Group Captain Shubhanshu Shukla has become only the second Indian to travel to space.
Interstellar comet 3I/ATLAS transforms into a giant 'cosmic rainbow' in trippy new telescope image
New photos, including a striking technicolor timelapse, show off the newly discovered interstellar object 3I/ATLAS as it shoots toward us through the solar system.
Giant meteor impact may have triggered massive Grand Canyon landslide 56,000 years ago
Researchers have found a link between two geological events in iconic locations of the U.S. Southwest that scientists previously didn't think had anything to do with each other.
Astronomers discover monster exoplanet hiding in 'stellar fog' around young star
A monster exoplanet as big as 10 times the size of Jupiter has emerged from the stellar gas and dust surrounding a young star, thanks to the telescope tag team...
Earth's magnetic field is weakening — magnetic crystals from lost civilizations could hold the key to understanding why
Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic...
In a cosmic first, astronomers spot a new planet system being born around an alien star
Astronomers spotted a baby star displaying the very first signs of planet formation in the zone surrounding it, similar to how our own solar system was born.
James Webb telescope reveals 'Sleeping Beauty' galaxies in the early universe — snoozing where they weren't supposed to exist
Using data from the James Webb Space Telescope, astronomers have discovered dormant galaxies with a wide range of masses in the first billion years after the Big Bang, moving one...
'Fighting dragons' light up little-known constellation in the Southern sky: Space photo of the week
A nebula where young stars sculpt dragon-like forms has been imaged in colorful detail by the Dark Energy Camera in Chile.
Earth may have at least 6 'minimoons' at any given time. Where do they come from?
Half a dozen fragments of the moon may briefly orbit Earth at any given time, before moving on to circle the sun, new research suggests.
If aliens existed on Mars 3.7 billion years ago, they would have needed umbrellas
A vast network of inverted channels, formed of sediment laid by ancient rivers, implies Mars was once a much rainier place than we thought.
NASA tests scalable satellite tech to launch sensors more quickly
NASA's Athena Economical Payload Integration Cost mission, or Athena EPIC, is a test launch for an innovative, scalable space vehicle design to support future missions. The small satellite platform is...
Hidden neighbor: Astronomers confirm long-suspected companion star near Betelgeuse
Betelgeuse is one of the brightest stars in the night sky, and the closest red supergiant to Earth. It has an enormous volume, spanning a radius around 700 times that...
