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.
The discovery calls into question the few things scientists know about these powerful astronomical phenomena.
There are billions of potentially inhabited planets in the Milky Way alone. Here's how NASA will at last discover and measure them.
Do you think you know the Solar System? Here's a fact about each planet that might surprise you when you see it!
When stars form, they emit energetic radiation that boils gas away. But it can't stop gravitational collapse from making even newer stars.
If you think you know how an astronomical nova works, buckle up. You're in for a ride like you never expected.
Earth is the Solar System's only known inhabited planet. Could Venus, if its phosphine signal is real, be our second world with life?
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 James Webb Space Telescope is about to begin science operations. Here's what astronomers are excited about.
We've only seen Uranus up close once: from Voyager 2, back in 1986. The next time we do it, its features will look entirely different.
Researchers have discovered 830-million-year-old microbes living inside a salt rock on Earth. Could the same occur on Mars?
A new study of Martian dust gives insights into the ancient Martian climate. The findings hint at a wetter world.
The observable Universe is 92 billion light-years in diameter. These pictures put just how large that is in perspective.
Atomic clocks keep time accurately to within 1 second every 33 billion years. Nuclear clocks could blow them all away.
In all of human history, only 5 spacecraft have had the right trajectory to exit the Solar System. Will they ever catch Voyager 1?
The high pitches from the flute and the harp would reach your ears before the notes from the tuba and the cello.
Do the laws of physics place a hard limit on how far technology can advance, or can we re-write those laws?
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.
We have long thought that Pluto was completely frozen solid, but the discovery of cryovolcanoes challenges that assumption.
Speculation about the existence of aliens goes all the way back at least to the Greek philosophers. Their arguments will sound familiar.
Everything that gets heated up has to, somehow, radiate that energy away. Here's what we see when that happens in the Universe.
For a thousand light-years in all directions, there's a "bubble" that the Sun sits at the center of. Here's the story behind it.
Europa may be difficult to access. But if a recent study is correct, its subsurface ocean would be more accessible than previously thought.
Most potentially hazardous asteroids remain unidentified. NEO surveyor could change that, but only if it's funded, and soon.
Was there ever life on Mars? Is there life on Mars now? Did it originate there or here, on Earth? All possibilities are fascinating.
