A distant galaxy nicknamed "Cosmic Grapes" is bursting with massive star-forming clumps — far more than expected — offering fresh clues about how galaxies grew in the early universe.

In a first, scientists have recreated the formation of the first ever molecules in the universe to learn more about early star formation.

A surprising new paper suggests that the universe's expected lifespan is just 33 billion years, and that the cosmos will start dying in less than a third of that time. However, this is only one possible theory.

Using the ALMA telescope, astronomers have revealed the internal structure of the first galaxies in the universe, hinting at how our cosmos took shape.

Astronomers claim to have found new evidence supporting a controversial observation that our galaxy is residing in an unusually sparse region in space. If it's correct, it could rewrite cosmology.

NASA's Chandra X-ray Observatory has captured a striking image of a distant quasar from the "cosmic noon," including a giant energy jet "being illuminated by the leftover glow from the Big Bang itself."

Astronomers have discovered a new class of bright, long-lasting cosmic explosions that offer a new probe into studying the universe's most distant black holes.

For the first time, astronomers have used a ground-based telescope to observe polarized microwave light from the universe's earliest epoch. Their observations could give them a better understanding of how the universe evolved.
