Starry Greetings!

“ ...The lingering airglow is due to chemiluminescence, the production of light through chemical excitation. Originating at an altitude similar to aurora, it can found around the globe. The chemical energy is initially provided by the Sun's extreme ultraviolet radiation.” X

“The shockwave from a 20,000 year-old supernova explosion in the constellation of Cygnus is still expanding into interstellar space. The collision of this fast moving wall of gas with a stationary cloud has heated it causing it to glow in visible as well as high energy radiation, producing the nebula known as the Cygnus Loop (NGC 6960/95). The nebula is located a mere 1,400 light-years away. The colors used here indicate emission from different kinds of atoms excited by the shock: oxygen-blue, sulfur-red, and hydrogen-green. This picture was taken with the Wide Field and Planetary Camera 2 on board the Hubble Space Telescope.”

NASA has released new images of Jupiter, taken by the Juno Spacecraft.

NGC 1999

Just south of the Orion nebula is a dense area of dust and gas forming stars, in fact, the first Herbig-Haro stars were located here, protostars pushing intense beams of matter out at the poles.

The mystery is the black blob in the white region, a reflective nebula from the star V380 Ori, but what is the dark patch ?

Originally it was thought to be a dense dark cloud of dust, hiding the light, however further analysis has found it is indeed a hole, made to look black in contrast to the bright reflective surroundings.

Y’all are so excited about the new planetary discovery but I haven’t seen y’all share the Google doodle!

It’s so fucking adorable!
