Not the Onion: NASA discovers 715 new planets

(CNN) -- Our galactic neighborhood just got a lot bigger. NASA on Wednesday announced the discovery of 715 new planets, by far the biggest batch of planets ever unveiled at once.

By way of comparison, about 1,000 planets total had been identified in our galaxy before Wednesday.

Four of those planets are in what NASA calls the "habitable zone," meaning they have the makeup to potentially support life.

The planets, which orbit 305 different stars, were discovered by the Kepler space telescope and were verified using a new technique that scientists expect to make new planetary discoveries more frequent and more detailed.

"We've been able to open the bottleneck to access the mother lode and deliver to you more than 20 times as many planets as has ever been found and announced at once," said Jack Lissauer, a planetary scientist at NASA's Ames Research Center in California.

Launched in March 2009, the Kepler space observatory was the first NASA mission to find planets similar to Earth that are in, or near, habitable zones -- defined as planets that are the right distance from a star for a moderate temperature that might sustain liquid water.

Tuesday's planets all were verified using data from the first two years of Kepler's voyage, meaning there may be many more to come.

Feb 2014

Calling it mind boggling doesn't even do it justice. The amount of energy required to perform such a feat is so beyond the grasp of humanity that we will likely never see something like it come into fruition.

I'm talking about harnessing the energy of the entire sun at one time. Our first spacecraft has just departed the heliosphere. We've barely entered infancy when it comes to exploring the cosmos.

The more likely possibility is that, following the singularity, assuming we even make it to that point without blowing ourselves to hell, our more evolved technological offspring will obtain similar technology.

Why Bother Thinking About Something We Can't Build Yet.


Jeffrey LeeJeff Lee has recently been named Project Lead of the Icarus Interstellar X-Physics Propulsion & Power Project.

XP4 focuses on potential far term technologies that utilize methods of engineering spacetime itself, some of which may present the possibility of faster-than-light-speed travel. XP4 projects are at a much lower TRL (Technology Readiness Level), and are decades, possibly centuries or millennia away from actual development.


You'd be surprised at how many people are actually thinking along these lines now.

for the record, the technologies I am playing with right now in fiction are two that are very much in development right now

Solar Sails

Ion Engines

And a couple that are not in development but possible. One requires a dark matter containment field and folds space time across a higher membrane. It requires both the power of the sun, and computational power that we can barely comprehend or imagine.

Trust me, will be doing a lot of reading on this site. Thanks for that.

Yes, I know the Fermi paradox, but if you are advanced enough to travel interstellar space why pray tell me would you make contact with us?

Now if you are an aggressive species and decide to make contact because you need those resources, I don't think humans will survive that encounter.

I know it ranks a few folks here, but lets assume for a sec that UFOs are real. That would be your anthro class from Gliese 586, and would not be that unlike our own anthropologists researching more primitive societies. I used Gliesse 586 since it is quite brutally honest on the life zone, and a life candidate.

Of all the possible futures, I like the Star Trek type ones the best.

Edited to add: I agree with you (I think Miguel Alcubierre's ideas are interesting) that we'll figure it out IF it is feasable within the constraints of the laws of physics. I think it's possible that there is no techincal wizardry that can pull it off- it may simply not be doable.

I'm sorry, I like the story, but I get frustrated with the limited science understanding and grasp of basic astronomical facts, among the general public at times. Yes, we now know there are thousands of planetary systems in our nearby galaxy. The cosmos as we understand it today is vastly different than it was a few decades ago. We have learned more about our immediate galactic environs in the past few decades, than all of human history prior, many times over.

11. Billions of planetary systems in the Milky Way.
Wed Feb 26, 2014, 05:34 PM
Feb 2014

Probably many, many billions.

There's hundreds of billions of stars, most of them red dwarf stars which live effectively forever, simmering away, slowly burning their meager resources. All that came into existence are still burning. A really good place to look for life, IMHO.

Kepler put the lower limit at about 70 billion, but nobody believes, with about 200 billion stars that there are only 70 billion planets. Everywhere we look, at almost every star, we find planets. The model of star birth also predicts planets. Only the largest stars are unlikely to have them, and those are few and burn up very quickly.

Just filling in some details for others.

First, lack of heavier elements - if the star formed when the universe was much younger, the planet (and the life on it) will have far less iron and other heavy elements. AFAWK, that would make it more difficult for life to form.

Also, older means more time for the lifeforms to have wiped themselves out - we could have ended the cold war with a very spectacular 15 minutes.

But we currently have a sample size of 1, so we really don't know.

42. You are, of course, correct.
Wed Feb 26, 2014, 08:00 PM

But there are many, many red dwarfs which are not first generation.

As far as wiping themselves out, we don't know anything about alien sociology or psychology. It is likely to be quite divergent to human. That's always the problem with these speculations. One has to try not to anthropomorphize the aliens. Damned difficult not to do. As you aptly point out, we have one data point.

Nevertheless, I think it's fairly inevitable that there's life out there, and also likely intelligent life. The numbers are just too large for there not to be. (That's a very unscientific way of putting it, though.)

While 700 new planets sounds like a lot, it is basically like picking up a handful of sand on the beach and comparing what you are holding in your hand to all the rest of the sand on our entire planet. That is how small this discovery actually is.

It is still very exciting of course and we could learn a lot from this discovery, but 700 planets is not anywhere near as much as it sounds.

Unfortunately the Kepler telescope died. Its mission, like that of the Hubble Deep Field, was to only take a slice. Probability dictates that the slice represents the whole. To find so many smaller planets in that tiny slice starts to add clarity to the Drake Equation. As we learn more about biology we could add some more certainty as well. It seems originating single cell bacteria is pretty common, but multicellular is much rarer. This is based on the time it took on Earth - are we a typical example?

I personally think we have at most four technological civilizations in our galaxy at any one time. This is based on how long it took for us to reach this point and the many keyhole events we went through to get here. I would love to be proven wrong (please in my lifetime).

I of course have no way of proving it, but I believe that a large percentage of the stars have planets which sustain life circling them. They are all so far away from us that we will probably never definitively prove another technological civilation exists, but I have no doubt there are many of them out there.

of 4.7 billion years only one species on this planet developed technology. Is there any potential candidate besides hominids? Did our mere advance stop others?

Evolution probably does not result in technology. It could be a happenstance related to the other factors that influenced our development. We know forming a eukaryotic cell takes time (2.7 billion years or more). Metal rich planets (those around mostly 2nd or later generation stars) are 8 billion years old or less. Kepler looked at about the oldest known cluster NGC 6791 -12,000 light years away.
