===================================

**TW Hydrae and HD 98800A:
Chandra Adds to Story of the Way We Were
- Data from NASA's Chandra X-ray Observatory have enabled astronomers
to use a new way to determine if a young star is surrounded by a
planet-forming disk like our early Sun. These results suggest that disks
around young stars can evolve rapidly to form planets, or they can be
disrupted by close encounters with other stars.

**SNR 0103-72.6:
Chandra Finds Rich Oxygen Supply Inside Glowing Ring
- Scientists using NASA's Chandra X-ray Observatory have detected large
amounts of oxygen and other elements in the remnant of a star that
exploded in a nearby galaxy. For years scientists have known that the
elements necessary for life are created in massive stars and dispersed
in supernova explosions, but the process has rarely been caught "on camera."
