This is a map of the cube of spacetime covered in the new survey, showing the distance to the galaxies in billions of light years. The positions of the 4,000 galaxies appear as circles. The colours represent the degree of redshift seen, with the bluer circles indicating galaxies nearer to the Earth, and so less redshifted. Green, yellow, orange and red circles indicate successively higher redshifts, and galaxies that are progressively further away from the Earth. Credit: D. Sobral

A new Uni of Sussex study has cleared the air on what lies behind hot dust visible in the distant universe. Researchers found that the glow of heated dust reaching our planet is frequently due to 3 or 4 galaxies instead of a single one, as scientists had previously assumed. The study applied a statistical method to data from the Herschel Space Observatory to solve one of astrophysics’ great conundrums.

Dr Jillian Scudder said: “This is a really interesting result because when we assumed that one galaxy had to be responsible for all of the dust emission, it implied that the galaxy must be forming a tremendous number o...
