Scientists have discovered an enormous ‘bubble’ in space.
The sphere-shaped void is baffling astronomers as they are unsure what it is and how it was made.
The ‘bubble’ stretches across almost 500 light years across.
The ‘bubble’ was found using powerful telescopes by the team at the Institute for Theory and Computation (ITC).
What is a lightyear?
A light-year is a measurement of the distance that light can travel in one year.
The team discovered the ‘bubble’ when they were studying ground-breaking 3D maps of the shapes and sizes of nearby molecular clouds – enormous clumps of gas and space dust.
