Since its 1990 launch, the Hubble Space Telescope has changed our fundamental understanding of the universe. Why a telescope in space? How does the observatory work? Who is the team behind Hubble? Throughout the history of science, revolutionary instruments propel our understanding with their landmark discoveries.
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation.
The telescope has beamed hundreds of thousands of celestial images back to Earth during its time in space. Hubble is a Cassegrain reflector telescope. Light from celestial objects travels down a tube, is collected by a bowl-like, inwardly curved primary mirror and reflected toward a smaller, dome-shaped, outwardly curved secondary mirror.
Hubble Space Telescope (HST), the first sophisticated optical observatory placed into orbit around Earth. Earth’s atmosphere obscures ground-based astronomers’ view of celestial objects by absorbing or distorting light rays from them.
The Hubble Space Telescope is a large space telescope orbiting Earth. The telescope captures pictures of our universe to help scientists on Earth understand it better. Small yet mighty!
