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.

Webb telescope detects unusual gas jets from Centaur 29P
Inspired by the half-human, half-horse creatures that are part of Ancient Greek mythology, the field of astronomy has its own kind of centaurs: distant objects orbiting the sun between Jupiter and Neptune. NASA's James Webb ...

Influence of a black hole's spin: First evidence of precession in ultraluminous accretion disks
Gas swirls around a black hole due to its intense gravity, forming an accretion disk. These accretion disks, being among the most efficient energy conversion mechanisms in the universe, emit light and plasma jets. When a ...

Dark matter could have slight interaction with regular matter, study suggests
The reason we call dark matter dark isn't that it's some shadowy material. It's because dark matter doesn't interact with light. The difference is subtle, but important. Regular matter can be dark because it absorbs light. ...
