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

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.

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

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.

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.

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?

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

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

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

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

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

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

This technological feat changes our cosmic history.

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

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.

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

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

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

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

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.

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

Spaceguard shows that we can manage risks to the extinction of humanity — if only we put our mind to it.

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

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

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

Sometimes, going “deeper” doesn’t reveal the answers you seek. By viewing more Universe with better precision, ESA’s Euclid mission shines.

Methane is a shorter-lived but more potent greenhouse gas than carbon dioxide. Cleaning it up could have a quick impact on global warming.

Dinosaurs and other beasts were once thought to be the “undisputed masters” of Venus.
