A Death and a Birth

Deep Sky Object

Messier 35 and its faint neighbor NGC 2158, a pairing of a nearby bright cluster and a distant compact one in the same field. Northern Hemisphere favored.

Featured Star

Castor (α Gem), a white main-sequence pair in Gemini, 51.5 light-years away. Castor, the mortal twin, hiding five more stars behind one point of light.
