A star forming region cataloged as NGC 2264, this beautiful but complex arrangement of interstellar gas and dust is about 2,700 light-years distant in the faint but fanciful constellation Monoceros, the Unicorn.

Our galaxy, the Milky Way, is moving towards the Andromeda galaxy. Astronomers predict that in about 4 billion years, the two galaxies will collide and begin to merge. The Solar System's fate is uncertain. It might end up in the final, larger galaxy, orbiting further from the core than it does now, or it might be ejected into space altogether.

Milky Way and Andromeda enjoy a dance of death. They're moving towards each other and will begin to merge in a few billion years.

Crikey!

A greyscale image of a spiral galaxy and its smaller companion. The frame is dominated by the large spiral. It has a small core that sits in the middle of a spiral structure. The one spiral arm begins at about 9 o'clock and curves clockwise around the galaxy, completing a full circle. The arm is unusually thick, fanning out with many bright star clusters. To the left of the spiral is a smaller galaxy, seen almost edge-on. It appears as an elongated oval dotted with stars. The long axis of the oval is almost horizontal. Connecting the two galaxies is a faint bridge of gas and stars. A few smaller background galaxies dot the black background of space. The image has some detector noise which have not been removed.

Hubble image of Arp 24, also known as NGC 3445.

NGC 3445 has one fan-like spiral arm that is dotted with star-forming regions. It is connected to its companion galaxy, seen nearly edge-on to the left, by a weak bridge.

A grainy, black and white image of two interacting galaxies. A large spiral galaxy with dark dust lanes is in the center of the image. It is tilted slightly, so that its disk forms an oval rather than a circle. The faint ends of spiral arms extend beyond the edge of the disk and appear to connect to its companion galaxy above it. The bright elliptical galaxy is oval shaped with a bright center that gets gradually fainter and more transparent towards its edges. A few white dots, which are stars, are seen on the black background of space.

NASA-JAXA XRISM Finds Elemental Bounty in Supernova Remnant science.nasa.gov/missions/xri...
For the first time, scientists have made a clear X-ray detection of chlorine and potassium in the wreckage of a star using data from the Japan-led XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft.

The Bipolar Jets of KX Andromedae apod.nasa.gov/apod/ap25120...
Blasting outward from variable star KX Andromedae, these stunning bipolar jets are 19 light-years long.

In the bottom right corner is a spiral galaxy with a bright pink-white central core encircled by two wispy arms that form a loose spiral around the core. The view is somewhat oblique, giving the galaxy an oval appearance. A long, thin, diffuse stream of blue stars and gas extends from the upper left side of the galaxy up to the upper left corner of the frame. Scattered across the background are hundreds of tiny smudges of light, which are stars and background galaxies. They vary slightly in size, shape, and color. Most appear in the shape of small dots, ovals, or lines. They come in different shades of red, blue and green.

With its helical appearance resembling a snail’s shell, this reflection nebula seems to spiral out from a luminous central star in this NASA/ESA Hubble Space Telescope image. The star in the center, known as V1331 Cyg and located in the dark cloud LDN 981 — or, more commonly, Lynds 981 — had previously been defined as a T Tauri star. A T Tauri is a young star — or Young Stellar Object — that is starting to contract to become a main sequence star similar to the sun. What makes V1331Cyg special is the fact that we look almost exactly at one of its poles. Usually, the view of a young star is obscured by the dust from the circumstellar disc and the envelope that surround it. However, with V1331Cyg we are actually looking in the exact direction of a jet driven by the star that is clearing the dust and giving us this magnificent view. This view provides an almost undisturbed view of the star and its immediate surroundings allowing astronomers to study it in greater detail and look for features that might suggest the formation of a very low-mass object in the outer circumstellar disk.

Centaurus A. A glowing orange region shines at the upper left corner, with dark brown and black dust cascading diagonally down to the lower right. Distant stars dot the hazy background of space. Bright pink regions of star formation are interspersed throughout the dust.

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 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.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which, have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.

A spiral galaxy in space. It is seen tilted at an angle, as a stormy disc filled with clouds of stars and dust. It is coloured more yellowish in the centre, and bluer out to the edge of the disc, where the ends of curved spiral arms break away from the disc. Spots of red light scattered through the galaxy mark where stars are actively forming. The galaxy is on a black background.

🔭 This weeks NASA/ESA Hubble Space Telescope image of the week features the stately and inclined spiral galaxy NGC 3511.

From Hubble’s vantage point in orbit around Earth, NGC 3511 is tilted by about 70 degrees!

Part of a nebula in space. Layers of gas and dust clouds in different colors, from blue and green shades to pink, red, and black, each indicating light emitted by different molecules, comprise the nebula. The background cloud layers are thicker and puffier, though still translucent, and the upper layers are thin and bright at the edges. Behind the clouds are many small, mostly orange and some blue, stars.

The Sombrero Galaxy is an oblong, pale white disc with a glowing core. It appears nearly edge-on but is slanted slightly in the front, presenting a slightly top-down view of the inner region of the galaxy and its bright core. The outer disc is darker with shades of brown and black. Different coloured distant galaxies and various stars are speckled among the black background of space surrounding the galaxy.

The NASA/ESA Hubble Space Telescope has returned to an old time favourite for its #Hubble35 anniversary!

The enigmatic Sombrero Galaxy has features of both spiral and elliptical galaxies. Read more 👉 www.esa.int/ESA_Multimed...
