The recently discovered outer solar system, WASP-121b, has been found to have an outer atmosphere, such as the Earth's stratosphere.
The stratosphere, like Earth, forms the outer layer of the planet's atmosphere. The discovery was published in the science journal Nature.
WASP-121b is one of the hot, extraterrestrial planets classified under the name 'Hot Jupiter'.
As the name suggests, the temperature of the planet is very hot and the size is big.
WASP-121b is 880 light years away from Earth, but its size is large and easy to study.
From a theoretical model, the presence or absence of a stratosphere appears to be a common feature of extreme solar eclipses, suggesting important discoveries related to atmospheric physics and chemistry.
