Hubble Space Telescope
Hubble Space Telescope discovered first example of atmosphere around an exoplanet in 2001. Hubble spotted a hydrogen atmosphere around the exoplanet with the unofficial name of Osiris. The exoplanet’s official name is HD 209458b, and it is a “hot Jupiter” body, because its atmosphere temperature is 2150 degrees Fahrenheit. Located in the constellation Pegasus, it is 150 light years away from us. It is 220 times the mass of the earth. Children could learn more at: Osiris.
