Happy launch anniversary JWST!

The telescope launched on December 25, 2021 on an Ariane 5 rocket from the European Spaceport near Kourou, French Guiana.

Thanks to the hard work of the people at ESA, JWST had a fantastic start to its trip out to its parking spot 1.5 million km away at L2.

The nebula with right in the middle the famous Pillars of Creation :)
eso.org ESO @eso.org · 1d
The Eagle Nebula is a dazzling stellar nursery. In it, a cluster of massive, hot stars, NGC 6611, has just been born.

The powerful light and strong winds from these massive new arrivals are shaping light-year long pillars.

A view of a Nebula, filled with glowing pink and red clouds of gas illuminated by bright, young stars. Dark, finger-like pillars of dust stretch upward from the nebula’s center. Countless stars of varying brightness sparkle across the scene.

🌟 Merry Christmas from a newborn star. Earlier this year the NASA/ESA/CSA #Webb Space Telescope took this stunning image of HH30, an edge-on protoplanetary disc. 🧪🔭

🔗 esa.int/Science_Exploration/Space_Science/Webb/Webb_investigates_a_dusty_and_dynamic_disc
A close-in image of a protoplanetary disc around a newly formed star. Many different wavelengths of light are combined and represented by separate and various colours. A dark line across the centre is the disc, made of opaque dust: the star is hidden in here and creates a strong glow in the centre. A band going straight up is a jet, while other outflows form flares above and below the disc, and a tail coming off to one side.

For the final day, 24, of #ArtAdventCalendar, I present this illustration which I call Exploration of Amalthea. The latter is a very small moon of Jupiter in a very close orbit. Jupiter would fill half the sky seen from here!

#SciArt #spaceart #Blender3d
Amalthea is a moon of Jupiter, the third closest to the planet at 181,365 km away (about 2.6 Jupiter radii from the centre of the planet). At just 250 km across at its widest point - its shape is not spherical - Amalthea is small, likely a captured asteroid. This image portrays a potential exploration party on the surface of Amalthea. From there, the globe of Jupiter spans an incredible 46 degrees of arc across the sky. The dark oval seen on the backdrop of Jupiter is the shadow cast by its moon Io.

This isn’t a scene of holiday lights gone awry—it’s cold dust in two galaxies! #NASAWebb’s mid-infrared observations uniquely capture the dust in exquisite detail. See how the pair looks when visible and UV light are added from Hubble: https://bit.ly/4oxgK0u
Two spiral galaxies take the shape of a colorful beaded mask that sits above the nose and is angled from top left to bottom right. The galaxy at left, IC 2163, is smaller, taking up a little over a quarter of the view. The galaxy at right, NGC 2207, takes up half the view. IC 2163 has a bright white core, with two prominent white spiral arms that rotate counterclockwise and become straighter toward the ends. Its arms are dotted with pink. NGC 2207 has a very bright core that is larger. Overall, it appears to have thicker spiral arms that spin counterclockwise. This galaxy also contains more pink areas of star formation. In the middle, the galaxies’ arms appear to overlap. The black background of space shows extremely distant galaxies that are tiny, and often red and orange smudges, as well as a few blue foreground stars.

Admire this captivating image of the spectacular spiral galaxy NGC 300, located approximately 6 Mly away in Sculptor.

What is striking about the image is the extraordinary abundance of stars that can be seen.

This captivating image features the spectacular spiral galaxy NGC 300, also known as Caldwell 70 or the Sculptor Pinwheel Galaxy. What is striking about the image is the extraordinary abundance of stars that can be seen. NGC 300 contains, in fact, many young hot blue stars, massive and very bright, dominating the outer spiral arms; they stand out very well in the image, contributing to the visibility of the galaxy.

Westerlund 2 looks just like a holiday scene in this new, magical image from the JWST.

Those red and orange gas clouds and thousands of bright stars recall the #Christmas vibe.

Image Description (from the source linked in the thread): "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."

This cosmic butterfly is IRAS 23077+6707, the largest planet-forming disc seen around a young star yet! 

Hubble has revealed it to be an unusually chaotic specimen, with wisps of material flying far beyond the disc 👉 https://esahubble.org/images/opo2606/

🔭
Near the center is an object that resembles an edge-on view of a hamburger. There is a diagonal dark strip (the meat patty) of dust, running from 1 o’clock to 7 o’clock, that obscures a central star. Curving away from either side of the dark strip are glowing white clouds (the buns) where dust is reflecting starlight. Credit: NASA, ESA, STScI, K. Monsch (CfA). Image processing: J. DePasquale (STScI).

The large barred spiral galaxy appears close to a smaller galaxy to the left, but they’re actually about 45 million light-years apart 👉 https://www.esa.int/ESA_Multimedia/Images/2025/12/Euclid_s_galaxy_garland

An image of space made by the Euclid telescope shows a bright barred spiral galaxywith two sweeping arms glowing in shades of blue and white against a deep black background dotted with stars. Its core is luminous. Its spiral arms curve gracefully outward to the left and down to the right, resembling a cosmic garland draped across the scene. A smaller, faint and round galaxy appears to the left of the barred spiral galaxy.

💥 A “planet” near the star Fomalhaut just vanished — because it was never a planet. New Hubble observations show it’s debris from massive asteroid collisions. Astronomers now think these crashes are far more common than expected.
