Another Earth

Posted in Breaking Thoughts, Thoughts for the Day on December 6, 2011 by TheRocketArtist

Kepler 22b.    That is the name of it.   The discovery was just announced the other day by the NASA Kepler team.   It is the first confirmed discovery of another Earth.   A second Earth.  Really a “Super Earth”, it is 2.4 times the radius of our planet.   Orbiting a star 600 light years away from us with a period of about 290 days.   The average surface temperature is about 72 degrees F.   It lies in what is called the Goldilocks Zone (the Habitable Zone, where liquid water can exist, where conditions are mild and favorable for life).

And this is just the beginning.   We are just on the very edge of being able to detect rocky worlds.   Other Earths.   The odds are that there are thousands, if not millions, of them in our Galaxy alone.   As I said before, in this respect, Star Trek got it right.   I believe in the next decade, we will discover many more Earths, more rocky worlds in the habitable zones of their parent stars.   More Venuses.   More Mars-like worlds.   Our technology is on the verge.  The techniques have been carefully refined over the past decade.   We are on the cusp.

Kepler has hauled 2,326 potential planets in its first 16 months.   If confirmed, they will quadruple the already known and confirmed 700 planets in the Exoplanet catalog.   And we have just scratched the surface.  This Galaxy must be buzzing with worlds.   Swarms of  hot Jupiters.   Neptunes.   Earths.   And what does that mean for life?   It happened here.   Was it just an accident of Nature?    The elements and atoms that compose the Universe are everywhere the same.   The forces that govern physics operate identically all over the Universe.   Newton’s laws.   Kepler’s laws of planetary motion.  Einstein’s Relativity.   All hold everywhere the same.   Why not?   Why not life on other worlds?   If my conjecture is correct, and we will find many thousands more Earths in the Milky Way, the odds are high, it seems to me, that life exists out there in our Galaxy.

And what of the rest of the Universe?   There are a hundred billion galaxies in the known Universe.   If each galaxy contains several millions of worlds around its billions of stars, then you must multiply that by a hundred billion.    Perhaps i’m an optimist, although by the statistics I would say I’m a realist, but I feel that this Universe must be positively teeming with life.    We have only just begun to look.    We have only just looked up and glanced around and, stunned and startled, but curious just the same, noticed the worlds beyond our shores.   Other Earths.

Stay tuned….

Do Worlds Exist Beyond “our lonely Eden”?

I wrote the following piece for the Daily Bruin some years ago when I was a columnist there, but I wanted to revisit it because so much has happened since then.   At that time, we knew of no extrasolar planets for certain.   Now we know of at least 700, with the Kepler mission adding potentially thousands more.   And some of those are Earth-size worlds. We have just begun to realise Carl Sagan’s dream of an “Encyclopedia Galactica”.   It’s kind of amusing to think about, but Star Trek got it exactly right.  There must be millions of worlds in this Galaxy alone.   We’re finding them at the rate of roughly 1 per week.   And we’re beginning to see rocky smaller worlds.   To see other ways that solar systems have evolved.   The Galaxy is positively rippling with planets.   And life?   We’re beginning to study these worlds for real–their orbits, their atmospheres, whole planetary systems that are different from our own.   And all this in the last  6 or 7 years.   Soon we will be charting other Earths.   And what of the other 100 billion galaxies in the known Universe.  What if they’re teeming with worlds too?   They probably are.    All the more reason for us to keep venturing outward on our voyages of discovery.  Because, as Ray Bradbury once wrote…when we get back, we’ll know ourselves for the first time.   The “Martians” will be us.   We are the explorers.
