New geological data indicate that marine life is somewhat resilient to warming in the tropics. Chris Fokkema, Earth scientist at Utrecht University, discovered that tropical algae were largely unaffected by a number of periods of global warming of up to 1.5 d…

NASA's groundbreaking James Webb Space Telescope has given us an astonishingly detailed peek inside the layers of Uranus' upper atmosphere.

A physicist proposes that consciousness is the fundamental basis of reality, with matter and spacetime emerging from it.

For 2,600 years, an unbroken stone slab kept its secret. When archaeologists finally moved it, they found four bodies exactly as mourners left them.

The types of glass that we encounter in everyday life, such as window glass or smartphone screens, are disordered solids. This means that they consist of particles locked in place, like those in solids, but arranged randomly, similarly to how they would be in…

Liftoff is scheduled for today (March 1) at 7:50 p.m. ET.

You're not prepared for its size.

Iron isotopes show that salty seawater pockets beneath the ice were as cold as −15°C.

Researchers think they aren't primarily used for defense

One of the least-known creatures on Earth has surfaced alive for the first time, ending a long-standing marine mystery.

Jupiter may be the king of planets in our Solar System, but in other star systems across the galaxy, even larger planets orbit billions of miles from their stars – in places where traditional formation theories struggle to explain them.

Elon Musk says his obsession with the red planet is cooling.

Scientists have pulled off a feat long considered out of reach: getting light to mimic the famous quantum Hall effect. In their experiment, photons drift sideways in perfectly defined, quantized steps—just like electrons do in powerful magnetic fields. Becaus…

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree, creating the so-called “Hubble tension.” Now researchers …

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

The first bubble of hot gas seen around another star has been spotted around the "Moth," just 117 light-years away.

The microwave laser, or maser, is produced by colliding galaxies and is so powerful it may warrant an exotic classification: a gigalaser.

In 1974, physicist Stephen Hawking described the potential for tiny, primordial black holes that existed at the dawn of time to explode — and reshaped what we knew about these cosmic behemoths.

The Moon isn't full just yet.

Six planets will appear close together after sunset in a rare planetary parade. Here is how and when to see this beautiful sky event.

Interactions between neighboring materials is mediated by virtual photons.

In shaking up its Artemis lunar program, NASA's new moon plan looks more like the Apollo missions of the 1960s. Instead of landing on the surface on Artemis III, NASA hopes to do so on Artemis IV.

Will humanity extend into the far future? It's likely many of us think it should. The problem is that each of us, individually and collectively, act otherwise—we are destroying the environment and climate at every turn. Now a group of scientists is arguing th…

The largest moon of Saturn is bigger than Mercury, yet for all its conspicuousness, scientists don't know exactly how it came to be.

Scientists found compounds in asteroid samples that are essential for life on Earth. They could also contain molecules necessary for forming consciousness.
