Learn About Stars (02-21-2013)
Stars appear to be permanent fixtures of the night sky. However, stars are like people. They are born, live a lifetime, and ultimately die.

W49B in 60 Seconds (02-14-2013)
The supernova remnant known as W49B is, let's say, a bit unorthodox looking. Many supernova remnants appear rather spherical in shape.

Learn About Solar System (02-07-2013)
One star, eight planets, and a myriad of moons, comets and asteroids. This is the Earth's local neighborhood, known as the Solar System.

Ice Core Records: From Volcanoes to Supernovas (Part II) (02-04-2013)
While astronomers know that Cassiopeia A, or Cas A for short, is the aftermath of a massive star that exploded, it is unclear exactly when the explosion took place.

DEM L50 in 60 Seconds (02-01-2013)
DEM L50 is what astronomers call a superbubble. These objects are found in regions where massive stars have formed, raced through their evolution, and exploded as supernovas.

Chandra Images in 2012 (01-08-2013)
The Chandra images included in this short 2012 retrospective are drawn from dozens of images posted on our website (from among hundreds taken) in the past year to show the breadth and depth of research done using Chandra.

Vela Pulsar in 60 Seconds (01-07-2013)
Unlike with some Hollywood films, a sequel of a movie from NASA's Chandra X-ray Observatory is better than the first.

Learn About Supernovas (01-03-2013)
Supernovas are some of the most dramatic events in the cosmos. These titanic events send shockwaves rumbling through space and create giant bubbles of gas that have been superheated to millions of degrees.

Learn About Black Holes (12-27-2012)
If a star has three times or more the mass of the sun and collapses, it can form a black hole.

A Bend in the Road (12-20-2012)
There are many things around us that bend. Straws bend. Rivers bend. But did you know that light also bends?
