For decades, scientists have debated the source of unusual star movements in Omega Centauri, the Milky Way's largest star cluster. Recent research, incorporating new pulsar data, provides clarity, suggesting that a cluster of stellar-mass…

Astronomers have used JWST to weigh a galaxy in the early Universe, finding that it has roughly the same mass as the Milky Way should have had at the same time in the Universe's history. The galaxy was seen in a gravitational lens and…

Explore Firefly Sparkle, an ancient galaxy revealed by the JWST, offering insights into the Milky Way's early formation and cosmic evolution.

We know that interstellar objects occasionally visit our solar system. So far, we have only discovered two interstellar objects (ISOs), but that's mainly because we can only distinguish them from solar system bodies by their orbital motion…

The Firefly Sparkle galaxy is so named because it resembles a "sparkle" or swarm of lightning bugs on a warm summer night.

Researchers said the galaxy, still in the process of assembling, dates to when the universe was roughly 5% of its current age

Our best glimpse yet at early star formation.

Nasa’s James Webb Space Telescope has detected and ‘weighed’ a galaxy that existed about 600 million years after the big bang.

Interstellar objects visit our solar system all the time. A new study shows they likely come in streams of sibling objects from the same star system.

For the first time, the NASA/ESA/CSA James Webb Space Telescope has detected and "weighed" a galaxy that not only existed about 600 million years after the Big Bang, but also has a mass that is similar to what our Milky Way galaxy's mass…

"The hunt for elusive intermediate-mass black holes continues," researcher Justin Read said.

Sometimes in astronomy, a simple question has a difficult answer. One such question is this: what is the mass of our galaxy?

A survey of high velocity clouds in the galactic halo of the Milky Way finds that they make up less of our galaxy's mass than we had previously thought.

Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be resolved?

A new video from the International Space Station shows SpaceX's Crew Dragon alongside the Milky Way, as the bright sun rises on the spacecraft's face.
