James Webb Space Telescope Flight Instruments and Primary Mirror Segments Ready for Assembly

The amazing mirrors that will fly aboard NASA’s James Webb Space Telescope will allow the James Webb Space Telescope to see farther away and further back in time to detect the light from the very first and most distant stars and galaxies. In this photo, an engineer’s crystal clear reflection is seen on the [...]

The Majestic Realm of a Forgotten World: The Alluring Mysteries of Uranus

A false-color photograph of Uranus, its rings, and 10 of its moons, taken by the Hubble Space Telescope’s Near Infrared Camera and Multi-Object Spectrometer in near-infrared wavelengths. As seen in this photo, there’s so much more to see on Uranus than meets the eye. This enigmatic world deserves a dedicated space mission to be [...]

Probing the Dawn of Time: Hubble Frontier Fields Releases First Views of Distant, Previously Unseen Galaxies

A long-exposure image of galaxy cluster Abell 2744, obtained by the Hubble Space Telescope, as part of the Hubble Frontier Fields program. The long blue streaks surrounding the cluster in the image come from the light of much more distant galaxies, located as far as 13 billion light-years away behind the cluster. Image Credit: [...]
