| Title |
Burn Scars in the Pacific Northwest |
| Description |
Fire season is winding down in western North America, but this false-color image from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite reveals the season?s fire-scarred landscape. Vegetation is in shades of green, while burned areas are red. Scars dot the Northern Rockies from Canada (roughly top half of image) to Montana (bottom right) and Idaho, to its west. Additional large scars are visible in the Coast Mountains (left) which stretch from British Columbia, Canada, southward into Washington. Clouds are white and light blue, lakes and rivers are dark blue, and snow is bright blue. Naturally bare ground (or extremely low vegetation), such as on the highest mountains ridges at top center, or in the Columbia River Basin (bottom center), is pinkish tan. MODIS captured this image on October 4, 2003. Image courtesy Jesse Allen, based on data from the MODIS Rapid Response Team at NASA GSFC |

Fires in Northern Washington |
| Description |
In the mountains of northern Washington, the Tripod Complex Fire burned from July into August. This image of the region was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite on August 6, 2006. Places where MODIS detected actively burning fires are marked in red. The actively burning parts of the Tripod Complex make two rough circles in the rugged terrain northeast of the city of Twisp. Smoke billows thickly across the state and into British Columbia, Canada. According to the August 7 report from the National Interagency Fire Center, [ http://www.nifc.gov/information.html ] the Tripod Complex Fire had grown to an estimated 57, 535 acres, and firefighters had it about 10 percent contained. Numerous residences and other structures were threatened by the fire, which was burning through timber that had been killed by beetle infestation. The high-resolution image provided above has a spatial resolution of 250 meters per pixel.

Three Sisters Volcanoes
| Title |
Three Sisters Volcanoes |
| Description |
The ground near one of the long-dormant Three Sisters volcanoes in the Cascade Mountains of west-central Oregon has risen approximately 10 centimeters in a 10-by-20-km parcel since 1996, meaning that magma or underground lava is slowly flowing into the area, according to a research team from the U.S. Geological Survey. The Three Sisters area?which contains five volcanoes?is only about 170 miles from Mount St. Helens, which erupted in 1980. Both are part of the Cascades Range, a line of 27 volcanoes stretching from British Columbia in Canada to northern California. This perspective view was created by draping a simulated natural color ASTER image over digital topography from the U.S. Geological Survey National Elevation Dataset.

| Title |
Manicouagan Impact Crater on Earth |
| Explanation |
The Manicouagan Crater [ http://www.linkdirectory.com/airphoto/1030.html ] in northern Canada [ http://www.odci.gov/cia/publications/factbook/geos/ca.html ] is one of the oldest impact craters [ http://observe.ivv.nasa.gov/nasa/exhibits/craters/impact_home.html ] known. Formed during a surely tremendous impact [ http://antwrp.gsfc.nasa.gov/apod/ap990711.html ] about 200 million years ago, the present day terrain supports a 70-kilometer diameter hydroelectric reservoir [ http://www.ilec.or.jp/database/nam/nam-26.html ] in the telltale form of an annular lake [ http://epod.usra.edu/archive/epodviewer.php3?oid=40640 ]. The crater itself has been worn away by the passing of glaciers [ http://www.glacier.rice.edu/land/5_whatisaglacier.html ] and other erosional processes. Still, the hard rock [ http://duke.usask.ca/~reeves/prog/geoe118/geoe118.011.html ] at the impact site has preserved much of the complex impact structure [ http://antwrp.gsfc.nasa.gov/apod/ap960120.html ] and so allows scientists a leading case to help understand large impact features on Earth [ http://www.lpi.usra.edu/publications/slidesets/impacts.html ] and other [ http://antwrp.gsfc.nasa.gov/apod/ap001213.html ap960906.html ] Solar System bodies. Also visible above [ http://earth.jsc.nasa.gov/lores.cgi?PHOTO=STS009-48-3139 ] is the vertical fin of the Space Shuttle [ http://antwrp.gsfc.nasa.gov/apod/ap990411.html ] Columbia from which the picture was taken in 1983. |

Kalamalka Lake Eclipse
| Title |
Kalamalka Lake Eclipse |
| Explanation |
Recorded on August 28th [ http://www.spaceweather.com/eclipses/ gallery_28aug07_page2.htm ], this serene total lunar eclipse sequence looks southwest down Kalamalka Lake toward the lights of Coldstream [ http://maps.google.com/maps?q=Coldstream,+BC,+Canada&ie=UTF8 &ll=50.225355,-119.268951&spn=0.240294,0.320663&t=h&z=11&om=1 ], British Columbia. An exposure every 4 minutes captured the Moon's position and eclipse phase, until the Moon set behind the town lights and a hill on the horizon. In fact, the sequence effectively measures the duration of the total phase of the eclipse [ http://www.mreclipse.com/Special/LEprimer.html ]. Around 270 BC, the Greek astronomer Aristarchus [ http://www-groups.dcs.st-and.ac.uk/~history/ Mathematicians/Aristarchus.html ] also measured the duration of lunar eclipses - though probably without the benefit of digital clocks [ http://itotd.com/articles/297/ revenge-of-the-analog-clock/ ] and cameras. Still, using geometry, he devised [ http://www.phy6.org/stargaze/Shipprc2.htm ] a simple and impressively accurate way to calculate the Moon's distance, in terms of the radius of planet Earth, from the eclipse duration. |

A Leonids Star Field
| Title |
A Leonids Star Field |
| Explanation |
As meteor after meteor streaked across a moonless sky, photographers [ http://leonids.hq.nasa.gov/leonids/gallery/date/all.html ] across the world snapped pictures [ http://SpaceWeather.com/meteors/gallery_18nov01.html ] of the 2001 Leonids Meteor Shower [ http://comets.amsmeteors.org/meteors/showers/leonidhistory.html ]. Many recognized this as the best meteor shower they had ever seen. In fact, the 2001 Leonids [ http://science.nasa.gov/headlines/y2001/ast15nov_1.htm ] was the most active meteor [ http://www.nineplanets.org/meteorites.html ] shower since the mid-1960s. The above photo captures three Leonid meteors [ http://antwrp.gsfc.nasa.gov/apod/ap011104.html ] crossing a photogenic star-field [ http://antwrp.gsfc.nasa.gov/apod/ap000929.html ]. On the far right is the Pleiades [ http://antwrp.gsfc.nasa.gov/apod/ap010506.html ] star cluster [ http://antwrp.gsfc.nasa.gov/apod/open_clusters.html ]. The brightest meteor [ http://antwrp.gsfc.nasa.gov/apod/ap011119.html ] crosses right in front of the Hyades star cluster [ http://www.aspsky.org/mercury/mercury/9803/hyades.html ], situated below the image center. Just left of center is the bright planet Saturn [ http://antwrp.gsfc.nasa.gov/apod/saturn.html ], and the bright star below Saturn is Aldebaran [ http://www.astro.uiuc.edu/~kaler/sow/aldebaran.html ]. The ten-minute exposure was taken near Victoria [ http://www.city.victoria.bc.ca/ ], British Columbia [ http://www.gov.bc.ca/ ], Canada [ http://www.cia.gov/cia/publications/factbook/geos/ca.html ] at 2:45 am PST [ http://atm.geo.nsf.gov/ieis/time.html ] on 2001 November 18. |

Launch of the Sun Pillar
| Title |
Launch of the Sun Pillar |
| Explanation |
On January 16, NASA's space shuttle Columbia roared [ http://antwrp.gsfc.nasa.gov/apod/ap011115.html ] into blue morning skies above Kennedy Space Center on STS-107 [ http://spaceflight.nasa.gov/shuttle/ ], the first shuttle mission of 2003. But this is not a picture of that launch [ http://spaceflight.nasa.gov/gallery/images/shuttle/sts-107/ html/03pd0113.html ]! It was taken on the morning of January 16 though, at sunrise, looking eastward toward Lake Ontario from just outside of Caledon, Ontario, Canada. In the picture a sun pillar [ http://ww2010.atmos.uiuc.edu/(Gh)/ guides/mtr/opt/ice/sp.rxml ], sunlight reflecting from ice crystals [ http://www.sundog.clara.co.uk/halo/pillar.htm ] gently falling through the cold air, seems to shoot above the fiery Sun still low [ http://antwrp.gsfc.nasa.gov/apod/ap020902.html ] on the horizon. By chance, fog [ http://antwrp.gsfc.nasa.gov/apod/ap021122.html ] and clouds forming over the relatively warm lake look like billowing smoke from a rocket's exhaust plume [ http://antwrp.gsfc.nasa.gov/apod/ap020308.html ] and complete the launch illusion. Amateur photographer Lauri Kangas stopped on his way to work to record the eye-catching [ http://www.photon-echoes.com ] sun pillar launch. |

| Explanation |
Vega is a bright blue star 25 light years away. Vega [ http://stardate.utexas.edu/radio/StarDateDB.FM$RETRIEVE?value=06/15/1996&field=ScriptAirDate&html=Test+Request+Date ] is the brightest star in the Summer Triangle [ http://eagle.online.discovery.com/DCO/doc/1012/world/starshack/starshack080796/starshack.html ], a group of stars easily visible summer evenings in the northern hemisphere. The name Vega [ http://www.astro.wisc.edu/~dolan/constellations/hr/7001.html ] derives from Arabic origins, and means "stone eagle." 4,000 years ago, however, Vega [ http://stardate.utexas.edu/radio/StarDateDB.FM$RETRIEVE?value=05/20/1995&field=ScriptAirDate&html=Test+Request+Date ] was known by some as "Ma'at" - one example of ancient human astronomical knowledge and language. 14,000 years ago, Vega [ http://stardate.utexas.edu/radio/StarDateDB.FM$RETRIEVE?value=07/10/1994&field=ScriptAirDate&html=Test+Request+Date ], not Polaris [ http://www.arcorp.com/polaris.html ], was the north star [ http://antwrp.gsfc.nasa.gov/apod/ap961201.html ]. Vega [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?1995ApJ%2E%2E%2E450%2E%2E364G&db_key=AST&nosetcookie=1 ] is the fifth brightest star in the night sky, and has a diameter almost three times that of our Sun. Life [ http://www.seti-inst.edu/phoenix/contact.html ] bearing planets, rich in liquid water, could possibly exist around Vega [ http://lsnt7.lightspeed.net/~astronomy/lifezones/lifezones.html ]. The above picture [ http://www.jpl.nasa.gov/comet/moffatt1.html ], taken in January, finds Vega, the Summer Triangle [ http://antwrp.gsfc.nasa.gov/apod/ap961212.html ], and Comet Hale-Bopp [ http://antwrp.gsfc.nasa.gov/apod/ap970610.html ] high above Victoria [ http://www.city.victoria.bc.ca/ ], British Columbia [ http://www.gov.bc.ca/ ], Canada. |

Natural Color Mosaic of North America |
| Original Caption Released with Image |
This natural-color image combines cloud-free data from over 500 Multi-angle Imaging SpectroRadiometer (MISR) orbits with shaded relief Digital Terrain Elevation models from the Shuttle Radar Topography Mission (SRTM) and other sources. An astonishing diversity of geological features, ecological systems and human landscapes across North America is indicated within the image, which spans from 56N, 136W at the upper left to 16N 48W at lower right. In addition to the contiguous United States, the scene spans from British Columbia in the northwest to Newfoundland in the northeast, and extends eastward to the lonely Bermuda Islands and southward to the Bahamas, Cuba and Mexico. Draped in green, the eastern and central United States and Canada contrast with the vibrant geology that is laid bare across the arid portions of the southwestern United States and central Mexico. Along Mexico's east coast, the lush vegetation to the east of the Sierra Madre mountain range indicates the orographic rainfall gradient along this subtropical-tropical coast. In the high Rocky Mountains and in British Columbia's Coast Range, many peaks remain snow-covered year-round. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously and every 9 days views the entire globe between 82 north and 82 south latitude. This data product was generated from a portion of the imagery acquired during years 2000 - 2004. The image is displayed in an Albers Conic Equal Area projection with the projection center at 36 North, 92 West. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. |

This natural-color image from the Multi-angle Imaging SpectroRadiometer (MISR) captures the beauty of the western United States and Canada. Data from 45 swaths from MISR's vertical-viewing (nadir) camera were combined to create this cloud-free mosaic. The image extends from 48° N 128° W in the northwest, to 32°N, 104° W in the southeast, and has been draped over a shaded relief Digital Terrain Elevation Model from the United States Geological Survey. The image area includes much of British Columbia, Alberta and Saskatchewan in the north, and extends southward to California, Arizona and New Mexico. The snow-capped Rocky Mountains are a prominent feature extending through British Columbia, Montana, Wyoming, Colorado and New Mexico. Many major rivers originate in the Columbia Plateau region of Washington, Oregon and Idaho. The Colorado Plateau region is characterized by the vibrant red-colored rocks of the Painted Desert in Utah and Arizona, and in New Mexico, White Sands National Park is the large white feature in the Southeast corner of the image with the Malpais lava flow just to its North. The southwest is dominated by the Mojave Desert of California and Nevada, California's San Joaquin Valley, the Los Angeles basin and the Pacific Ocean. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously from pole to pole, and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This data product was generated from a portion of the imagery acquired during 2000-2002. The panels utilize data from blocks 45 to 65 within World Reference System-2 paths 31 to 53. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology. |

Cascade Mtns. Oregon |
| Original Caption Released with Image |
The ground near one of the long-dormant Three Sisters volcanoes in the Cascade Mountains of west-central Oregon has risen approximately 10centimeters in a 10-by-20-km parcel since 1996, meaning that magma or underground lava is slowly flowing into the area, according to a research team from the U.S. Geological Survey. The Three Sisters area -- which contains five volcanoes -- is only about 170 miles from Mount St. Helens, which erupted in 1980. Both are part of the Cascades Range, a line of 27volcanoes stretching from British Columbia in Canada to northern California. This perspective view was created by draping a simulated natural color ASTER image over digital topography from the U.S. Geological Survey National Elevation Dataset. This image was acquired on May 28, 2000 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched December 18,1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. Science team leader, Bjorn Eng of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The Terra mission is part of NASA's Earth Science Enterprise, along-term research and technology program designed to examine Earth's land, oceans, atmosphere, ice and life as a total integrated system. The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology, and measuring surface heat balance. Size: 20 x 25 km (12 x 15 miles) Location: 44.1 deg. North lat., 122.1 deg. West long. Orientation: View towards Southeast Image Data: ASTER bands 1,2, and 3.
