Hubble Sees Stars and a Stripe in Celestial Fireworks |
|
A delicate ribbon of gas floats eerily in our galaxy. A contrail from an alien spaceship? A jet from a black-hole? Actually this image, taken by NASA's Hubble Space Telescope, is a very thin section of a supernova remnant caused by a stellar explosion that occurred more than 1,000 years ago. |

IAU Symposium 258: The Ages of Stars
How old is that star? That is one of the most difficult questions to answer in galactic astrophysics. Stellar ages
lie at the heart of astrophysics, and stellar evolution is all about time and how stars change with time. Stellar
and galactic evolution cannot be understood without some knowledge of ages. Now is an appropriate time to examine
the problem of stellar ages in detail. IAU Symposium 258 will bring together astronomers from the around the world to discuss
the current state of the problem of estimating ages of individual stars and of populations, where the advances are now being made,
and what the near future offers. Read more...
Hubble Servicing Mission 4
Hubble precisely measured the age of the universe. It found evidence of dark energy. It brought you images of distant
galaxies in the young universe. And now, with the state-of-the-art instruments delivered by Servicing Mission 4 (SM4),
the Hubble Space Telescope will look onto the universe with new eyes, surpassing even its previous vision. Hubble was
designed to be repaired and upgraded by astronauts, and these servicing missions have occurred several times since
Hubble’s launch in 1990. NASA has selected a crew for the upcoming servicing, and the astronauts have begun
training. Read more...
Hubble Legacy Archive
We are pleased to announce that the Hubble Legacy Archive (HLA) has entered
the Data Release 1 (DR1) phase of operation. The HLA is an augmentation of
the Hubble Space Telescope data archive service. The goal of the archive is to
optimize the science derived from the telescope by providing improved browsing
capabilities and easy access to both standard and enhanced Hubble data
products. The Hubble Legacy Archive currently contains data from the ACS, WFPC2,
NICMOS, STIS, FOS, and GHRS instruments. The HLA project is a collaboration
between the Space Telescope Science Institute, the Space Telescope European
Coordinating Facility, and the Canadian Astronomy Data Centre.
