Rick's #Astrophotography Picture of the Day (from my growing collection of captures) - Wide‑Field Mosaic of NGC 7822 & SH2‑171 - 9/8/24

This region in Cepheus is a huge complex of emission nebulae and stellar nurseries and contains some of the hottest stars in our spiral arm.

My god. It's full of stars.

This sparkling #JWST stellar scene is Westerlund 2, a young star cluster only a few million years old and containing some of the hottest, most massive stars known.

Westerlund 2 is situated within the Gum 29 stellar nursery, and is around 20,000 lightyears from home.
A sparling scene is six-pointed stars, with a large cluster at upper centre and a particularly bright example at lower right. The background is wispy and in shades of blue and grey–red, with a bright border of reddy–orange clouds along the left and bottom of the scene.

❄️ With the winter holidays around the corner, we’re unwrapping a cosmic gift early, Westerlund 2 🎁✨

This glittering star cluster is host to some of our Milky Way galaxy's hottest, brightest, and most massive stars 👉 www.esa.int/ESA_Multimed...

🔭 🧪
A cluster of stars inside a large nebula. The clouds of gas and dust are predominantly bright red in colour and wispy, akin to flames. They are clumped in the bottom-left corner. Other clouds, deeper in the cluster behind many of the stars, appear pale pink. The stars are concentrated in the top half of the image and are mostly small, bright white and six-pointed. They cast blue light over the nebula. Other stars with very long spikes surrounding them lie in the foreground.

NGC 2264 is known as the Cone Nebula & the Christmas Tree Cluster & lives about 1000 ly from Earth in the constellation Monoceros. This 11 hr OSC capture was taken last February using a 102mm refractor with no filters. Finally got around to processing it in time for the holidays. 🔭 #Astrophotography
A star field with a magenta and red nebula in the shape of a Christmas tree fills the frame. At the top is a bright patch at the small end of a cone shaped nebula. The cone is upside down from the rest of the Christmas tree like an ornament at the top of it.

TODAY’S NEW HUBBLE IMAGE OF THE LOST GALAXY 🌌
A close-in view of a spiral galaxy that faces the viewer. Brightly lit spiral arms swing outward through the galaxy’s disk, starting from an elliptical region in its center. Thick strands of dark reddish dust spread across the disk, primarily along the spiral arms. The arms also contain many glowing, pink-red spots where stars form and clumps of bright-blue star clusters. Beyond its spiral arms, the galaxy is a bit fainter and speckled with blue stars.

I FOUND THE FULL RESOLUTION OF THE NEW JWST IMAGE AND I’M SPEECHLESS!!!
In what appears as a celestial dreamscape, a blue and black sky filled with brilliant stars covers about two thirds of the image. The stars are different sizes and shades of white, beige, yellow, and light orange. Across the bottom third of the scene is a craggy, mountain-like vista with spire-like peaks and deep, seemingly misty valleys. These so-called mountains appear in varying shades of orange, yellow, and brown. The soaring spires are going up, up, up, where a wispy, ethereal white cloud stretches horizontally across the scene. Steam appears to rise from the mountaintops and join with this cloud. At the top, right corner of the image, a swath of orange and brown structure cuts diagonally across the sky.

We’re here to sweep you away … with an intricate Hubble view of a star-forming region near the Tarantula Nebula. Stars form when clumps of gas become dense enough. The clumps are typically shrouded in dust, which appears dark brown here.

Credit: NASA, ESA. 🔭 🧪
Hubble Space Telescope image is awash in color and hundreds of stars. Dozens of bright blue stars are scattered across the field, some appearing larger than others, and most with four diffraction spikes. Many stars throughout appear bright red, also with diffraction spikes. The red stars are all smaller than the blue stars, and many are so tiny they appear only as pinpricks. Semi-transparent gas and dust are spread throughout, like gauzy layers of fabric. Light gray layers of gas and dust start at top left and drift down toward the bottom right, forming a rough upside-down V shape. From top middle to right middle, darker and thinner filaments of brown dust flow irregularly, with some portions denser and darker, like knots. The top right corner has lighter blue semi-transparent material. Toward the bottom left and up toward the center, there’s a slightly clearer area that has deeper blue semi-transparent material.

the human eye can’t even SEE the full image that rubin took of this portion of the sky.

it would take 400 ULTRA HD tv screens for our eyes to be able to see it.

the field of view is 45 TIMES the area of the full moon.

we are entering a new era of astronomy.
A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry. Throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black.

this is where i live btw
At the center is a thin vertical cloud known as Lynds 483 that is shaped like an hourglass with irregular edges. At lower center are two discrete bright white, tiny blobs of light that have raced away from the hidden central stars. The top lobe shows a more prominent orange U-shape. Orange bleeds into light purple, and brighter pink at its edges. Some background stars are visible through sections of this lobe. Higher up, there is an orange arc. Some brighter pink material extends to the top edges near the center. In the lower lobe, less orange is visible. More opaque light purple is in its top third, rippling out into semi-transparent blues and pinks. The lower lobe has more texture. V-shapes left and right of the lobes are darkest, and the background stars in these areas appear orange. Elsewhere, the black background of space is clearer, speckled with tiny white stars and faint orange galaxies. A star cluster is shown inside a large nebula of many-coloured gas and dust. The material forms dark ridges and peaks of gas and dust surrounding the cluster, lit on the inner side, while layers of diffuse, translucent clouds blanket over them. Around and within the gas, a huge number of distant galaxies can be seen, some quite large, as well as a few stars nearer to us which are very large and bright. A wider field view of Westerlund 1. A dense cluster of bright stars, each with six large and two small diffraction spikes, due to the telescope’s optics. They have a variety of sizes depending on their brightness and distance from us in the cluster, and different colours reflecting different types of star. Patches of billowing red gas can be seen in and around the cluster, lit up by the stars. Small stars in the cluster blend into a background of distant stars and galaxies on black. Red dual opposing jets coming from young stars fill the darker top half of the image. At bottom center is a glowing pale yellow, cave-like structure, its top tilted toward two o’clock, with a bright star at its center. The dust of the cave structure becomes wispy toward eight o’clock. Above the arched top of the dust cave, 3 groupings of stars with diffraction spikes are arranged. A dark cloud sits at the top of the arch of the glowing dust cave, with one streamer curling down the right-hand side. The dark shadow of the cloud appears pinched in the center, with light emerging in a triangle shape above and below the pinch, revealing the presence of a star inside the cloud. The largest jets of red material emanate from within this dark cloud, thick and displaying structure like the rough face of a cliff, glowing brighter at the edges. At top center, a star displays another, larger pinched dark shadow, this time vertically. To the left of this star is a more wispy, indistinct region.

take me here so i can escape earth for a little while
Very dark gray material shaped like a triangle or shark fin extends from just below top left all the way down to the lower right corner and back up toward the top right. It looks like thick smoke that has billowed out irregularly, thicker along the line from top left to bottom right, and looser on the piece that goes toward the top right. Behind the dark gray on the left side, from the bottom left to top center, there is dust that looks like arced claw marks that appears in light orange and yellow. The background at top left is hazier and some blues are covered in semi-transparent orange wisps, which makes sections take on green hues. In the bottom right, the background is bluer. There are a few bright red and purple stars scattered along the right half, most toward the bottom. The largest star is at right-center, just at the edge. It is red and has four diffraction spikes. A tall, thin structure of dark gas clouds. This pillar is darker and broader at its base, thins toward the middle, and broadens out again at the top, with spikes, fingers, and wisps of gas protruding in all directions from its head. Some parts of the pillar are illuminated, but most are dark and silhouetted at the edges and lit from behind. A wall of colorful gas lies behind the pillar, bluish at the top and redder toward the bottom, with several blue and gold stars scattered across it. A massive spiral galaxy fills the image, with its bright yellow core seen near the upper left. Spiral arms whirl outward, laced through with dark brown dust and bright blue patches of star formation. A densely packed cluster of yellow stars shines at the center of the image, with more stars scattered throughout. Clouds of glowing indigo gas and dust dominate the lower half of the view, and a red star with diffraction spikes shines at upper right.

the helix nebula has always been one of my favorites cause it looks like a giant space eyeball
In this composite image, a cloud of gas strongly resembles a large eye. Here, a hazy blue cloud is surrounded by misty, concentric rings of pale yellow, rose pink, and blood orange. Each ring appears dusted with flecks of gold, particularly the outer edges of the eye shape. The entire image is speckled with glowing dots in blues, whites, yellows, and purples.

A spiral galaxy seen at a skewed angle. Its center is a bright spot radiating light. A thick, stormy disk of material surrounds this bright center, with swirling strands of dark dust and bright spots of star formation strewn through the disk. A large spiral arm extends from the disk toward the viewer. Some foreground stars are visible atop the galaxy. A spiral galaxy, seen tilted at a slight angle, on a dark background of space. It glows softly from its center and out to its edge. The disk is a broad swirl of dark-reddish dust webs and sparkling blue patches where stars have formed. Atop the center of the galaxy is a foreground star that appears very large and bright with four diffraction spikes emanating from it. The star is relatively close to Earth compared to the galaxy. A large galaxy is at center, and a significantly smaller galaxy is to its left. The large galaxy is mostly face-on, but the top appears slightly tilted away. It has several rings. Its circular core is bright white at the very center, but light yellow overall. Going outward, there are gaps between the rings. The core is surrounded by two slightly lighter yellow rings, which also appear to be overlapping. The next ring is slightly more transparent and yellow. The two or three rings that are farther out are bluer, sometimes with blue clumps. The widest ring is also blue, but also the most transparent. At 9 o’clock is a small dwarf galaxy. It is about the same size as the yellow core of the Bullseye. The dwarf galaxy is blue, with many dots. It looks like the edge of the Bullseye might touch the dwarf galaxy. Both galaxies are set on the black background of space, which is dotted with a range of galaxies in different shapes, colors, and sizes, along with one foreground star at left. A massive spiral galaxy fills the image, with its bright yellow core seen near the upper left. Spiral arms whirl outward, laced through with dark brown dust and bright blue patches of star formation.

A thick, stormy disk of material surrounds this bright center, with swirling strands of dark dust and bright spots of star formation strewn through the disk. A large spiral arm extends from the disk toward the viewer. Some foreground stars are visible atop the galaxy. Dark brown pillars rise from the bottom to the top of the image, ending in three points. The background is opaque, set off in yellow and green toward the bottom and blue and purple at the top. A handful of stars of various sizes appear. An area of deep space with thousands of galaxies in various shapes and sizes on a black background. A few gold-colored galaxies are bunched closely together in the center. A large, translucent purple cloud lies over the galaxies, thickest across the center where the gold galaxies sit, and fainter up to the right. This shows where X-rays are emitted by hot gas in the group of galaxies. A star cluster is shown inside a large nebula of many-coloured gas and dust. The material forms dark ridges and peaks of gas and dust surrounding the cluster, lit on the inner side, while layers of diffuse, translucent clouds blanket over them. Around and within the gas, a huge number of distant galaxies can be seen, some quite large, as well as a few stars nearer to us which are very large and bright.

i need some space… and maybe you do too
A massive spiral galaxy fills the image, with its bright yellow core seen near the upper left. Spiral arms whirl outward, laced through with dark brown dust and bright blue patches of star formation. Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout. A densely packed cluster of yellow stars shines at the center of the image, with more stars scattered throughout. Clouds of glowing indigo gas and dust dominate the lower half of the view, and a red star with diffraction spikes shines at upper right. A nebula made up of cloudy gas and dust in the form of soft and wispy clouds and, in the center, thin and highly detailed layers pressed close together. Large, bright stars surrounded by six long points of light are dotted over the image, as well as some small, point-like stars embedded in the clouds. The clouds are lit up in blue close to the stars; orange colors show clouds that glow in infrared light.

A collage of three near-infrared images showing a dusty nebula. The left two-thirds of the collage is taken up by a Hubble image of the nebula. The remaining third is taken up by two Webb images, one atop the other. The Hubble image has a pillar of dense brown dust running through the nebula at a diagonal from 5 o’clock to 11 o’clock. Wispy plumes appear to fly off from the pillar toward the sides amid blue clouds of the same material, which are whiter near the pillar. There are many white stars spread throughout. Two separate, white squares, tilted about 30 degrees, outline two areas in the pillar. The upper square has the letter “A” to the top right, while the lower square is marked by the letter “B”. These labels correspond to the two, magnified images of the nebula at right, with the top image also labeled “A” and the bottom image labeled “B”. Both images contain a mixture of reds, blues and browns, and show red, blue, and white stars.

A collage of four images showing a dusty nebula. Two-thirds of the collage is taken up by a single image of the nebula, while the remaining third shows three insets stacked on top of each other. In the largest image at left, there is an orange and yellow fang-like cloud of matter that cuts the image in two. The left side of the fang shows more clouds of a dark brown shade, while the right shows filaments of light brown. There are a number of bright blue and red points of light spread throughout, three of which are circled in white and labeled with a number from one to three. Circle 1 is located at about 12 o’clock in the middle of the fang-like cloud, while Circle 2 is at about 5 o’clock and Circle 3 is located at about 7 o’clock, toward the bottom left of the image. Each circle magnifies an individual object, which is shown in each of the three squares to the right of the collage, labeled 1 to 3 from top to bottom. Each image contains a single, fuzzy point of light in the middle.
