How to Observe Gemini, the Heavenly Twin Constellation
Gemini is a constellation high in the winter sky and can be easily seen this week after dark.
If you head outside around 10:30 p.m. local time this week and look straight up, you’ll be looking directly at Gemini, the Twin Brothers.
The heads of the Gemini twins are the bright stars Pollux (yellowish) and Castor (white; a bit dimmer than Pollux). According to Greek mythology, the twins were the sons of Zeus and Leda and brothers of Helen of Troy.
