The Hubble Space Telescope (HST) is a space telescope that was launched into low earth orbit in 1990, and remains in operation today. With a 2.4 metre (7.9 ft) mirror, HubbleÌ_Ì_åÈs four main instruments observe in the near ultraviolet, visible, and near infrared spectra. The telescope is named after the astronomer Edwin Hubble. HubbleÌ_Ì_åÈs orbit outside the distortion of EarthÌ_Ì_åÈs atmosphere allows it to take extremely high-resolution images with negligible background light. Hubble has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics, such as accurately determining the rate of expansion of the universe.
