Universe
Stellar evolution, black holes, neutron stars, and high-energy phenomena — the physics of stars from birth in nebulae to death in supernovae.
In two separate papers published in Physical Review Letters, researchers investigated the nuclear reactions that take place inside supernovae and X-ray bursts—two of the universe's most powerful explo
Astronomers have discovered the first confirmed dual active galactic nucleus in a Green Pea galaxy, revealing two supermassive black holes growing at the same time inside a compact, intensely star-for
You may have heard the phrase "we are made of star-stuff." This statement by the astronomer Carl Sagan refers to the fact that elements heavier than hydrogen and helium were forged in the centers of t
Astronomers have linked an X-ray flash discovered by the Einstein Probe to a known type of supernova with unusual features that point to the birth of an ultra-dense, rapidly spinning magnetar. The pap
Astronomers at MIT and elsewhere have spotted an extremely bright red spot in the early universe. The object resembles an enormous star, roughly the size of our solar system. But it also is putting ou
Astronomers have witnessed a black hole violently shredding a massive star, creating one of the most energetic stellar explosions ever observed. The event, nicknamed “the Whippet,” briefly released ab
From launchpads to low Earth orbit and beyond, space companies and their affiliates are deploying a familiar marketing tactic—with a new twist. In a space economy projected to reach US$1.8 trillion by
Astronomers have released more than three million new spectra in a sweeping expansion that, for the first time, brings SDSS-V optical observations to the Southern Hemisphere. The data reveal everythin
Astronomers using the James Webb Space Telescope have discovered a bizarre object from just a few hundred million years after the Big Bang that looks like an enormous star but shines far too brightly
