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.

Mike Griffin started the press conference, and got right down to business announcing the launch delay and indicating that the actuators as well as other technical problems are responsible.
Ryan Anderson • December 04, 2008
At 12 noon EST. I know what the announcement is, but I'm not allowed to tell you! How frustrating is that?!

As I post this, NASA is holding a press conference in which they are announcing that the Mars Science Laboratory's launch date will be slipped by two years.

I just heard, via this article at Universe Today, that the sample cache on MSL has been canceled.

The period of Mars solar conjunction has just begun, which means that a host of scientists and engineers whose day jobs entail interaction with the five active Mars spacecraft are getting a five-week break from the daily grind of operations.
Ryan Anderson • November 20, 2008
I've known about this for a little while but it was finally made public: The list of MSL landing sites had now been trimmed to four.

There was a worrying update posted on the JPL website for Spirit today: an early-season dust storm has darkened its skies enough that its solar panels produced only 89 watt-hours of power yesterday, sol 1,725. Neither rover has ever, ever seen power production levels that low, not even during last year's massive dust storm.

Another day, another drive: on sols 1,693 and 1,695 the Opportunity rover conducted two more lengthy drives to the south, totaling almost 200 meters. On the other side of the planet, Spirit is FINALLY in motion again.

Victoria crater, the site of a Mars year's worth of study, is now far over the horizon, as Opportunity has lately completed a series of very long drives. Opportunity is once again sailing the sand seas of Meridiani Planum.

An article in the September 26 issue of Science neatly explains why only the southern half of Mars is strongly magnetized.
