Chandra Stories

A quarter of a century ago, NASA released the “first light” images from the agency’s Chandra X-ray Observatory. This introduction to the world of Chandra’s high-resolution X-ray imaging capabilities included an unprecedented view of Cassiopeia A, the remains of an…

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. That first observation was far…

NASA’s Universe of Learning – a partnership among the Space Telescope Science Institute (STScI), Caltech/IPAC, the Center for Astrophysics | Harvard & Smithsonian, and the Jet Propulsion Laboratory and part of the NASA Science Activation program portfolio – recently released…

By Rick Smith “The art of aerospace engineering is a matter of seeing around corners,” said NASA thermal analyst Jodi Turk. In the case of NASA’s Chandra X-ray Observatory, marking its 25th anniversary in space this year, some of those…

To celebrate the 25th anniversary of its launch, NASA’s Chandra X-ray Observatory is releasing 25 never-before-seen views of a wide range of cosmic objects. These images, which all include data from Chandra, demonstrate how X-ray astronomy explores all corners of the universe.…

This graphic shows a three-dimensional map of stars near the Sun. These stars are close enough that they could be prime targets for direct imaging searches for planets using future telescopes. The blue haloes represent stars that have been observed…

A new project provides special 3D “experiences” on Instagram using data from NASA’s Chandra X-ray Observatory and other telescopes through augmented reality (AR), allowing users to travel virtually through objects in space. These new experiences of astronomical objects – including…

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…

Three new sonifications of images from NASA’s Chandra X-ray Observatory and other telescopes have been released in conjunction with a new documentary about the project that makes its debut on the NASA+ streaming platform. Sonification is the process of translating…

Researchers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have discovered X-ray activity that sheds light on the evolution of galaxies. The X-rays outline giant clouds of cold gas in the nearby spiral galaxy NGC 4945. The gas appears…
