For many years, the simplest view of dark energy has been that it remains unchanged. Throughout cosmic history, the mysterious ingredient believed to drive the universe's accelerated expansion is thought to have behaved in ...
Using data from the DESI Legacy Imaging Surveys, with help from artificial intelligence, an international team of scientists has discovered 70 new gravitational lenses—rare cosmic alignments that act as natural magnifying ...
An undergraduate astrophysics student at UC Berkeley has found three unusual galaxies—cataloged as Shapiro Dwarf Galaxies I, II and III. Each galaxy is far from other galaxies and has stopped making stars, a combination that ...
The universe may be trapped in its own comfort zone, and a researcher in the College of Engineering and Computer Science has helped explain why it cannot seem to leave. A new study suggests the universe could be locked into ...
Primordial black holes (PBHs) don't exist as far as we know. But if they did, these hypothetical objects would have formed in the early universe rather than from dying stars, and they may even make up dark matter. That's ...
Dark matter could be a type of matter in the universe that does not emit, absorb or reflect detectable light and appears to interact very weakly with regular matter. Although physicists have observed gravitational effects ...
In the early days of the universe, our home looked very different from how it does today. Back then, the region in our universe that would eventually become our Milky Way neighborhood was a collection of thousands of smaller ...
Astronomers analyzed 2,435 galaxies hosting actively feeding black holes using data from the Dark Energy Spectroscopic Instrument (DESI). Among them, they identified 546 "bulgeless" galaxies—systems with little or no central ...
An instrument built to study cosmic rays has turned out to be a powerful tool for investigating thunderstorms. Earlier observations with the GRAPES-3 muon telescope revealed that thunderclouds can develop electrical potential ...
Researchers have used some of the most detailed simulations yet of the early universe to investigate how the first stars and galaxies formed. Led by researchers at the University of Bath in the U.K., alongside collaborators ...
