- XMM-Newton's anniversary view of nearest detected supernova
02-23-2007 · European Space Agency (ESA)
Twenty years after the first detection of SN 1987A, the nearest supernova ever detected so far, XMM-Newton provided a fresh-new view of this object. The source keeps brightening - XMM-Newton confirms.

- 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.

- 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.

- XMM-Newton reveals X-rays from gas streams around young stars
05-31-2007 · European Space Agency (ESA)
XMM-Newton has surveyed nearly two hundred stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays.

- A&A special feature: XMM-Newton deciphers the magnetic physics around forming stars
05-31-2007 · EurekAlert!
Astronomy & Astrophysics is publishing a special feature this week dedicated to the XMM-Newton extended survey of the Taurus molecular cloud. One of the main results is the identification of unusual physical processes not known before in forming stars. These unprecedented observations suggest that the gas streams falling down onto the forming star and the jets being ejected from it both play major roles in the production of X-rays.

- 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.

- 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.

- Universe contains more calcium than expected
02-06-2007 · European Space Agency (ESA)
The universe contains one and a half times more calcium than previously assumed. This conclusion was drawn by astronomers of the SRON Netherlands Institute for Space Research, after observations with ESA's XMM-Newton X-ray observatory.
