Mystery Solved: High-Energy Fireworks Linked to Massive Star Cluster |
| General Information |
What is an American Astronomical Society Meeting release? A major news announcement issued at an American Astronomical Society meeting, the premier astronomy conference. Call it the Bermuda Triangle of our Milky Way Galaxy: a tiny patch of sky that has been known for years to be the source of the mysterious blasts of X-rays and gamma rays. Now, a team of astronomers, led by Don Figer of the Space Telescope Science Institute in Baltimore, Md., has solved the mystery by identifying one of the most massive star clusters in the galaxy. The little-known cluster, which has not been catalogued, is about 20 times more massive than typical star clusters in our galaxy, and appears to be the source of the powerful outbursts. Supporting evidence for the hefty weight of this cluster is the presence of 14 red supergiants, hefty stars that have reached the end of their lives. They bloat up to about 100 times their normal size before exploding as supernovae. This image shows the star-studded region surrounding the massive star cluster. The bluish cluster is inside the white box. A close-up of the cluster can be seen in the inset photo. Read more: * The Full Story [ http://hubblesite.org/newscenter/archive/releases/2006/03/full/ ] |

Floods in Portugal

Floods in Portugal |
| Description |
Heavy rains left central Portugal in a state of emergency on October 25, 2006, said news reports. The rains triggered mudslides and floods throughout Portugal and western Spain, but the worst of the damage was near Lisbon, the country's capital, and the areas immediately to its north. By the time the clouds cleared on October 27, the tributaries of the Tejo (Tagus) River were still swollen with the run-off. Tainted blue with mud in the top image, the flooded rivers extend both east and west from the Tejo. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the image on October 27 using both visible and infrared light. In this type of image, water stands out from the surrounding land because of its black color. Sediment in the water, often a sign of recent flooding, can give it a blue color. In the lower image, taken two weeks earlier, the Tejo is black like the Atlantic Ocean to its west, and its tributaries are not visible. Near the lower edge of both images, Lisbon and surrounding cities color the land cement gray. Plant-covered land is bright green, while lightly vegetated land is tan. Patches of freshly burned land along the right side of the lower image are red. In the space of two weeks, the rainfall has clearly spurred plant growth. The landscape has turned green in the top image with the flush of new vegetation. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel. The MODIS Rapid Response Team provides daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Europe_3_01 ] of Portugal in a variety of resolutions.

Heat Wave in Western Europe
| Title |
Heat Wave in Western Europe |
| Description |
Western Europe continued to bake in late July 2006. Following an unusually warm spell between July 12 and 19, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13743 ] temperatures across most of the region remained much warmer than normal. This image shows land surface (as opposed to air) temperatures collected from July 20-27, 2006, compared to the average temperatures for that period over the past six years (2000-2005). Places that were up to ten degrees Celsius warmer than average are deep red, while places that were up to ten degrees cooler than average are deep blue. Places where the temperatures were average are white. The temperatures were measured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite. In the center of the image, deep red areas of very warm temperatures spread across Germany, as well as France (to the west), and Poland (to the east). To the north (top center), both Norway (west) and Sweden (east) were much warmer than average. Only small pockets of the region were cooler than average: northeastern Spain, the "toe" of Italy's boot and the western half of the island of Sicily, and parts of Greece (lower right). July 2006 was a record-breaking month for heat in many Western European countries, coming in as the hottest July on record in several countries, including Belgium, Denmark, Ireland, the Netherlands, and the United Kingdom.

Fires in Spain and Portugal

Fires in Spain and Portugal |
| Description |
According to news reports, hot [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13743 ] and dry conditions settling in across the Iberian Peninsula brought devastating wildfires to Spain and Portugal in early August 2006. This image of the area was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Terra [ http://terra.nasa.gov ] satellite on August 7, 2006. Places where MODIS detected actively burning fires are outlined in red. Smoke spills out over the Atlantic Ocean. The high-resolution image provided above has a spatial resolution of 250 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.

Fires in Spain and Portugal

Fires in Spain and Portugal |
| Description |
In northwestern Spain and Portugal, numerous fires raced across dry forestland at the beginning of the third week of August 2006. When the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite passed over head on August 13, the sensor detected more than a dozen active fires (outlined in red) on the Atlantic Coast of the Iberian Peninsula. The photo-like image on the left is paired with a shortwave- and near-infrared-enhanced image on the right. In the false-color image, burned areas stand out as deep red marks compared to the bright green of unburned vegetation. Areas of sparse vegetation, such as cities or arid locations, appear in shades of pinkish-tan to gray. Within some of the fire perimeter outlines, a bright pink glow is visible. This bright glow often indicates open flame at the time of the satellite overpass. The high-resolution image provided above has a spatial resolution of 250 meters per pixel. The MODIS Rapid Response System provides twice-daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Spain ] of the entire Iberian Peninsula in additional resolutions and formats.
