Nasa celebrates Hubble's work

NASA has marked the silver anniversary of the Hubble Space Telescope with fireworks, of a celestial kind, conveyed by the orbiting observatory itself. To commemorate Hubble's launch on April 24, 1990, NASA selected a picture of a stellar nursery located about 20,000 light-years away in the constellation Carina.

With a 2.4-meter (7.9ft) mirror, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared spectra.

Hubble's orbit outside of Earth's atmosphere allows it to take extremely high-resolution images with negligible background light.
