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

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

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

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

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.

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

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.

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.

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

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

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

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

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 costs of such an endeavor would be extremely high, while the potential payoffs would be uncertain.

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

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

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

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.

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

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

2023 will see the launch of new rockets, the return of OSIRIS-REx, and a mission to Jupiter that could help us find extraterrestrial life.

The surface of asteroid Bennu is more like a plastic ball pit than the Moon.

Ever since the Big Bang, cataclysmic events have released enormous amounts of energy. Here’s the greatest one ever witnessed.

We may have discovered alien life already but rejected the evidence too quickly because it seemed false at first glance.

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

When the Hubble Space Telescope first launched in 1990, there was so much we didn’t know. Here’s how far we’ve come.

Each of our three nearest stars might have an Earth-like planet in orbit around it. Here’s what we’ll learn when we finally observe it.
