From exploding stars to black holes to clusters of galaxies, explore recent science highlights from NASA's Chandra X-ray Observatory. This app provides a selection of Chandra’s astronomical images to zoom into, share, and learn about. Drawing directly from our database of Chandra observations, the Chandra team will be increasing the selection, and adding multiwavelength functionality and additional interactivity in future updates.

About the Chandra mission: Since its launch on July 23, 1999, the Chandra X-ray Observatory has been NASA's flagship mission for X-ray astronomy, taking its place in the fleet of "Great Observatories." Chandra has imaged the spectacular, glowing remains of exploded stars, and taken spectra showing the dispersal of elements. Chandra has observed the region around the supermassive black hole in the center of our Milky Way, and found black holes across the Universe. Chandra has traced the separation of dark matter from normal matter in the collision of galaxies in a cluster and is contributing to both dark matter and dark energy studies. As its mission continues, Chandra will continue to discover startling new science about our high-energy Universe.

Beautiful images and a wealth of information!

I love this Chandra app! It's easy to use, with a ton of info on several images just a tap or two away. These images are breathtaking, and the science behind them awe-inspiring! Here's to many more years of discovery with the Chandra telescope!
