Roger Penrose, Reinhard Genzel and Andrea Ghez were awarded the Nobel Prize in Physics for their studies of black holes.
Cosmologists have concluded that the universe doesn’t appear to clump as much as it should. Could both of cosmology’s big puzzles share a single fix?
Professional astronomers may not point their telescopes by hand anymore, but COVID-19 has still closed observatories and impeded research.
Astronomers are discovering that magnetic fields permeate much of the cosmos. If these fields date back to the Big Bang, they could solve a major cosmological mystery.
After a burst lit up their telescope “like a Christmas tree,” astronomers were able to finally track down the source of these cosmic oddities.
And why is the black hole at the center of our own galaxy so dim?
A problem confronts cosmology: Two independent measurements of the universe’s expansion give incompatible answers. Now a third method, advanced by an astronomy pioneer, appears to bridge the divide.
By watching for a special kind of flare, astronomers have identified the fingerprints of an Earth-size planet orbiting a distant star.
As astronomers get better at finding the comets and asteroids of other stars, they’ll learn more about the universe and our place in it.
