New research offers the most precise measurements yet of pulsating Cepheid stars, which may hold clues about the immense size and scale of our universe.

The Gum 3 nebula, which resembles a swimming koi fish, is captured in a stunning new photo from the European Southern Observatory's VLT Survey Telescope.

The James Webb Space Telescope has found three of the universe's earliest galaxies, and they could reveal a lot about galactic dynamics. Here's how.

Starting in late 2025, the Vera C. Rubin observatory will image the outskirts of our galaxy in search of dark matter clues.

Dark energy has humans stumped. The force is sometimes even labeled "the worst prediction in the history of physics." Can AI do any better?

Space mysteries Imagine a future where the universe, all too soon, tears itself apart. Eventually, space-time is torn asunder, rendering the universe uninhabitable.

NASA's UltraViolet EXplorer (UVEX) spacecraft will launch in 2030 to conduct an all-sky survey in ultraviolet light to bring new understanding of how stars and galaxies evolve.

The James Webb Space Telescope could target tiny and bright galaxies in the early universe to unveil some secrets about the universe's most mysterious stuff, dark matter.

The motions of satellites in galaxy groups tell us that such groupings, and therefore possibly the universe, are younger than what standard cosmology tells us.
