If there’s life lurking on the moons of Saturn and Jupiter, could our instruments even detect it?
It’s not just fun: DNA origami has the potential to revolutionize engineering at the nanoscopic scale.
60% of all potentially dangerous asteroids remain undetected.
If your computer crashes, it might be due to a star that exploded somewhere in the Universe millions of years ago.
Experts say it’s likely space junk—and there’s plenty more where that came from.
On July 12, 2022, NASA will release the first science images taken with the James Webb Space Telescope. Here’s what to hope for.
The largest hazardous asteroid found in the last 8 years showcases a little-known class of planet-killers. And we’re woefully unprepared.
We may have discovered alien life already but rejected the evidence too quickly because it seemed false at first glance.
NASA is creating a planet habitability index, and Earth may not be at the top. With our current data, ranking habitability is guesswork.
After decades of development, whether NASA’s Webb succeeds or fails all comes down to five critical milestones that are only days away.
Experts believe they could cut the time it takes a rocket to reach Mars by up to 25%, shaving about two months off the trip.
With its first view of a protoplanetary disk around a newly forming star, the JWST reveals how alone individual stellar systems truly are.
For many, it was just a successful launch like any other. But for scientists around the globe, it was a victory few dared to imagine.
An effect called the “urban heat island” means that temperatures are often 10 degrees higher in cities, according to NASA.
Sometimes, going “deeper” doesn’t reveal the answers you seek. By viewing more Universe with better precision, ESA’s Euclid mission shines.
The structure of our Solar System has been known for centuries. When we finally started finding exoplanets, they surprised everyone.
Knowing that technology would advance in the future, NASA put some moon rock samples into storage without opening them. Now, they have.
Spin, spin, spin — fire! The startup’s radical system could make satellite launches cheaper and cleaner.
Until recently, we were only able to view Venus’s surface with radar or by landing on the planet. It was believed that Venus’s surface was entirely obscured by clouds; NASA’s Parker Solar Probe proved otherwise.
How can you “touch the Sun” if you’ve always been inside the solar corona, yet will never reach the Sun’s photosphere?
Sooner or later, Earth is going to be hit by a large enough space object to cause significant damage to humanity. Stopping them isn’t easy.
1.9 billion years ago, a star’s explosive death created a black hole. Its light just arrived at Earth. But did it set a cosmic record?
Tech designed to fuse atoms might be able to clean up space, too.
Memorial day is a time to remember veterans killed in the line of service. These spaceflight heroes deserve to be remembered, too.
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.
With launch, deployment, calibration, and science operations about to commence, here are 10 facts that are absolutely true.

Data from NASA, ESA, and Roscosmos suggest that long durations in space cause changes in the brain, some of which are linked to vision problems.
Somewhere out there in the Universe is the heaviest neutron star, and elsewhere lies the lightest black hole. Where’s the line between them?
