Space telescope

Space telescopes can also observe dim objects during the daytime, and they avoid light pollution which ground-based observatories encounter.

In 1946, American theoretical astrophysicist Lyman Spitzer, "father of Hubble" proposed to put a telescope in space.

[3] This was launched due to many efforts by Nancy Grace Roman, "mother of Hubble", who was the first Chief of Astronomy and first female executive at NASA.

Performing astronomy from ground-based observatories on Earth is limited by the filtering and distortion of electromagnetic radiation (scintillation or twinkling) due to the atmosphere.

Satellites have been launched and operated by NASA, ISRO, ESA, CNSA, JAXA and the Soviet space program (later succeeded by Roscosmos of Russia).
