Primordial holes could be hiding in planets, asteroids and here on Earth
Small primordial black holes (PBHs) are one of the hot topics in astronomy and cosmology today. These hypothetical black holes are believed to have formed soon after the Big Bang, resulting from pockets of subatomic matter ...

Discovery of most distant rotating disk galaxy challenges current formation theories
Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disk galaxy seems as orderly as present-day galaxies, but we see it as it was when the universe was only 700 million ...

Astronomers investigate the nature of a fast-spinning intermediate polar
Using various X-ray space observatories, astronomers from Columbia University in New York and elsewhere have investigated CTCV J2056–3014—an intermediate polar containing one of the fastest-spinning white dwarfs. Results ...
Astronomers detect multiple extended tidal tails in an old globular cluster
By analyzing the data from various astronomical surveys, astronomers have investigated an old globular cluster known as NGC 288. As a result, they detected multiple extended tidal tails associated with this cluster. The finding ...
Large radio bubble detected in galaxy NGC 4217
An international team of astronomers has performed radio observations of a star-forming galaxy known as NGC 4217. The observational campaign detected a large radio bubble in the galaxy's halo. The finding was reported in ...
The sun unleashes its strongest flare this cycle
Yesterday the sun released a huge solar flare, and it's heading toward Earth. It's nothing to worry about since it's nowhere near as large as the Carrington Event of 1859, but it is large enough to give us some amazing aurora.

Gravitational lens confirms the Hubble tension
We've known the universe is expanding for a long time. The first solid paper demonstrating cosmic expansion was published by Edwin Hubble in 1929, based on observations made by Vesto Slipher, Milton Humason, and Henrietta ...

Traces of antimatter in cosmic rays reopen the search for 'WIMPs' as dark matter
One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know ...

There were more black holes in the early universe than we thought, research finds
Supermassive black holes are some of the most impressive (and scary) objects in the universe—with masses around 1 billion times more than that of the sun. And we know they've been around for a long time.
