NASA Telescopes Spot Surprisingly Mature Cluster in Early Universe

A new discovery captures the cosmic moment when a galaxy cluster – among the largest structures in the universe – started to assemble only about a billion years after the big bang, one or two billion years earlier than previously thought. This result, made using NASA’s Chandra X-ray Observatory and James Webb Space Telescope, will […]

NASA’s Chandra Releases Deep Cut From Catalog of Cosmic Recordings

Like a recording artist who has had a long career, NASA’s Chandra X-ray Observatory has a “back catalog” of cosmic recordings that is impossible to replicate. To access these X-ray tracks, or observations, the ultimate compendium has been developed: the Chandra Source Catalog (CSC).

Supernova Remnant Video From NASA’s Chandra Is Decades in Making

A new video shows the evolution of Kepler’s Supernova Remnant using data from NASA’s Chandra X-ray Observatory captured over more than two and a half decades. Kepler’s Supernova Remnant, named after the German astronomer Johannes Kepler, was first spotted in the night sky in 1604. Today, astronomers know that a white dwarf star exploded when […]

NASA’s Chandra Rings in New Year With Champagne Cluster

Celebrate the New Year with the “Champagne Cluster,” a galaxy cluster seen in this new image from NASA’s Chandra X-ray Observatory and optical telescopes. Astronomers discovered this galaxy cluster Dec. 31, 2020.

NASA IXPE’s Longest Observation Solves Black Hole Jets Mystery

Written by Michael Allen An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer) has identified the origin of X-rays in a supermassive black hole’s jet, answering a question that has been unresolved since the earliest days of X-ray astronomy.

Mapping Dark Matter

This image released on June 30, 2025, combines data from NASA’s James Webb Space Telescope and NASA’s Chandra X-ray Observatory to visualize dark matter. Researchers used Webb’s observations to carefully measure the mass of the galaxy clusters shown here as well as the collective light emitted by stars that are no longer bound to individual […]

Data from NASA’s Chandra X-ray Observatory and NASA’s James Webb Space Telescope combine to reveal an otherworldly view of the star-forming region IC 348. In this image released on July 23, 2025, X-rays from Chandra are red, green, and blue, while infrared data from Webb are pink, orange, and purple. The wispy structures that dominate […]

NASA’s Chandra Finds Black Hole With Tremendous Growth

A black hole is growing at one of the fastest rates ever recorded, according to a team of astronomers. This discovery from NASA’s Chandra X-ray Observatory may help explain how some black holes can reach enormous masses relatively quickly after the big bang. The black hole weighs about a billion times the mass of the […]

Westerlund 1, the biggest and closest “super” star cluster to Earth, dazzles in this image released on July 23, 2025. This view combines x-ray data from NASA’s Chandra X-ray Observatory (in pink, blue, purple, and orange), infrared data from NASA’s James Webb Space Telescope (in yellow, gold, and blue), and optical data from NASA’s Hubble […]

NASA’s Chandra Shares a New View of Our Galactic Neighbor

The Andromeda galaxy, also known as Messier 31 (M31), is the closest spiral galaxy to the Milky Way at a distance of about 2.5 million light-years. Astronomers use Andromeda to understand the structure and evolution of our own spiral, which is much harder to do since Earth is embedded inside the Milky Way. The galaxy […]
