As orbits become more crowded and littered with debris, the US operator is having to move its devices to dodge damage.

There’s little about building spacecraft that anyone would call simple. But there’s at least one element of designing a vehicle that will operate outside the Earth’s atmosphere th…

A 66 million-year-old mystery behind how our planet transformed from a tropical greenhouse to the ice-capped world of today has been unraveled by scientists. Their new study has revealed that Earth's massive drop in temperature after the dinosaurs went extinc…

A star 13 times the mass of the Sun just vanished. Here's what could be hiding in its place.

And then do a quick review the next morning.

"In our solar system, the most massive moon is Ganymede, which is still extremely small compared to what we are inferring here."

Once these were the largest and most dominant living things on land, but their greatness did not ensure survival.

A chemical infamous for its toxicity may have played a surprising role in launching life on Earth.

Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months. This discovery, made with the Gemini South telescope in Chile, one half of the International Gemini Observatory, offers a rare glimps…

It may be one of the most iconic sights in the night sky, but astronomers have never seen the Helix Nebula like this before.

Oregon State University researchers have painted a clearer picture of the coastal marten, a secretive, ferret-sized forest carnivore renowned for its cuteness but nearly driven to extinction by human activity in the 20th century.

A new analysis suggests modern satellite networks could suffer catastrophic collisions within days of losing control during a major solar storm. The phrase “House of Cards” is often associated today with a Netflix political drama, but its original meaning ref…

Neurons in the bird eye’s inner retina lack a blood supply. Finding how these neurons function without oxygen reveals a role for an enigmatic eye structure.

In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst examine a longstanding, paradoxical thought experiment in statistical physics and cosmology known as the "Boltzmann brain" hypothesis—th…

In the quest for room-temperature superconductivity, international physicists have uncovered a link between magnetism and the pseudogap.

The Swarm Garden: An array of modular robot agents that adapt to changing conditions for living architecture.

Eyes on a face’s front or side enable a brain to perceive images. Fossil evidence suggests that two light-sensitive organs on top of ancient vertebrate heads generated images, too.

Look to the skies to see the jellyfish-shaped phenomenon.

Bask in modern luxury while taking in the cosmos at these astrotourism escapes.

Archaeologists from University College London and the Natural History Museum suggest the findings offer insights into the cognitive abilities of early human ancestors.

Don’t put your telescope away just yet. 2026 is bringing a lineup of meteor showers that might be worth losing a little sleep over.

Winter weather has forced the annual 2-day event which draws thousands to the North Carolina Museum of Natural Sciences to be rescheduled to January 31 and February 1.

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear in many attempts to unite quantum physics and gravity.
