science π Universe's biggest map is here for everyone to explore
Scientists have released the largest 2D map of the Universe, featuring nearly four billion celestial objects. This massive map was created by stitching together hundreds of thousands of telescope images over 13 years. It comes from the DESI Legacy Imaging Surveys, which supports the study of cosmic expansion. The 5.6 trillion-pixel map covers about 75 per cent of the sky in visible and near-infrared light. Astronomers and citizen scientists can now use this data to study dark matter and the Universe's fate.
