Astronomers have discovered oxygen and heavy elements in the earliest galaxy ever seen, suggesting some galaxies as early as 300 million years after the Big Bang matured early.

New research suggests that life could have the time and energy to arise on Earth-like worlds in the rapidly shrinking "Goldilocks zones" around white dwarf stars.

Using the now-retired Kepler space telescope, astronomers have discovered that larger planets grow up in more turbulent homes than smaller worlds.

The Euclid space telescope has dropped its first data and deep field observations showing millions of galaxies in great detail as it hunts for dark matter and dark energy clues.

The clearest and most precise images yet of the universe’s infancy from the Atacama Cosmology Telescope show the first steps toward the first stars and galaxies.

The James Webb Space Telescope is investigating the Flame Nebula, hunting for "failed stars" to better understand how brown dwarfs form and evolve.

The moon will turn blood red overnight on Thursday and Friday during the 'Blood Moon' total lunar eclipse. How can you tell what images of this event are the real deal?

The James Webb Space Telescope has found perhaps its most profound discovery to date. The uncovered preferred direction for galaxies supports the idea that the universe was born in a black hole.

Astronomers have traced a starnge blast of radiowaves that repeats every 2 hours back to a dead star white dwarf magnetically slamming its stellar companion.

Astronomers have discovered the smallest dwarf galaxy ever seen. It is a mystery how the satellite galaxy of Andromeda survived the blistering conditions of the early universe.

Strange events at the heart of the Milky Way could point toward a new dark suspect that annihilates to influence the chemistry of the cosmos.

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

Mysterious planetary mass objects that wander the cosmos alone could be created when young star systems clash. They aren't planets or stars, but are in a cosmic class of their own.

A hidden monster black hole in the Large Magellanic Cloud fired runaway stars at the Milky Way at millions of miles per hour.

The X-37B Orbital Test Vehicle-7 U.S. Space Force’s dynamic unmanned space plane has successfully returned to Earth after a novel aerobraking maneuver during its 7th flight.

NASA engineers are turning off two instruments on Voyager 1 and Voyager 2 to ensure these twin spacecraft can continue exploring interstellar space.

An X-ray signal that has puzzled scientists for 45 years was the "death knell" of a planet ripped apart by a white dwarf star, data from NASA's Chandra observatory has revealed.

The solar system could be packed with 1 million alien visitors, space rocks shaken away from our cosmic neighbor Alpha Centauri, new research has revealed.

Astronomers have used the James Webb Space Telescope to investigate the atmosphere of a cosmic body that is either a "failed star" brown dwarf or a rogue planet.

Scientists have used the wobble of the Milky Way and what are known as "cosmic lighthouses" to shine a light on the mystery of dark matter.

Astronomers have discovered that billions of comets in an icy shell around the solar system called the Oort Cloud mimic the spiral structure of the Milky Way.

The James Webb Space Telescope has joined the hunt for dark matter, aiding cosmic detectives in searching for signals indicating axion decay.

Astronomers were surprised to see the behavior of ultrafaint dwarf galaxies located in the Hydra cluster.
