It's a hot planet.
What the hot rocky exoplanet TRAPPIST-1 b could look like ) Light has been detected from a planet similar to Earth – but it has no atmosphere. Nasa’s infrared Spitzer Space Telescope discovered several rocky exoplanets orbiting a star known as TRAPPIST-1. But now, thanks to the James Webb Space Telescope, also known as the Webb, one of the rocky exoplanets orbiting the star has had its temperature measured.
Dr Thomas Greene, a Nasa astrophysicist and lead author said: ‘These observations take advantage of Webb’s mid-infrared capability. ‘No previous telescopes have had the sensitivity to measure such dim mid-infrared light.’ The find is an important step in determining whether planets orbiting small active stars like TRAPPIST-1 can house atmospheres needed to support life.
