Scientists discovered that moons orbiting starless planets drifting through space could stay warm enough for life for billions of years. A thick hydrogen atmosphere might trap heat and support liquid water even in the darkest corners of our galaxy.
NASA's newest space telescope will discover more planets in five years than humanity has found in all of history combined. The Roman Space Telescope, launching in 2027, will also create the first real census of mysterious rogue planets drifting through space without stars.
Scientists discovered that moons orbiting rogue planets drifting through dark space could stay warm enough for liquid water for billions of years. Thick hydrogen atmospheres and internal heating might create perfect conditions for life in the universe's loneliest places.
Scientists discovered that moons orbiting lonely, star-less planets drifting through space might stay warm enough for liquid water for over 4 billion years. Thick hydrogen atmospheres and internal heating could make these seemingly desolate worlds surprisingly hospitable.
Astronomers discovered two pairs of Jupiter-sized planets floating through space without a star, strengthening evidence that these mysterious objects are real. The finding comes from a different region of the Milky Way than previous discoveries.
NASA's Hubble telescope discovered the largest planet-forming disk ever seen, stretching 400 billion miles across with bizarre one-sided structures that could rewrite our understanding of how planets are born. The massive disk contains enough material to create multiple giant planets.
The James Webb Space Telescope captured stunning images of two planet-forming disks, and one may contain a newborn planet clearing its path through cosmic dust. Scientists are watching planetary birth in real time, 480 light-years away.
Scientists have found the largest "super-puff" planets ever discovered, with densities lighter than cotton candy. These cosmic oddities are challenging what we know about how planets form. --- ##
Astronomers are finding new clues about a hidden giant planet beyond Neptune, and the mystery is getting more exciting. Fresh discoveries suggest Planet Nine could be real but lurking much farther away than anyone expected.
Scientists just confirmed the first atmosphere around an Earth-like planet in the habitable zone where liquid water could exist. The discovery makes planet LHS 1140b our best shot yet at finding life beyond our solar system.
Astronomers discovered the first atmosphere surrounding an Earth-like rocky planet in the habitable zone of a distant star, bringing us closer to finding life beyond our solar system. The planet, located 48 light-years away, marks a groundbreaking step in the search for worlds where life could exist.
NASA's Hubble Space Telescope just captured the largest planet-forming disk ever seen, and it's nothing like scientists expected. The enormous cosmic nursery could reshape our understanding of how planets are born.
NASA's James Webb Space Telescope just gave us a front-row seat to planet formation, capturing stunning images of two young stars surrounded by the cosmic dust and gas that will become new worlds. These images reveal exactly how planets grow from tiny particles into massive spheres orbiting distant suns.
Mercury joins Venus and Jupiter for a stunning five-night planet parade visible to the naked eye through Monday. No telescope needed for this cosmic show.
Award-winning photographer Josh Dury captured a rare six-planet parade stretching across nearly 180 degrees of sky from England's southern coast. The cosmic lineup, visible through February 28, includes Mercury, Venus, Jupiter, Saturn, Uranus, and Neptune in one breathtaking image.
A stunning planetary parade is lighting up evening skies this week, bringing six planets into view at once. With just an hour after sunset and a clear view of the horizon, stargazers can witness this rare cosmic alignment.
Early March offers a dazzling celestial treat as four bright planets shine together in the evening sky, with Mercury making its best appearance of 2025. Even better, no telescope needed.
Jupiter, Venus, and Mercury will create a stunning "planetary bridge" visible in the western sky on May 27, offering skywatchers a rare celestial show. You won't need fancy equipment to catch this mini parade of planets stretching between the constellations of Gemini and Taurus.
Astronomers discovered four "baby" planets caught in the act of transforming into the galaxy's most common type of world. The breakthrough solves a mystery about how super-Earths and sub-Neptunes take shape.
The James Webb Space Telescope found a supergiant planet that collected metal-rich materials as it formed, solving a cosmic mystery about how the universe's largest planets are born. This discovery could rewrite our understanding of planet formation.
