A bright spiral galaxy of the northern sky, Messier 63 is nearby, about 30 million light-years distant toward the loyal constellation Canes Venatici. Also cataloged as NGC 5055, the majestic island universe is nearly 100,000 light-years across, about the size of our own Milky Way.

The Race to Reveal Our Universe
9.05.2000

A race is underway to understand our universe through background radiation produced during its infancy. Observationally, increasingly accurate balloon experiments are pressing to beat future space-faring satellites to definitive measurements of universe-determining spot characteristics of the cosmic microwave background (CMB) radiation.
