We are that much closer to making space travel a reality and SpaceX is helping make that possible.

NASA’s Juno spacecraft is a trooper as it continues its 2-year-long mission.

Scientists may have discovered up to 31 more cryovolcano remnants on Ceres, and the Iridium flares are slowly being allowed to burn up in our atmosphere, so see them while you still can!

Hank tells us four incredible things about Jupiter's sixth moon, Europa.

Several rovers on Mars's surface are currently in operation, including one you might not have heard of: China’s Zhurong rover. It's already spent over a year on the Martian surface and is bringing us ever closer to understanding the...

Humans can’t go too far above or below sea level unaided, but there are some complex forms of life that CAN survive at super high elevations or in the deepest parts of the ocean.

A freshly-mopped floor is slippery, but a wet shirt is super-clingy... so what's the deal? Why can water make some things slick and other things sticky?

Sounds in the ocean can travel more than 10,000 miles - that's halfway around the world! Here's how.

Way out in the solar system, the heat of the Sun drops off dramatically, so the gas giants get just a tiny percent of the solar radiation that reaches Earth. Instead, their weather is fueled from the inside out!

Humans are full of microbes. Humans also went to the Moon. Does that mean we left colonies over there?

The extreme mass of neutron stars leads to enormous gravitational pulls, resulting in nearly perfect spheres. But those imperfections, or mountains, might be able to help us spot more neutron stars in the future! And back on Venus, more...

Hint: It's not your collection of awesome refrigerator magnets!

Anti-Satellite weaponry, giant X-ray lasers and kinetic impact missiles nicknamed the "Rods from God." Find out about the history of the real star wars that have been waged over the past 50 years.

The constant motion of our oceans represents a vast and complicated system involving many different drivers. Sasha Wright explains the physics behind one of those drivers -- the concentration gradient -- and illustrates how our oceans...

About 1200 years ago, Earth may have experienced one of the rarest and most powerful cosmic events a planet can be exposed to: a gamma-ray burst. If it did, well, let's just say that we, as living things on Earth, are lucky it wasn't worse.

Every morning, Helios unleashed his golden chariot, and set out across the sky. As the Sun God transformed dawn into day, he thought of his son, Phaethon, below. To prove to Phaethon that he was truly his father, Helios decided to grant...

You might not want to sign up for the Enceladus Ice Hockey League... And some researchers have an idea that might make the Big Bang model more accurate!

Researchers mapped the mammoth family tree by extracting DNA from fossils. Also, scientists found some sessile animals living under Antarctica's ice shelf, and they're really cool.

Arthritis and injury grind down millions of joints, but few get the best remedy -- real biological tissue. Kevin Stone shows a treatment that could sidestep the high costs and donor shortfall of human-to-human transplants with a novel...

You may have seen rock sculptures seemingly defying physics in your newsfeed, but what's actually happening?

Today Hank wraps up this look at your integumentary system and all the hard work it does protecting you from and helping you interact with the world around you.

Maybe you'd like to just hear about one topic for a while. We understand. So today, let's just watch some videos about Gravity. We'll learn about why we don't fly off into space, what mass has to do with it, how does air resistance work,...

The idea that the Moon is a blown-off chunk of the Earth is known as the giant impact hypothesis - but the presence of carbon on the Moon throws this hypothesis into question.

Dolphins are one of the smartest animal species on Earth. In fact, their encephalization quotient (their brain size compared to the average for their body size) is second only to humans. But exactly how smart are they? Lori Marino...
