SOFIA Telescope:

SOFIA stands for Stratospheric Observatory for Infrared Astronomy. It is a 2.7-meter infrared telescope sitting inside a Boeing 747SP airplane. The plane flies at an altitude of 38,000-45,000 feet above the surface of earth. It is the world’s largest flying telescope. The telescope has made important discoveries like presence of water on Moon in Clavius Crater (2020). It also discovered helium hydride; the first molecule formed in the Universe almost 14 billion years ago. NASA has decided to shut down the SOFIA Telescope.
