A group of comets with unexplained movements presents a quandary

Thanks to the Hubble Space Telescope, we now know that a day on Uranus lasts for 28 seconds longer than previously thought - a difference that could be crucial in planning future missions to the gas giant

Bees exhibit remarkable aeronautical abilities, such as navigation, hovering, and pollination, that artificial flying robots of similar scale fail to do, explained Liwei Lin, distinguished professor of...

It could rip particles right out of empty space.

A new study characterizes a puzzling, highly energetic cosmic explosion, revealing a peculiar transient. Is Einstein Probe transient EP240408a a tidal disruption event, a gamma-ray burst, or something new?

MIT astronomers pinned down the origins of at least one fast radio burst, a brief and brilliant explosion of radio waves emitted by an extremely compact object. The team's novel technique might also reveal the sources of other FRBs.

Astronomers have finally pinpointed the source of slowly repeating radio bursts: a red dwarf star with a possible white dwarf binary companion. The post Odd, slowly repeating radio bursts traced to red dwarf star first appeared on EarthSky.

A shockwave caused by the galaxy NGC 7318b slamming into four other galaxies is akin to a "sonic boom from a jet fighter." Astronomers hope the event will reveal vital secrets about the often-violent evolution of our universe.

In 1974 we beamed a radio transmission into space that changed the way we think about our place in the cosmos

For less than $400, it's possible to observe places like the star-forming regions at the center of our galaxy.

A new study of grain samples from asteroid Ryugu shows that an ancient magnetic field helped form asteroids and planets in the early outer solar system. The post Ancient outer solar system had a weak magnetic field first appeared on EarthSky.

"Highlights the need for responsible space operations."

Commonly seen in Star Wars, the movie-inspired tractor beam came into life when a group of scientists used it to control the movement of tiny particles.

A chip-based "tractor beam" can trap and manipulate biological particles using a tightly focused beam of light emitted from a silicon-photonics chip. The device could help biologists and clinicians study DNA, classify cells, and investigate the mechanisms of disease.

Asteroid Ryugu possibly did not travel as far from its place of origin to its current near-Earth orbit as previously assumed. New research published in the journal Science Advances suggests that Ryugu was formed near Jupiter.

A new study reveals that Generation 2 Starlink satellites are leaking up to 30 times more radio waves than their predecessors. If SpaceX continues to deploy the newer versions as planned, we could reach an "inflection point" where astronomers can no longer properly study the cosmos, researchers warn.

Long-sought evidence of alien life could lurk in Earth's oceans, or in 'weird' objects orbiting near our planet, Harvard astrophysicist Avi Loeb says. Here is his plan to find it.

Nestled between mountains in a secluded corner of West Virginia, a giant awakens: the Green Bank Telescope begins its nightly vigil, scanning the cosmos for secrets.

Magnetars could zap clouds of atomic hydrogen, producing focused microwave beams.
