Inhabitant of the Cosmic Ocean
Today's Astronomy Picture of the Day focuses on the region of the constellation Gemini, riding high in the northern hemisphere skies this time of the year. Sharpless 249 is on the left and cosmic sea inhabitant IC 443, the Jellyfish Nebula, is on the right. IC 443 is related in origin to Messier 1, The Crab Nebula in that not only do both have oceanic nicknames but both were born from supernova events.
