Astronomers find the most distant star clusters hidden behind a nearby cluster
01-10-2007 · EurekAlert!Astronomers have discovered the most distant population of star clusters ever seen, hidden behind one of the nearest such clusters to Earth. At a distance of more than a billion light-years, the newly discovered star clusters provide a unique probe of what similar systems in our own galaxy once looked like.

- 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.

- Hubble finds multiple stellar 'baby booms' in a globular cluster
05-02-2007 · EurekAlert!
Analysis of Hubble observations of the massive globular cluster NGC 2808 provides evidence that it has three generations of stars that formed early in the cluster's life. This is a major upset for conventional theories as astronomers have long thought that globular star clusters had a single "baby boom" of stars early in their lives and then settled down into a long, quiet middle age.

- Black hole boldly goes where no black hole has gone before
01-03-2007 · European Space Agency (ESA)
Astronomers have found a black hole where few thought they could ever exist, inside a globular star cluster. The finding has broad implications for the dynamics of stars clusters and also for the existence of a still-speculative new class of black holes called 'intermediate-mass' black holes.

- UBC astronomers discover how white dwarf stars get their 'kicks'
12-04-2007 · EurekAlert!
University of British Columbia astronomer Harvey Richer and UBC graduate student Saul Davis have discovered that white dwarf stars are born with a natal kick, explaining why these smoldering embers of sun-like stars are found on the edge rather than at the center of globular star clusters.

- Massive transiting planet with 31-hour year found around distant star
05-31-2007 · EurekAlert!
A team of astronomers with the Transatlantic Exoplanet Survey today announce the discovery of their third planet, TrES-3. It is an unusual planet because it orbits its parent star in just 31 hours.

- Largest, brightest supernova ever seen may be long-sought pair-instability supernova
05-07-2007 · EurekAlert!
UC Berkeley astronomers Nathan Smith and David Pooley report the most luminous supernova ever detected, the explosion of a super-massive star in a galaxy 250 million light years away. The scientists estimate the star was 150 times larger than our sun, and that it exploded via an entirely new mechanism never before observed. Unlike other massive supernovas, this so-called pair instability supernova left behind no black hole.

- Supernova impostor goes supernova
04-04-2007 · EurekAlert!
In a galaxy far, far away, a massive star suffered a nasty double whammy. On Oct. 20, 2004, Japanese amateur astronomer Koichi Itagaki saw the star let loose an outburst so bright that it was initially mistaken for a supernova. The star survived, but for only two years. On Oct. 11, 2006, professional and amateur astronomers witnessed the star actually blowing itself to smithereens as Supernova 2006jc.

- Supernova Radioisotopes Show Sun Was Born In Star Cluster, Scientists Say
10-05-2006 · ScienceDaily
The death of a massive nearby star billions of years ago offers evidence the sun was born in a star cluster, say astronomers at the University of Illinois at
Urbana-Champaign. Rather than being an only child, the sun could have hundreds or thousands of celestial siblings, now dispersed across the heavens.

- Largest transiting extrasolar planet found around a distant star
08-06-2007 · EurekAlert!
A team of astronomers with the Transatlantic Exoplanet Survey today announce discovery of TrES-4, a new extrasolar planet in the constellation Hercules. According to lead author Georgi Mandushev of Lowell Observatory, TrES-4 is the largest known exoplanet. It is 70 percent bigger than Jupiter with an extremely low density. The new planet, first noticed by the PSST at Lowell Observatory also has an unusual subgiant host star.

- Bonn astronomers simulate life and death in the universe
10-29-2007 · EurekAlert!
The question of how star clusters are created from interstellar gas clouds and why they then develop in different ways has now been answered by researchers at the Argelander Institute for Astronomy at the University of Bonn with the aid of computer simulations. The scientists have solved -- at least at a theoretical level -- one of the oldest astronomical puzzles, namely the question of whether star clusters differ in their internal structure.
