According to the , quoted by Space, the observations of the James Webb Space Telescope indicate that there is a single extrasolar planet near the Earth.
This planet is located at a distance of 100 light years from Earth and is covered in a thick layer of vapor. The size of the mentioned planet, which is called GJ9827d, is twice the size of the Earth and its volume is three times that of the terrestrial planet. The atmosphere of the planet is also completely composed of water vapor.
Ishan Raul, one of the researchers of the study, says: This is the first time we observe something like this. It seems that most of this planet is made up of hot water vapor and that is why we call it a hot world. More precisely, this planet cannot sustain life similar to what exists on Earth.
Astronomers have long estimated that hot planets like this one exist, but this is the first time that such a planet has been observed outside the solar system.
A group of researchers from the “Trottier Exoplanet Research Institute” at the University of Montreal discovered the nature of GJ9827 d’s heat using a method called “transmission spectroscopy”. This method is based on the fact that the elements and chemical substances that make them absorb and emit the electromagnetic properties of the wavelength of light. When light from a star shines into a planet’s atmosphere, the elements in it absorb certain wavelengths and create gaps in the light spectrum. These gaps are traces of certain elements and molecules in that atmosphere.
GJ9827 d was first discovered by the Kepler telescope in 2017. This extrasolar planet is located at a distance of 8.4 million kilometers from its host star, which is 6% of the distance from Earth to the Sun. Such a small distance means that the orbit of the planet around its star is equivalent to 6 Earth days. This is the third planet outside the solar system that orbits the mentioned star.
