Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light; a little too much pseudoscience and not enough science.

Good morning. It is November 2, and today's photo showcases the Veil Nebula, a cloud of heated and ionized gas about 2,400 light-years away from Earth.
