Europa is fine and all, but where we really need to go is Saturn's moon Titan. Let's look at some cool ideas for probes to fully explore this world.

You'd think Saturn has all the luck, with its awesome rings. But it turns out, living on a planet with rings has consequences, like an impending global apocalypse.

With so much attention on Mars, it's easy to forget there's a whole other Earth-sized planet nearby, worthy of exploration: Venus. And the Soviets worked really hard to tell us what it's like down on the surface of Venus with their Venera program.

In just a few months, NASA's Cassini spacecraft is going to die, crashing into the planet Saturn. Let's look back across the mission's history. What were the highlights? What did we learn?

In what is the biggest announcement in exoplanet-hunting history, NASA has announced the discovery of seven rocky exoplanets around a single star, three of which are potentially-habitable

We've got all this nuclear waste to dispose of, and we've got this superheated fusion ball in the sky. Couldn't we just blast our nuclear waste into the Sun and be done with it?

What's that bright light in the sky? How come I never noticed it before? That's not a star at all, it's Venus, and it is awesome.

In 1859, the Sun gave off the most powerful solar flare on record. A blast of radiation and particles so strong it fried electrical wires and set telegraph towers on fire. What would happen if a solar storm of this magnitude happened today? It would be a very bad day indeed.

Changing another world to support Earth life is called terraforming. But maybe it's a better idea to just change Earth life to live on other worlds.

Not all stars are alone. Some come in pairs and more. And when there are multiple stars in a system, watch the cosmic sparks fly.

We've been so busy wondering how we'll find aliens that we never stopped to consider what we'll do if we actually encounter them. How does an alien discovery get communicated to the media? Who's responsible to craft a response?

You know what would be exciting? Finding life on Mars. What is the best evidence we’ve seen for life on the Red Planet?

Sure, if you've got lots of energy, you can zip around the Solar System. But if you’ve got time and rocket fuel is in short supply, you can take the Interplanetary Superhighway.

When was the first time that the Universe cooled down enough that light could finally move around?

Did you hear that the Universe has 10x the number of galaxies? How did astronomers discover this, and what does it mean for the number of stars?
