Nearby Star’s Icy Debris Suggests ‘Shepherd’ Planet And Rapid-Fire Comet Collisions  An international team of astronomers exploring the disk of gas and dust around a nearby star have uncovered a compact cloud of poisonous gas formed by ongoing rapid-fire collisions among a swarm of icy, comet-like bodies

Hubble Uncovers Largest Known Group Of Star Clusters, Clues To Dark Matter  “The globular clusters are fossils of the earliest star formation in Abell 1689, and our work shows they were very efficient in forming in the denser regions of dark matter near the center of the galaxy cluster,” Blakeslee said. “Our findings are consistent with studies of globular clusters in other galaxy clusters, but extend our knowledge to regions of higher dark matter density.”

Looking Back To The Cradle Of Our Universe  The zoomed image shows the region around the galaxy Abell2744_Y1, one of the most distant galaxy candidates known, harkening back to a time when the universe was 650 million years old. NASA’s Spitzer Space Telescope helped to narrow in on the galaxy’s great distance.

Galaxies, Comets, and Stars! Oh My!  In this Hubble Space Telescope composite image taken in April 2013, the sun-approaching Comet ISON floats against a seemingly infinite backdrop of numerous galaxies and a handful of foreground stars. The icy visitor, with its long gossamer tail, appears to be swimming like a tadpole through a deep pond of celestial wonders.

This is a Digitized Sky Survey image of the oldest star with a well-determined age in our galaxy. The aging star, cataloged as HD 140283, lies 190.1 light-years away.
