Data from the Gaia satellite is so precise, it might be able to detect cosmic gravitational waves.
If an alien civilization has a Starlink-like constellation of satellites, we might be able to find them.
If dark matter exists, it could make Jupiter-like exoplanets warmer than we expect.
If there are aliens out there, they probably aren’t in the central region of our galaxy.
A new study confirms the existence of dark energy with stunning accuracy.
A red giant star may have a black hole companion that is only three solar masses in size.
The evolution of cosmic expansion could be measured by a new method using intensity correlation speckles.
A study of rotating black holes show that some spin so quickly because dark matter particles haven’t slowed them down.
Binary black holes lens light so strongly it’s difficult to simulate how they would appear. A new simulation shows us how strange and complex it can get.
