An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.
Astronomers have discovered the first dormant black hole outside of the Milky Way. These black holes are not absorbing matter from a nearby star, making them incredibly hard to find.
NASA released five new images from the James Webb Space Telescope, revealing incredible details of ancient galaxies, stars and the presence of water in the atmosphere of a distant planet.
It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.
Astronomers studying fast radio bursts recently discovered one that repeats, has a persistent radio signal and originated in a galaxy much closer than it should have.
Sagittarius A* is a massive black hole at the center of the Milky Way. Now that astronomers have imaged it, they can begin to learn more about black holes within other galaxies across the universe.
The astronomy and astrophysics decadal survey for the 2020s lays out plans to search for life on distant planets, understand the formation of galaxies and solve deep mysteries of physics.
Hypervelocity stars were discovered only 15 years ago and are the closest things in existence to real shooting stars. They travel at millions of miles per hour, so fast that they can escape from galaxies.
Such a mission could be developed soon, allowing astrophysicists to take selfies of the solar system and use the Sun’s gravity as a lens to peer deep into space.
The largest orbital telescope ever made will allow astronomers to study the atmospheres of alien planets, learn about how stars form in the Milky Way and peer into the farthest reaches of the universe.
The universe has a finite age — 13.8 billion years to be exact. So if it had a beginning, why is it so difficult to say for sure whether it will have an end?
