Since their first discovery in the 1960s, over 2,000 pulsars, rapidly spinning, dense stellar cores, have been found. Data from NASA's Chandra X-ray Observatory has confirmed the youngest known pulsar in our Milky Way galaxy. This pulsar, known as Kes 75, is located about 19,000 light years from Earth. Scientists have uncovered interesting properties of Kes 75 that could help them better understand how some stars end their lives.
NGC 2392 is a planetary nebula, a phase that results when a star like the sun becomes a red giant and sheds its outer layers. X-rays from Chandra (pink) shows superheated gas around the dense, hot core of the star. Our Sun will become a planetary nebula about 5 billion years from now.

A new Chandra image of SN 1006 provides new details about the remains of an exploded star. This explosion was witnessed from Earth over a millennium ago. The Chandra data provides the best map to date of the debris field including information on important elements expanding into space. SN 1006 belongs to a class of supernova used to measure the expansion of the Universe.
Flocculent spiral NGC 2841.
A new composite of NGC 4258 features X-rays from Chandra (blue), radio waves from the VLA (purple), optical data from Hubble (yellow and blue), and infrared with Spitzer (red). NGC 4258 is well known to astronomers for having "anomalous" arms that are not aligned with the plane of the galaxy, but rather intersect with it. Researchers are trying to understand how the giant black hole in the center of NGC 4258 is affecting the rest of the galaxy. NGC 4258, also known as Messier 106, is located about 23 million light years from Earth.
