Youngest Exploding Star Discovered
The remnant known as G1.9+0.3 (shown here) came from the most recent supernova in our galaxy. To determine the age of the stellar explosion, astronomers tracked how quickly the remnant was expanding, by comparing a radio image from 1985 (blue) to an X-ray image taken in 2007 (orange).
Galaxy's Ghostly Arms Finally Explained
In this composite image of spiral galaxy M106, optical data is shown as yellow, radio data from the Very Large Array appears as purple, X-ray data from Chandra is coded blue and infrared data from the Spitzer Space Telescope appears red. The anomalous arms appear as purple and blue emission.
On 10th Birthday, Chandra Spies Stellar Explosion
This composite image of X-ray and optical data shows the remnant of supernova 1E 0102.2-7219, about 190,000 light-years away in the Small Magellanic Cloud.
Arp 147 galaxies
This image of the two galaxies that form Arp 147 shows a vast cosmic ring of stars (blue) and black holes (pink) as seen by the Chandra X-ray Observatory and Hubble Space Telescope. Another galaxy is also visible (vertical at left), as well as a bright star and quasar (pink object at upper left). This image was released on Feb. 9, 2011.
Colossal Cosmic Collision Reveals Mysterious Dark Matter
Hot gas detected by Chandra in X-rays is seen as two pink clumps that contain most of the normal matter in the two clusters. The bullet-shaped clump on the right is hot gas from one cluster, which passed through the hot gas from the other larger cluster. Other telescopes were used to detect the bulk of the matter in the clusters, which turns out to be dark matter (highlighted in blue).
Black Hole Belts Out Discordant Musical
This Chandra image of M87 shows high energy X-rays. The faint, outer ring is about 85,000 light years across and gives an unambiguous signature of a weak shock wave (like a sonic boom) generated by an outburst from the supermassive black hole at the center of M87. The properties of the shock, including the change in temperature and density in the gas, are consistent with classical physics. The bright yellow, inner ring may be the gas just outside the "piston" that is powering the shock further out, and the ring in the middle was probably produced by another outburst.
Scientists Discover Stellar Bombs with Short Fuses
EM L238 and DEM L249 are two supernova remnants in the Large Magellanic Cloud. X-ray data from NASA's Chandra and ESA's XMM-Newton observatories suggest that the stars responsible for these debris fields were unusually young when they were destroyed by thermonuclear explosions.

Slow-spinning Pulsar SXP 1062
The slow-spinning X-ray pulsar SXP 1062 shines brightly from within the shell of gas and dust rushing away from the supernova that formed it.
