NASA have discovered by accident the larget spiral galaxy in the universe. It’s called NGC 6872 and it’s so big five Milky Ways could fit in it. The galaxy is 212 milion light years away and researchers spottedit while looking for star-forming regions nearby.
The Huffington Post reports:
Instead they found a huge amount of ultra-violet light from young stars – which revealed the true scale of the galaxy itself. It is thought after further observations that the wave of new star formation was kick-started by the collision with IC 4970.
