Ever since the bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful of a new solar system bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful weeks ago, scientists have been discussing bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful planets in the system could contain bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful . Scientists called the system "TRAPPIST-1". It contains a small sun and seven Earth- bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful planets. It is very bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful to our own solar system. NASA scientist Michael Gillon said three of the seven TRAPPIST-1 planets receive as much bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful from its sun as Venus, Earth and Mars receive from our Sun. He said this provides the right bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful for life to exist. TRAPPIST-1 is in a star system called Aquarius. It is nearly 40 bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful -years away from the Earth. Its sun is smaller than our Sun and has just 1/1000th of its bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful , but that could be enough to support life. Michael Gillon explained that you could see the bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful six planets in the sky if you were on one of the TRAPPIST-1 planets. A bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful planet could look bigger than our bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful of our Moon. Mr Gillon said: "If you were on the bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful of one of these planets, you would have a bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful view of the other planets. You wouldn't see them like we see Venus or Mars, like bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful of light. You would see them really as we see the Moon. You would see the bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful on these worlds." Astronomer Dr Jessie Christiansen said life exists everywhere, "such as bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful that survives in 130-degree caves, or things at the bottom of the bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful where there's no light". She said it could be bacteria brightness discovery dots environment heat life light neighbouring ocean other possible several similar sized structures surface view whether wonderful for life to exist on some of these planets.
