Astronomers say they have solved an outstanding problem that challenged our understanding of how the universe evolved—the spatial distribution of faint satellite galaxies orbiting the Milky Way. These satellite galaxies…
Artemis 2 is scheduled to launch in 2024, but it may be tough for NASA to hit that target. Orion's successful splashdown Sunday afternoon (Dec. 11) returned some critical components…
Two new studies suggest that certain tetrahedral arrangements of galaxies outnumber their mirror images, potentially reflecting details of the universe’s birth. But confirmation is needed. Physicists believe they have detected…
Why haven't we found wormholes? It might be because they look just like blackholes! A group of researchers at Sofia University has found evidence that suggests the reason that a…
Is this isn't a worry, I don't know what is! Astronomers have discovered a giant asteroid hiding in the glare of the sun that might one day cross paths with…
An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The finding challenges Newton's laws of gravity, the researchers write in their publication. Instead, the…
Six months have passed since a European rocket lofted the James Webb Space Telescope into orbit. Since that time, the ultra-complex telescope has successfully unfolded its expansive sunshield, commissioned its…
A unique telescope that focuses light with a slowly spinning bowl of liquid mercury instead of a solid mirror has opened its eye to the skies above India. Such telescopes…
The launch of NASA’s Psyche asteroid mission, which was set for Aug. 1 on a SpaceX Falcon Heavy rocket, has been delayed to no earlier than Sept. 20 after ground…
Three years ago, the first ever image of a black hole stunned the world. A black pit of nothingness enclosed by a fiery ring of light. That iconic image of…
Physicists have proved that a subatomic particle can switch into its antiparticle alter-ego and back again, in a new discovery revealed today. The extraordinarily precise measurement was made by UK…
