The Hubble Space Telescope is celebrating its 35th anniversary in space today .

Launched in 1990 by NASA and operated jointly with the European Space Agency .

The observatory has had a hand in many of the most crucial astronomical discoveries of the past four decades .

Hubble pioneered the study of exoplanetary atmospheres, and is still vital for keeping track of goings-on in the atmospheres of the outer giant planets of our solar system.

Hubble is the only general-purpose ultraviolet facility currently in operation.

The telescope's ultraviolet vision is precious — ultraviolet astronomy can only be conducted above Earth ’s absorbing ozone.

The true successor to Hubble , able to operate in both ultraviolet and optical light with an eight-meter mirror, will not launch until the 2040s at the earliest.
