https://www.nasa.gov/press-release/nasa-telescope-reveals-largest-batch-of-earth-size-habitable-zone-planets-around

Today is a day I have been waiting for for years. Not only has NASA announced they have found 7 Earth size exoplanets that are close to us (you know, considering...) but at least three of them are apparently habitable. This is the largest group of habitable planets surrounding a single star that we have yet to discover and they could be the homes of our descendants.


please don't use misleading title. the planets are only said to be located in the "habitable zone", and there's no confirmation the planets themselves are hospitable to humans. the article claims " the chances are highest with the three in the habitable zone" - it doesn't mean they are highly likely to be hospitable, but among the 7 planets, those 3 mentioned are considered to have "better odds" of being hospitable (this in the most vague sense - it could be a ~25% chance for the 3 planets as opposed to ~10% for the other 4)



Spitzer, Hubble, and Kepler will help astronomers plan for follow-up studies using NASA's upcoming James Webb Space Telescope, launching in 2018. With much greater sensitivity, Webb will be able to detect the chemical fingerprints of water, methane, oxygen, ozone, and other components of a planet's atmosphere. Webb also will analyze planets' temperatures and surface pressures – key factors in assessing their habitability.

so we'll have better information a year from now, but of course, we'll just be receiving information about the planet's past existence.

Things are really going to change when that telescope gets launched in 2 years I heard after the beta testing one of its first missions is to investigate that alien mega structure and find out once and for all what it is that keeps stumping scientist every theory that has been purposed so far has been shot down.

Our descendants will sure have a long journey to make, i don't envy them.


Descendants? with life extension in our lifetime that may be possible it may be us going :o


I don't fancy a trip to space, i'd rather just stay on Earth by myself.

This makes me wish someone would invent a warp drive.

I think others already pointed out the various caveats from this piece of news.

Aside from those, it'd be a whole lot faster just to build a bunch of large space colonies around our solar system's Lagrange points.

When room run out at those colonies, start expanding them toward each other until we have Dyson Rings and finally, a full-on Dyson Sphere.

Humanity doesn't need to venture out of the solar system until the sun runs out of fuel.

If anything we could use the sun as the needed boost of power to send us to another star system.

I'm pretty confident that i'll die before Earth does, i'm not worried.

You wouldn't want to live forever if you had the chance ?

Well of course i don't particularly want to die but i wouldn't want to live forever either, especially if that meant going to space.

Someone sounds scared >.> why not live forever ?

I'll never live long enough to get off planet. Interstellar travel may be a pipe dream cut short by our future circumstances and/or the limits of our science and the laws of physics.
I may never see proof of alien life, even microbes from our own solar system. Or the signs of long dead alien civilisation, if they ever existed. Time and space are indifferent to my wishes. I'll have to settle for our probes and space technology to bring any word back to me.

But I still have my imagination .

They should send messages to the systems they have found to see if there are any responses in the future.

For the planets to be "habitable" in the common meaning would mean at the very least oxygen in the atmosphere which would be a truly amazing discovery as it would confirm alien life. But if they have water they may well be terraformable which would probably take thousands of years even if we had the tech for it. But hey, it'd take at least a few hundred years to get there from here anyways. I wonder what the masses of the planets are and if any of them would have earth-like gravity.
