How did this 20-light-year-wide 'Diamond Ring' form in space? Maybe a cosmic bubble burst
November 24, 2025
A distant, mysterious glowing ring of gas and dust has finally given up its secrets — and it turns out to be less of a romantic cosmic jewel than its shimmering appearance suggests.
In the constellation Cygnus, a bright knot of stars seems to adorn one edge of a nearly…
Earth just got hit by a stealth solar storm no one saw coming
November 24, 2025
A stealth solar storm hit Earth on Nov. 20. It arrived without warning and may have contributed to auroras visible at mid latitudes.
This event didn’t trigger a geomagnetic storm; however, such solar storms, or coronal mass ejections (CMEs), are still exciting because…
James Webb Space Telescope spots a gassy baby galaxy throwing a tantrum in the early universe
November 24, 2025
A baby galaxy is throwing one heck of a tantrum, and it’s shaking up our understanding of the earliest galaxies.
Recently, an international team of astronomers used the James Webb Space Telescope (JWST) to uncover a bright, young galaxy in the early universe. Although it’s not the earliest galaxy ever found, it is among the first generation of large galaxies to appear after the Big…
Comet C/2025 K1 (ATLAS) breaks apart in incredible telescope photos
November 20, 2025
A comet discovered earlier this year continues to break apart after its close brush with the sun this month.
Astronomer Gianluca Masi of the Virtual Telescope Project captured breathtaking imagery of solar system comet C/2025 K1 (ATLAS) as its central icy core, or nucleus…

A history-making robotic rescue mission scheduled to launch next year will fly on a rocket dropped from a plane.
In September, NASA announced that it has chosen Arizona company Katalyst Space Technologies to boost the altitude of its Neil Gehrels Swift Observatory, a space…
The headline says it all: The list of our moon’s craters just got a little longer.
On Nov. 13, the Lunar Reconnaissance Orbiter Camera (LROC) team — which operates visual equipment on NASA’s Lunar Reconnaissance Orbiter (LRO) — announced the discovery of a never-before-seen dent in Earth’s natural satellite. It appears to be about 72 feet (22 meters) in diameter, probably…
Astronomers have discovered that an aging red giant star has a closely orbiting stellar companion, which could be causing havoc to the star’s processes. The discovery could help researchers better understand what will happen to Earth and the other solar system planets…
Flagship European space science missions conducted in collaboration with NASA face a possible combined funding shortfall of nearly $2 billion due to budget cuts put forward by the administration of U.S. President Donald Trump. The European Space Agency hopes its member…
As our black hole images get more detailed, we may find Einstein wasn't quite right about them
November 19, 2025
New research suggests future images of black holes could be precise enough to allow scientists to determine if these objects are accurately described by Albert Einstein’s theory of gravity, general relativity — or if they are best modeled by alternative theories.
Such black hole research is possible due to breakthroughs in black hole imaging pioneered by the Event Horizon Telescope (EHT)…
