http://hubblesite.org/newscenter/archive/releases/1996/22/text/ Probing the mysterious heart of the Crab Nebula, the tattered remains of a stellar cataclysm witnessed more than 900 years ago, astronomers using NASA's Hubble Space Telescope have found that the Crab is even more dynamic than previously understood, based on a cosmic "movie" assembled from a series of Hubble observations. ... Because of this flickering, the neutron star is also called a "pulsar." ...

... This meteor shower, which reaches a peak of up to 120 meteors per hour, as seen from a clear, dark site, can be observed anytime after about 10.00pm for a few nights either side of the maximum, that is from about the 12 to 16 December. The Geminid meteors, which sometimes appear as brightly coloured relatively slow-moving fireballs, are caused by small particles mostly about the size of marbles or smaller, ejected into space from the surface of the near-Earth asteroid Phaethon . ...

This image shows the ALMA data overlaid on an artist s impression background. The ALMA data show two main cores as imaged by emission from the molecular ion N2D+ (two nitrogen and one deuterium atom). The core on the right is particularly bright and rounded, suggesting it is self-gravitating and poised to form a massive, single star a very rare occurrence in star formation. ...

Estimating the NEO Population and Impact Risk: Past, Present and Future . ... Since most of the risk resides in the largest impactors, finding that fraction of the largest bodies, and that none of them has a significant chance of impacting in the next century or so, "retires" more than 90 % of the impact risk, including most of the risk of a globally catastrophic impact event. ... In the mid-size range, from ~150 m to ~1 km, the main risk is from tsunami generated by an ocean impact. ...
