Space

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.


Astronomers have been thinking a little more out of the box in the hopes of explaining the weird behavior behind Tabby's Star.

Researchers used laser-plasma-based accelerators to simulate the sort of radiation that astronauts and spacecraft might encounter in outer space.

And that actually might pose a problem when it comes to the search for life on other planets.

If we're going to colonize Mars, we're going to need to figure out how to live off the land. Martian soil might be strangely suited for that task.

A beautiful ribbon of light in the nighttime sky is generating a lot of talk — and some mystery, too.

The strange forces at work on Saturn's largest moon would make for some sweet sand castles.

Plus, we throw in one reason to get excited anyway.

The "virtual telescope" is first getting up close and personal with Sagittarius A*, the supermassive black hole at the center of our galaxy.

We might be only a few years away from seeing whether potentially habitable worlds are inhabited. How cool is that?

Solving a math problem could get us one step closer to meeting E.T., so why haven't we figured out the Drake Equation by now?

And solving that issue could go a long way toward making our planetary neighbor habitable.

European scientists are inviting gamers to become citizen scientists, sifting through real astronomical data to spot undiscovered planets orbiting other stars.

Energized subatomic particles bombarding Earth from outer space can cause the electronics inside laptops, cell phones and other devices to crash.

Say hello to the newly discovered TRAPPIST-1 system, which is just 39 light-years away and filled with seven Earth-like planets.

After the Soviet Union launched Sputnik I in 1957, the space race was on. And what followed was decades of secrecy that dominated its space program.

The first results are in from two groundbreaking NASA studies. What they show could have huge impacts on the future mission to Mars.

Scientists have a new idea, and it has to do with gravitational attraction and repulsion.

Engineers devised a way to levitate and control matter using acoustic waves, and they're sharing their plans with the public.

A total solar eclipse and a comet flyby are on the list of fascinating astronomical happenings 2017 has in store.

Satellites have found evidence of massive underground channels formed by molten rock on the moon. They could be stable enough to house lunar pioneers, a study suggests.

Are all the aliens hanging out without us?

Hawking is working with NASA and a few high rollers to send a tiny, unmanned spacecraft to our closest star system.

It's a bird, it's a plane, it's supermoon! Aside from being bigger and brighter than a regular moon, does a supermoon affect anything on Earth?

Astronaut John Glenn, the oldest human to ever travel to space, has died at age 95. He had a lot of adventures, both on this planet and off, before he did though.

NASA researchers say they may have made a breakthrough with electromagnetic drive propulsion, but other scientists have their doubts.
