Description: A comparison between the M51 image taken using the PFC on the WHT and an image of the same object from Hubble Space Telescope Heritage Project. M51 galaxy, known as The Whirlpool Galaxy, is a bright spiral galaxy fairly close to us (7.5 Megaparsecs = 25 million light years). To the north of M51, at the bottom of the picture, is a companion galaxy which is being disrupted by the gravitational tidal forces of the main galaxy.

Description: NGC 6946 (Arp 29) is a face-on SAB(rs)cd galaxy in the constellation Cygnus. This classification refers to the presence of a small core with multiple well-defined arms (cd), with a poorly-developed bar across the middle (AB) and an inner confused ring (rs). Nearly twenty million light years from Earth, it is over seventy thousand light years across. PDF version: https://www.ing.iac.es/PR/dissemination/edgeoff.pdf

Description: The Herschel Deep Field is a 7x7 arcminute patch of sky in the constellation of Pisces which has been observed with the 4.2-m William Herschel telescope for a total of about 70 hours. The picture shown here is a rue colour composite of images taken at ultra-violet, blue and red wavelengths. Most of the objects are distant galaxies, although the very brightest ones are stars. This is one of the deepest images ever taken from the ground and shows images almost as faint as the famous Hubble Deep Field but over a 10 times bigger area of sky. An analysis of the colours of these galaxies has shown that many are at such large distances and look-back times that the epoch of galaxy formation must have been at even higher redshifts than was previously thought. This is a true-colour image composed from the U, B and R frames and acquired with the Prime Focus camera on the WHT. Limiting magnitudes are U=26.8 (34 hours), B=27.9 (28 hours) and R=26.3 (8 hours).

Description: This is galaxy cluster Abell 1656 (the large elliptical galaxy in the middle is NGC4874). Astronomers from the University of Durham found a cosmic flow of galaxies across one billion light years of the Universe by studying clusters like this one.
