The monster black hole at the center of our galaxy may be unleashing huge, gassy explosions — and now, astronomers think they’ve pinpointed the exact spot where that superheated gas is spilling into the Milky Way. Acting like a gargantuan exhaust vent, the newly discovered feature is a bright region of X-ray energy that’s nearly […]

Could nearby stars have habitable exoplanets? NASA’s Chandra X-ray Observatory hopes to find out
The search for life beyond Earth dutifully continues. Astronomers using NASA’s Chandra X-ray Observatory, as well as the European Space Agency‘s XMM-Newton, are contributing some new research to the hunt — and hoping to lay the groundwork for future projects. The researchers are using Chandra to study radiation emitted from nearby stars to establish whether or […]
NASA’s Chandra X-ray telescope captures closest super star cluster to Earth (image)
It’s a bird… it’s a plane… it’s a super star cluster! NASA’s Chandra X-ray telescope has imaged a star cluster that is “super” in every way. Westerlund 1 is super-large, super-massive, super-young, super-close — and it is creating stars at a super-fast rate. Westerlund 1 is located around 13,000 light-years away from Earth — meaning […]
How a jammed door is locking astronomers out of the X-ray universe
A gif showing a yellow-wrapped spacecraft with solar-panel wings in space. Just outside Hiroya Yamaguchi’s office is a blackboard crowded with exploded stars, spaceship schematics and spectral lines. The A4 printouts obscure almost all the free space, except for a tiny corner where he sometimes scribbles in white chalk. Right now, Yamaguchi, an associate professor […]
I’m an astrophysicist mapping the universe with data from the Chandra X-ray Observatory − clear, sharp photos help me study energetic black holes
When a star is born or dies, or when any other very energetic phenomenon occurs in the universe, it emits X-rays, which are high-energy light particles that aren’t visible to the naked eye. These X-rays are the same kind that doctors use to take pictures of broken bones inside the body. But instead of looking […]
X-ray spacecraft reveals odd ‘Cloverleaf’ radio circle in new light (image)
XMM-Newton, a European Space Agency and NASA-operated space telescope, has imaged a vast cosmic “Cloverleaf” to uncover its mysterious origins. The Cloverleaf is an example of an “odd radio circle,” or ORC. These objects are strange bubbles of radio light that are so huge they can be thousands of times the width of the Milky […]
How the XRISM spacecraft can study the X-ray universe with only 36 pixels
A new X-ray space telescope is broadening our understanding of the universe with just three dozen pixels — really putting smartphones with as many as 12 million to 48 million pixels to shame! The Japan Aerospace Exploration Agency (JAXA) and NASA spacecraft known as the X-ray Imaging and Spectroscopy Mission (XRISM; pronounced “crism”) launched in […]
Einstein Probe X-ray telescope releases 1st images taken with ‘lobster vision’
A joint Chinese and European X-ray telescope mission called Einstein Probe is successfully viewing the universe in widescreen, with a telescope design that mimics the eyes of lobsters. Einstein Probe, which launched on Jan. 9 aboard a Chinese Long March rocket, is currently undergoing testing and calibration of its instruments as it orbits the Earth […]
The Chandra X-ray spacecraft may soon go dark, threatening a great deal of astronomy
Last week, an ominous letter was published to the Chandra X-ray Observatory’s website. “Dear Chandra community,” it starts, “As many of you are aware, the NASA budget for FY25 and beyond was released…” This letter was written by Patrick Slane, director of the Chandra X-ray Center. In it, he’s talking about NASA’s budget proposal for […]

Major X-ray sky survey could relieve crisis surrounding the universe’s ‘lumpiness’
A new analysis of how galaxy clusters evolved over the 13.8-billion-year history of the cosmos could help solve a long-standing tension surrounding the ‘lumpiness’ of our universe’s matter content. Down the line, it may also help scientists solve a host of other cosmic mysteries. The first data from the eROSITA all-sky survey of cosmic X-ray […]
