How Will The Universe End? Like This.

enus Unlike Earth, Venus lacks a magnetic field to deflect powerful solar outbursts -- as can be seen in this NASA-created image, a still from the video "Dynamic Earth: Exploring Earth's Climate Engine."

V838 Monocerotis is a red variable star in the constellation Monoceros about 20,000 light years from the Sun, and possibly one of the largest known stars. The previously unknown star was observed in early 2002 experiencing a major outburst. Originally believed to be a typical nova eruption, it was then realized to be something completely different. The reason for the outburst is still uncertain, but several conjectures have been put forward, including an eruption related to stellar death…

Astronomers have been able to observe a star's snow line - the point where the water vapour surrounding a stellar body becomes snow and ice - for the first time ever. Usually, that boundary is so close to a star that astronomers aren't able to see it, but a sudden burst of brightness pushed the snow line in this young solar system far enough that it could be detected on Earth. It could help to understand more about how planets form.

Astronomers Watch Delayed Broadcast of a Powerful Stellar Eruption (02/15/2012) - The observations of Eta Carinae's light echo are providing new insight into the behavior of powerful massive stars on the brink of detonation. The views of the nearby erupting star reveal some unexpected results, which will force astronomers to modify physical models of the outburst.

Preview of a Forthcoming Supernova At the turn of the 19th century, the binary star system Eta Carinae was faint and undistinguished. In the first decades of the century, it became brighter and brighter, until, by April 1843, it was the second brightest star in the sky, outshone only by Sirius (which is almost a thousand times closer to Earth). In the years that followed, it gradually dimmed again and by the 20th century was totally invisible to the naked eye. The star has continued to vary…
