As a huge Star Trek fan, I got really excited when astronomers first started discovering planets outside our solar system. Then more and more planets were identified, and none of them were hospitable to (Earth) life, and we didn’t find any aliens, and the whole thing got kind of boring even for a space geek like me.
Here’s a reminder that finding new planets is still something worth celebrating.
From the Surprising Science blog:
The latest in a long string of recent exoplanet discoveries could be the most exciting one yet: A planet called HD 40307g, roughly 44 light years away, appears to be the most likely candidate to harbor life of any exoplanet we’ve discovered to date. Larger than Earth, but smaller than a gas giant, the planet seems to be in the “goldilocks” zone of its star system, the region with the right balance of heat and cold to potentially allow for liquid water.
That’s all for this week. See you back here on Monday!
