NASA Has Detected The Water Vapor In The Atmosphere of Exoplanet: TOI-674B

Water vapor is detected in the atmosphere of an exoplanet. This exoplanet is known as TOI-674B. This exoplanet was discovered by TESS in 2018. Scientists called it Super Neptune because it is bigger than our Neptune. The sensitive astronomical instruments detected this exoplanet when it passed in front of its host star. An international team of scientists studied the atmosphere of this super Neptune. They combined the data from the TESS and the Hubble Space Telescope. It has a thin atmosphere which makes its investigation easier.

Exoplanets are the ones that orbit a star other than our Sun. The Hubble telescope measured its spectrum. It is located in the constellation called Antila. You can spot it in the southern celestial hemisphere. It is about 150 light-years away from the Earth. The mass of this exoplanet is 23 times the mass of Earth. It is close to its host star zipping around a red dwarf about every two days. The host star is cooler and less than half the size of our Sun. NASA says this planet will further be analyzed by the James Webb Space Telescope.

The amount of water can tell us that it was formed inside or outside the water ice line. But right now, scientists are unable to calculate the amount of water. Thought the atmosphere of TOI-674B is much easier to study than the other exoplanets. The discovery of planets in size-class between Neptune and Jupiter is extremely rare. So, this exoplanet is very important to us. Many questions remain to answer, like how much water vapor its atmosphere hold. Does this indicate the presence of life? The Webb promises a golden age study of exoplanet’s atmosphere to answer all such questions. We’ll bring to you the details of the James Webb Telescope in our future articles.
