NASA’s Earth Observing-1 satellite shows toxic sludge from the Ajkai Timföldgyar alumina (aluminum oxide) plant in western Hungary


 Toxic Sludge in Hungary

On Oct. 4, 2010, an accident occurred at the Ajkai Timföldgyar alumina (aluminum oxide) plant in western Hungary, when a corner wall of a waste-retaining pond broke, releasing a torrent of toxic red sludge down a local stream. Several nearby towns were inundated, including Kolontar and Devecser, where the sludge was up to 6.5 feet deep in places. Four people were killed immediately, several more were missing and dozens of residents were hospitalized for chemical burns.

On Oct. 9, 2010, the Advanced Land Imager on NASA’s Earth Observing-1 satellite captured this natural-color image of the area.

This could be the last time. Shuttle Discovery


Shuttle Discovery’s Last Launch

THIS COULD BE THE LAST TIME

Space shuttle Discovery is the oldest in NASA’s fleet, but will be the first to retire after one final spaceflight. NASA pulled out all the stops Sept. 20, 2010, when Discovery made its last trip to the launch pad for its final flight. The shuttle is due to launch Nov. 1, 2010.

Discovery made its way toward Launch Pad 39A on Sept. 20, 2010 during its final rollout ahead of a Nov. 1 launch. Blazing white xenon lights lit the path for the towering shuttle and its Apollo-era crawler transporter. The move took hours to cover less than 4 miles.

By the end of its career, space shuttle Discovery will have flown 39 space missions since its first flight in 1984. Over that time, countless dedicated engineers and technicians serviced the spacecraft.

James Cameron Shares NASA’s Exploration of Earth in ‘Avatar’ Videos


James Cameron Shares NASA’s Exploration of Earth in ‘Avatar’ Videos
08.24.10

See at http://www.nasa.gov/topics/earth/features/avatar.html

James Cameron, director of “Avatar,” the most successful film ever released, is featured in a series of new NASA public service announcements that describe the many contributions of the agency’s Earth science program to environmental awareness and exploration of our home planet.

“When NASA ventures into space, it remembers to keep a steady eye on home,” Cameron said. “Its fleet of Earth-orbiting satellites constantly reveals our whole planet: its remotest places, its mysteries and the powerful influence of humans.”

Cameron’s 3-D epic, based on the fictional planet of Pandora is coming back to theaters this week. The story centers on a beautiful planet threatened by forces that want to exploit its natural resources.

The public service announcements feature “Avatar” film imagery and include computer animations and data from NASA’s fleet of Earth-observing satellites. NASA has 14 science satellites in orbit making cutting

GALACTIC VOLCANO. M87 galaxy.


Massive Attack Massive Attack

This image shows the eruption of a galactic “super-volcano” in the massive galaxy M87, as witnessed by NASA’s Chandra X-ray Observatory and NSF’s Very Large Array (VLA). At a distance of about 50 million light years, M87 is relatively close to Earth and lies at the center of the Virgo cluster, which contains thousands of galaxies.
The cluster surrounding M87 is filled with hot gas glowing in X-ray light (and shown in blue) that is detected by Chandra. As this gas cools, it can fall toward the galaxy’s center where it should continue to cool even faster and form new stars.

However, radio observations with the VLA (red) suggest that in M87 jets of very energetic particles produced by the black hole interrupt this process. These jets lift up the relatively cool gas near the center of the galaxy and produce shock waves in the galaxy’s atmosphere because of their supersonic speed. The interaction of this cosmic “eruption” with the galaxy’s environment is very similar to that of the Eyjafjallajokull volcano in Iceland that occurred in 2010. With Eyjafjallajokull, pockets of hot gas blasted through the surface of the lava, generating shock waves that can be seen passing through the grey smoke of the volcano. This hot gas then rises up in the atmosphere, dragging the dark ash with it. This process can be seen in a movie of the Eyjafjallajokull volcano where the shock waves propagating in the smoke are followed by the rise of dark ash clouds into the atmosphere.

In the analogy with Eyjafjallajokull, the energetic particles produced in the vicinity of the black hole rise through the X-ray emitting atmosphere of the cluster, lifting up the coolest gas near the center of M87 in their wake. This is similar to the hot volcanic gases drag up the clouds of dark ash. And just like the volcano here on Earth, shock waves can be seen when the black hole pumps energetic particles into the cluster gas.

Into the Night

Researchers do not yet know what is lighting up IRAS 05437+2502, a small, faint nebula that spans only 1/18th of a full moon toward the constellation of the Taurus. Particularly enigmatic is the bright upside-down V that defines the upper edge of this floating mountain of interstellar dust.

This ghost-like nebula involves aIRAS 05437+2502 small star-forming region filled with dark dust that was first noted in images taken by the IRAS satellite in infrared light in 1983. This recently released image from the Hubble Space Telescope shows many new details, but has not uncovered a clear cause of the bright sharp arc.
