What did ancient humans know about astronomy?
Humanity's ability to track and monitor celestial cycles stretches back into prehistory, long before the invention of telescopes and astrolabes.
Supermassive black holes are messy eaters big on recycling
These observations could hint at how the cosmic titans grow to hold the immense masses we calculate.
Star-birthing galaxies can hide supermassive black holes behind walls of dust
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.
The Magellanic Clouds must be renamed, astronomers say
A coalition of over 50 astronomers is calling to rename the Large and Small Magellanic Clouds.
Space rocks and asteroid dust are pricey, but these aren’t the most expensive materials used in science
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.
Dark energy may allow black holes to live in 'perfect pair' binaries
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.
Astronomers have learned lots about the universe − but how do they study astronomical objects too distant to visit?
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.
Powerful new radio telescope could unmask the ancient universe — if satellites don't ruin the view
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.
