NASA scientists want to make Pluto a planet again
Sad About Pluto? How about 110 Planets in the Solar System Instead? http://www.universetoday.com/133525/sad ... m-instead/


In contrast to our sun, the TRAPPIST-1 star – classified as an ultra-cool dwarf – is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun. The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth's sky.
The planets may also be tidally locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong winds blowing from the day side to the night side, and extreme temperature changes.

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 is (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.
On dirait que non (drumpf doit signer mais ça semble être une formalité, pas de mexicains dans l'espace).صلاح الدين آكلى لحوم البش a écrit :Profitez-en, quand Donald aura sucré 80 % des crédits de ces connards de climato-alarmistes de la NASA ça sera terminé tout ça.
