The transforming exoplanet that was observed by the WIYN 3.5-meter telescope at the U.S. National Science Foundation Kitt ...

The James Webb Space Telescope (JWST) is allowing astronomers to examine distant galaxies in the far reaches of the early universe for the first time. Some of these have chemical signatures that seem ...

Over the course of billions of years, the Universe has steadily been evolving. Thanks to the expansion of the Universe, we are able to "see" back in time to watch that evolution, almost from the ...

Astronomers using the James Webb Space Telescope believe they have discovered Population III stars — the universe’s first generation of stars that formed shortly after the Big Bang — according to a ...

Astronomers have chased the first stars for decades, squinting at the early universe for any hint of their brief, brilliant lives. Now a tiny, lensed speck coined LAP1-B may be the clearest glimpse ...

We may have finally seen the first generation of stars. Astronomers have been looking for these primordial behemoths, called Population III stars, for decades. Now they have found what may be the most ...

In the distant past, the Solar System was rife with impacts and collisions. Millions of rocky objects zoomed chaotically through the system, smashing into each other in collisional cascades. Over time ...

Just two decades after astronomers discovered the first exoplanet, NASA has confirmed the existence of 6,000 alien worlds. The total will rise even quicker as next-generation telescopes take flight.

The highest energy neutrino ever detected from space may finally have an origin story. Mathematical analyses suggest that the ghost particle could’ve come from a theoretical object known as a ...
