## Resource

A mysterious glow from the centre of the Milky Way has scientists intrigued. Astrophysicist Geraint Lewis explains how this gamma-ray excess, first detected in 2009, could be evidence of dark matter particles interacting deep in our galaxy. With dark matter believed to make up a vast, invisible halo that holds galaxies together, uncovering the source of this glow may bring us closer to understanding what the universe is really made of. www.geraintflewis.com/ Linkedin: geraint-lewis-4a499b1
