New habitable extrasolar planet discovered

Located 16 light years away, Gliese 832c has been identified as one of the best places to look for life.
Discovered by Robert A Wittenbyer from the University of New South Wales, the new planet is thought to have a mass five times that of the Earth and orbits its parent red dwarf star once every 36 days.

Despite these differences however Gliese 832c is a prime candidate in the hunt for habitable Earth-like worlds. Located within its star's habitable zone, the planet is believed to be one of the top most likely places to find life outside of our solar system.

"The planet might have Earth-like temperatures, albeit with large seasonal shifts, given a similar terrestrial atmosphere," astronomers wrote.

"This makes Gliese 832c one of the top three most Earth-like planets according to the ESI (i.e. with respect to Earth's stellar flux and mass) and the closest one to Earth of all three, a prime object for follow-up observations."

But there is no evidence that red dwarfs poison all of their planets and render them lifeless. But I suppose anything is possible. Like life on red dwarf planets being possible for instance. Until science can confirm just one red dwarf system lifeless, which means each earthly or watery planet it has is thoroughly examined tip to toe, odds that life does or does not exist in such systems remain equal. How can this be a lie? I simply choose to think a positive over a negative. Are you always so easily offended by what people think? My decision is based on science, that a red dwarf is a sun th...

Cool, keep me posted if your ever wrong now, you hear!

I am not the one that is continually showing my ignorance of astronomy and physics. There is nothing wrong with not knowing a lot about these subjects, people have different interests. But you keep posting about astronomy as if you know a lot about the subject, while it is painfully obvious that you don't. Why don't you educate yourself on the subject instead of lookin foolish all the time ? This is just a friendly suggestion. PS: I will keep you posted, but I am never wrong.

Red dwarfs do last an awfully long time -- an order of magnitude or more longer than the sun (by last I mean stay on the main sequence). Therefore any life there could be there a long time. At least early in their lives they tend to be unstable and shoot off flares the sun would certainly envy but any life nearby would not. Maybe they settle down, but even so just one every million years or so ain't healthy -- indeed, less so as life in such a regime does not evolve, even if it could, any sort of defense. Also relevant is the fact that planets orbiting a red dwarf necessarily are much clos... [More]

Yes i agree Perhaps, i think the big question is if an atmosphere can provide the necassary protection. Or water. Or caves. Or moons . Are you sure all the planets will be tidally locked though? Billions of red dwarfs means billions of planets means billions of combinations. This link is interesting it confirms all your doubts and adresses the complications which might befall hypothetical living organisms on these planet types. http://arxiv.org/pdf/1405.1025.pdf True, if we get the opportunity to reach just one of these planets though, we should analyse it with the same determination w...

Jeepers, but 5 times the mass! Conventional science says we might be able to get there quickly enough, assuming we survived the impact, but moving around would be a big problem!

Moving around would be the least of your problems, see .

We need to get closer to these planets to get closer to the truth, thats the only way we can eliminate the earthlikes for sure. Or listen here to the broadcast... http://www.kavlifoundation.org/science-spotlights/spotlight-live-hunt-other-worlds-heats#.U8JXqWIaySM
