A star's death comes to light

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.

1. Intergalactic 'shot in the dark' shocks astronomers
   12-18-2007 · EurekAlert!
   A team of astronomers has discovered a cosmic explosion that seems to have come from the middle of nowhere -- thousands of light-years from the nearest galaxy-sized collection of stars, gas, and dust. This "shot in the dark" is surprising because the type of explosion, a long-duration gamma-ray burst, is thought to be powered by the death of a massive star.

2. Giant planets do not come as lonely hearts
   02-14-2008 · EurekAlert!
   Scaled versions of Jupiter and Saturn orbiting a star 5000 light-years away, half as massive as the sun, have been revealed from an effort involving a world-wide net of telescopes, including the UK's Liverpool Telescope on the Canary Islands. This marks the first discovery of another system of planets that has striking similarities with our solar system.

   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.

7. In limiting life span, study finds booming bacteria innocent
   08-07-2007 · EurekAlert!
   Aging flies are simply crawling with bacteria -- both inside and out -- but their microbial infestations don't seem to hasten the insects toward death, according to a new study in the Aug. issue of the journal Cell Metabolism, a publication of Cell Press. The findings suggest that the energy the flies expend to fight their burgeoning bugs, comes without a longevity trade-off, the researchers said.

   11-13-2007 · EurekAlert!
   Cranberry sauce is not the star of the traditional Thanksgiving Day meal, but when it comes to health benefits, the lowly condiment takes center stage. In fact, researchers at Worcester Polytechnic Institute have found that compounds in cranberries are able to alter E. coli bacteria, which are responsible for a host of human illnesses, in ways that render them unable to initiate an infection.

9. 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.

10. A newly discovered solar system contains scaled-down versions of Saturn and Jupiter
    02-14-2008 · EurekAlert!
    A team of international astronomers reports in the Feb. 15 issue of Science the discovery of a solar system nearly 5,000 light years away with scaled-down versions of Jupiter and Saturn. Their findings suggest our galaxy could conceivably contain many star systems similar to our own. NSF sponsored the research.
