Image of the Day: The Cosmic Tsunami of a Galactic Quintet

Written by

CaseyKazan on

From: www.dailygalaxy.com

This false-color composite image of the Stephan's Quintet galaxy cluster clearly shows one of the largest shock waves ever seen (the green arc above), produced by one galaxy falling toward another at over a million miles per hour. It is made up of data from NASA's Spitzer Space Telescope and a ground-based telescope in Spain. What makes the Stephan's Quintet of galaxies so fascinating are the rare red blobs found in NGC 7320, the brightest of the group. These extensive red H II regions have hyper active star formation. Space telescopes have recently provided new insight into the nature of the strange green filament, ... Read Full Story

12 totally awesome Google Maps

From: news.cnet.com

I was looking through the Google Maps directory recently and found a variety of maps worth checking out. From up-to-date weather to barbershops, they should all be added to your list of Google Maps modules. Barbershops : The map's description says "Barbershops are one of the last bastions of manliness today." And that's why the developer created a map providing locations to barbershops all over the U.S. Not every area is covered, but if you live in a major city, you'll find at least one or two barbershops to try out. Best nightclubs in NYC. (Credit: Don Reisinger/CNET) Best Nightclubs and Bars : If ... Read Full Story

Gehrz [ VIA National Geographic] A product of cosmic collaboration, this new picture of the Crab Nebula combines data from the Chandra X-ray Observatory , the Hubble Space Telescope, and the Spitzer Space Telescope. The nebula is the remnant of a stellar explosion 6,000 light-years from Earth that was so powerful people saw the burst in A.D. 1054, according to NASA. Infrared light caught by Spitzer and visible light seen by Hubble paint the nebula's expanding debris cloud in shades of purple and red. Meanwhile, Chandra's x-ray vision ... Read Full Story

Eposode 35: Accreting Black Hole

Written by

From: epo.sonoma.edu

New episode every Monday! What does it mean? Accretion Disk – A disk of matter that forms when material is transferred to a gravitationally massive body, such a black hole. For black holes, the disks form outside the event horizons. For other objects, such as neutron stars or white dwarfs, the disks can extend down to the stellar surfaces. Friction and other forces heat the disks, which then emit a a wide range of different types of electromagnetic radiation including x-rays. In human speak please! Our atmosphere blocks x-rays from reaching the surface of the Earth. In the 1960s, scientists sent rockets above the ... Read Full Story

12/16/08: Chandra Observes Effects of Dark Energy on Galaxy Cluster Growth.

Written by

astronaut on

From: weatherspace.org

For the first time, astronomers have clearly seen the effects of ‘dark energy’ on the most massive collapsed objects in the Universe, using NASA’s Chandra X-ray Observatory. By tracking how dark energy has stifled the growth of galaxy clusters and combining this with previous studies, scientists have obtained the best clues yet about what dark energy is and what the destiny of the Universe could be. This work, which took years to complete, is separate from other methods of dark energy research such as supernovas. These new X-ray results provide a crucial independent test of dark energy, long sought by scientists, which depends on ... Read Full Story
