Hubble Frontier Field Abell 2744
This long-exposure Hubble Space Telescope image of massive galaxy cluster Abell 2744 is the deepest ever made of any cluster of galaxies. It shows some of the faintest and youngest galaxies ever detected in space. [See full story.]
Hubble Frontier Field Abell 2744-Parallel
This long-exposure Hubble Space Telescope image of massive galaxy cluster Abell 2744 is the deepest ever made of any cluster of galaxies. It shows some of the faintest and youngest galaxies ever detected in space. Abell 2744, located in the constellation Sculptor, appears in the foreground of this image. It contains several hundred galaxies as they looked 3.5 billion years ago. The immense gravity in Abell 2744 acts as a gravitational lens to warp space and brighten and magnify images of nearly 3,000 distant background galaxies. [See full story.]
Will NASA's Ailing Planet-Hunting Kepler Spacecraft Get New Mission?

Ultra-Precise New Measurement of Universe's Scale
An artist's concept of the latest, highly accurate measurement of the universe from the Baryon Oscillation Spectroscopic Survey. The spheres show the current size of the "baryon acoustic oscillations" (BAOs) from the early universe, which have helped to set the distribution of galaxies that we see in the universe today. BAOs can be used as a "standard ruler" (white line) to measure the distances to all the galaxies in the universe. [See full story.]
