All eyes are on the Moon. We’re going back, this time to stay, right? One of the best resources on the Moon will be the lava tubes that criss-cross the subsurface of the Moon.
As scientists continue to explore the Earth, they’re discovering life, surviving and even thriving in extreme environments. What hints can this give us about what we might find as we search for live on other worlds.
Astronomers are finding even more new extrasolar planets and they’re starting to discover entirely new categories.
How did we get from plain old hydrogen to our current diversity? It came from stars, in fact successive generations of stars.
This time we’re going to talk about Pluto, its moons, the Kuiper belt, and the other icy objects that inhabit the outer Solar System.
