A newly formed neutron star (small white dot) sits in the center of the supernova remnant Cassiopeia A, about 11,000 light-years away, in this image from NASA’s Chandra X-ray Observatory. Measurements of a form of zinc on Earth have given researchers new clues to the composition of neutron stars.

The Eye of God: Six hundred and fifty light-years away in the constellation Aquarius, a dead star about the size of Earth, is refusing to fade away peacefully. NASA's Hubble and Spitzer Space Telescopes have captured the complex structure of the Helix nebula. Credit: NASA/JPL-Caltech/ESA

(NASA - Supernova Remnant W49B:    The highly distorted supernova remnant shown in this image may contain the most recent black hole formed in the Milky Way galaxy. The image combines X-rays from NASA's Chandra X-ray Observatory in blue and green, radio data from the NSF's Very Large Array in pink, and infrared data from Caltech's Palomar Observatory in yellow.     The remnant is about a thousand years old, as seen from Earth, and is at a distance about 26,000 light years away.

A beautiful new image of two colliding galaxies has been released by NASA's Great Observatories. The Antennae galaxies, located about 62 million light-years from Earth, are shown in this composite image from the Chandra X-ray Observatory (blue), the Hubble Space Telescope (gold and brown), and the Spitzer Space Telescope (red).

Located 10,000 light-years away in the northern constellation Cassiopeia, Cassiopeia A is the remnant of a once massive star that died in a violent supernova explosion 325 years ago. It consists of a dead star, called a neutron star, and a surrounding shell of material that was blasted off as the star died. The neutron star can be seen in the Chandra data as a sharp turquoise dot in the center of the shimmering shell.
