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

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

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.

In all the known Universe, Earth is the only planet known to have native life. What should guide us in expanding humanity beyond our world?

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

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

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.

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

With JWST, Chandra, and gravitational lensing combined, evidence has emerged for the earliest black hole ever. And wow, is it a surprise!

Since 1962, humanity has been sending messages into space with the intent to make contact with intelligent extraterrestrials. Are those efforts worth the risks?

A recent measurement has simultaneously settled an ongoing scientific debate while puzzling scientists.

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

Astronomer Adam Frank asks: With so many extraordinary claims, why can’t anybody produce the proof?

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

Only nine weeks later, the Wright Brothers achieved manned flight. The pathologically cynical always will find a reason to complain.

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

Our Moon is full of craters, basins, and ancient lava flows. But two large lunar Grand Canyons have the same origin: a single, giant impact.

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

Finding life beyond our Solar System requires understanding its host planet.

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

“You’ll be able to fly twice as fast as a Boeing or Airbus, and it’ll be like the cost of flying business today.”

Despite no experimental evidence showing that gravitons exist, they remain a respectable concept in the world of professional physicists.

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

Viewing Uranus’s largest moons with Hubble, astronomers hoped to find darkening on the trailing side. They found the exact opposite instead.

You don’t need to be a scientist or a philosopher for facts, reality, and the truth to matter. The alternative is simply known as bullshit.

Even from a single pixel, multiwavelength data taken over time can reveal clouds, icecaps, oceans, continents, and even signs of life.

There was a lot of hype and a lot of nonsense, but also some profoundly major advances. Here are the biggest ones you may have missed.

We’ve wasted our time and resources ideologically policing and punishing each other for far too long. Here’s a better route to prosperity.

Somewhere out there in the Universe is the heaviest neutron star, and elsewhere lies the lightest black hole. Where’s the line between them?

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