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.

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 ...

Webb detects fast outflow in the host galaxy of a luminous quasar
An international team of astronomers has employed the James Webb Space Telescope (JWST) to perform spectroscopic observations of a luminous quasar known as J1007+2115. They detected a fast outflow originating from the quasar's ...
Observations explore the nature of transitional millisecond pulsar PSR J1023+0038
Using the Gran Telescopio Canarias (GTC), astronomers from Italy and Spain have carried out high-temporal-resolution optical spectroscopic observations of a transitional millisecond pulsar designated PSR J1023+0038. Results ...

Turbulent solar wind originates in the sun's corona, study shows
Solar wind is a never-ending stream of charged particles coming from the sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the sun's variable magnetic ...

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. ...

The universe is smoother than the standard model of cosmology suggests. So is the theory broken?
Given how unfathomably large the universe is, it is perhaps understandable that we haven't yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we could explain, that cosmologists ...
