- NASA plans to fix a glitch that has stopped the Hubble space telescope from being used for science work for more than a month.
- The Hubble Space Telescope was launched into low Earth orbit in 1990 and remains in operation.
- The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory (1991–2000), the Chandra X-ray Observatory, and the Spitzer Space Telescope (2003–2020).
- Hubble and its four main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum.
- Hubble's orbit outside the distortion of atmosphere of Earth allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes.
- It has recorded some of the most detailed visible light images, allowing a deep view into space.
- Many Hubble observations have led to breakthroughs in astrophysics, such as determining the rate of expansion of the universe.
