NASA’s IXPE Reveals X-ray-Generating Particles in Black Hole Jets

The blazar BL Lacertae, a supermassive black hole surrounded by a bright disk and jets oriented toward Earth, provided scientists with a unique opportunity to answer a longstanding question: How are X-rays generated in extreme environments like this? NASA’s IXPE (Imaging X-ray Polarimetry Explorer) collaborated with radio and optical telescopes to find answers. The results […]

NASA’s Chandra Diagnoses Cause of Fracture in Galactic “Bone”

Astronomers have discovered a likely explanation for a fracture in a huge cosmic “bone” in the Milky Way galaxy, using NASA’s Chandra X-ray Observatory and radio telescopes. The bone appears to have been struck by a fast-moving, rapidly spinning neutron star, or pulsar. Neutron stars are the densest known stars and form from the collapse and explosion of massive stars. They […]

NASA’s Chandra Releases New 3D Models of Cosmic Objects

New three-dimensional (3D) models of objects in space have been released by NASA’s Chandra X-ray Observatory. These 3D models allow people to explore — and print — examples of stars in the early and end stages of their lives. They also provide scientists with new avenues to investigate scientific questions and find insights about the […]

Understanding Cosmic Explosions: StarBurst Arrives at NASA for Testing

StarBurst, a wide-field gamma ray observatory, arrived at NASA’s Marshall Space Flight Center in Huntsville, Alabama, March 4 for environmental testing and final instrument integration. The instrument is designed to detect the initial emission of short gamma-ray bursts, a key electromagnetic indicator of neutron star mergers. “Gamma-ray bursts are among the most powerful explosions in […]

Finding Clues in Ruins of Ancient Dead Star With NASA’s Chandra

People often think about archaeology happening deep in jungles or inside ancient pyramids. However, a team of astronomers has shown that they can use stars and the remains they leave behind to conduct a special kind of archaeology in space. Mining data from NASA’s Chandra X-ray Observatory, the team of astronomers studied the relics that […]

X-ray Signal Points to Destroyed Planet, Chandra Finds

A planet may have been destroyed by a white dwarf at the center of a planetary nebula — the first time this has been seen. As described in our latest press release, this would explain a mysterious X-ray signal that astronomers have detected from the Helix Nebula for over 40 years. The Helix is a […]
