Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nulcei powered by supermassive central black holes!
Heralded as the most famous celestial band -- second only to the rings of Saturn -- the Ring Nebula (also categorized as M57) glows with impressive "looping structures," in a way that looks stunningly like a giant blooming flower floating in space. Luckily for us, the Hubble Space Telescope captured an image in beautiful detail, considering the Ring Nebula exists 2,000 light years away from Earth.
Tulip Nebula, at least in the field seen from earth, is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. It is also called Sharpless 101 (Sh2-101) or the Cygnus Star Cloud because the nebula located in the constellation Cygnus.
Celestial Emissions - Eta Carina Nebula by strongmanmike2002. Glowing regions of gas in our galaxy are known as emission nebulae. Imaging these nebulae through filters that only allow the passage of very specific wavelengths of light produces this type of image.
