- X-ray evidence supports possible new class of supernova
01-04-2007 · EurekAlert!
Evidence for a significant new class of supernova has been found with NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton. These results strengthen the case for a population of stars that evolve rapidly and are destroyed by thermonuclear explosions. Such "prompt" supernovas could be valuable tools for probing the early history of the cosmos.

- 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.

- Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
04-24-2007 · EurekAlert!
One of the largest panoramic images ever taken with Hubble's cameras has been released to celebrate the 17th anniversary of the launch and deployment of the NASA/ESA Hubble Space Telescope. The image shows a 50 light-year-wide view of the tumultuous central region of the Carina Nebula where a maelstrom of star birth -- and death -- is taking place.

- 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.

- A star's death comes to light
01-09-2007 · EurekAlert!
Using NASA's Chandra X-ray Observatory, scientists have created a stunning new image of one of the youngest supernova remnants in the galaxy. This new view of the debris of an exploded star helps astronomers solve a long-standing mystery, with implications for understanding how a star's life can end catastrophically and for gauging the expansion of the universe.

- Possible progenitor of special supernova type detected
02-13-2008 · EurekAlert!
Using data from NASA's Chandra X-ray Observatory, scientists have reported the possible detection of a binary star system that was later destroyed in a supernova explosion. The new method they used provides great future promise for finding the detailed origin of these important cosmic events.
