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.

Time to open the thirty-first (and next-to-last) door in the advent calendar. Where in the solar system are these dark-rimmed craters?

SOHO was launched more than 15 years ago to study the Sun, primarily; but a side benefit of its constant observation of the Sun has been its ability to notice "sungrazers," comets that are on deadly close approaches to our star.

Today the 365 Days of Astronomy podcast aired my contribution, Small Worlds, about the smaller denizens of the solar system visited in the past year, and due to be visited in the next.

Today the Deep Impact/EPOXI science team held a press briefing that followed up on their very successful flyby of two weeks ago, a status report on what they can say so far about the science that's coming out of the encounter.

Just in time for today's Deep Impact press briefing, which you can watch on NASA TV in a few minutes: I've updated my montage of all the asteroids and comets that have been visited and photographed to include Hartley 2.

On Thursday, November 4, at 13:50 UTC, Deep Impact flew within 700 kilometers of comet Hartley 2. Hartley 2 is the smallest and most active of the five comets that have been directly by a spacecraft, and the first to be visited within the lifetime of its discoverer.

I had to catch up with tasks left undone at home today and didn't have time to write up my notes from the Hartley 2 press briefing, for which I apologize. I'll leave you for the weekend with three cool Hartley 2 pictures.

It was a very happy set of scientists, engineers, managers, and administrators who filled the Jet Propulsion Laboratory's Von Karman auditorium this afternoon to do the postgame show on Deep Impact's flyby of Hartley 2.

Those of you who follow my blog must have known this was coming: now that I got all five new Deep Impact images of Comet Hartley 2 posted and explained, I had to make an animation. Here they are.
Emily Lakdawalla • November 04, 2010
Here's the five close-approach images of Hartley 2 captured today, November 4, 2010, by the Deep Impact spacecraft, collected into one file. Boy, do these images reward close examination!
