Explore the four inner rocky planets, as Jessi and Squeaks take you on a tour of the solar system!

Planet Earth is the jewel of the solar system—the shimmery blue oceans, the verdant green forests, the wispy whimsical cloud formations. Saturn is the only competitor for most gorgeous planet with that giant ring system. Hmm… what if we...

Some tidally-locked exoplanets might actually be more habitable than astronomers initially thought, and we have some ideas about how Peter Pan disks can last so much longer than other protoplanetary disks.

A new international study has measured the densities of the seven Earth-size planets around TRAPPIST-1 with extreme precision

Join us on a thrilling journey through the animal kingdom as we explore the record-breaking sizes of the planet's most massive creatures. From the majestic blue whale, the heaviest animal in the world, to the African Bush elephant...

A conversation with Lynn Rothschild, astrobiologist and synthetic biologist in the Earth Science Division at NASA’s Ames Research Center in Silicon Valley.

Extreme environments full of life on Earth have led researchers to expand the definition of habitability to something that includes many more planets, potentially leading us to evidence of living things in a dramatically shorter time!...

Improving batteries is a tough problem, but it’s also an important one because in many ways the future of our planet also depends on the future of batteries. Luckily, scientists are on the case, figuring out ways to give this essential...

Life on Earth requires three things: liquid water, a source of energy within a habitable range from the sun and organic carbon-based material. But life is surprisingly resilient, and organisms called extremophiles can be found in hostile...

You might think weather on earth is pretty crazy, but at least we don't have an apocalyptic shockwave to worry about every 111 days.

Do other planets have weather? It turns out that, yes, they do! But, the weather isn't all the same on other planets because of things like atmosphere. In this episode of Crash Course Kids, Sabrina takes us on a tour of the weather on...

3 Surprising Things Matter Does Under Extreme Pressure

From launching a new satellite, to finding diamonds from a lost world, researchers have been hard at work transforming how we think about our planet, the solar system, and the rest of the universe.

The weather down here can get pretty crazy. But we got curious and asked: just how extreme can weather actually get on planet earth? So we decided to travel the world in search of answers and discovered not only some fascinating answers,...

The land surface of the Earth accounts for 1% of its total volume. Travel from the core to Earth's surface, examining the layers that make up our planet. Earth Science - Geology - Learning Points. The Earth is made up of four layers. The...

Something heavy seems to be causing Uranus and Neptune to move in a different orbit than what we can currently account for with the celestial objects we know of. Is there a 9th planet? Does planet 9 exist? Is planet X...

Dive into the fascinating characteristics of Mercury and Venus, the closest planets to the Sun in our solar system. Discover Mercury's extreme temperatures and rapid orbit, and learn why Venus, with its scorching heat and beautiful...

An increase in Earth’s rotational speed could have various impacts on life: ranging from increased earthquakes and tsunamis to a shortening of the length of the day. People could be floating in central Africa while the polar ice might...

This video provides a description of the planet Mercury, the closest planet to the sun in our solar system. It highlights key facts about Mercury, such as its diameter, mass, lack of moons, and orbit period. The video also mentions the...

Without a spacesuit, there is no chance of surviving in the scary cosmic void. In science fiction movies, we often see people’s heads exploding or being frozen by the apparent pressure differential or lack of heat, respectively. As long...

NASA scientists are seeking a strange breed of northern lights in the Arctic. When these auroras shine, Earth’s atmosphere leaks into space.



In the tiny Arctic town of Ny-Ålesund,...

The Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite has been scanning Earth for 20 years and now has a long enough record to help support climate change research. AIRS data on Earth’s atmosphere are...
