The Frontier Fields is an ambitious, collaborative, multiyear program conducted by NASA's Great Observatories—with a boost from natural "zoom lenses" found in space— to look more deeply into the universe than ever before. Abell 2744 is the first of a set of Frontier Fields. The immense gravity in this foreground galaxy cluster warps space to brighten and magnify images of far-more-distant background galaxies as they looked over 12 billion years ago, not long after the big bang.

The Southern Pinwheel lies 15 million light-years away in the constellation Hydra. The Hubble photograph captures thousands of star clusters, hundreds of thousands of individual stars, and "ghosts" of dead stars called supernova remnants. The vibrant magentas and blues reveal the galaxy is ablaze with star formation.

The Hubble mosaic in infrared-light unveils a collection of carved knots of gas and dust in a small portion of the Monkey Head Nebula. The nebula is a star-forming region located 6,400 light-years away that hosts dusky dust clouds silhouetted against glowing gas.

Hubble measurements of Jupiter's monster storm confirm it is significantly downsizing; the diameter getting smaller by about 580 miles per year. Astronomers have followed this reducing in size since the 1930s.

Hubble astronomers have assembled this comprehensive picture of the evolving universe with separate exposures taken in visible, near-infrared, and ultraviolet light from 2002 to 2012. By observing at these wavelengths, researchers get a direct look at which galaxies are forming stars and where the stars are forming within those galaxies.
