TRAPPIST-1 remains to be one of the most likely star system suitable for sustaining life as new discoveries related to star system have become a common topic in news related to space exploration. For a while now, scientists have speculated that some of the planets in the star system may have been able to hold onto an atmosphere for more than one billion years at a time which is essential to sustain life. If one of TRAPPIST-1’s planet has an atmosphere, then it’s likely that it is home to some sort of alien life form.
The recent implications were raised by a team of scientists from Harvard and Princeton who published a paper discussing the probability of life in one of the planets in the star system after an analysis of the atmosphere of these planets.
The academics wrote, ‘The presence of an atmosphere over sufficiently long timescales is widely perceived as one of the most prominent criteria associated with planetary surface habitability.”
‘We conclude that the outer planets of the TRAPPIST-1 system are capable of retaining their atmospheres over billion-year timescales.’
While Planets often lose their water due to radioactive solar wind by their star, the researchers revealed that some of the planets in the star system might have enough protection from solar wind to protect its atmosphere. Moreover, the research suggests that if such atmosphere exists, then the planets are capable of keeping them for at least one billion years. However, the scientists aren’t sure if the time period is long enough for life forms to evolve.
