Late yesterday, NASA announced the discovery of a planet just outside our solar system that is the most like Earth to be found so far.

Located using the Kepler universe-trotting telescope, the planet that has been named the poetic Kepler 22-b is a balmy 72 degrees.

That’s because it is in a habitable “Goldilocks” zone (see chart below) and seems to circle a sun much like our own.

Yes, I am hoping this Earth 2.0 is just like Counter-Earth from the comics, too.

But, at more than twice the size of Earth, it is likely all ocean and rock and gas at this point, and is more than 600 light years away. So, if any geek is planning a star trek, it will take a lot of rocket fuel.

For anyone who loves the idea of a doppelgänger–someone out there who is you except different–this trailer for much-anticipated indie film, “Another Earth,” is for you.

It’s about astrophysics and accidents and aliens and alienation, on the occasion of the “discovery of a duplicate planet in the solar system.”

Deep stuff!

Here’s the moving movie trailer:

Pluto’s sullied celestial reputation has been restored. In brazen defiance of the International Astronomical Union–which famously demoted Pluto to dwarf planet in 2006–the State of Illinois this week passed a resolution restoring Pluto’s planetary status.

In Illinois, anyway. Apparently, Clyde Tombaugh, who first discovered the planet, was born on a farm there.

“WHEREAS, Pluto was unfairly downgraded to a ‘dwarf’ planet in a vote in which only 4 percent of the International Astronomical Union’s 10,000 scientists participated,” the resolution reads. “And WHEREAS, Many respected astronomers believe Pluto’s full planetary status should be restored; therefore, be it RESOLVED, BY THE SENATE OF THE NINETY-SIXTH GENERAL ASSEMBLY OF THE STATE OF ILLINOIS, that as Pluto passes overhead through Illinois’ night skies, that it be reestablished with full planetary status, and that March 13, 2009 be declared ‘Pluto Day’ in the State of Illinois in honor of the date its discovery was announced in 1930.”

Scientifically, there really is no question [that Pluto should be reclassified]. Either Pluto is not a planet, or many other things are planets. Which is a better choice? I want my planets to be more special, not less special, so I favor Pluto not being a planet.”

–California Institute of Technology astronomer Michael Brown, 2004

Delisted from the pantheon of celestial bodies back in 2006 for its weaker than expected planethood, and then pronounced second best to Eris, its recently discovered neighbor, Pluto is no longer the solar system’s bastard stepchild. Yesterday, the International Astronomical Union, which struck Pluto from the planetary rolls, decreed that all “transneptunian dwarf planets similar to Pluto” will henceforth be called “Plutoids.” Pluto shares the designation with Eris, the only other … non-planet to meet the IAU’s criteria for Plutoidenism.

The IAU clearly views the new classification as an honor for the humbled Pluto, but to Plutevangelists it’s just one more insult. “It’s just some people in a smoke-filled room who dreamed it up,” Alan Stern, a former NASA space sciences chief and principal investigator on a mission to Pluto, told the Associated Press. “Plutoids or hemorrhoids, whatever they call it. This is irrelevant.”
