Experts from NASA and other international organizations recently simulated their response to a hypothetical asteroid impact scenario. The test was deemed a success. However, several media outlets have misreported the group's findings.

The Gaia space telescope has spotted the dim companions of eight bright stars, suggesting we can expect new glimpses of distant planets.

Astronomers using the James Webb Space Telescope have observed five extremely dense proto-globular clusters along a hair-thin arc of glittering stars. The discovery could help them understand how the earliest galaxies formed.

Saturn pumps into space varying amounts of heat based on its seasons, which drives planet-wide storms, data from NASA's Cassini mission has revealed.

The sparkling galaxy NGC 1546 stars in Hubble's first new image since changing to its new "one-gyro mode," ending the telescope's roughly month-long break.

Astronomer Giovanni Cassini observed Jupiter's 'Permanent Spot' in 1665, but new research suggests it's a different vortex from today's Great Red Spot.

The James Webb telescope has spotted a peculiar group of baby stars firing enormous jets into space at nearly the exact same angle. The discovery could hold new insights into how stars are born.

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

The "Blaze Star" T Coronae Borealis is expected to erupt with a magnificent explosion sometime between now and September, becoming visible to the naked eye. Here's how to find it when it does.

The time of the annual summer solstice will be the earliest it's been for centuries and will continue to creep forward every leap year until 2100. But why?
