A starfield is shown with a large brown dust nebula in the center. The nebula appears, to some, to be shaped like a bat. One of the stars in the dust nebula even appears to be the eye of the bat. Please see the explanation for more detailed information.

2021年10月27日 NGC 6995: The Bat Nebula Image Credit & Copyright: Howard Trottier Explanation: Do you see the bat? It haunts this cosmic close-up of the eastern Veil Nebula. The Veil Nebula itself is a large supernova remnant, the expanding debris cloud from the death explosion of a massive star. While the Veil is roughly circular in shape and covers nearly 3 degrees on the sky toward the constellation of the Swan (Cygnus), NGC 6995, known informally as the Bat Nebula, spans only 1/2 degree, about the apparent size of the Moon. That translates to 12 light-years at the Veil’s estimated distance, a reassuring 1,400 light-years from planet Earth. In the composite of image data recorded through narrow band filters, emission from hydrogen atoms in the…
