In a recent observation, astronomers found that an exoplanet known as GJ 1252 b, which was discovered in 2020, might have very little or almost no atmosphere. Astronomers used the now-retired Spitzer Space Telescope to measure the exoplanet’s infrared radiation.
As per scientists’ observations, GJ 1252 b’s dayside temperatures went beyond 1,228˚C, but it has a surface pressure of less than 10 bar (Earth’s surface pressure is approximately 1 bar). Due to low surface pressure and very high temperatures, scientists believe that the exoplanet may have very little or no atmosphere at all.
