NASA's Perseverance Mars rover has captured photos of a big sunspot, which should rotate into view for those of us on Earth in the coming days.
Satellites watched weakening tropical storm Hilary bring a deluge to California hours after a series of earthquakes shook the Los Angeles region.
The James Webb Space Telescope strikes again, this time with a beautiful new view of a famous planetary nebula. But don't be fooled — none of this has anything to do with planets.
Scientists developing more sensitive next-generation gravitational wave detectors struggle with technical challenges that might be easily overcome by putting such detectors on the moon.
For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum.
Astronomer Carl Sagan once said that humanity is "made of star stuff." In a new video, astrophysicist Suzanna Randall explains what that actually means and where the elements in our body come from.
An experimental detector can now rule out dark matter particles down to about a fifth of a proton's mass.
Scientists were able to visualize the upper 1,000 feet of the moon's surface for the first time. Their results reveal billions of years of previously hidden lunar history.
Researchers have discovered a pattern where diamonds spew from deep beneath Earth's surface in huge, explosive volcanic eruptions.
Researchers flew NASA's ER-2 aircraft as close to thunderclouds as safely possible and captured 'the most detailed' data of gamma-rays and thunderclouds ever recorded through airborne analysis.
Last year Earth had more than 100 close encounters with large asteroids. What are the odds of a direct hit in the near future?
Sizzling ocean temperatures in the east-central tropical Pacific throughout July indicate there is a good chance El Niño conditions will remain strong for the next six months.
A new image released by NASA shows-off the galaxies of Abell 3322.
By modeling the neutrinos from a supernova as an exotic kind of fluid moving at nearly the speed of light, researchers are searching for signs of how neutrinos can interact with each other.
Satellites watched as an innocent-looking tropical depression exploded into the powerful Hurricane Hilary in just two days off the Pacific Coast of Central America.
ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA) snapped a new photo of the globular cluster NGC 6723 containing hundreds of thousands of gravitationally-bound stars.
Methane emissions from tropical wetlands have been soaring since 2006 and accelerating at the same breakneck speed as they have when Earth's climate flipped from a glacial to an interglacial period.
The way in which supermassive black holes grew to tremendous sizes in the early universe has been a mystery for astronomers, but the puzzle could soon be solved.
