Host Galaxy Cluster to Largest Known Radio Eruption |
| General Information |
What is a News Nugget? News Nuggets are bulletins from the world of astronomy. This is a new composite image of galaxy cluster MS0735.6+7421, located about 2.6 billion light-years away in the constellation Camelopardalis. The three views of the region were taken with NASA's Hubble Space Telescope in Feb. 2006, NASA's Chandra X-ray Observatory in Nov. 2003, and NRAO's Very Large Array in Oct. 2004. The Hubble image shows dozens of galaxies bound together by gravity. In Jan. 2005, astronomers reported that a supermassive black hole, lurking in the central bright galaxy, generated the most powerful outburst seen in the universe. The VLA radio image shows jets of high energy particles (in red) streaming from the black hole. These jets pushed the X-ray emitting hot gas (shown in blue in the Chandra image) aside to create two giant cavities in the gas. The cavities are evidence for the massive eruption. The X-ray and radio images show the enormous appetite of large black holes and the profound impact they have on their surroundings. |

NGC 1569: Starburst in a Small Galaxy |
| Explanation |
Grand spiral galaxies [ http://antwrp.gsfc.nasa.gov/apod/ap030524.html ] often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral [ http://antwrp.gsfc.nasa.gov/apod/ap030925.html ] arms. But small, irregular [ http://antwrp.gsfc.nasa.gov/apod/ap010804.html ] galaxies form stars too. In fact, as pictured here [ http://hubble.esa.int/science-e/www/object/ index.cfm?fobjectid=34594 ], dwarf galaxy NGC 1569 is apparently undergoing a burst of star forming activity, thought to have begun over 25 million years ago. The resulting turbulent environment [ http://antwrp.gsfc.nasa.gov/apod/ap020725.html ] is fed by supernova explosions as the cosmic detonations spew out material and trigger further star formation. Two massive star clusters - youthful counterparts to globular star clusters [ http://www.seds.org/messier/xtra/supp/mw_gc.html ] in our own spiral Milky Way [ http://www.anzwers.org/free/universe/ galaxy.html ] galaxy - are seen left of center in the gorgeous Hubble Space Telescope [ http://hubblesite.org ] image. The picture spans about 1,500 light-years across NGC 1569. A mere 7 million light-years distant, this relatively close starburst galaxy offers astronomers an excellent opportunity to study [ http://arxiv.org/abs/astro-ph/0309153 ] stellar populations in rapidly evolving galaxies. NGC 1569 lies in the long-necked [ http://www.nature-wildlife.com/girtxt.htm ] constellation Camelopardalis [ http://www.dibonsmith.com/cam_con.htm ]. |

| Title |
A Supernova in Nearby Galaxy NGC 2403 |
| Explanation |
The closest and brightest supernova in over a decade was recorded [ http://www.berkeley.edu/news/media/releases/2004/09/02_TypeIISN.shtml ] just over a month ago in the outskirts of nearby galaxy NGC 2403. Officially tagged SN 2004dj [ http://www.rochesterastronomy.org//sn2004/sn2004dj.html ], the Type IIP [ http://www2.arnes.si/~gljsentvid10/supn1.html ] explosion likely annihilated most of a blue supergiant star [ http://antwrp.gsfc.nasa.gov/apod/ap001222.html ] as central fusion [ http://zebu.uoregon.edu/~js/ast122/lectures/lec14.html ] could no longer hold it up [ http://antwrp.gsfc.nasa.gov/htmltest/gifcity/msblues.html ]. The supernova [ http://heasarc.gsfc.nasa.gov/docs/snr.html ] can be seen as the bright object in the above image [ http://hubblesite.org/newscenter/newsdesk/archive/releases/2004/23/ ] in the direction of the arrow. The home galaxy to the supernova, spiral galaxy NGC 2403 [ http://www.seds.org/messier/xtra/ngc/n2403.html ], is located only 11 million light years [ http://starchild.gsfc.nasa.gov/docs/StarChild/questions/question19.html ] away and is visible with binoculars toward the northern constellation [ http://www.astro.wisc.edu/~dolan/constellations/extra/constellations.html ] of Camelopardalis [ http://www.astronomical.org/portal/modules/wfsection/article.php?articleid=11 ] (the Giraffe [ http://www.kidsplanet.org/factsheets/giraffe.html ]). The supernova is fading [ http://www.rochesterastronomy.org/supernova.html ] but still visible with a telescope, once peaking at just brighter than magnitude [ http://csep10.phys.utk.edu/astr162/lect/stars/magnitudes.html ] 12. Supernovas [ http://cfa-www.harvard.edu/iau/lists/Supernovae.html ] of this type change brightness in a predictable way and may be searched for in the distant universe [ http://antwrp.gsfc.nasa.gov/apod/ap040309.html ] as distance indicators. |
