Explore the vast reaches of space and mankind’s continuing efforts to conquer the stars, including theories such as the Big Bang, the International Space Station, plus what the future holds for space travel and exploration.
Things just got more interesting on this enigmatic exoplanet.
Like Earth, the sun does rotate, but in a different way.
Those stars twinkling in the nighttime sky may actually be crystal spheres. And our beloved star is headed in that direction, too. Eventually.
In this stellar nursery, firstborn stars are ruthless.
The China National Space Administration makes history — and shows the world the dark side of the moon.
Scientists are still trying to come up with a conclusive explanation for the Martian blueberries.
The image, which was created by the European Space Agency, shows the blazing hot orb's northern-most region for the very first time. Pretty cool stuff.
That means it takes nearly 17 hours for a radio signal, traveling at the speed of light from Earth, to reach Voyager 2.
We've identified 11 different times gravitational waves have passed through Earth. Yep, we're getting good at detecting these ripples in spacetime that Einstein predicted.
It is a mind-blowing amount.
After cruising 300 million miles and spending seven months in space, the InSight spacecraft successfully touched down on Mars' surface. How awesome is that?
And this hot DOG's ferocious appetite shows no signs of slowing down.
Dark matter is the most mysterious (and possibly important) material in the universe, and scientists are excited that a storm of the stuff is upon us.
But you can forget about Barnard's Star b bearing any resemblance to our planet.
If you think about it, it'll likely be an alien machine that encounters our probes searching for intelligent life. How's that going to work?
A stunning accusation has been made: About 10 billion years ago, a small galaxy strayed too close to ours, so our galaxy ate it.
The idea behind the "fake" moon is to provide extra illumination to Chengdu, a city in China's Sichuan province. What could possibly go wrong?
Can a moon have a moon of its own?
With the Russian Soyuz spacecraft officially out of commission, what does that mean for space exploration? And more importantly, the crew on the International Space Station?
Back in 2006, the International Astronomical Union decided to demote Pluto to the status of a dwarf planet. A new historical study challenges that designation.
When most people think of NASA, they probably think of astronauts and the Kennedy Space Center. But there's a whole lot more to this 60-year-old organization.
Anders' Earthrise and 8 Homeward are the two moon craters recently named in honor of the 1968 Apollo 8 mission, the first NASA mission to orbit the moon.
It's a small world with an astonishingly long orbit around our sun. And it could lead us to the fabled Planet X.
It dashed through our solar system like a cigar-shaped signal from another star system. But which one? Astronomers are on the case.
Do they even look different?
