Physicists have increasingly begun to view life as information-processing “states of matter” that require special consideration.

It is humanity’s biggest step yet into the Solar System.

Physicists recently created Coordinated Lunar Time, a time zone for our Moon.

Freethink’s weekly countdown of the biggest space news, featuring a stranded space factory, Jeff Bezos’ new moon lander, and more.

Asteroid 2024 YR4, which could devastate a city’s worth of humans, has gone from 1.2% to 2.3% to 2.6% to 3.1% chances of impact. Here’s why.

Seeking life beyond the Solar System, we first look to the closest star systems with Earth-like planets. Here’s why that’s not good enough.

This first-of-its-kind image offers a detailed look at the magnetic fields within the Central Molecular Zone.

From LIGO, there weren’t enough neutron star-neutron star mergers to account for our heavy elements. With a JWST surprise, maybe they can.

A new SETI study shows how far the field of technosignatures has come.

There are 40 billion billion black holes in the universe. Here’s how our Solar System stacks up against ten of them.

It’s not about fairness. It’s about using every possible advantage.

Teller and Sagan debated fiercely over nuclear proliferation. But was the conflict as personal as it was intellectual for Teller?

The structure of our Solar System has been known for centuries. When we finally started finding exoplanets, they surprised everyone.

If there’s life lurking on the moons of Saturn and Jupiter, could our instruments even detect it?

Fears of celestial collisions — and calculations of their likelihood — go back to the very origins of modern science itself.

Sunita Sah hopes that by redefining defiance, we can build societies that allow people to live more authentic lives.

DESI, by mapping galaxies, has claimed they see evidence for dark energy evolving by getting weaker. But that’s only one interpretation.

Following the advent of human space flight, NASA began naming missions after children of Zeus.

It’s not just fun: DNA origami has the potential to revolutionize engineering at the nanoscopic scale.

Voyager 2 flew past Uranus in 1986, finding a bland, featureless world. Now, in 2023, JWST’s sights are similar. There’s a reason for that.

You can’t throw a DART at everything in space.

This technological feat changes our cosmic history.

Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.

NASA was dangerously cavalier about the dangers of the shuttle launches.

There are billions of potentially inhabited planets in the Milky Way alone. Here’s how NASA will at last discover and measure them.

Yes, NASA’s Perseverance rover found organics on Mars. So did Curiosity. Unfortunately, that doesn’t mean anything in the search for life.

Tech designed to fuse atoms might be able to clean up space, too.

Experts say it’s likely space junk—and there’s plenty more where that came from.

The DART mission tested whether it’s possible to deflect an asteroid by crashing something into it.

Like Mars today, Venus used to be a sci-fi superstar. Recent discoveries could re-ignite our interest in Earth’s “evil twin.”
