Veteran NASA astronauts Bob Behnken and Doug Hurley are about to star in the biggest spaceflight event of the decade.

The new image could be the first direct evidence of the site of a planet's fiery birth in interstellar space.

Once you are in the shuttle and strapped in, you are just waiting until the rocket lights. Everything is still until that rocket lights. Then you are really going somewhere.

Light travels at a staggering 186,282 miles per second, but even with the speed of light, the distance between Earth and Mars seems incredibly vast when you watch the travel take place in this data visualization.

It's an incredibly satisfying video, watching the fuel burn out on Saturn V, Space Shuttle, Falcon Heavy and the Space Launch System rocket.

The idea of beaming solar energy to Earth with radio waves is decades old. But this weekend, the technology gets its first test in orbit.

A "year" here lasts almost twice as long as Earth.

Moon conspiracy theorists say if there's no air on the moon, dust shouldn't be flying around. The Action Lab demonstrates whether dust can kick up inside a vacuum.

David Wilcock and Corey Goode are peddling salvation, protection from the "illuminati deep state," and bogus COVID-19 explanations to millions on YouTube.

A NASA physicist says he resolved a paradox in a hypothetical warp drive. But despite experiments, we have a long way before we can travel through folded space.

The Martian surface is a radiation hot zone. But ancient lava tubes might offer explorers safety from the cosmic bombardment.

There's something quite meditative about the whole process — perfect for a work from home afternoon.

A Chinese rocket around 100 feet long launched earlier this month and will likely plunge back into Earth's atmosphere some time Monday, becoming the most massive object in decades to fall out of orbit uncontrolled.

Harold White left NASA in December to join a new nonprofit focused on building the technologies to bring humans to the outer solar system and beyond.

Seán Doran, a citizen scientist image processor, captured high resolution images of the sun over a week, and the result is a spectacular short film entitled "Sun Dance."

The invisible point of darkness resides in a double-star system just 1,000 light-years away.

The videos aren't proof of extraterrestrial life, but that doesn't mean they aren't interesting.

At just 1,000 light-years away, an object in a nearby star system could be our nearest known black hole — but not everyone is convinced.

A virtual photo trip through the dancing spheres of Jupiter and its four major moons: Io, Europa, Ganymede and Callisto.

Mysterious patterns in orbits of small bodies in the outer solar system could arise from the gravity of a massive disk of icy debris rather than an undiscovered giant world.

Scientists say our host star is surprisingly inactive — but that malaise might do us good.

The new discovery adds to a growing pile of evidence that Mars may have been more hospitable to life in the distant past.

NASA Astronaut Michael López-Alegría shares some timely tips on how to be alone, how to develop a daily routine and how not to kill your quarantine team.

With my job on the Mars Color Imager, I gained a lot of perspective on our place in the solar system.

From Alderaan to Kijimi, Sith lords sure do love to blast planets to smithereens. So how powerful are Star Wars' doomsday weapons anyway?

Recently unclassified footage from Navy jets appears to show UFOs moving in weird ways. Turns out, not so much.

The sun seems a little less active than hundreds of similar stars in our galaxy, which could play a role in why life exists in our solar system.

Astronomers have detected a third exoplanet in the Kepler-88 system more than 1,200 light-years away from us and this one dwarfs anything in our solar system.

"It is technically sound, but there have been issues that have come up on almost every level."

While reviewing 999 photos he'd captured through the night, Prasenjeet Yadav spotted a bright green fireball streaking down the sky and illuminating the sky in one of his frames.

The former Senate Majority Leader says the "American people deserve to be informed" about UFOs.

The first documented case of a meteorite striking a human being. It happened on August 22, 1888 and unfortunately the falling meteorite killed the man and left another paralyzed.

Each color identifies a different sediment or rock formation. The darker colors depict highlands while the reds and purples show volcanic activity.

Physicists have proposed extra cosmic ingredients that could explain the faster-than-expected expansion of space.

Oh also, it makes you blind and stupid, too.

The three videos were originally released by former Blink-182 singer Tom DeLonge.

Beyond the impenetrable cosmological horizon is the unobservable universe: vast, possibly infinite, and maybe the likeliest location for alien life.

When the Allies vanquished Nazi Germany in 1945, the U.S. captured many of the Germans' powerful V-2 rockets. Those seized rockets didn't stay in Europe for long.

That the Shuttle resulted in many technological and scientific advancements is undeniable. The question is whether those benefits were worth the cost. Regrettably, the only plausible answer is no.

lack holes, by definition, are so dense that not even light can escape. But ask any astrophysicist, and they'll report that black holes are among some of the brightest objects in the universe. What's going on here?

What we thought was a planet may have been something else entirely.

"Fomalhaut b" was detected in 2004 but by 2014 it disappeared. How? Scientists think it might not have been a planet at all.

An international team of scientists have discovered an exciting Earth-sized exoplanet that's capable of supporting liquid water.

In yet another win for Albert Einstein's theories, scientists report the first ever detection of "Schwarzschild precession" around a black hole.

Particle physicists have released the results of a decade-long search, taking us a crucial step closer toward understanding where all of the universe's antimatter has gone.

How did matter gain the edge over antimatter in the early universe? Maybe, just maybe, neutrinos.

The bizarre newfound world resides in the mostly barren "hot Neptunian desert."

Back in 2016, a telescope spotted a supernova flaring so brightly that it far outshone its own galaxy. The exploded star continued emitting radiation for more than 1,000 days, unleashing more energy than any supernova previously documented. But that's only the start of the story.

The BepiColombo, a joint orbiter operation between the Japan Aerospace Exploration Agency and European Space Agency, filmed our planet from a few different angles and in varying speed.

Simulations led to this new origin story for the first known visitor to our solar system.

A trip to the moon later this decade should be safer, but it won't be safe.

Unsurprisingly, given they were locked in a fight for survival, relatively few onboard images were taken. But imaging specialist Andy Saunders created sharp stills from low-quality 16mm film shot by the crew.

A newly funded concept envisions a kilometer-wide radio telescope built inside a crater on the far side of the Moon. Whoa.

Is the universe's expansion the same everywhere? New research suggests it's not — which could have huge implications for our understanding of the cosmos.

New observations reveal that an "extraordinary" optical illusion on a massive scale is making a jet from the galaxy 3C 279 appear to move 20 times faster than the speed of light.

There are more than 150 confirmed moons in our solar system — we ranked 'em all.

Bennu has the distinction of being the subject of the highest resolution mosaic ever made of any planetary body.
