New Delhi, Mar 28 (PTI) Scientists used National Aeronautics and Space Administration's (NASA's) James Webb Space Telescope (JWST) to measure the temperature of an exoplanet TRAPPIST-1 b of an M-dwarf system 40 light years from Earth.

The measurement was close to 225 degrees Celsius and was done by detecting the planet's thermal emissions, recorded by the infrared sensor of the Webb telescope, Mid-Infrared Instrument (MIRI).

The international team of scientists involved in the study are also trying to determine if the exoplanet has an atmosphere or not, they said. The study is published in the journal Nature.
