You Can Build a Home Radio Telescope to Detect Clouds of Hydrogen in the Milky Way
If I ask you to picture a radio telescope, you probably imagine a large dish pointing to the sky, or…
We Understand Rotating Black Holes Even Less Than We Thought
The theory of black holes has several mathematical oddities. Recent research shows our understanding of rotating black holes might not…
How Many Additional Exoplanets are in Known Systems?
NASA's TESS mission has turned up thousands of exoplanet candidates in almost as many different star systems. But if one…
Another Way to Extract Energy From Black Holes?
Black holes are incredible powerhouses, but they might generate even more energy thanks to an unusual effect known as frame…
Future Space Telescopes Could be Made From Thin Membranes, Unrolled in Space to Enormous Size
As we saw with JWST, it's difficult and expensive to launch large telescope apertures, relying on origami techniques to unfold…
Webb Confirms a Longstanding Galaxy Model
The spectra of distant galaxies shows that dying sun-like stars, not supernovae, enrich galaxies the most.
Will Advanced Civilizations Build Habitable Planets or Dyson Spheres
Freeman Dyson proposed that advanced civilizations might eventually harvest all the energy coming from their stars by surrounding them with…
Learning More About Supernovae Through Stardust
Dust grains older than the Sun can tell us about how supernovae enriched the cosmos with heavy elements, but the…
Astronomers Predict the Orbits of Potentially Hazardous Comets From Meteor Showers
Long-period comets can have orbits that can take hundreds of years before they return to the inner Solar System and…
Astronomers Have Found the Fastest Spinning Neutron Star
In 2005 astronomers found a pulsar rotating at 716 times a second. Now a team studying an X-ray binary has…
