Mars in a Minute: How Long is a Year on Mars?

One year for any planet is measured by how long it takes to orbit once around the sun. Since Mars is farther away from the sun than Earth, it takes almost twice as long: Earth orbits in 365 days. Mars orbits in 687 Ea...

Full 360° view of our moon from NASA’s LROC Wide Angle Camera

From the Wide Angle Camera (WAC) of the Lunar Reconnaissance Orbiter (LRO), providing a very wide field-of-view, view Earth's moon from all sides. It was created from 110,000 high-resolution WAC images that were digit...

A Fictive Flight Above Real Mars

Fly by the moon Phobos towards Mars, and then fly across the Red Planet's surface thanks to NASA’s High Resolution Imaging Science Experiment (HiRISE) imagery and three months of digital imaging work by Finnish filmma...

Fly though the International Space Station in Ultra HD 4K

Take a serene 18 minute tour of ISS in 4K, a rare point-of-view that you'd experience as an astronaut floating through International Space Station's passageways. The video begins and ends within its renowned Cupola ob...

Earthrise from the moon, captured by JAXA Kaguya Spacecraft

Between 2007 and 2009, the Japan Aerospace Exploration Agency (JAXA) captured more than 600 incredible photos and videos of the moon with an orbiting Selenological and Engineering Explorer (SELENE) mission spacecraft,...

To Mars and Back In 150 Seconds

How does sending humans to Mars work? How long does it take to go there and come back? How do they set up shelter on the Red Planet? What about space radiation? TIME's Jeffrey Kluger gives us an animated primer: To Ma...

Behind-the-scenes with Terra Bella’s satellites

What might we learn if we could observe the patterns in humanity's mass activities -- mining, clear cutting, ships moving through ports, erupting volcanoes, ground conflicts, etc -- over time? What if we could do that...

NASA’s SDO captures the Mercury Transit in time lapse

From 7:12am to 2:42pm ET on May 9, 2016, Mercury passed between Earth and the Sun, a rare occurrence called a transit. NASA’s Solar Dynamics Observatory (SDO) captured incredible footage of the closest planet to the s...

Newton’s Three Laws of Motion

Follow four astronauts on a six month journey from Earth to Mars, and see how Newton’s Three Laws of Motion -- 'Newton' referring to English physicist and mathematician Sir Isaac Newton -- can help us understand and p...

Astronaut Leland Melvin on Returning Home From Life In Space

What's it like to come back home to our Blue Marble after you've been floating around in orbit? NASA astronaut, engineer, and former football player Leland Melvin explains his return-to-Earth readjustment experience i...

Evidence of a Ninth Planet

Thanks to mathematical modeling and computer simulations by CalTech researchers Konstantin Batygin and Mike Brown, we now have strong evidence that there's a large planet -- about 10x Earth's size -- orbiting in an ex...

This is What Outer Space Does to Your Body

NASA astronaut, engineer, and former football player Leland Melvin explains how the human body changes when it leaves the confines of Planet Earth. Your body may become taller, your heart might get smaller and change ...

What Does Earth Look Like From Space? An Astronaut’s Perspective

What does Earth look like from space? Perhaps it's easy to take that view for granted if you've watched enough videos... but imagine for a moment that you are watching it from a small window in a house-sized vehicle o...

General relativity & why GPS wouldn’t work if we didn’t know about it

General relativity, what Albert Einstein said was the happiest thought of his life, basically expands upon the idea that "the laws of physics are the same everywhere". Light and gravity behave in the same way for you....

Lunar Eclipses Explained + Does The Moon Really Orbit The Earth?

"As bright as the moon looks in the night sky, what we're really seeing is sunlight, and the percent of its face that's illuminated depends on where it is in relation to the Earth. At the point in its orbit when the m...

How the International Space Station Was Built – TED Ed

How do you build something that's the size of a six bedroom house and weighs more than 320 cars, all while orbiting the Earth at 17,398 miles (28,000 km) per hour? Assemble it piece by piece, and with lots of collabor...

The Rosetta Mission – A claymation tale of science & adventure

In August 2014, after ten years of traveling, the Rosetta space probe and its lander Philae made a historic rendezvous with Comet 67P/Churyumov–Gerasimenko, and in November 2014, Philae landed/bounced onto the comet's...

Why Do We Put Telescopes in Space? – MinutePhysics

If we have excellent telescopes here on Earth, why is it so important to put telescopes like the Hubble Space Telescope into space? This MinutePhysics video explains the challenges of being an earthbound telescope, fr...
