Astronauts on the International Space Station dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station.

Today, NASA announced that there is...occasionally...flowing, liquid water on the surface of Mars. What?!

Sunspot AR2297 was extremely active in the middle of MArch sending out many flares and CME's. It triggered several nights of extreme aurora activity including the highest level seen in this solar cycle.

Our family had a great time with this Loki Lego Launcher project. Not only did our kids get a big sense of accomplishment by successfully sending a balloon to near space, but it was a ton of fun and we got some fantastic footage too.

In June 2013, a group of friends launched a weather balloon a few miles from Tuba City, Arizona. Enjoy the video of our launch preparations, video footage, and some data analysis of the flight.

What is dark energy? What is dark matter? Well, if we knew exactly we would have a nobel prize - we know that they exist though. So what do we know about those strange things?

Watch it move...

The view of life in space is getting a major boost with the introduction of 4K Ultra High-Definition (UHD) video, providing an unprecedented look at what it's like to live and work aboard the International Space Station. This important new capability will allow researchers to acquire high resolution - high frame rate video to provide new insight into the vast array of experiments taking place every day. It will also bestow the most breathtaking views of planet Earth and space station activities ever acquired for consumption by those still dreaming of making the trip to outer space.

The atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today.

So you know a bit about the Big Bang - but did you know that you can physically see or hear it in your every day life? Find out how 'static' often contains remnants from this monumental event.

Enjoy SpaceX launch footage in Ultra HD 4K. All footage used in this video was shot in 4K. If your connection is slow, toggle to 1080 HD for smoother playback.

How did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.

When you stare up at the night sky, you might think that the universe is really black, but that's just because our eyes aren't sensitive enough to see the billions and billions of multicolored stars out there. Ever wonder why certain stars are certain colors? And what color is our sun, really? If we looked at enough stars, could we figure out the average color of the universe?

Counting stars from the shore of the cosmic ocean...

Could we stop an asteroid on a collision course for Earth?

Miss The Solar Eclipse This Year? Watch This Incredible Footage Of It!

Only one side of the Moon is visible from Earth because the Moon rotates about its spin axis at the same rate that the Moon orbits the Earth, a situation known as synchronous rotation or tidal locking.

The Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the universe. CERN scientist James Gillies tells us what accounts for the remaining 96% (dark matter and dark energy) and how we might go about detecting it.

The true scale of our cosmic neighborhood. Whoa.
