Into the constellation of Sagittarius - Milkyway From the 10th National Annual Star Party of Greek Amateur Astronomers at mountain Parnon. Special thanks to the Astronomical Union of Sparta! Sagittarius is one of the constellations of the zodiac. It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy and remains one of the 88 modern constellations. Its name is Latin for the archer, and its symbol is Sagittarius.svg (Unicode U+2650 ♐), a stylized arrow. Sagittarius is commonly represented as a centaur pulling-back a bow. It lies between Scorpius and Ophiuchus to the west and Capricornus to the east. The center of the Milky Way lies in the westernmost part of Sagittarius. As seen from the northern hemisphere, the constellation's brighter stars form an easily recognizable asterism known as 'the Teapot'. The stars δ Sgr (Kaus Media), ε Sgr (Kaus Australis), ζ Sgr (Ascella), and φ Sgr form the body of the pot; λ Sgr (Kaus Borealis) is the point of the lid; γ2 Sgr (Alnasl) is the tip of the spout; and σ Sgr (Nunki) and τ Sgr the handle. These same stars originally formed the bow and arrow of Sagittarius. Marking the bottom of the teapot's "handle" (or the shoulder area of the archer, are the bright star (2.59 magnitude) Zeta Sagittarii (ζ Sgr), named Ascella, and the fainter Tau Sagittarii (τ Sgr). To complete the teapot metaphor, under good conditions, a particularly dense area of the Milky Way can be seen rising in a north-westerly arc above the spout, like a puff of steam rising from a boiling kettle. The Milky Way is at its densest near Sagittarius, as this is where the galactic center lies. As a result, Sagittarius contains many star clusters and nebulae. Nebulae Sagittarius contains several well-known nebulae, including the Lagoon Nebula (Messier 8), near λ Sagittarii; the Omega Nebula (Messier 17), also known as the Horseshoe Nebula or Swan Nebula, near the border with Scutum; and the Trifid Nebula (Messier 20), a large nebula containing some very young, hot stars. The Lagoon Nebula (M8) is an emission nebula that is located 5,000 light-years from Earth and measures 140 light-years by 60 light-years (1.5°). Though it appears grey in telescopes to the unaided eye, long-exposure photographs reveal its pink hue, common to emission nebulae.[8] It is fairly bright, with an integrated magnitude of 3.0. The Lagoon Nebula was discovered independently by John Flamsteed in 1680, Guillaume Le Gentil in 1747, and Charles Messier in 1764. The central area of the Lagoon Nebula is also known as the Hourglass Nebula, so named for its distinctive shape. The Hourglass Nebula has its shape because of matter propelled by Herschel 36. The Lagoon Nebula also features three dark nebulae catalogued in Barnard's Catalog. The Lagoon Nebula was instrumental in the discovery of Bok globules, as Bart Bok studied prints of the nebula intensively in 1947. Approximately 17,000 Bok globules were discovered in the nebula nine years later as a part of the Palomar Sky Survey; studies later showed that Bok's hypothesis that the globules held protostars was correct. The Omega Nebula is a fairly bright nebula; it has an integrated magnitude of 6.0 and is 4890 light-years from Earth. It was discovered in 1746 by Philippe Loys de Chésaux; observers since him have differed greatly in how they view the nebula, hence its myriad of names. Most often viewed as a checkmark, it was seen as a swan by George F. Chambers in 1889, a loon by Roy Bishop, and as a curl of smoke by Camille Flammarion. The Trifid Nebula (M20, NGC 6514) is an emission nebula in Sagittarius that lies less than two degrees from the Lagoon Nebula. Discovered by French comet-hunter Charles Messier, it is located between 2,000 and 9,000 light-years from Earth and has a diameter of approximately 50 light-years. The outside of the Trifid Nebula is a bluish reflection nebula; the interior is pink with two dark bands that divide it into three areas, sometimes called "lobes". Hydrogen in the nebula is ionized, creating its characteristic color, by a central triple star, which formed in the intersection of the two dark bands. M20 is associated with a cluster that has a magnitude of 6.3. The Red Spider Nebula (NGC 6537) is a planetary nebula located at a distance of about 4000 light-years from Earth. NGC 6559 is a star forming region located at a distance of about 5000 light-years from Earth, in the constellation of Sagittarius, showing both emission (red) and reflection (bluish) regions. The grouping of the Lagoon Nebula, the Trifid Nebula, and NGC 6559 is often called the Sagittarius triplet. In addition, several other nebulae have been located within Sagittarius and are of interest to astronomers. M24, also called the Small Sagittarius Star Cloud, is a star cluster with an approximate magnitude of 3. About 9400 light-years away, it has a diameter of approximately 330 light-years. Embedded in M24 is NGC 6603, a smaller star cluster that is very dense. NGC 6567, a dim planetary nebula, and Barnard 92, a Bok globule, are also nearby. NGC 6445 is a planetary nebula with an approximate magnitude of 11. A large nebula at over one arcminute in diameter, it appears very close to the globular cluster NGC 6440. NGC 6638 is a dimmer globular at magnitude 9.2, though it is more distant than M71 at a distance of 26,000 light-years. It is a Shapley class VI cluster; the classification means that it has intermediate concentration at its core. It is approximately a degree away from the brighter globulars M22 and M28; NGC 6638 is southeast and southwest of the clusters respectively. text : bit.ly/2aQwWsc Canon eos 6D, EF 85 f1.2 LII, 85mm, f/2.8, iso800, 6X3min, Skywatcher EQ6, Unguide, DSS, PS

This is my second attempt in taking milky way pictures.
Flares are not Photoshopped some might ask :)
Everything is taken in one frame and image is not cropped at all.
All I did was a normal post-process using LR 4.3.
This month’s theme really pushed me outside of my comfort zone and I am glad for it.
Any comments on improving the shot would be appreciated and thank you for viewing.
In complete darkness of Kyrgyz Tien Shan mountains, without the presence of light pollution within several hundred kilometers around, I don't remember the last time I had a such a good view of the disk of our galaxy. As that wasn't already enough even a meteor flew into the frame
A collection of some of the finest SHIPs in the galaxy! Well, one did catch fire and explode, but before that it was pretty fine.
Happy SHIPtember!
Managing the water supply on an interstellar colony vessel is just about the best job on board, so the competition for available positions on the water staff is fierce. The primary perk for staff members is occasional access to the water chamber itself, which is vast and beautiful. Here we see lucky water system engineers heading for the far end of the chamber on a quarterly inspection. They will spend several hundred rotation cycles on this task, a time period roughly equivalent to 18 terrrestrial hours. On some inspections they are actually allowed to catch one fish per person... if they have enough skill or luck to land a wily interstellar perch at 1/3 earth-normal gravity. Good luck, fishernauts!
The Interstellar Spark is one piece of Blacktron II technology that is an example of the expression: “If its not broken… don’t fix it!”. With a heavy bulky structure, this ship won’t break a lot of record speeds like its successors, but it is one of the most reliable Vic Vipers in use by the Blacktron II air force.

This small Vic Viper was part of my participation on the New Elementary - 2019 Parts Fest #2.
You can see some of the other builds I made here:

And here is a small description of the process:
"When I saw the Roof Tile 1x8x3 Deg 25 No 1 in White (6262530|49618) I thought that they would be great to make spaceship wings because of their larger surface areas with fewer lines/unions. Since we are in “Novvember" I decided to make this year’s Vic Viper. Although I wanted to make a cleaner ship, I was able to incorporate some greebling on the wings using the “circular saw” part from the Mini Accessory, No. 11."
I was so glad that I was able to see this movie in theaters the day after it came out. It instantly became my favorite movie, and I decided that I wanted to make a Ranger. However, after seeing all the amazing Rangers that others have built, I kind of lost interest for awhile.
It wasn't until the digital release that I decided to try. It's taken me since March to complete this, and I nearly gave up multiple times, but I really wanted a Ranger model in my collection, so I kept with it. Here are the end results. It does have some interior detailing, which was actually easier to do than the exterior. Sadly, I don't have too many Computer panel pieces, so it doesn't have a lot of screens like it does in the movie. Also, one last bit. I tried to scale this based on how big the Endurance is (There is an infographic that shows how big the Endurance -With Rangers- is compared to the U.S. Space Shuttle.) I used that to try and get a rough size for my Ranger model, and while it looks a little large when compared to minifigures, I am quite happy with the results.

This 250 GTO, S/N 3757, was bought by Nick Mason, Pink Floyd drummer and composer, for approximately $86,000, in 1978.
It is now estimated at $31 million...

Interstellar
- (adjective) occurring or situated between stars.
I made jam for the first time this year. Since my Nana died, I have taken responsibility for preserving the abundance of fruit that still grows in her garden. This is pink gooseberry and rhubarb, although in this teaspoon I think it looks like the formation of a galaxy, a supernova or a distant nebula.
What is this world? I'm off to bathe in the ruby waters and once I'm satisfied, I'll swim to the nearby still, teal-colored pool to contemplate how I got here.
The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion).
The oblate shells of ESO 455-10, previously held tightly together as layers of its central star, not only give this planetary nebula its unique appearance, but also offer information about the nebula. Seen in a field of stars, the distinct asymmetrical arc of material over the north side of the nebula is a clear sign of interactions between ESO 455-10 and the interstellar medium.
The interstellar medium is the material such as diffuse gas between star systems and galaxies. The star at the center of ESO 455-10 allows Hubble to see the interaction with the gas and dust of the nebula, the surrounding interstellar medium, and the light from the star itself. Planetary nebulae are thought to be crucial in galactic enrichment as they distribute their elements, particularly the heavier metal elements produced inside a star, into the interstellar medium which will in time form the next generation of stars.

Bond And Free
Love has earth to which she clings
With hills and circling arms about--
Wall within wall to shut fear out.
But Thought has need of no such things,
For Thought has a pair of dauntless wings.
On snow and sand and turn, I see
Where Love has left a printed trace
With straining in the world's embrace.
And such is Love and glad to be
But Thought has shaken his ankles free.
Thought cleaves the interstellar gloom
And sits in Sirius' disc all night,
Till day makes him retrace his flight
With smell of burning on every plume,
Back past the sun to an earthly room.
His gains in heaven are what they are.
Yet some say Love by being thrall
And simply staying possesses all
In several beauty that Thought fares far
To find fused in another star.
