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.
A surprisingly youthful estimate of the age of the rings has stirred a backlash.
