NGC 602: Taken Under the "Wing" of the Small Magellanic Cloud
http://chandra.si.edu/photo/2013/ngc602/

New Chandra observations have been used to make the first detection of X-ray emission from young stars with masses similar to our Sun outside our Milky Way galaxy. The Chandra observations of these low-mass stars were made of the region known as the "Wing" of the Small Magellanic Cloud (SMC), one of the Milky Way's closest galactic neighbors. In this composite image of the Wing the Chandra data is shown in purple, optical data from the Hubble Telescope is shown in red, green and blue and infrared data from the NASA's Spitzer Space Telescope is shown in red. Astronomers call all elements heavier than hydrogen and helium—that is, with more than two protons in the atom's nucleus—"metals". The Wing is a region known to have fewer metals compared to most areas within the Milky Way. The Chandra results imply that the young, metal-poor stars in NGC 602a produce X-rays in a manner similar to stars with much higher metal content found in the Orion cluster in our galaxy.

Chandra Flashback of the Day

N132D: NASA Space Observatories Glimpse Faint Afterglow of Nearby Stellar Explosion  
http://chandra.harvard.edu/photo/2005/n132d/

This is a composite Chandra (X-ray/blue) and Hubble (optical/pink & purple) of N132D. The beautiful glowing horseshoe-shaped cloud of hot gas against a backdrop of thousands of stars was produced by the explosion of a massive star. Shock waves produced by the explosion heated interstellar gas around the site to X-ray emitting temperatures of millions of degrees Celsius. The optical image reveals cooler gas and a small, bright crescent-shaped cloud of emission from hydrogen gas. The star that exploded as a supernova was probably more than 20 times as massive as the Sun. Most of the stars in this image are less massive and will not go out with a bang.

Chandra Flashback of the Day

Galactic Center: New Vista of Milky Way Center Unveiled
http://chandra.harvard.edu/photo/2009/gcenter/

This Chandra image exposes a wealth of exotic objects and high-energy features at the center of our galaxy, the Milky Way. In this new and deep image from Chandra, red represents lower-energy X-rays, green shows the medium range, and blue indicates the higher-energy X-rays. Hundreds of small dots show emission from material around black holes, neutron stars and white dwarfs. A supermassive black hole -- some four million times more massive the Sun -- resides within the bright, blue-white region on the right. The diffuse X-ray light comes from gas heated to millions of degrees by outflows from the supermassive black hole, winds from giant stars, and stellar explosions.

Astronomers have finally solved the longstanding cosmic mystery of why a super-dense gas cloud near our Milky Way galaxy's core, seen below, isn't churning out many new stars. http://oak.ctx.ly/r/1vfg
