Keep Looking, What Do You See?

Short answer: The Hubble Space Telescope, a NASA project with the European Space Agency, was launched aboard Space Shuttle Discovery on April 24, 1990. A flaw in its main mirror was corrected by astronauts in 1993, and five servicing missions kept it working.

Orbiting above the atmosphere, it takes sharp images free of atmospheric blur. Its observations helped pin down the age of the universe at about 13.8 billion years, supported the discovery of the universe's accelerating expansion and dark energy, and produced views of distant galaxies and nebulae. The footage shows Hubble in orbit and its images, with the presenter.
