Hubble Sees Sparring Antennae Galaxies: The NASA/ESA Hubble Space Telescope has snapped the best ever image of the Antennae Galaxies. Hubble has released images of these stunning galaxies twice before, once using observations from its Wide Field and Planetary Camera 2 (WFPC2) in 1997, and again in 2006 from the Advanced Camera for Surveys (ACS). Each of Hubble’s images of the Antennae Galaxies has been better than the last, due to upgrades made during the famous servicing missions, the last of which took place in 2009.

The galaxies — also known as NGC 4038 and NGC 4039 — are locked in a deadly embrace. Once normal, sedate spiral galaxies like the Milky Way, the pair have spent the past few hundred million years sparring with one another. This clash is so violent that stars have been ripped from their host galaxies to form a streaming arc between the two. In wide-field images of the pair the reason for their name becomes clear — far-flung stars and streamers of gas stretch out into space, creating long tidal tails reminiscent of antennae.

This new image of the Antennae Galaxies shows obvious signs of chaos. Clouds of gas are seen in bright pink and red, surrounding the bright flashes of blue star-forming regions — some of which are partially obscured by dark patches of dust. The rate of star formation is so high that the Antennae Galaxies are said to be in a state of starburst, a period in which all of the gas within the galaxies is being used to form stars. This cannot last forever and neither can the separate galaxies; eventually the nuclei will coalesce, and the galaxies will begin their retirement together as one large elliptical galaxy.

This image uses visible and near-infrared observations from Hubble’s Wide Field Camera 3 (WFC3), along with some of the previously-released observations from Hubble’s Advanced Camera for Surveys (ACS).

ISON, Mars, Regulus

In order top to bottom this celestial snapshot features Comet ISON, planet Mars, and Regulus, alpha star of the constellation Leo, in the same frame. The scene spans about 2 degrees near the eastern horizon in early morning skies of October 15. Closest of the three, the much heralded Comet ISON (C/2012 S1) is by far the faintest at 14 light-minutes (1.7 AU) away. Mars is only slightly farther from our fair planet. About 16.5 light minutes (2 AU) away its normal ruddy color is washed out in the exposure. Regulus outshines both comet and planet from a distance of 75 light-years. Just above Regulus, the very faint smudge of light is actually the Leo I dwarf galaxy, 800,000 light-years away and almost lost in the glare of the bluish hued bright star. Comet ISON is expected to grow brighter, though. How bright is still not clear, but not as bright as a Full Moon in night skies. Estimated to be 1 to 4 kilometers in diameter, ISON's nucleus might substantially survive its very close encounter with the Sun on November 28. If so, the comet will climb back above the eastern horizon in planet Earth's northern hemisphere before dawn in early December.

The first of a set of unprecedented, super-deep views of the universe from an ambitious collaborative program called The Frontier Fields is being released today at the 223rd meeting of the American Astronomical Society in Washington, D.C.

The long-exposure image taken with NASA's Hubble Space Telescope is the deepest-ever picture taken of a cluster of galaxies, and contains images of some of the intrinsically faintest and youngest galaxies ever detected.

Stop whatever you're doing and click this! Seriously. It is simply the most stunning and wondrous picture of Saturn I have ever seen — a mosaic of Cassini images put together by Gordan Urgakovic. Make sure you grab the high-res version, then read along as I take you on a tour of what you're seeing.

Holy wow.
