Kepler-62f: A Possible Water World

The artist's conception depicts Kepler-62f,a super-Earth-size planet in the habitable zone of a star smaller
and cooler than the sun, located about 1,200 light-years from Earth in the constellation Lyra. The small
shining object seen to the right of Kepler-62f is Kepler-62e.

Kepler-62f is a remarkably Earth-like planet about 1,200 light-years from our planet. The world is only 1.4 times bigger than Earth and is in orbit around a star that is somewhat dimmer and smaller than the sun. It orbits in what is believed to be the habitable region of its star.

The planet was announced in 2013 as part of a larger bonanza of seven exoplanets announced around the stars Kepler-62 and Kepler-69. Another notable discovery at the same time was Kepler-62e, which is also close to Earth's size (at 1.6 times the radius) and in the habitable zone.

Separately, a modeling study of Kepler-62e and Kepler-62f suggested that the planets would likely be engulfed in water, which could lead to life that is very different than our own.

"There may be life there, but could it be technology-based like ours? Life on these worlds would be under water with no easy access to metals, to electricity, or fire for metallurgy," modeling lead author Lisa Kaltenegger, of the Max Planck Institute for Astronomy and the Harvard-Smithsonian Center for Astrophysics, said in a statement in 2013.

"Nonetheless, these worlds will still be beautiful blue planets circling an orange star — and maybe life’s inventiveness to get to a technology stage will surprise us," she added.


This diagram compares the planets of the inner solar system to Kepler-62, a five-planet system about 1,200 light-years from Earth in the constellation Lyra. The five planets of Kepler-62 orbit a star classified as a K2 dwarf, measuring just two thirds the size of the sun and only one fifth as bright.

Discovered by Space Telescope

Kepler-62f was discovered using the Kepler space telescope, an observatory that discovered thousands of exoplanet candidates before it ceased its primary mission in 2013. (As of late that year, NASA was evaluating new missions for the telescope, which was in an extended mission and now has two malfunctioning reaction wheels originally intended to keep it pointed in the right direction.)

The planet makes a complete circle of its red dwarf star every 267 days and orbits at about the equivalent distance of Venus to the sun in our own solar system. Although this puts the planet far closer to its star than Earth is to the sun, the red dwarf does not produce as much light. This means that the region around the star where planets could have liquid water is much closer than that of our own solar system.

Kepler-62f, however, is the farthest known planet in its system and may require quite a bit of cloud to insulate the planet and keep water above freezing. If that were the case, water would likely be there in abundance. Researchers pointed out that life on Earth itself was believed to have started in an aquatic environment.

"Look at our own ocean — it is just absolutely full of life," said Bill Borucki of NASA's Ames Research Center in Moffett Field, Calif., leader of the team that discovered the two exoplanets, in 2013. "We think, in fact, life [on Earth] might have begun there."

The key to a more advanced civilization, however, may lie in pockets of dry land. Technology (as we would understand it, at least) would be difficult to develop unless any alien creatures could work out of the water.

"We might not have gotten off four legs" if humanity's predecessors came to be on Kepler-62e or Kepler-62f, Borucki added in the interview. He said a human that somehow found him or herself on the Kepler-62f would have no trouble walking around, as the gravity is gentle.

Breathing, however, would be another matter. The soupy atmosphere of Kepler-62f could prove difficult for humans to breathe, unless they were to come with special equipment, researchers pointed out.

"If you want to write a science-fiction story, and you land on both [62e and 62f], at least be sure that on f you don't want to take your mask thingy off," Kaltenegger said.

-62f

I thought this was about the temperature in my back yard this morning.

And to your point, I'm sure the Zero Regime will get oright n that just as soon as they tell NASA to stop making Muslims feel better.

A more foolish request I have not had tossed my way in years. Congratulations, you’re somewhat unique. I don’t even know what the Koine Greek for ‘natural selection’ would be, much less the Hebrew. But since Jesus taught Physics to Philip, as related in John’s fourteenth chapter, and described His interdimensional nature with ‘for I am in the Father and the Father is in me’, then I suppose you will be terribly disappointed that He didn’t answer your query the way you demand it be posed. Sorry about that ...

back. sorry for my tardy reply. i have no aggument with John. God certainly created dimensionality, and His creation is all within Him. He is omnipotent, omnipresent, and all knowing.

i’m at a loss to it’s relevance at this point. you’re way off my original point in this thread.

i’ll just mention in my defense of my “foolishness” that *selection* itself is an ancient concept, with well known application (domestication of animals, etc). it’s really nothing new at all, even though Darwin’s so called “theory” has recast it as a replacement for God in creation.

it seems to me that God could have called out natural selection explicitly instead of going out of His way in Genesis to emphasize the *supernatural* means of His creation (e.g., forming Adam directly from matter).

well, i’m done with this, but have the last word if you want. God bless.
