Space

Path of the solar system through the Local Interstellar Cloud. The cloud’s profile is preserved as an interstellar fingerprint in Antarctic ice.

A Rock the Size of Several City Blocks Will Pass Closer Than Your TV Satellite in 2029

Engineer Jaakko Karras inspects a next-generation Mars helicopter rotor blade prior to testing it at supersonic speeds in the 25-Foot Space Simulator at NASA’s Jet Propulsion Laboratory in November 2025.

Fifty-Six Million Years Frozen: New Model Rewrites the Story of Snowball Earth

Artist’s conception of this research showing an imagined time sequence as a star passes behind a TNO with an atmosphere.

Tiny World in Outer Solar System Has an Atmosphere. It Shouldn’t.

A new study of the interstellar comet 3I/ATLAS led by the University of Michigan shows that its water has a remarkably high content of deuterium. This form of hydrogen is comparatively less abundant in our solar system, enabling researchers to glean new insights about other planetary processes at work in our galaxy.

Interstellar Comet Carries Water Unlike Anything in Our Solar System

Jets of energetic particles streaming away from the black hole Cygnus X-1 (at left in this artist’s rendering) bend in the stellar wind from the supergiant star paired in orbit with the black hole. Researchers used the extent of the bending to produce the first measurement of the power of a black hole’s jets. IMAGE: ICRAR/CURTIN UNIVERSITY

Nearest Jupiter Has Water-Ice Clouds and Scientists Are Not Sure Why

The sample locations where Curiosity snagged three samples of drilled rock at this site on its way out of the Glen Torridon region. Analyzing these samples revealed diverse organic molecules on Mars.

Earth Fungus Might Survive a Trip to Mars

The strong stellar wind from the supergiant star pushes the jets launched by the black hole away from the star. This causes the jet direction to vary as the black hole and the supergiant star move around their orbit.

Black Hole That Dances in the Wind Finally Tells Us How Powerful Its Jets Really Are

The Ghostly Particles That May Have Built the Universe’s First Monster Black Holes

The same gentle wind that would create small ripples on a lake in Earth (right) would make large waves on Saturn’s largest moon Titan (left).

Stand on Titan’s Shore and Feel a Soft Breeze. Then Watch the Waves Come.
