Supernova Survivor (Feb 12 2004) Credit: Justyn R. Maund (IoA/Univ. Cambridge) et al., ESA Inset Left: Isaac Newton Telescope, Bottom: Hubble WFPC2, Right: Hubble ACS Beginning with a full view of beautiful spiral galaxy M81, follow the insets (left, bottom, then right) to zoom in on a real survivor. Seen at the center of the final field on the right is a star recently identified as the survivor of a cosmic cataclysm -- the supernova explosion of its companion star. #astronomy
SN 2006GY: Brightest Supernova (May 10 2007) Credit: X-ray: NASA / CXC, Nathan Smith, Weidong Li (UC Berkeley) et al.; IR: PAIRITEL/Lick/UC Berkeley/J.Bloom, C.Hansen The stellar explosion cataloged as supernova SN 2006gy shines in this wide-field image (left) of its host galaxy, NGC 1260, and expanded view (upper right panel) of the region surrounding the galaxy's core. In fact, given its estimated distance of 240 million light-years, SN 2006gy was brighter than (...) #astronomy
December 12, 1997: Phi Persei: Double Star Credit: D. Gies (CHARA, GSU) et. al. Illustration: W. Pounds Explanation: It's clear who is the biggest star in this binary system. Based on recent results, this artist's vision of the double star Phi Persei, 720 light years away, shows a bright, rapidly rotating massive star surrounded by a disk of gas. A small companion star orbits 100 million miles away. The bigger star is presently about 9 times more massive than the small one... More...
The Double Cluster (Dec 4 2009) Credit & Copyright: Neil Fleming A lovely starfield in the heroic northern constellation Perseus holds this famous pair of open or galactic star clusters, h and Chi Perseii. Also cataloged as NGC 869 (right) and NGC 884, both clusters are about 7,000 light-years away and contain stars much younger and hotter than the Sun. Separated by only a few hundred light-years, the clusters' ages based on their individual stars are similar. #astronomy

A Nearby Supernova in Spiral Galaxy M100 (Mar 7 2006) Credit: FORS Team, 8.2-meter VLT, ESO One of the nearer supernovas of recent years was discovered last month in the bright nearby galaxy M100. The supernova, dubbed SN 2006X, is still near its maximum brightness and visible with a telescope toward the constellation of Berenice's Hair (Coma Berenices) #astronomy
Comet Meets Ring Nebula: Part I (May 11 2006) Credit & Copyright: Stefan Seip and Steffen Bruckner As dawn approached on May 8, astronomer Stefan Seip carefully watched Fragment C of broken comet 73P/Schwassmann-Wachmann 3 approach M57 - the Ring Nebula, and faint spiral galaxy IC 1296. Of course, even though the trio seemed to come close together in a truly cosmic photo opportunity, the comet is in the inner part of our solar system, a mere 0.5 light-minutes or so from Seip's telescope…
