Scientists may have finally spotted the universe's very first stars, born just 400 million years after the Big Bang. The James Webb Space Telescope detected these ancient giants in a tiny companion object near one of the early universe's brightest galaxies.
The James Webb Space Telescope has detected the strongest evidence yet for Population III stars, the first generation of stars that illuminated the dark universe. Two independent research teams confirmed the discovery using metal-free chemical signatures from a tiny object near one of the most distant galaxies ever observed.
A comet that hasn't visited Earth in 170,000 years is lighting up predawn skies right now, and Monday offers the best chance to spot it near a crescent moon. You only need binoculars and an early alarm.
NASA's James Webb Space Telescope discovered a unique "stingray" galaxy that finally explains one of astronomy's strangest puzzles. Scientists believe these mysterious cosmic objects aren't a new type of galaxy at all, but a brief evolutionary phase every galaxy goes through.
After Artemis II's historic Moon flyby, the first since 1972, six groundbreaking space missions are set to launch by 2026. From hunting for lunar water to discovering Earth-like planets, these missions promise to transform our understanding of the cosmos.
Thousands of space enthusiasts will gather in New York this weekend for the 35th annual Northeast Astronomy Forum, featuring NASA astronaut legends and hands-on stargazing experiences. The event brings together over 100 vendors and some of the most inspiring voices in space exploration.
Strange red lights in the young universe puzzled astronomers for years, but new research reveals they're young black holes wrapped in dense gas clouds, not impossibly massive galaxies. The discovery rewrites our understanding of how supermassive black holes grew in the early cosmos.
Three amateur astronomers in Queensland made history by becoming the first citizen scientists to discover a planetary ring, proving that world-changing discoveries can happen in your own backyard. Their finding helped solve a cosmic mystery that professional telescopes had missed.
A comet that last visited Earth during the Ice Age is putting on a brief show in pre-dawn skies through April 20. Stargazers have just days to catch this once-in-a-lifetime visitor before it disappears forever.
A rare comet could brighten enough for people to see with their naked eyes or binoculars this month, offering early risers an exciting celestial show. The comet reaches its brightest points between April 20 and 27.
A newly brightening comet could become visible to the naked eye in mid-April, offering early risers a rare celestial show. Comet PanSTARRS is expected to reach peak brightness around April 20 when it passes closest to the sun.
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.
NASA's Artemis II crew photographed the Milky Way galaxy during their historic moon flyby, echoing the famous Earthrise image from 1968. The four astronauts are now speeding home at 1,700 mph, with splashdown set for Friday in the Pacific Ocean.
Scientists are getting an unexpected second chance to build dream telescopes on the moon's far side, thanks to renewed lunar missions. A radio observatory there could reveal secrets from the universe's mysterious "dark ages."
NASA's Artemis II astronauts are heading home after becoming the first humans in over 50 years to see the moon's far side up close. Their mission opens the door to groundbreaking lunar science that could reveal secrets from the universe's earliest days.
University of Chicago undergrads discovered the most chemically pure star ever observed during a spring break research trip to Chile. The ancient star offers a rare window into how the universe's second generation of stars formed billions of years ago.
Four astronauts just completed humanity's first moon flyby in over 50 years, and their breathtaking photos are giving scientists new insights while reminding us all how incredible space exploration can be. The Artemis 2 crew spent Monday circling the far side of the moon, documenting features never before seen by human eyes in sunlight.
Four astronauts just returned humanity's first close-up moon photos in over 50 years, including a jaw-dropping view of a solar eclipse from space. The images from NASA's Artemis II mission show our cosmic neighbor like we've never seen it before.
NASA's Artemis II crew just shared breathtaking images from humanity's first Moon fly-by in over 50 years, including an "Earthset" and a 54-minute solar eclipse. These historic photos mark a giant leap forward in returning humans to deep space.
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.
