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.
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?
It's a celestial gift in the middle of August. Just look up. At night.

The Russian anthropomorphic robot can fire a handgun, do push-ups and even drive a car. Now it's going off into space.
Scientists recently found 12 more moons revolving around Jupiter, bringing its total to 79. Why does Jupiter have so many darn moons? Is there any advantage to that?
And while we're at it, why don't the other planets in our solar system seem to twinkle?
It's never too early to start planning!

The days are getting longer, but don't worry about changing your clocks.
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.
To define the location of objects in the sky, astronomers utilize a system of celestial coordinates, which extends latitude and longitude from Earth's surface into space.
A tiny black hole or a more monstrous neutron star? Astronomers are on the case.
Once upon a time, the sun caught an interstellar orphan and adopted it as its own. It's named 2015 BZ 509.
Europa might be ready to let us in on a secret.
Some scientists think the existence of plate tectonics could be a prerequisite for life. So do they exist on other planets outside of Earth?
NASA astronauts have to undergo serious training before becoming approved for a trip to space. But some of that training is certainly not what you'd expect.
Astronauts will be testing human and bull sperm to see how microgravity might affect future human reproduction in space.
Astronomers have just discovered a gas in Uranus' clouds that does nothing to help the planet being taken seriously.
It's been a while since the sun has hung out with its brothers and sisters in the same stellar nursery, but they're definitely out there, and citizen scientists can help find them.
No one knew exactly what the deal was with ureilites, a rare type of meteorite, until now.
There's a lot of junk orbiting in outer space. But what happens to those abandoned rockets and mission-related garbage when it goes to its final resting place?
