NASA's Chandra catches pulsar in X-ray speed trap

A young pulsar is blazing through the Milky Way at a speed of over a million miles per hour. This stellar speedster, witnessed by NASA's Chandra X-ray Observatory, is one of the fastest objects of its kind ever seen. This ...

Black holes raze thousands of stars to fuel growth

In some of the most crowded parts of the universe, black holes may be tearing apart thousands of stars and using their remains to pack on weight. This discovery, made with NASA's Chandra X-ray Observatory, could help answer ...

Tiny star unleashes gargantuan beam of matter, anti-matter

Astronomers have imaged a beam of matter and antimatter that is 40 trillion miles long with NASA's Chandra X-ray Observatory. The record-breaking beam is powered by a pulsar, a rapidly rotating collapsed star with a strong ...

Exploring astronomy with X-rays

The recent launches of the James Webb Space Telescope (Webb) and the Imaging X-ray Polarimetry Explorer (IXPE) by NASA and its international partners are excellent reminders that the universe emits light or energy in many ...

Astronomers spy quartet of cavities from giant black holes

Scientists have found four enormous cavities, or bubbles, at the center of a galaxy cluster using NASA's Chandra X-ray Observatory. This unusual set of features may have been caused by eruptions from two supermassive black ...

KPD 0005+5106: Roasted and shredded by a stellar sidekick

An exhausted star still has some punches to deliver. Astronomers have found that a white dwarf is pummeling a companion object—either a lightweight star or a planet—with incessant blasts of heat and radiation plus a relentless ...

G344.7-0.1: When a stable star explodes

White dwarfs are among the most stable of stars. Left on their own, these stars that have exhausted most of their nuclear fuel—while still typically as massive as the Sun—and shrunk to a relatively small size can last ...

Chandra resumes science operations

NASA's Chandra X-ray Observatory has successfully resumed observations after recovery from a problem involving one of its science instruments, the Low Energy Transmission Grating (LETG). The LETG is used to measure the intensity ...
