Temperature of a rocky exoplanet measured

Summary by Ground News

Researchers used the NASA/ESA/CSA James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 230�C) This is the first detection of any form of light emitted by an exoplanets as small and as cool as the rocky planets in our own solar system.

Webb measures temperature of rocky exoplanet for first time

The James Webb Space Telescope has measured the temperature of a rocky exoplanet for the first time, finding that a "cousin" of Earth most likely lacks an atmosphere, researchers said Monday.When the Trappist-1 system was discovered in 2017, astronomers were excited at the prospect that some of its seven rocky planets -- which are roughly similar to Earth in size and mass -- could be habitable.Just 40 light years from Earth, the planets orbit mu…

Temperature of a rocky exoplanet measured

An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly 450 degrees Fahrenheit) and suggests that it has…
