Witnessing The Formation Of Distant Galaxies

UK astronomers have produced the most sensitive infrared map of the distant Universe ever undertaken. Combining data over a period of three years, they have produced an image containing over 100,000 galaxies over an area four times the size of the full Moon. Some of the first results from this project will be presented by Dr Sebastien Foucaud from the University of Nottingham on Friday 4th April at the RAS National Astronomy Meeting in Belfast.

Due to the finite speed of light, these observations allow astronomers to look back in time over 10 billion years, producing images of galaxies in the Universe's infancy. The image is so large and so deep that thousands of galaxies can be studied at these early epochs for the first time. By observing in the infrared, astronomers can now peer further back in time, since light from the most distant galaxies is shifted towards redder wavelengths as it travels through the expanding Universe.
