This view is a combination of images from ALMA and the Very Large Telescope. The central object is a very distant galaxy, labelled BDF 3299, which is seen when the Universe was less than 800 million years old. The bright red cloud just to the lower left is the ALMA detection of a vast cloud of material that is in the process of assembling the very young galaxy.
