In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy ...
NASA’s Fermi Gamma-ray Space Telescope "detected none of the high-energy gamma-ray light" from a nearby supernova. NASA ...
Cosmic rays are made primarily of protons with a few electrons sprinkled in, and they can reach energies even higher than ...
NASA’s asteroid-hunting Psyche spacecraft recently needed a little gravitational assist from Mars to keep speeding towards ...
Faint, distant galaxies spotted by the James Webb Space Telescope are beginning to reshape how scientists understand the high ...
Scientists have taken a fresh look at the Milky Way's mysterious gamma-ray glow using machine learning and uncovered evidence ...
Astronomers have made a series of landmark observations of one of the universe's most violent events. Using the U.S. National Science Foundation Very Large Array (NSF VLA) radio telescope, which is ...
First radio detection of polarized light and Faraday rotation in a gamma-ray burst reveals how magnetic fields shape these ...
When massive stars die, they explode, leaving behind supernova remnants. Given how common binary star systems are — more than half the stars in our galaxy have a companion — it stands to reason that ...

I’m a Harvard astrophysicist. Here’s why the government asked me to lead a council on UFOs and national security
A month ago, I was visited by a representative from the Office of the Director of National Intelligence (ODNI). He raised a ...
New research has failed to rule out self-annihilating dark matter as the source of a gamma-ray emission radiating from the heart of the Milky Way.
The spacecraft aced its encounter with Mars. Now, mission scientists are studying a trove of data from the flyby in ...
