also known as RAFGL 2688 and CRL 2688, the Egg Nebula is located 3000 light years from Earth in the constellation of Cygnus.
The nebula is a bi-polar proto-planetary nebula, or essentially a star in the dying days of it's existence starting to throw out shells of atmosphere as it moves towards being a white dwarf.
The central star is concealed by an area of dust with the light poking out in areas where the dust is lightest, this is thought to be an accretion disk around the star.
Stars and Dust Across Corona Australis : Cosmic dust clouds cross a rich field of stars in this telescopic vista near the northern boundary of Corona Australis, the Southern Crown. Less than 500 light-years away the dust clouds effectively block light from more distant background stars in the Milky Way. Top to bottom the frame spans about 2 degrees or over 15 light-years at the clouds’ estimated distance. At top right is a group of lovely reflection nebulae cataloged as NGC 6726, 6727, 6729, and IC 4812. A characteristic blue color is produced as light from hot stars is reflected by the cosmic dust. The dust also obscures from view stars in the region still in the process of formation. Just above the bluish reflection nebulae a smaller NGC 6729 surrounds young variable star R Coronae Australis. To its right are telltale reddish arcs and loops identified as Herbig Haro objects associated with energetic newborn stars. Magnificent globular star cluster NGC 6723 is at bottom left in the frame. Though NGC 6723 appears to be part of the group, its ancient stars actually lie nearly 30,000 light-years away, far beyond the young stars of the Corona Australis dust clouds. via NASA
i learned that the Sun is 99.86% of all mass in our solar system. Every other planet, asteroid, and comet only adds up to 7/50th of a single percent (x)
IC 342: Hidden Galaxy
"IC 342 is a challenging cosmic target. Although it is bright, the galaxy sits near the equator of the Milky Way’s galactic disk, where the sky is thick with glowing cosmic gas, bright stars, and dark, obscuring dust. In order for astronomers to see the intricate spiral structure of IC 342, they must gaze through a large amount of material contained within our own galaxy — no easy feat! As a result IC 342 is relatively difficult to spot and image, giving rise to its intriguing nickname: the “Hidden Galaxy.” Located very close (in astronomical terms) to the Milky Way, this sweeping spiral galaxy would be among the brightest in the sky were it not for its dust-obscured location. The galaxy is very active, as indicated by the range of colors visible in this NASA/ESA Hubble Space Telescope image, depicting the very central region of the galaxy. A beautiful mixture of hot, blue star-forming regions, redder, cooler regions of gas, and dark lanes of opaque dust can be seen, all swirling together around a bright core. In 2003, astronomers confirmed this core to be a specific type of central region known as an HII nucleus — a name that indicates the presence of ionized hydrogen — that is likely to be creating many hot new stars."

As promised, it’s finally here! Thank you to all of my patrons for not only the support that made this possible, but for giving me the confidence to work on a big project like this.
Rather than providing any drawing instruction, what this writeup aims to do is help you learn to unpack the decisions being made in a given composition, and articulate what elements in a piece are responsible for its impact. Being able to isolate these qualities in your own art and art that inspires you opens up avenues for improvement regardless of medium, style, or technical skill. This is the first of hopefully many PWYW art ‘tutorials’ from me.
I hope you all enjoy!
I just reblog fun facts/tipsScience, nature, geology facts etc! + art & writing tips!
