Now that astronaut Scott Kelly is back on earth, scientists are studying how all that time altered his body.

After months of pestering, Karl finally goes to see a doctor for a prostate exam. As an added bonus, Ricky and Steve get to watch the whole thing on a video monitor.

In a spectacular discovery, a team of scientists came across a 600-mile long coral reef located at the mouth of the Amazon River, all hidden under muddy waters.

See how an asteroid collision could result in the Earth spinning closer to the sun.

Explore the possibility of communication with aliens through satellite signals.

One way the world might end: evil nano-robots.

Could all-powerful robots bring about the end of the world?

Scientists discuss the probability and implications of an alien invasion.

Could super intelligent mutants spell doom for all mankind?

Scientists demonstrate a lab-sized version of a volcanic eruption - the kind that in real life, could spell doomsday for Earth.

Another way the world could end: a freezing, barren, blustery, frigid ice age.

Will the world end in nuclear holocaust brought on by mad scientists, crazed enemies, or computer-controlled warfare?

Will the end of the world be heralded by an unstoppable deadly plague?

NASA's Juno spacecraft will orbit Jupiter for about two years before scientists destroy it. They're destroying it in order to avoid contamination on Jupiter's moon Europa, which could have life.

Jupiter is the largest planet in our solar system, and it also spins the fastest.

CERN's Large Hadron Collider is the biggest particle hunting machine ever built! Beams of particles collide in a detector named Atlas. These collisions trigger an enormous amount of data which is then decoded by Atlas.

For the past two years, Rosetta has been studying Comet67P. It’s discovered some surprising things about comets.

Engineers have developed the most agile jumping robot ever. Dubbed Salto, the 10-inch tall robot could be helpful in future search and rescue missions.

Most comets that we know of live in one of two places, the Oort Cloud or the Kuiper Belt.

The sun’s atmosphere, known as the corona, is millions of degrees hotter than its surface, and scientists may have figured out why. A NASA spacecraft found evidence of “heat bombs” collectively heating up the atmosphere.

In August 2014, the ESAs Rosetta probe picked up a strange ticking sound coming from Comet67P. These sound waves are moving through the comet’s magnetic field.

MythBusters: The Search premieres January 7th!

A look back at two of the biggest news headlines from 2016: Gravitational waves and Proxima b.

2016 saw technology changing the way we interact with our world with new innovations like autonomous vehicles and virtual reality.

From reusable rockets to robotics, engineers began shaping a future in 2016 that most of us cannot yet dream of.

Medical progress came in many forms this year, from nanotechnology and bio printing organs leading the charge to the first successful human trials for CRISPR.

A look at the upcoming missions that will take space exploration to new heights!

The Dark Side of the Sun premieres February 12th on Science Channel.

Solar wind is a constant emission from the Sun that sweeps out into the Solar System. It’s made of particles and plasma.

Sometime’s the Sun’s magnetic field becomes unstable and creates sun spots.

The Sun’s Coronal Mass Ejections not only reach Earth, but should also cat us a lot of money.
