Many galaxies formed fast after the Big Bang, but about half of them suddenly stopped making new stars and it looks like this is literally because they ran out of gas. And with new instruments and techniques, we are now finding lost...

Scientists are constantly researching different ways people could potentially live on Mars. Start making your future Martian travel plans with this collection of videos about the unique challenges of putting humans on Mars.

We've learned a lot about Mars over the years, but we keep uncovering new mysteries - important, fundamental aspects of The Red Planet that we just can't explain. Here are three of them.

One way to help us live on Mars would be to terraform the planet. Some scientists think we might be able to do that by giving it a new magnetic field!

It sounds like science fiction, but journalist Stephen Petranek considers it fact: within 20 years, humans will live on Mars. In this provocative talk, Petranek makes the case that humans will become a spacefaring species and describes...

In this video Paul Andersen describes the structure and explains the properties of molecular solids. High intramolecular forces hold electrons and reduce conductivity, whereas low intermolecular forces decrease the melting point. ...

Virus hunter Nathan Wolfe is outwitting the next pandemic by staying two steps ahead: discovering deadly new viruses where they first emerge -- passing from animals to humans among poor subsistence hunters in Africa -- before they claim...
