There are stars forming 1,000 light years away in Serpens Cauda, which means they actually were forming at the turn of 1,000 AD as the light took 1,000 years to get to Earth. The camera used, HAWK-I, had to be extra sensitive as the light emitted was near-infrared, and the wavelength is too long for the naked eye to pick up. The camera was just commissioned in Chile and demonstrates its impressive capabilities by picking up these newborn stars emerging from a molecular cloud.
