Massive black hole smashes record

10-30-2007 · EurekAlert!

Using two NASA satellites, astronomers have discovered the heftiest known black hole to orbit a star. The new black hole, with a mass 24 to 33 times that of our Sun, is more massive than scientists expected for a black hole that formed from a dying star.

Unusual supernovae may reveal intermediate-mass black holes in globular clusters
01-29-2008 · EurekAlert!
A strange and violent fate awaits a white dwarf star that wanders too close to a moderately massive black hole. According to a new study, the black hole's gravitational pull on the white dwarf would cause tidal forces sufficient to disrupt the stellar remnant and reignite nuclear burning in it, giving rise to a supernova explosion with an unusual appearance.

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.

New type of massive stellar death
12-20-2006 · EurekAlert!
So far we have thought that the signature of the death of a massive star was an energetic explosion called a "supernova." New observations show that this is not always the case. On the contrary, a team led by Danish researchers has now discovered that some massive stars die by collapsing into a black hole returning very little material into the interstellar medium. The new discovery is published in Nature.

New X-ray source in nearby galaxy spawns mystery
01-09-2008 · EurekAlert!
Astronomers studying a nearby galaxy have spied a rare type of star system -- one that contains a black hole that suddenly began glowing brightly with X-rays. Though this type of star system is supposed to be rare, it's the second such system discovered in that galaxy, called Centaurus A. The discovery suggests that astronomers have more to learn about the lives and deaths of massive stars in galaxies such as our own.

Heaviest stellar black hole discovered in nearby galaxy
10-17-2007 · EurekAlert!
Astronomers have located an exceptionally massive black hole in orbit around a huge companion star. By combining data from NASA's Chandra X-ray Observatory and the Gemini telescope on Mauna Kea, Hawaii, M33 X-7 was determined to be the most massive stellar black hole known. This result has intriguing implications for the evolution and ultimate fate of massive stars.

Biggest 'small' black hole discovered
10-19-2007 · EurekAlert!
Discovery of the largest example of a 'small' black hole -- one formed from the collapse of a single massive star at the end of its lifetime -- has led scientists to reevaluate of how black holes come into being, according to a report in Nature.

Galaxy survey focuses on 'pre-teen' years
03-05-2007 · EurekAlert!
A massive project to generate an all-color map of the galaxies in a small area of sky is yielding new information about the universe's "pre-teen" years and the early evolution of galaxies and galaxy clusters. The UC Berkeley-led AEGIS survey has already generated 19 papers set for publication this spring, reporting a binary black hole at the core of one galaxy, new lensing galaxies, and information about our universe as it matured through early adolescence.

Hyperfast star proven to be alien
01-28-2008 · EurekAlert!
A young star is speeding away from the Milky Way so fast that astronomers have been puzzled by where it came from; based on its young age it has traveled too far to have come from our galaxy. The researchers have determined that it came from our neighboring galaxy, the Large Magellanic Cloud. The result suggests that it was ejected from that galaxy by a yet-to-be-observed massive black hole.
