The Frontier Fields


THE WORLD is charged with the grandeur of God.
It will flame out, like shining from shook foil;
It gathers to a greatness, like the ooze of oil
-- Gerard Manley Hopkins 1918

Released as the first "Frontier Fields" view from NASA's Hubble Space Telescope, the new images mark the deepest-ever observations of a cluster of galaxies. The photos center on Abell 2744, a group of several hundred galaxies found 3.5 billion light-years away from Earth.

Using Director's Discretionary (DD) observing time, HST is undertaking a revolutionary deep field observing program to peer deeper into the Universe than ever before and provide a first glimpse of JWST's universe.

These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. Using both the Wide Field Camera 3 and Advanced Camera for Surveys in parallel, HST will produce the deepest observations of clusters and their lensed galaxies ever obtained, and the second-deepest observations of blank fields (located near the clusters). These images will reveal distant galaxy populations ~10-100 times fainter than any previously observed, improve our statistical understanding of galaxies during the epoch of reionization, and provide unprecedented measurements of the dark matter within massive clusters.

The first time I saw that picture I heard, "What is man that thou art mindful of him?" in my head. Corny I guess. But really, what else describes the moment?

The next thought I had was, "I am nothing."
