Nineteen gamma-ray bursts in one patch of sky point to a galaxy wall billions of light-years long
The ESA's Euclid space telescope took 26 hours to capture this portrait of the Milky Way's central bulge. This isn't part of its primary mission; instead it's kind of like bonus sc...
This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensive...
A bizarre "bow-and-arrow" radio galaxy nearly 1.8 million light-years across could reveal how galaxy clusters sculpt some of the universe's largest structures.
A five year survey by the South Pole Telescope has produced a catalogue of more than seven thousand galaxy clusters, some dating back nearly eight billion years, giving astronomers...
The NASA/ESA Hubble Space Telescope is still going strong and delivering unbelievably beautiful deep-space images. The latest Hubble image shows globular cluster NGC 6723, sometime...
Astronomers have discovered a galaxy so unlike anything in the textbooks that the researcher who found it, after 25 years studying these objects, says he has never seen its equal....
The Dark Energy Camera (DECam) has a massive 570 megapixel camera, and its new image is of the Corona Australis Molecular Cloud. Corona Australis is one of the closest star-forming...
Homer Dávila Gutierrez, director of SKYCR.ORG, has identified a gravitational arc candidate in the galaxy cluster MACS J0308.9+2645 from public data from the James Webb Space Teles...
The subject of today's NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thous...
Learn about the Big Ring, a superstructure of galaxies located 9.2 billion light-years from Earth that may challenge the standard model of the universe.
A supermassive black hole is also coming together at the heart of this galaxy maelstrom.
In new images from NASA's James Webb Space Telescope to celebrate its fourth science anniversary, a familiar galaxy transforms into something far richer and far more complex than e...
Observations of a distant cluster of stars in our galaxy have resulted in a new class of objects that turn out to be galactic building blocks. Researchers used Hubble Space Telesc...
Researchers have obtained the deepest images ever taken of IC 1101, allowing them to identify the galaxy's outer edge for the first time. The observations confirm it as the largest...
The Vera C. Rubin Observatory has released a stunning image of the COSMOS field. This image contains over half a million galaxies and fifty thousand stars. Astronomers have studied...
This brilliant new image, taken by Europe’s Euclid space telescope, offers a preview of the kind of imaging that will be possible with NASA’s upcoming Roman telescope
A team of researchers used the world's largest single-dish telescope and an interferometer to uncover previously hidden structures within the Orion Nebula. The project produced the...
"It's part of the fabric of astronomy research now."
Observing our celestial neighbor (and something much farther away).
The eROSITA telescope has released its second great catalogue of the X-ray sky with close to two million sources across half the sky, roughly double what it published before. Burie...
For its first billion years the universe was lost in fog, a thick haze of hydrogen that swallowed light whole. Something burned it away, and astronomers have long wondered what. No...
Scale in the universe is hard to understand from a purely human perspective. Many times the math just doesn’t sit well with our brains that evolved to capture and process data abou...
In this July 6, 2026, image, NASA's James Webb Space Telescope's Mid-Infrared Instrument (MIRI) reveals the nearby galaxy Centaurus A, exposing the dusty structures and hidden acti...
