Star on a Hubble diet
12-11-2006 · EurekAlert!High-resolution observations from Hubble have shed light on the real mass of a star previously believed to be amongst the heaviest known in our Milky Way. Originally, the mass of the star was thought to be an incredible 200-300 solar masses, but turned out to be only 100 solar masses.

- Colliding galaxies make love, not war
10-17-2006 · EurekAlert!
A new Hubble image of the Antennae galaxies is the sharpest yet of this merging pair of galaxies. As the two galaxies smash together, billions of stars are born, mostly in groups and clusters of stars. The brightest and most compact of these are called super star clusters.

- Hubble yields direct proof of stellar sorting in a globular cluster
10-24-2006 · EurekAlert!
A seven-year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass. Heavier stars slow down and sink to the cluster's core, while lighter stars pick up speed and move across the cluster to its periphery. This process, called "mass segregation," has long been suspected for globular star clusters, but has never before been directly seen in action.

06-20-2007 · EurekAlert!
A new composite image of the Eta Carinae from NASA's Chandra X-ray Observatory and Hubble Space Telescope shows the remnants of a massive eruption from the star during the 1840s. Eta Carinae is a mysterious, extremely bright and unstable star located a mere stone's throw -- astronomically speaking -- from Earth at a distance of only about 7500 light years. The star is thought to be consuming its nuclear fuel at an incredible rate, while quickly drawing closer to its ultimate explosive demise.
