Looking Beyond: NASA's Frontier Fields Possibly Finds One of the Youngest Galaxies in the Early Universe

This image of the galaxy cluster Abell 2744 was obtained with NASA’s Hubble Space Telescope, as part of the Frontier Fields program, designed to push the limits of how far we can see into the early universe. The zoomed image shows the region around the galaxy Abell2744_Y1, one of the most distant galaxy candidates [...]

Seventeen years ago this week, NASA launched its second shuttle Servicing Mission (SM-2) to the Hubble Space Telescope (HST). The $1.5 billion observatory has earned itself a well-deserved reputation as one of the most successful space-based instruments ever launched. [...]

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 [...]

NASA's Hubble Helps Solve Mystery of Ultra-Compact, Burned-Out Galaxies

Astronomers using NASA’s Hubble Space Telescope and Europe’s Herschel Space Observatory have pieced together the evolutionary sequence of compact elliptical galaxies that erupted and burned out early in [...]

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: [...]
