A tight clump of four star clusters sits in the Perseus galaxy cluster, and at first glance it looks like nothing special. No ...

When you gaze up at the night sky, you’re looking back in time. Light from the stars takes years, sometimes millennia, to ...

Using data from the Hubble Space Telescope, ESA’s Euclid space observatory, and Hawaii’s Subaru Telescope, the researchers discovered faint light emitting around the clusters. That light was clear ...

Astronomers have discovered a nearly invisible galaxy called CDG-2, which blends into the cosmic background and is made up of 99% dark matter. Unlike bright galaxies like the Milky Way, CDG-2 barely ...

A team of astronomers has identified an extremely faint galaxy called CDG-2, located roughly 300 million light-years from Earth, where an estimated 99% of its total mass is made of invisible dark ...

A newly discovered galaxy with glowing star-filled "tentacles" is rewriting parts of cosmic history.

A newly discovered jellyfish galaxy, seen as it existed 8.5 billion years ago, is challenging assumptions about conditions in the early universe. Astrophysicists at the University of Waterloo have ide ...

A dazzling new image produced using both the James Webb Space Telescope and the Hubble Space Telescope has revealed one of the most detailed views of the universe to date, NASA has announced. Created ...

Only one billion years after the Big Bang, clusters of galaxies were already forming. This discovery pushes back the age of the youngest known galaxy cluster by a third, and shows that the largest ...
