These observations could hint at how the cosmic titans grow to hold the immense masses we calculate.

Feeding supermassive black holes, hosting objects that power quasars blasting out the most powerful light in the universe, could hide in galaxies behind thick clouds of dust.

A coalition of over 50 astronomers is calling to rename the Large and Small Magellanic Clouds.

I use moon and Mars rocks in my teaching and have a modest collection of meteorites. I marvel at the fact that I can hold in my hand something that is billions of years old from billions of miles away.

Binary black holes are believed to inevitably spiral together, but dark energy and the expanding universe could help them maintain a safe distance and mimic a single black hole.

What astronomers can measure using telescopes is not what we really want to know – instead, we calculate the properties we're interested in studying by observing and interpreting apparent properties from afar.

When complete, the Square Kilometer Array Observatory (SKAO) will be the world's most powerful radio telescope — if SpaceX's Starlink satellites don't ruin its view.

A long-dead white dwarf star is running away from Hyades star cluster — and it could help astronomers solve a number of cosmic mysteries.

AI is the way forward in the search for extraterrestrial intelligence, from detecting radio signals to finding technosignatures on planets.
