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.

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

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

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

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

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

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

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.

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

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

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

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

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

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

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.

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

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.

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

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

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

If your computer crashes, it might be due to a star that exploded somewhere in the Universe millions of years ago.

The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we’re woefully unprepared.

NASA is creating a planet habitability index, and Earth may not be at the top. With our current data, ranking habitability is guesswork.

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.

60% of all potentially dangerous asteroids remain undetected.

On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here’s what to hope for.

With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.

Memorial day is a time to remember veterans killed in the line of service. These spaceflight heroes deserve to be remembered, too.

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