A Cambridge-led study suggests comets rarely delivered useful quantities of life’s molecular ingredients to early Earth because impacts destroyed them and surviving material wouldn’t have stayed concentrated at the surface for long.
Baffling long radio echo delays have prompted a range of potential explanations, most of which focus on a variety of unexplained natural phenomena occurring in Earth’s atmosphere.

The European Space Agency’s Copernicus Sentinel-3 satellite mission captured a close-up of West Antarctica from its perch high above Earth.
A phenomenon rarer than a solar eclipse and more powerful than any single storm system is unfolding this fall, and NASA is tracking it closely. El Niño is a natural climate pattern that emerges roughly every two to seven years marked by warmer-than-normal water temperatures in parts of the equatorial Pacific. NASA scientists are keeping […]
The location of Earth’s geographic poles has changed several times over the past 320 million years in a process known as true polar wander.
The Etosha Pan in northern Namibia, the largest salt flat in the country, looks otherworldly in this satellite photo.
The Wildhorse grass fire in eastern Idaho erupted with a massive pulse of smoke. No one had expected it, but the wildfire had launched what’s known as a pyrocumulonimbus cloud, or pyroCb. It was an elusive weather phenomenon that scientists on NASA’s INSPYRE (INjected Smoke and PYRocumulonimbus Experiment) campaign spent weeks this summer hunting across […]
Like tendrils on a vine, lava spreads out from the northern crater of Krasheninnikov, a volcano pair on the Pacific coast of Russia’s Kamchatka Peninsula. On July 30, 2025, an 8.8-magnitude earthquake had struck in the nearby ocean, apparently jolting one of the two volcanoes awake. A few days later, for the first time in […]
