This is the Carina Nebula, an interstellar cloud of dust, hydrogen, helium and other ionized gases. It lies within our own Milky Way galaxy, about 6,500-10,000 light-years from Earth. Like many nebulae, it is a star-forming region, and contains two of the most massive and luminous stars in our galaxy, along with multiple O-type stars. Our galaxy itself is estimated to contain 200-400 billion stars, and roughly ten times as many planets.
Cygnus Loop (also known as the Veil Nebula) - formed after a shockwave propagated through the material ejected during the supernova - subsequently heating up the surrounding material - causing it to glow. The nebula, which covers an expanse of space that is 6 times larger than the full moon, is ~ 2,500 light-years from Earth in Cygnus. Astronomers believe the supernova ignited 5-10,000 years ago; the light from the event first arrived on Earth at the end of the last ice age.
