In The Heart Of Cygnus, NASA’s Fermi Reveals A Cosmic-ray Cocoon
The constellation Cygnus, now visible in the western sky as twilight deepens after sunset, hosts one of our galaxy’s richest-known stellar construction zones.
Astronomers viewing the region at visible wavelengths see only hints of this spectacular activity thanks to a veil of nearby dust clouds forming the Great Rift, a dark lane that splits the Milky Way, a faint band of light marking our galaxy’s central plane.
