"Dead stars" known as white dwarfs have already shown the potential to help us better understand how planetary systems, including our own solar system, take shape and evolve. Now, research from the University of Michigan ...
Positrons—the antimatter counterpart of electrons—are created in high-energy cosmic processes. When normal matter meets its antimatter counterpart, they annihilate, or vanish, and produce a distinctive 511 keV gamma-ray signal. ...
Black holes represent some of the most extreme environments in the universe. They are the sources of the strongest gravitational fields, allowing us to test Einstein's theory of general relativity to an extent impossible ...
Astronomers have discovered a remarkably tiny group of six young galaxies just 1.2 billion years after the Big Bang. This may be a rare glimpse of how some of the universe's largest galaxies formed. The paper outlining the ...
The Whirlpool galaxy (M51) is a classic grand spiral galaxy. It was the first object identified as a spiral, way back in 1845. At the time, it and other galaxies were considered spiral nebulae, since astronomers didn't know ...
Mysterious high-speed "bullets"—clumps of possibly oxygen-rich gas traveling at up to 20 million miles per hour—have been discovered shooting out of the rarest stellar explosion in our galaxy.
The star that formed the Jellyfish nebula may have had a partner star that exploded 100,000 years earlier, according to international researchers, who say that this may be the first known discovery of a binary star system ...
The Milky Way may have undergone a dramatic change in orientation during its history, according to new research that helps explain a long-standing mystery about our galaxy. Using supercomputer simulations of galaxies like ...
Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational interactions, Newton's theory of universal gravitation works just fine. Newton's model is good enough ...
A new study led by astronomers at The University of Texas at Austin proposes a theory that could solve two astronomical riddles at once: the nature of Little Red Dots and the origin of globular clusters. Rather than representing ...
