Some Of The TRAPPIST-1 Planets Could Hold On To An Atmosphere For Billions Of Years

29 December 2017

There is a lot we don’t know about how life started on Earth or how it may have started elsewhere in the Universe, but there are certain things we think are crucial. A planet with an atmosphere is one of these requirements, so researchers have worked out the chance of this happening in the famous seven-planet system TRAPPIST-1.

Some of TRAPPIST-1’s planets could have life-friendly atmospheres: here.

Some TRAPPIST-1 planets may be water worlds. Water is a sign of possible life. Too much water may prevent us from finding it. By Laurel Hamers, 5:53pm, March 19, 2018.

For a number of years, two ‘boxes’ in the Canary Islands and Chile have been scouring the skies for exoplanets that orbit bright stars. PhD candidate Geert Jan Talens helped develop these ‘MASCARA’ telescopes and has made the first discoveries with them. Together with him, we answer the main questions about Leiden University’s research stations: here.

POTENTIALLY HABITABLE ‘SUPER EARTH’ FOUND NASA’s Transiting Exoplanet Survey Satellite has spotted some intriguing new exoplanets only 31 light-years away from Earth. GJ 357 d, a super-Earth that is 6.1 times the Earth’s mass, is the most intriguing because it orbits a star at a distance where the temperature might support liquid water on the surface. [CNN]
