Astronomers discover three habitable planets just 40 light years away

Awesome but Just is not a word I would have used there.

Or if you're from the South... "down the road a piece" or "over yonder".

Engage!

So yeah, 40 light years is basically right on top of us.

Well played!

while we still can just to be sure.

Of course, it could be there but like the 1850's. We wouldn't know they were there and they couldn't detect the signals we've been sending for the last 100 years.

If they're smart, they probably don't want such a violent species to know of their existence. Or we don't happen to have turned a radio telescope their way.

But... a brown dwarf? How long can it stay hot enough? A red dwarf has a nuclear furnace, and can burn many times longer than our own hotter star. But a brown dwarf will eventually radiate away its heat of creation. And it takes billions of years to evolve advanced life... Worth further investigation though!!

On edit: the article below lays out a case for brown dwarf planets that could exist in the (continually cooling) habitable zone of a Brown Dwarf for 0.1 to 10 billion years. That's potentially enough time for advanced life to evolve!

The first thing they did in radio wouldn't have been ultra narrow band and highly focused communication. So, before they had that they would have evolved through normal radio and then on to more sophisticated forms of transmission.

And, i don't recall saying they were sending "us" signals. Merely, that we would have picked up the signals they were sending for their own use.

I also get the brown dwarf thing and i agree. I'm trained in the sciences. (Advanced degree in organic chemistry.) So, i was just trying a little humor.

Sheesh, people can be so overly serious.

my jokes stem from terminal science fiction syndrome not contagious.

All we need is to discover even simple life. The likelihood of life appearing on two+ planets within 40 ly of each other would be a good indication that life is common, rather than rare, in the cosmos.

But, i do agree that the impact that 2 stars in the same neighborhood having life would be huge on our grasp of how common life would be off the earth.

Type 1. We're type 0 level civilization

”

He added that encryption would render communication indistinguishable from “cosmic microwave background radiation.”

“If you look at encrypted communication, if they are properly encrypted, there is no real way to tell that they are encrypted,” Snowden said. “You can’t distinguish a properly encrypted communication from random behavior.”

Undetectable Extraterrestrial Signals --"Advanced Civilizations Could Be Using Ghostly Neutrinos or Gravitational Waves"


Several of the world's leading astronomers -- including Great Britain's former astronomer royal, Sir Martin Rees -- believe advanced extraterrestrial civilizations, rather than using different radio waves or visible light to signal, may be using an entirely different communication medium such as ghostly neutrinos or with gravitational waves (ripples in the fabric of space-time) or using communication mechanisms we cannot begin to fathom.




Lord Rees, a leading cosmologist and astrophysicist who is the president of Britain’s Royal Society and astronomer to the Queen of England believes the existence of extraterrestrial life may be beyond human understanding.



In fact, Davies writes in his book, The Eerie Silence, that advanced technology might not even be made of matter. That it might have no fixed size or shape; have no well-defined boundaries. Is dynamical on all scales of space and time. Or, conversely, does not appear to do anything at all that we can discern. Does not consist of discrete, separate things; but rather it is a system,or a subtle higher-level correlation of things.

Are matter and information, Davies asks, all there is? Five hundred years ago, Davies writes, " the very concept of a device manipulating information, or software, would have been incomprehensible. Might there be a still higher level, as yet outside all human experience, that organizes electrons? If so, this "third level" would never be manifest through observations made at the informational level, still less at the matter level.

100 years is a blink in the eye and in fact now since we have gone digital our noise is much less.


Scientists may have an extra challenge when it comes to detecting alien civilizations: a time limit.

A new study suggests that intelligent aliens, if their technological progression is similar to that of humanity's, are likely to have moved away from noisy radio transmissions to harder-to-hear digital signals within a 100-year time frame. That offers Earth just a narrow window in which to pick up any signals from extraterrestrial civilizations.?

"Based on the results that we looked at, if we assume that the civilizations are humanlike with similar technological progress to us, we calculate the probability of making contact is roughly one in 10 million," the study's lead author, Duncan Forgan, told SPACE.com.????

The time it takes a planet to go "radio quiet" dramatically restricts the types of signal it sends into space and our chances for eavesdropping on them, said Forgan, a postgraduate researcher at the University of Edinborough in Scotland. [Poll - Is Earth Ready to Meet an Alien Civilization?]

Forgan and his team applied their technology-development time scale to a simulation of the galaxy, based on the assumption that the pace of an alien civilization's technological progress would be similar to that on Earth. Based on this simulation, the researchers determined the 1-in-10 million odds of humans accidentally stumbling across a transmission from aliens.

The researchers, whose study will appear in an upcoming edition of the International Journal of Astrobiology, focused their work on the expected eavesdropping capabilities of the Square-Kilometer Telescope, a radio telescope slated to be completed by 2023.

Two of each Earth species shall board: several liberal pairs of humans (plus some older single people for good measure); 5 pair of pets; 7 pair of livestock species; 7 pair of livestock birds (such as chickens and turkeys--we gotta have Thanksgiving on the mothership!); 1 pair each of wildlife species--AND NO PESTS! Keep the bed bugs, mosquitoes, and other pests on Earth to harass the fascists.

They sent out an ark fleet. Sadly.

We've fucked up one planet already

because of it, there's a lot of wild theories out there. I find them fascinating actually, makes life interesting to explore possibilities. Especially that not only are we fucking up this planet, we might just be out of the loop in what is going on in the rest of the Galaxy.

...is able to exist on either (or all) of those planets, then there's no reason to doubt that life is common, and not rare, in the universe.

Get the rocket ready for them now!

TRAPPIST-1.

I could get some good stories out of it. I imagine.

As to other lifeforms contacting us? I imagine they're keeping an eye on us, watching to see what we do. The day we invent a viable FTL drive, they'll probably launch a world-killer asteroid at us and end the threat.

Hell, you can even do it with stuff you can buy off the shelf at the local camera store.

Astronomers there have claimed to have found a habitable planet just 40 light years away.

They called it Earth.

thanks

we needed rockets for that and to grow food for the 60 bil we'd resurrect

Well hell let's hop on the shuttle and check em out!
