Ashes to Ashes, Dust to Dust

March 30th, 2010

This new composite image from NASA’s Chandra X-ray Observatory and Spitzer Space Telescope shows the dusty remains of a collapsed star, the dust from which is flying past and engulfing a nearby family of stars. Scientists believe the stars in the image are part of a stellar cluster in which a supernova exploded. Material ejected in the explosion now blows past these stars at high velocities. In this image of G54.1+0.3, X-ray data from Chandra are shown in blue, and data from Spitzer in green (a shorter wavelength) and red-yellow (a longer one). The white source near the center of the image is a dense, rapidly rotating neutron star, or pulsar, all that remains of a core-collapse supernova explosion. The pulsar generates a wind of high-energy particles — seen in the Chandra data — that expands into the surrounding environment, illuminating the material ejected in the supernova explosion. The unique environment into which this supernova exploded makes it possible for astronomers to observe the condensed dust from the supernova that is usually too cold to emit in the infrared.

Preparing Discovery for Flight

March 26th, 2010

A specialized transporter brought the payload canister to Launch Pad 39A in preparation for the STS-131 mission. The canister, which is the same dimensions as the shuttle’s cargo bay, held the Leonardo supply module during the move from processing to the shuttle. Leonardo will be packed inside space shuttle Discovery for launch. In this image, the payload canister holding the Leonardo supply module is hoisted to the clean room at Launch pad 39A.
