Sagittarius A*

A sixteen year long astronomical study, led by Dr. Reinhard Genzel of the Max-Planck-Institute for Extraterrestrial Physics, has provided what is considered to be the best empirical evidence yet of the existence of supermassive black holes, specifically one a relatively cozy 27,000 light years away.... "The stellar orbits [QT] in the Galactic Centre [QT] show that the central mass concentration of four million solar masses must be a black hole, beyond any reasonable doubt." [more inside]

Not the Ford Galaxy

Five years and 800,000 images went into producing a 4 gigapixel mosaic image of the galactic plane, which when printed out is 180 feet long. But it has been made browser-sized by GLIMPSE, the Galactic Legacy Infrared Mid-Plane Survey Extraordinaire, the research group which, along with MIPSGAL, created the image: A Glimpse of the Milky Way.

Orders of Magnitude

Leave the planet to travel into the largest structures of the universe, then plunge into the tiniest. Forty two orders of magnitude in thirty six minutes.... Cosmic Voyage. (single link Google video via) [more inside]

A Star is Unborn

“Here was an object brand new. At first we didn’t recognize it.” Dr. Alicia Soderberg on the discovery of Supernova 2008D, using the Swift satellite telescope....

Gravitic Mayhem

" It looks as if our Milky Way will be subsumed into its giant neighbour, the Andromeda galaxy...." A (not so) little trove of images of galactic collisions has been released to mark the 18th anniversary of the Hubble telescope's launch. Gravitic Mayhem. (via)

You're not alone

Many planets have been found circling other stars, but the prevailing search techniques turn up results encouraging but bizarre. (encouraging, previously) Gravitational micro-lensing has made it possible to OGLE a solar system much like our own.... You're not alone.
