Well, not so much in “our†old town as in another old town on another planet, in another solar system.
That’s right kids, scientists have discovered a planet in another solar system. Now while this may not be so exciting to some of you you (OK, any of you), due to the fact that they have already discovered some 800 planets outside our solar system already, but here’s the kicker.
This particular planet just may be the first one that is solid rock.
That’s right, a team of European astronomers has confirmed the first rocky extrasolar planet.
Scientists have long figured that if life begins on a planet, it needs a solid surface to rest on, so finding one elsewhere is a big deal.
"We basically live on a rock ourselves," said co-discoverer Artie Hatzes, director of the Thuringer observatory in Germany. "It's as close to something like the Earth that we've found so far. It's just a little too close to its sun."
So close that its surface temperature is more than 3,600 degrees Fahrenheit, too toasty to sustain life. It circles its star in just 20 hours, zipping around at 466,000 mph. By comparison, Mercury, the planet nearest our sun, completes its solar orbit in 88 days.
"It's hot, they're calling it the lava planet," Hatzes said.
I’m posting it here because I was thinking that our resident geologist, science geek, and Imperious leader would find it fascinating. The planet (called Corot-7b) was first discovered earlier this year by the Europeans, who then watched it dozens of times to measure its density to prove that it is rocky like Earth. What’s even cooler, is that Corot-7b is apparently in our general neighborhood. It circles a star in our winter sky that is only some 500 light-years away. (Each light-year is about 6 trillion miles, so if Walt goes off to explore it he won’t be back for dinner, Alison, sorry.)
Now that another rocky planet has been found so close to its own star, it gives scientists more confidence that they'll find more Earth-like planets farther away, where the conditions could be more favorable to life, Boss said.
"The evidence is becoming overwhelming that we live in a crowded universe," Boss said.
So, I’m off to having a good day today. Hot Jets!
