Learn why and how we study exoplanets, and how you can get involved.

Scientists are searching for 100 Earth-like planets around other stars, and you can help.

The habitable zone is the not-too-hot, not-too-cold region around a star where liquid water can exist.

Lava worlds. Hot Jupiters. Earth 2.0 candidates. Here's a rundown of some notable exoplanets.

Some methods almost sound like science fiction: Using gravity as a magnifying glass, watching stars wobble at turtle-like speeds, and searching for tiny dips in starlight.

WFIRST, NASA's Wide Field Infrared Survey Telescope, is the next step in our hunt for Earth-sized exoplanets.

Did you think I was going to skip Uranus? How could I?

Here's yet another of the moons of Uranus for you: Ariel, a near-twin in diameter to Umbriel, but apparently with more interesting geology.

Miranda is the one moon of Uranus for which we have very good images from Voyager 2, and that was a stroke of luck, because low-resolution shots of all of Uranus' moons would have told us that it was, geologically speaking, the most dramatic of the five biggest ones.

Here's Neptune, but not quite like you've ever seen it before.
Emily Lakdawalla • December 17, 2009
Proteus is a weird name for this world. It's the second-largest moon of Neptune, and so it's named (as are all of Neptune's moons) for deities associated with the sea.

Welcome to the tenth post in my "Advent Calendar" -- I am opening a door each day on a different world in the solar system, and I'll be continuing to do so until New Year's Day.

Jupiter has been high overhead at sunset for several months, a brilliant light that's easy to spot even when the sky is still bright at dusk; but it's now moving quickly to the west as Earth speeds ahead of Jupiter's more stately march around the Sun.

Umbriel is the darkest moon in a pretty dark place in the solar system, the Uranus system.

Here is every single image of the last two moons discovered prior to the Voyager 2 encounter, Titania and Umbriel.

I got an urge to dive in to the Voyager image archives and see what exactly we have here on Earth to base our understanding of the Uranian moons on.
