Data from NASA's James Webb Telescope shows that the exoplanet TRAPPIST-1 c has either zero or very little atmosphere and the possibility of life is slim.
The research team observed TRAPPIST-1 c on four separate occasions as it orbited around a star to determine how much atmosphere it has.
If a planet has any atmosphere at all, it will redistribute heat from the dayside to the nightside, causing the dayside temperature to be lower than it would be without an atmosphere, NASA said. Zieba said the team’s research is consistent with the planet being a bare rock, with no atmosphere or the planet having less CO2 atmosphere than Earth or even Mars with no cloud.
The absence of any thick atmosphere suggests the exoplanet could have possibly formed with relatively little water, NASA said.
