Cometary Globules CG 30, CG 31 and CG 38 in Puppis - From Rolf Wahl Olsen - https://flic.kr/p/mgEwye
Pictured against the sprawling star fields and dark clouds of the Southern constellation Puppis are some ghostly glowing structures known as cometary globules. They owe their existence to complex interactions between gas and dust and the intense ultraviolet radiation from young O type stars in their neighbourhood. And possibly also to supernova explosions in the distant past. Passing shock waves and radiation pressure have interacted with density fluctuations in the interstellar medium, and caused the formation of condensations called Bok globules. The radiation is also ionizing Hydrogen gas in the area, visible as the faint pink glow, while slowly eroding away the condensed globules and blowing their contents out into long tails, similar to that of a comet. Radio observations from ESO's La Silla observatory in Chile have shown that the gas in the globules has a temperature of some 5,000 to 14,000 Kelvin. Within the dense globules new stars are being born and at least one of these is visible as a bright orange glow in the dense upper right globule CG 30. This is a Herbig-Haro object (HH120); the result of plasma jets ejected from young protostars which collide with the surrounding gas and dust and cause the glowing emission. These delicate light-year wide structures are relatively short lived and will ultimately succumb to the emerging radiation pressure from the very stars born within them. Within a few hundred thousand years a splendid cluster of young bright stars ...

This is a new image from #JWST.

The bright points with spikes are stars in the Milky Way.

I know I post many Cornish sunsets that I have filmed, and I hope they don’t feel repetitive. I just feel they can help folks in a small way to feel a moment of calm if you’re struggling and to remind you that there is still a great deal that is beautiful in our world. Rest well, my friends. #calm

Released from Hubble a few days ago - the image shows a giant among galaxies LEDA 1313424 or, the Bullseye.

A smaller blue dwarf galaxy went through the centre leaving 9 star filled rings.

Like dropping a pebble into a pond!

Beautiful morning light illuminates the Canadian Rockies' towering Mount Assiniboine as, ever so briefly, underlying rocks and pebbles show through before the winds pick up again.

No matter how dull conditions, there are always photographic opportunities! A long exposure brings out streaking clouds, against the turquoise waters of beautiful Moraine lake in the Canadian Rockies.

Took this image 27 days ago on Christmas Eve (seems so long ago now!). The Cone Nebula and Christmas Tree Cluster (NGC 2264). 96 images at 5 minutes each (8 hours) in Sulphur II, Hydrogen Alpha and Oxygen III.

The Horsehead Nebula (also known as Barnard 33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion’s Belt, and is part of the much larger Orion Molecular Cloud Complex.

Hold on to your butt because we just got an awesome new JWST image!!!

In the bottom right you can see the dwarf galaxy Leo P, around 5.3 million light years from us! It’s a really interesting galaxy to study… 🧵🧪🔭

A model image of what our home galaxy, the Milky Way, might look like face-on: as viewed from above the disc of the galaxy, with its spiral arms and bulge in full view. In the centre of the galaxy, the bulge shines as a hazy oval, emitting a faint golden gleam. Starting at the central bulge, several glistening spiral arms coil outwards, creating a perfectly circle-shaped spiral. They give the impression of someone having sprinkled pastel purple glitter on the pitch-black background, in the shape of sparkling, curled-up snakes. A model image of what our home galaxy, the Milky Way, might look like edge-on, against a pitch-black backdrop. The Milky Way’s disc appears in the centre of the image, as a thin, dark-brown line spanning from left to right, with the hint of a wave in it. The line appears to be etched into a thin glowing layer of silver sand, that makes it look as if it was drawn with a coloured pencil on coarse paper. The bulge of the galaxy sits like a glowing, see-through pearl in the shape of a sphere in the centre of this brown line

This image shows the Antennae Galaxies (NGC 4038 & NGC 4039), 60 million light-years away in Corvus. These galaxies are in the process of merging, creating tidal tails and bursts of star formation from their gravitational interaction.

Look at this marvel!

The composite image, featuring the galaxy group Stephan's Quintet, combines Webb's infrared data with X-rays data by Chandra.
Stefan's Quintet, along with other cosmic objects, is part of the first Webb's observations.

This composite image features the galaxy group Stephan's Quintet, combining Webb's infrared data with X-rays data by Chandra and including infrared data from the Spitzer telescope (red, green, blue). The JWST data (red, orange, yellow, green, blue) shows incredible details of the galaxy interactions, including sweeping tails of gas and bursts of star formation. Stephan's Quintet is a visual grouping of five galaxies located about 290 Mly away in the constellation Pegasus; clockwise from upper left: NGC 7320, NGC 7319, NGC 7318 (a and b), NGC 7317.
