New News, Jakarta – NASA’s James Webb Telescope recently detected the temperature of an Earth-like planet known as TRAPPIST-1b. Unfortunately, this planet is too hot and has no atmosphere.
Previously, NASA’s Spitzer telescope helped discover seven rocky planets orbiting around TRAPPIST-1. Now, the more powerful James Webb Telescope (JWST) measured the temperature of one of these planets, TRAPPIST-1b, in research published in the journal Nature.
Astronomers use JWST’s mid-infrared camera, called MIRI, to look for planetary thermal emissions. They found that TRAPPIST-1b is extremely hot, at around 232 degrees Celsius, and likely has no atmosphere.
This discovery is the first achievement made by JWST and demonstrates the success of this telescope since its launch. “This is the first detection of a form of light emitted by an exoplanet that is as small and cool as a rocky planet in our own solar system,” said NASA officials. Live Scinence.
However, TRAPPIST-1b cannot be used as a human habitation. This planet is too far away, located about 378 trillion kilometers from Earth and orbiting a star that is smaller and redder than our Sun.

“There are ten times more such stars in the Milky Way than there are stars like our Sun, and twice as likely to have rocky planets like our Sun,” said Thomas Greene, a NASA astrophysicist and lead author of the study.
Nonetheless, planets around M-type stars are attractive targets for astronomers looking for habitable planets. However, this type of star is also more active than our Sun, often releasing high-energy rays that can be detrimental to life.
This discovery indicates that JWST is capable of measuring the temperature and atmosphere of other planets and will continue to explore other planets outside our solar system. “This is an important step in the exoplanet discovery story,” said Pierre-Olivier Lagage, one of the MIRI developers.
