Peering ever further back in space and time, the Hubble Space Telescope has glimpsed the largest known group of the faintest and youngest primordial galaxies ever—over 250—some of which are […]

Hubble Observes the 'Ghost Light' of Orphaned Stars Inside Galaxy Cluster

The massive galaxy cluster Abell 2744 takes on a ghostly look in this view by the Hubble Space Telescope, where the total starlight from the cluster has been artificially colored blue. This reveals that not all the starlight is contained within the galaxies, which appear as bright blue-white blobs in the image. A […]

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 […]
