NASA has shared a photo of NGC 2899, a nebula in space that looks like a butterfly. It sits about 4,500 light years away in the constellation Vela. According to the European Space Agency, its shape comes from radiation and stellar winds pushed out by a white dwarf at its center, which is nearly 22,000 degrees Celsius. The colors come from glowing hydrogen and oxygen. What do you see when you look at it? (Image: NASA, ESA, STScI) #Pubity
