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.


Mars Close Approach is July 31, 2018. That is the point in Mars' orbit when it is nearest to Earth.

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.

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?

Yep, 'Oumuamua was probably kicked out of its own star system by an overbearing gas giant like Jupiter.

Everyone's heard of the blue moon and the harvest moon, but did you know every single moon of the year has a name? Who named them and what do the names mean?

The SpaceX mission to the International Space Station, scheduled for liftoff on April 2, will enable research on everything from thunderstorms to wound healing.

It's called NGC1052-DF2, an ultra-diffuse galaxy located 65 million light-years away, and it might mean that we don't quite know how all galaxies form after all.

Scholz's star buzzed our solar system back when humans and Neanderthals roamed the planet. Turns out that encounter may have shaken up a whole bunch of comets.

Beneath Jupiter's famous swirls and stripes is an environment that's completely unlike anything on Earth.

Plus, a bonus finding on dark matter!

The government's secret Advanced Aviation Threat Identification Program has spent millions researching UFOs and alien life. Are they covering up their findings?

In 2019, the moon will be getting its own 4G network. That could be better service than some of us have here on Earth.
