NASA’s Hubble Revisits Crab Nebula to Track 25 Years of Expansion

A quarter-century after its first observations of the full Crab Nebula, NASA’s Hubble Space Telescope has taken a fresh look at the supernova remnant. The result is an unparalleled, detailed look at the aftermath of a supernova and how it has evolved over Hubble’s long lifetime. A paper detailing the new Hubble observation is published […]

Cassiopeia A, Then the Cosmos: 25 Years of Chandra X-ray Science

By Rick Smith On Aug. 26, 1999, NASA’s Chandra X-ray Observatory opened its powerful telescopic eye in orbit and captured its awe-inspiring “first light” images of Cassiopeia A, a supernova remnant roughly 11,000 light-years from Earth.

Investigating the Origins of the Crab Nebula With NASA’s Webb

New data revises our view of this unusual supernova explosion. A team of scientists used NASA’s James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.

NASA’s Chandra Releases Doubleheader of Blockbuster Hits

New movies of two of the most famous objects in the sky — the Crab Nebula and Cassiopeia A — are being released from NASA’s Chandra X-ray Observatory. Each includes X-ray data collected by Chandra over about two decades. They show dramatic changes in the debris and radiation remaining after the explosion of two massive […]
