Astronomers led by David Sobral and Jorryt Matthee, of the Universities of Lancaster in the UK and Leiden in the Netherlands have discovered giant halos around early Milky Way type galaxies, made of photons (elementary particles of light) that have struggled to escape them. The team reports its findings in the journal Monthly Notices of the Royal Astronomical Society.
