 Filled with trash and discarded items, the unpiloted ISS Progress 38
supply vehicle departed from the International Space Station at 7:22
a.m. (EDT) on Aug. 31, 2010. Russian flight controllers conduct
thruster tests with the Progress to gather engineering data until it
deorbited and
burned up in Earth's atmosphere over the Pacific Ocean. Its departure
cleared the way for the arrival of the next Russian resupply vehicle,
ISS Progress 39, which launched Sept. 8 and will dock Sept. 10,
delivering 2.5 tons of food, fuel and supplies for the Expedition 24
crew. Image Credit: NASA

This composite image shows the Rosette star formation region, located
about 5,000 light years from Earth. Data from the Chandra X-ray
Observatory are colored red and outlined by a white line. The X-rays
reveal hundreds of young stars in the central cluster and fainter
clusters on either side. Optical data from the Digitized Sky Survey and
the Kitt Peak National Observatory (purple, orange, green and blue)
show large areas of gas and dust, including giant pillars that remain
behind after ... Continue reading...

 The Fourmile Canyon Fire continued to burn west of Boulder, Colo., in
this image taken on Sept. 7, 2010, casting a long line of smoke to the
east that was visible from NASA's Aqua satellite in its orbit around
the Earth. MODIS, the Moderate Resolution Imaging Spectroradiometer, on
NASA’s Aqua satellite captured this natural-color image of the fire at
2:40 p.m. local time (20:40 UTC) on Sept. 7. The red outline
corresponds with the unusually high surface temperatures associated
with an activ... Continue reading...

 Two extremely bright stars illuminate a greenish mist in this image
from the Spitzer Space Telescope's "GLIMPSE360" survey. This mist is
comprised of hydrogen and carbon compounds called polycyclic aromatic
hydrocarbons (PAHs), which also are found here on Earth in sooty
vehicle
exhaust and on charred grills. In space, PAHs form in the dark clouds
that give rise to stars. These molecules provide astronomers a way to
visualize the peripheries of gas clouds and study their structures in
great d... Continue reading...

 On August 1, 2010, almost the entire Earth-facing side of the sun
erupted in a tumult of activity. This image from the Solar Dynamics
Observatory of the news-making solar event on August 1 shows the
C3-class solar flare (white area on upper left), a solar tsunami
(wave-like structure, upper right), multiple filaments of magnetism
lifting off the stellar surface, large-scale shaking of the solar
corona, radio bursts, a coronal mass ejection and more. This
multi-wavelength extreme ultraviolet s... Continue reading...

A beautiful new image of two colliding galaxies has been released by
NASA's Great Observatories. The Antennae galaxies, located about 62
million light years from Earth, are shown in this composite image from
the Chandra X-ray Observatory (blue), the Hubble Space Telescope
(gold), and the Spitzer Space Telescope (red).
The collision, which began more than 100 million years ago
and is still occurring, has triggered the formation of millions of
stars in clouds of dusts and gas in the galaxie... Continue reading...

 The north polar layered deposits are layers of dusty ice up to 2 miles
thick and approximately 620 miles in diameter. We can see the layers
exposed on the walls of troughs and scarps cut into the deposits, such
as the trough wall imaged here. The bright region at the top is the
flat surface above the trough wall; it is higher than the terrain
underneath. The wall exposing these layers has a vertical relief of
about 1970 feet. It is thought that the north polar layered deposits
likely formed r... Continue reading...

 In the Vehicle Assembly Building at NASA's Kennedy Space Center in
Florida, workers prepare External Tank-138, hanging vertically in the
transfer aisle, for its lift onto a test cell where it will be checked
out before launch. ET-138, the last newly manufactured tank, is
designated to fly on space shuttle Endeavour's STS-134 mission to the
International Space Station. Launch is targeted for Feb. 26, 2011.

 Hundreds of fires burned across western Russia on August 2, 2010,
but it is the smoke that conveys the magnitude of the disaster in this
true-color image from the Moderate Resolution Imaging Spectroradiometer
(MODIS) on NASA’s Terra satellite. Dense gray-brown smoke extends
across the width of this image, a distance of about 1,700 kilometers
(1,000 miles). The smoke clearly continues both east and west beyond
the edge of the image, and is visible in both previous and successive
orbits of th... Continue reading...
