At just four light years away, Proxima Centauri is our closest solar neighbor. The recent discovery of the new exoplanet Proxima D, has reopened the discussion of whether the proxima system is our best chance at reaching another Earth....

Planet Earth is our home, but unfortunately humans have caused a great deal of damage to it. How have humans impacted Earth and what are the consequences? This clear and informative program answers this question through the use of...

Sun is obviously the hottest thing in our Solar System, but it is a mere candle when compared to several other stars and stellar phenomena, particularly supernova. A supernova is a transient event that marks the last evolutionary stage...

Not all of the objects in the solar system are named after Greek and Roman gods -- some are named after literary figures, movie stars, and don't get us started on what people think Earth is really called.

Today, we're going to talk about how the Earth moves, but to do that, we're going to have to go way back to the early days of the galaxy! Processes that happened before the Earth even formed have led us to the geographic patterns and...

Ever wonder what seasons are like on other planets? Astronomers are beginning to find out, and SciShow Space explains how they know, what causes the change in seasons, and what 'summer' might mean on distant worlds.

We've already learned a lot about the solar system, but sometimes the most fascinating things are what we DON'T know.

Asteroids are small, rocky objects that orbit the sun, just like the rest of the planets and celestial bodies in our solar system. Although asteroids are present throughout the solar system, most of them live in the asteroid belt—a...

What are the planets outside our solar system like? Astrophysicist and TED Fellow Jessie Christiansen has helped find thousands of them (and counting), and the variety is more wonderful and wild than you might imagine. She shares details...

Normal maps are useless inside black holes. At the event horizon - the ultimate point of no return as you approach a black hole - time and space themselves change their character. We need new coordinate systems to trace paths into the...

The earth has an axial tilt of about 23.5 degrees. While this tilt is responsible for shaping our planet's climate and seasons, it also played a crucial role in shaping life on earth. What would have happened if the...

We’ve assembled an all-star group of ecologists, naturalists, and creative thinkers for an urgent but hopeful conversation about the environmental pressures bearing down on Earth’s rich spectrum of species. Join legendary oceanographer...

There are many planets in the universe, but very few of them have qualities to support life Taking one celestial body at a time and determining whether it supports life would be slow and inefficient. So, astronomers look for certain...

The sun is the primary force in Earth's climate system. Sunlight warms our world. Sunlight drives atmospheric and oceanic circulation patterns. Sunlight powers the process of photosynthesis that plants need to grow. Sunlight causes...

IBEX is a new NASA mission that will study the interaction between the solar wind and the material beyond our Solar System called the interstellar medium. The solar wind flowing out of the sun inflates a bubble that we call the...

Earth's climate system has been remarkably stable over the last 20,000 years or so. Human civilization developed in that time span, and our world's average temperature warmed by about 5 degrees C to the temperature it is today. This...

Astrum investigates some examples of the longest and shortest years that we know of. The differences are mind-boggling!

Upon viewing the Stars and Galaxies video series, students will be able to do the following: Explain that our solar system is part of the Milky Way galaxy. Understand that the Milky Way galaxy is huge and contains billions of...

Cern's Large Hadron Collider routinely collides particles at energies equivalent to a fraction of a second after the Big Bang. If this worries you, then the following fact will either put you at ease or scare the hell out of you. And...

It may be that for every star in the universe there are billions of microscopic black holes streaming through the solar system, the planet, even our bodies every second. Sounds horrible - but hey, at least we’d have explained dark matter.

In this video we are going to look at what viruses are. Viruses are a type of microorganism. They are too small to be seen with the naked eye: much smaller than bacteria, and about 100 times smaller than human cells. They come in many...
