Astronomers announce 7 earth size exoplanets around dwarf sun

Astronomers have never seen anything like this before: Seven Earth-size alien worlds orbit the same tiny, dim star, and all of them may be capable of supporting life as we know it, a new study reports.
"Looking for life elsewhere, this system is probably our best bet as of today," study co-author Brice-Olivier Demory, a professor at the Center for Space and Habitability at the University of Bern in Switzerland, said in a statement.
The exoplanets circle the star TRAPPIST-1, which lies just 39 light-years from Earth — a mere stone's throw in the cosmic scheme of things. So speculation about the alien worlds' life-hosting potential should soon be informed by hard data, study team members said.
"We can expect that, within a few years, we will know a lot more about these planets, and with hope, if there is life there, [we will know] within a decade," co-author Amaury Triaud, of the Institute of Astronomy at the University of Cambridge in England, told reporters on Tuesday (Feb. 21).

TRAPPIST-1 is an ultracool dwarf star that's only slightly larger than the planet Jupiter and about 2,000 times dimmer than the sun.
The research team, led by Michaël Gillon of the University of Liège in Belgium, originally studied the star using the TRAnsiting Planets and PlanetesImals Small Telescope (TRAPPIST), an instrument at the La Silla Observatory in Chile. (This explains the star's common name; the object is also known as 2MASS J23062928-0502285.)

I bet they won't know shite in 10 years.

So we have 39 years to destroy all seven or it's curtains for mankind? This is like Michael Bay level drama.

This is pretty big news and 39 light years really isn't that far away in relation to most of space

I want to live on that green one

I don't believe in Astronomy, let me guess, these 7 planets are aligned a certain way and it's going to tell me about my love life?
These so-called scientists need to grow up and stop believing in nonsense.

Don't sell it short, from the original story:
"TRAPPIST-1 is an ultracool dwarf star"

So other planets stars, our moon, and our sun are fake?

So...like you don't believe in stars and planets?

What, don't be ridiculous. The great Astrologers of our time have all proven these things are real.

If they do know shite and find something, the general public sure as hell won't find out about it.

Here are some details from NASA's conference:
1) Spitzer detects 7 earth size planets around the TRAPPIST-1 Star System
2) 40 light years away
3) 3 planets are in the right zone for liquid water
4) Have measured the masses and radi of earth-size planets
5) Can look at atmosphere and bio-signatures
6) Planets are close to each other, you would see them similarly as you would see Earth’s moon.
7) Planets are so close, they interact gravitationally on each other.
8) Trappist-1e is very close in size to earth. It receives a similar amount of light as Earth does.
9) Trappist-1f (MIGHT) be water-rich and similar in size as earth (NASA just said currently no detection of water). Receives about as much light as Mars.
10)Trappist-1g is largest in the system, 13% larger radius than Earth. Receives about as much light as Mars and the Asteroid belt.

It's a joke. He's pretending to mistake Astronomy for Astrology.

They didn't mention that its atmosphere is made almost entirely of rabid weasels.
The universe is a weird place.
