description Infrared Space Observatory Overview
The Infrared Space Observatory (ISO) was a European Space Agency space telescope launched by an Ariane 4 rocket in November 1995. It operated in a highly elliptical orbit until May 1998, conducting infrared imaging, photometry, and spectroscopy. The observatory's instruments allowed astronomers to study cool and hidden regions of the universe, such as star-forming clouds and distant galaxies, which are difficult to observe in visible light. It carried four main scientific instruments, including an infrared camera and a long-wavelength spectrometer.

When did the Infrared Space Observatory operate?
ISO operated from its launch in November 1995 until May 1998. During that period it worked in a highly elliptical orbit and conducted infrared observations.
What did ISO observe?
The observatory performed infrared imaging, photometry, and spectroscopy. These techniques allowed astronomers to study cool dust, star-forming regions, and other objects that are difficult to examine using only visible light.
How was the Infrared Space Observatory launched?
The European Space Agency launched ISO on an Ariane 4 rocket in November 1995. The telescope was then placed into a highly elliptical Earth orbit for its observing mission.
