Is Superman on either of these planets?

Awesome.

I dunno. My Mom's pretty hot.

Meh, wake me up when we find one that has hot chicks with pointy ears or green skin.

Or with liquid water. "About Earth's size" just isn't interesting.

The point is the methods of detection have gotten good enough to find an earth sized planet. You didn't expect the first one to be perfect did you?

What I liked was the oh so helpful artist sketch of what an earth sized planet might look like.

Colonists should start saving their tinfoil right away.

I named my last two laptops after Kepler discoveries.

Knight of the Woeful Countenance: gettin closer...

From the article:

it means we're that much closer to finding the ultimate goal: an Earth-sized planet orbiting a Sun-like star in that star's habitable zone, where liquid water can exist.

Every time I hear news like this, I wonder how much longer we'll be waiting to hear that news... and I strongly suspect it won't be too much longer.


Couldn't have said it better myself.

No, but I am so tired/bored of hearing "Hey look! We found another planet. And this one is Earth-like" where 'Earth-like' means double Earth mass and no atmosphere, or molten, or frozen, or whatever.

To me, 'Earth-like' means kinda, you know, like Earth. Something that would kill me in seconds were I there is not, to me, like Earth.

This is why they need to start alerting us to "Class M" planets only.

I prefer H. Beam Piper's nomenclature.

Far Be it asume Fellow farker's aren't scientifically up to date on planet formation theories, BUT

This puts current theories in a BLENDER. This system does not obey BODE's law, It makes no sense.

Kepler has been looking for over 18 moths, It shoud have found some terrestrial sized planet in a near lighter stars
habitable zones by now. Planets around this harbitabily zone, that orbit Red Dwarfts and smaller Orange dwarfs
should have been found since their orbits take from 50 days for a red drawf, or 120 days or so for a SMALLER
orange dwarf. given that they need to wait for 3.5 transits for confirmation (175 day & 420 days. we should have found some by now.

Well, it may mean that terestrial planets 80%-130% with water on their surface is relatively rare.

From the current findings to this date we can infer: for the lighter M dwarf and K orange stars.

The average non-jupiter planet that forms around stars are much bigger than earth
Planets migration is a huge feature of solar system formation.
Orbits do not favor regions where water might be liquid.

If this turns out to be a general Law of solar systems for types of stars then

1) it would explain the Fermi Paradox (where are the aliens)
2) It would give a value to 2 items in the Drake equation, over all making it very unlikely that any ET's exist.

also kepler seems to imply that Not ALL solar systems have sizeable planets. The likelyhood of a transit is 1%
from our point of view, they are examining 100,000 stars, There should be about 1,000 candidates there only
about 550-600.

Something the Kepler team probably doens't want to mention, with this much planet migration,
how many planets get swallowed up by their SUN.
