IC 1101 holds the title of the largest galaxy known to humanity, and its colossal size is almost beyond comprehension.

Astronomers have turned the Atacama Large Millimeter/submillimeter Array (ALMA) into a time machine to peer back in cosmic ...

There could be many more satellite galaxies orbiting the Milky Way than previously thought or observed, according to ...

For centuries, we’ve looked up at the stars and wondered if the universe is infinite. We know there is a visible boundary of what we can observe, defined by how far light has traveled since the Big ...

Yale astronomer Pieter van Dokkum and a team of researchers have discovered an object in space they call the "Infinity" ...

According to a provocative new study, that might just be our cosmic address. This idea is meant to solve one of the biggest puzzles in cosmology: the Hubble tension. This long-standing discrepancy ...

CRISTAL, an ALMA Large Program, observed 39 typical star-forming galaxies selected to represent the main population of galaxies in the early universe.

Astronomers have discovered a galaxy that has been "frozen in time" for billions of years. Like a celestial dinosaur fossil, this galaxy could reveal the secrets of cosmic evolution.

Fresh evidence claims that the Earth and the surrounding galaxy are suspended inside a cosmic void based on echoes from the ...

If early galaxies functioned in the same way, Wold said, they would have generated enough light to reionize the hydrogen fog and make the universe transparent.

Because it doesn't interreact with light or electromagnetism, dark matter exists to us only through its influence on visible ...
