The final frontier of the Frontier Fields

Above: The last of the Hubble Space Telescope’s Frontier Fields — Abell 370 combined with Abell 370 (seen in 2009)

With the final observation of the distant galaxy cluster Abell 370 — some five billion light-years away — the Frontier Fields program came to an end.

Abell 370 is one of the very first galaxy clusters in which astronomers observed the phenomenon of gravitational lensing, the warping of spacetime by the cluster’s gravitational field that distorts the light from galaxies lying far behind it. This manifests as arcs and streaks in the picture, which are the stretched images of background galaxies.

Combined image: This image of Abell 370 was released in 2009. Compared to the new image, which contains more observation time, less structures are visible and faint objects have disappeared — the new image has increased the depth of the image dramatically, clearly showing the benefit of additional observation time. A direct comparison between both images can be seen here.

The first Hubble Space Telescope's observations in the new BUFFALO project have been published. Its goal is to shed light on the evolution of the first galaxies of the universe, also to establish the most interesting observation targets for the James Webb space telescope. The Abell 370 galaxy cluster is the first to be studied for this new survey together with a series of galaxies seen through gravitational lenses.

Sono state pubblicate le prime osservazioni del telescopio spaziale Hubble nel nuovo progetto BUFFALO, che ha lo scopo di far luce sull'evoluzione delle prime galassie dell'universo, anche per stabilire gli obiettivi più interessanti per le osservazioni del telescopio spaziale James Webb. L'ammasso galattico Abell 370 è il primo a essere oggetto di studio per questa nuova indagine assieme a una serie di galassie viste attraverso lenti gravitazionali.
