north along the coast of Norway in this photo-like image, taken on May 7, 2006, by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. The smoke is coming from hundreds of fires [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13539 ] burning in western Russia, most of which are probably agricultural fires. By the time this image was taken, smoke had lingered over the Norwegian Sea for more than a week as the fires continued to burn. In this image, hazy skies extend from Denmark, lower right, west to Iceland, upper left. The densest of the smoke hangs over the Shetland Islands (right) and the Faroe Islands (left). The northern shores of Great Britain are in the lower left corner of the image. The large image provided above has a resolution of 250 meters per pixel.

Smoke Over Northern Europe and the Atlantic |
| Description |
Although skies may have been mostly cloud-free over Ireland and the United Kingdom on May 10, 2006, a pall of haze dimmed the day. The white haze drifts from the Atlantic Ocean northwest of Ireland, over the island country, and southeast over the Celtic Sea and the English Channel in this photo-like image taken by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. The smoke is coming from hundreds of fires [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13539 ] burning in western Russia, most of which are probably agricultural fires. The fires have been burning since late April, and in that time, the smoke has drifted northwest over Scandinavia, the Norwegian Sea, Iceland, and the Atlantic Ocean before curving south to blanket Ireland. Unrelated to the smoke, the ocean southwest of Ireland is brilliant green-blue where a large phytoplankton bloom is growing. Phytoplankton are microscopic plants that grow in the sun-lit surface waters of the ocean. When large colonies develop, the blooms are visible from space by the bright color they lend the normally dark water. The large image provided above has a resolution of 250 meters per pixel. The image is available in additional resolutions [ http://rapidfire.sci.gsfc.nasa.gov/subsets/subsets.php?Europe.2006130.aqua.2km ] from the MODIS Rapid Response Team.

Flooding in Iceland
| Title |
Flooding in Iceland |
| Description |
Most spring floods are triggered by rain or melting snow, but when the Skafta River of southern Iceland flooded in late April 2006, geologic activity may have been the driver. The river flows out from under the Vatnajokull Ice Cap, a large permanent field of snow and ice that covers more than 8,000 square kilometers of southeastern Iceland, including a number of volcanoes and other regions of geothermal activity. Over these hotspots, the lower layer of the ice cap melts to form glacier lakes, some of which drain into the Atlantic Ocean through rivers such as the Skafta. Other lakes are dammed by walls of ice from the overlying glacier. Catastrophic floods can occur when water breaks through the ice dams and bursts into the rivers, or when geologic activity increases and melts more water. On April 22, 2006, floods swamped the Skafta River. The flood water was accompanied by dangerously high levels of sulfur, possibly from increased geologic activity, prompting the Civil Protection Department to issue a warning, said local news reports. In flood, the fast-moving river swept over the dark, volcanic soil west of the ice cap, and carried it into the ocean. The ocean was milky green with sediment when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image on April 27.

Vatnajökull, Iceland
| Title |
Vatnajökull, Iceland |
| Description |
In southeastern Iceland lies the largest glacier in all of Europe: Vatnajökull. In places 400 meters (1,312 feet) thick, the massive glacier covers 8 percent of the entire country. Capping several active volcanoes, Vatnajökull is subject to glacial melt floods when volcanic heat melts portions of the bottom side of the glacier. The water eventually rises above the level of the caldera and spills downward under the pull of gravity. The stillness of this Landsat image belies such destructive potential. The glacier appears light blue where it is swept clean of snow, but white where covered (top of image). The southern reaches of the great glacier inch southward from Skaftafell National Park and out toward the Atlantic Coast. The glacial tongues that drain the glacier are light blue, and are scalloped by grayish moraines, which are deposits of glacial till (rock debris ground up and carried along by the glacier). Scrubby vegetation over hard, volcanic rock is red. This image was acquired by Landsat 7's Enhanced Thematic Mapper plus (ETM+) sensor on August 4, 1999. This is a false-color composite image made using shortwave infrared, green, and blue wavelengths. The image has also been sharpened using the sensor's panchromatic band.

Aurora Over Clouds
| Title |
Aurora Over Clouds |
| Explanation |
Aurorae usually occur high above the clouds. The auroral glow [ http://www.geo.mtu.edu/weather/aurora/ ] is created when fast-moving particles ejected [ http://antwrp.gsfc.nasa.gov/apod/ap000309.html ] from the Sun [ http://www.nineplanets.org/sol.html ] impact air molecules high in the Earth's atmosphere [ http://csep10.phys.utk.edu/astr161/lect/earth/atmosphere.html ]. An oxygen molecule [ http://pearl1.lanl.gov/periodic/elements/8.html ], for example, will glow in a green light when reacquiring an electron [ http://www.aip.org/history/electron/ ] lost during a collision with a solar particle. The lowest part of an aurora [ http://www.rog.nmm.ac.uk/leaflets/aurora/aurora.html ] will typically occur at 100 kilometers up, while most clouds [ http://www.cloudyskies.net/clouds.html ] usually exist only below about 10 kilometers. The relative heights of clouds and aurorae are shown clearly in the above picture [ http://www.iww.is/art/shs/pages/page22.html ] from Iceland [ http://www.cia.gov/cia/publications/factbook/geos/ic.html ], where aurorae are relatively common. Over the past weekend, one of the largest sunspot groups [ http://www.sunspot.noao.edu/INFO/INTRODUCTION/sunspot-mar272001.html ] ever recorded has been associated with explosive solar activity [ http://antwrp.gsfc.nasa.gov/apod/ap000403.html ] and expansive terrestrial aurora displays [ http://apod.gsfc.nasa.gov/cgi-bin/apod/apod_search?aurora+AND+Earth ]. Although in Earth's northern hemisphere aurorae [ http://www.pfrr.alaska.edu/~pfrr/AURORA/INDEX.HTM ] are usually seen only in the far north, these aurorae [ http://www.spaceweather.com ] were so prevalent they were imaged by a continuous nighttime camera [ http://concam.net/kp/about.html ] operating in southern Arizona [ http://www.state.az.us/ ]! |

Volcano and Aurora in Iceland |
| Explanation |
Sometimes both heaven "and" Earth erupt. In Iceland [ http://www.cia.gov/cia/publications/factbook/geos/ic.html ] in 1991, the volcano Hekla [ http://www.south.is/hekla.html ] erupted at the same time that auroras [ http://www.exploratorium.edu/learning_studio/auroras/ ] were visible [ http://www.iww.is/art/shs/ ] overhead. Hekla [ http://www.norvol.hi.is/hekla.html ], one of the most famous volcanoes [ http://www.crystalinks.com/volcanoesactive.html ] in the world, has erupted [ http://www.volcanolive.com/faq.html ] at least 20 times over the past millennium, sometimes causing great destruction [ http://www.each-mara.net/volcano/santorini.pdf ]. The last eruption [ http://www.norvol.hi.is/heklaeruption.html ] occurred only two years ago but caused only minor damage. The green auroral band [ http://antwrp.gsfc.nasa.gov/apod/ap010402.html ] occurred fortuitously [ http://www.nationalgeographic.com/ngm/100best/wallpaper09.html ] about 100 kilometers above the erupting lava [ http://volcano.und.nodak.edu/vwdocs/frequent_questions/group1_new.html ]. Is Earth [ http://volcano.und.nodak.edu/vw.html ] the Solar System's only planet with both auroras [ http://www.physicsweb.org/article/news/5/1/10 ] and volcanos [ http://www.thursdaysclassroom.com/index_07oct99.html ]? |

Ring of Fire Revisited
| Title |
Ring of Fire Revisited |
| Explanation |
Early on Saturday [ http://skyandtelescope.com/observing/objects/eclipses/ article_924_1.asp ], May 31 (UT) the new Moon will once again slide across the Sun's fiery disk, and once again [ http://antwrp.gsfc.nasa.gov/apod/ap020610.html ] an annular solar eclipse [ http://sunearth.gsfc.nasa.gov/eclipse/ASE2003/ ASE2003.html ] will be the result -- since the Moon's apparent diameter [ http://www.rc-astro.com/composite/sun_moon.htm ] will be a little too small to completely cover the Sun [ http://www.earthview.com/tutorial/tutorial.htm ]. But this time celestial geometry [ http://members.aol.com/atsinclair/ecl2003.htm ] has conspired to produce a broad D-shaped region [ http://sunearth.gsfc.nasa.gov/eclipse/ASE2003/ASE2003gif/ ASE2003-1b.GIF ] for viewing the annular phase that extends into the far northern hemisphere, rather than creating a thin track racing across land and sea. The characteristic ring of fire will be visible from northern Scotland, Iceland, and parts of Greenland. Otherwise a partial eclipse will be more widely visible as across Europe, along with parts of Asia and North America, the Moon will appear to take a "bite" out of the Sun. While the northerly observers might certainly expect a dramatic view [ http://www.astrosurf.com/alphaweb/10mai94/ ], it will probably not look quite like this one [ http://www.skyscapes.com/Shadows%20in%20the%20Sky/ RingFire.htm ], recorded with a foreground of palm trees during a 1992 annular eclipse.
