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...

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 just imagine for a moment that you are watching it from a small window in a house-sized vehi...

Why Isn’t It Faster To Fly West? – Minute Physics

When you think about how the Earth rotates -- to the east -- it would seem to make sense that a plane flying west would meet its destination sooner... after all, isn't the planet is spinning toward the plane? In fact,...

Solar Wind Strips Martian Atmosphere – NASA Goddard

In 2014, NASA's MAVEN (Mars Atmosphere and Volatile Evolution mission) spacecraft measured the speed and direction of ions escaping from Mars. The data collected as it orbited the Red Planet is visualized in this NASA...

The Rosetta Mission Asks, “How Did Our Solar System Form?”

How does studying Comet 67P/Churyumov–Gerasimenko start to shed light on some of the questions we have about the origins of the universe? For example, how did gas and dust form our solar system? How did we get from st...

Weather vs. Climate + Severe Weather – Crash Course Kids

Weather vs. climate... are they the same thing? In this episode of Crash Course Kids, Sabrina Cruz explains the differences: Weather refers to the day to day conditions of where you are on the planet. Climate refers t...

Exploring Space with Shape-Shifting Robots

Can a "skwishy" baby toy help inform how next generation robots explore other worlds? Vytas SunSpiral's team at NASA Ames Research Center joined forces with Alice Agogino's Mechanical Engineering lab at UC Berkeley to...

Building the solar system to scale in the Nevada desert

"Every single picture of the solar system that we ever encounter is not to scale. If you put the orbits to scale on a piece of paper, the planets become microscopic and you won't be able to see them. There is literall...

The Basics of Freshwater + Water, Water, Everywhere?

With around 326,000,000,000,000,000,000 gallons (326 million trillion gallons) of water on Earth, covering 71% of the Earth's surface, you'd think it would always be easy to find water we can drink. In fact, only arou...

Fast and Light to Pluto – The New Horizons spacecraft’s flyby

From The New York Times' Out There series, get a deeper understanding of the New Horizons spacecraft's mission, history, and July 14, 2015 flyby of Pluto, a historic and illuminating glance at the last of our solar sy...

Space X’s Falcon 9 falls back to Earth to The Blue Danube

To the tune of Johann Strauss II's Blue Danube waltz, Space X's Falcon 9 falls majestically back to Earth in real time. Falcon 9 is a two-stage rocket that transports satellites into orbit, and powers the Dragon space...

How Do Greenhouse Gases Actually Work?

The Earth and the Moon are essentially the same distance from the sun, yet the two rocks have very different surfaces thanks to our Earth's atmosphere. It shields us during the day, and at night, it traps enough heat ...

The Four Spheres (Geo, Bio, Hydro, & Atmo) with Crash Course Kids

The ground or geo-sphere, water or hydro-sphere, air or atmo-sphere, and life or bio-sphere: Earth and everything on it can be organized into these four distinct yet interconnected subsystems. Knowing more about each ...

The Hubble Space Telescope Reflects the Cosmos

"When the Hubble Space Telescope was launched from the Space Shuttle Discovery in 1990, NASA called it the greatest advance in astronomy since Galileo. Instead, within days it became a laughing stock. Hubble had an ei...

How Big Is The Sun? – MinutePhysics

Even though the sun and the moon look around the same size in the sky, the sun is 400 times bigger than our planet's moon and is 400 times farther away. Compare the sun's 150,000,000 km (93,205,679-ish miles) distance...

Stunning Views of Earth From the International Space Station

The Blue Marble... The Pale Blue Dot... that magnificent Overview Effect... This is what our astronauts experience from the International Space Station, and what we get to see via videos like this, and this, and this,...

NASA: Satellite Tracks Saharan Dust to Amazon in 3-D

Watch 182 million tons of dust ride the wind out of Africa's Sahara Desert in 3D, as tracked from 2007 through 2013 by lidar, thanks to CALIPSO, the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation sa...

Wanderers: Humanity’s Future Expansion into the Solar System

With narration by Carl Sagan, borrowed from an audio recording of his 1994 book Pale Blue Dot: A Vision of the Human Future in Space, this is Wanderers, a bold science fiction short by digital artist and animator Erik...
