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.

- Rethinking last century's closest, brightest supernova
01-09-2007 · EurekAlert!
February 2007 marks the 20th anniversary of the nearest and brightest supernova humans have seen in 400 years. Called SN1987A, it burned for weeks in the Large Magellanic Cloud, and provided astronomers with new information that forced them to rethink theories of how massive stars explode. Now UC Berkeley astronomer Nathan Smith says that theory needs rethinking again. Exploding stars like SN1987A may have been luminous blue variables, not blue supergiants.

- NASA's Chandra sees brightest supernova ever
05-07-2007 · EurekAlert!
The brightest stellar explosion ever recorded may be a long-sought new type of supernova, according to observations by NASA's Chandra X-ray Observatory and ground-based optical telescopes. This discovery indicates that violent explosions of extremely massive stars were relatively common in the early universe, and that a similar explosion may be ready to go off in our own Galaxy.

- Hubble photographs grand spiral galaxy Messier 81
05-29-2007 · EurekAlert!
The sharpest image ever taken of the large "grand design" spiral galaxy Messier 81 is being released today. The image, constructed from a series of images taken with NASA/ESA Hubble Space Telescope, is among the largest ever released. Messier 81 is one of the brightest galaxies that can be seen from the Earth.

- Astronomers See Inside A Quasar For The First Time
10-06-2006 · ScienceDaily
For the first time, astronomers have looked inside quasars -- the brightest objects in the universe -- and have seen evidence of black holes. The study lends further confirmation to what scientists have long suspected -- that quasars are made up of super-massive black holes and the super-heated disks of material that are spiraling into them.

- Hubble finds strong contender for galaxy distance record
02-12-2008 · EurekAlert!
The NASA/ESA Hubble Space Telescope, with a boost from a natural "zoom lens," has found the strongest evidence so far for a galaxy with a redshift significantly above 7. It is likely to be one of the youngest and brightest galaxies ever seen right after the cosmic "dark ages," just 700 million years after the beginning of our universe (redshift ~7.6).

- Hubble finds double Einstein ring
01-10-2008 · EurekAlert!
The NASA/ESA Hubble Space Telescope has revealed a never-before-seen optical alignment in space: a pair of glowing rings, one nestled inside the other like a bull's-eye pattern. The double-ring pattern is caused by the complex bending of light from two distant galaxies strung directly behind a foreground massive galaxy, like three beads on a string.

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.

11-14-2006 · EurekAlert!
Frenzied star-making in the Milky Way Galaxy starting about 2,400 million years ago had extraordinary effects on life on Earth. Harvests of bacteria in the sea soared and crashed in a succession of booms and busts, with an instability not seen before or since.
