Space exploration is a broad topic covering many facets of deep-space and planetary science. Learn about space probes, Mars Rovers, SETI and other out-of-this-world subjects.
The planned Laser Interferometer Space Antenna, or LISA, will be able to detect the gravitational waves generated by massive collisions in the deep cosmos.
Let's see how much you know about Neil Armstrong, Buzz Aldrin, Michael Collins and the adventure that immortalized them.
And one of the exoplanets in the Teegarden star system could have a temperature range between 32 and 122 degrees Fahrenheit.
Will this groundbreaking clock revolutionize space travel? NASA is banking on it.
Eugene Shoemaker's contributions to lunar science were legendary. In a fitting tribute, NASA sent his ashes to the moon.
It may be supermassive, but snagging this one-of-a-kind pic was no easy feat.
NASA is hoping to begin sending scientific probes to the moon in 2019 on private spacecraft, in preparation for a manned lunar mission in 2028.
NASA's Mars rover Opportunity's last words were: "My battery is low and it's getting dark."
The Apollo 14 mission landed on the moon in January 1971, but what the astronauts brought back could be making history now.
On a galactic scale, that's kind of like finding a tree in your backyard that you'd never seen before.
From rocket launches and eclipses to meteor showers and lunar landings, these are the space events you won't want to miss in 2019.
Things just got more interesting on this enigmatic exoplanet.
Scientists are still trying to come up with a conclusive explanation for the Martian blueberries.
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.
And this hot DOG's ferocious appetite shows no signs of slowing down.
But you can forget about Barnard's Star b bearing any resemblance to our planet.
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.
Maybe there aren't more dimensions beyond the four that we know and love so well.
Fast radio bursts are over in less time than it takes to blink your eye. They come from way beyond the Milky Way. And astronomers can't say with certainty what causes these enigmatic bursts.
The tiny HaloSat probe will investigate a galactic halo of hot gas that may account for missing matter from the early universe.
NASA is launching its new Parker Solar Probe and it will get closer to the sun than any other spacecraft in history. But could we actually touch the sun some day?
The last satellite — Kepler — discovered more than 2,300 confirmed planets. This one is expected to find even more.
It's never too early to start planning!
Scientists have used long-lost data tapes to show that Apollo astronauts probably caused the lunar surface to warm slightly during moon missions in the 1970s.
