Supernovae are the Source of Dust in Early Galaxies
Dust is the building block for much of the Universe, including the planet you were born on. But where did…
Astronomers Map out the Radio Waves Coming From Large Satellite Constellations
You've heard that satellite constellations like Starlink are a problem for astronomers and their telescopes. Because the satellites are communicating…
Did the Pulsar Timing Array Actually Detect Colliding Primordial Black Holes?
With last week's announcement of the gravitational wave background detected by timing arrays, the assumption was that these are the…
The Early Universe Ran in Slow Motion
One of Einstein's predictions is that we should see time moving at different rates at different ages of the Universe.…
Gravitational Waves Can Be Gravitationally Lensed, and This Could Provide Another Way to Measure the Expansion of the Universe
Astronomers can never have enough ways to measure the expansion in the Universe, from nearby stars to distant quasars. A…
A Planet Was Swallowed by a Red Giant, But it Survived
When our Sun runs out of hydrogen fuel in its core, it'll switch to burning helium and bloat up as…
Astronomers Find the Fastest Spider Pulsar, Filling in the Missing Link in Their Evolution
Pulsars are rapidly spinning neutron stars which release blasts of radio waves with atomic clocklike accuracy. The fastest can be…
