Astro Advent starts here tomorrow, and a new picture follows every day from then until Christmas.
PS This is assuming no technical problems or other December disasters.

.1 If we were close enough to globular cluster Palomar 6, we'd see an amazing skyful of stars. Gravity pulls its half a million stars into a globe shape. This image captured by the Hubble Space Telescope shows an area of about 15 light years across. It's quite a starry night. [Credit: ESA/Hubble & NASA, R. Cohen][APOD]There are some 200 globular clusters in the Milky Way, most of them a long way from the center of the Galaxy. Although Palomar 6 is closer to the central area, it's still thought to be older than the Milky Way itself.Palomar 6 globular star cluster – click to enlarge

.2 The Carina Nebula is a massive star formation region. It's around 460 light years across and lies some 8,500 light years from us. This image was taken in infrared light using a camera on the VLT (Very Large Telescope) of the European Southern Observatory (ESO). [Credit: ESO/T. Preibisch]ESO's work is supported by a number of European countries and its Chilean host. There are telescopes in three observing sites in the high altitude Atacama Desert with its superb viewing conditions.Carina Nebula.

.3 The Andromeda Galaxy is a large spiral galaxy, a member of our Local Group. It's also speeding towards us on a collision course, but that's a few billion years off. An astrophotograph Andromeda Galaxy, The Neighbour earned Yang Hanwen and Zhou Zezhen of Sichuan, China the award of Young Astronomy Photographer of the Year 2022. One of the judges commented that the photograph was “very natural-looking rendering of the Andromeda Galaxy,” commending it as “the best example of precise postprocessing” which produced “a superb capture” by young astrophotographers who “demonstrated exceptional talent in processing a deep-sky photo." Andromeda Galaxy.

.4CW Leonis is a carbon star located about 400 light years away in the constellation Leo. It looks as though it's surrounded by cobwebs, but they are the outer layers this dying star is throwing off. It's on its way to becoming a white dwarf. [Credit: ESA/Hubble, NASA, and Toshiya Ueta (University Of Denver), Hyosun Kim (KASI)][Astronomy Now]The star has the low surface temperature of 1260°C, giving it a red-orange color. (Our Sun is 5800°C.)CW Leonis, carbon star.

.5Photographer Giulio Cobianchi captured an exquisite skyscape from a mountain with a view of the beautiful Lofoten Islands in northern Norway. His photograph Inception was one of those Capture the Atlas chose to feature in their 2022 Northern Lights Photographer of the Year.Cobianchi describes his composition: Under the Milky Way, you can see the Andromeda Galaxy in the middle of the two arcs. A shooting star acts as the cherry on top, and above a colorful Aurora, there is one of the most beautiful constellations, the Big Dipper! To the north, you can still see the light of the sun, which had recently gone below the horizon. Inception.

.6NASA's Juno spacecraft imaged Jupiter and its moon Ganymede. Jupiter and the shadow of its biggest moon, Ganymede, dominate this view. [Credit: NASA/JPL-Caltech/SwRI/MSSS Image processing by Thomas Thomopoulos © CC BY]Elizabeth Howell writes: NASA's Juno mission whizzed close by the radiation-spewing planet for the 40th time on Feb. 25 [2022], with the resulting raw images of the encounter beamed home to Earth. There, citizen scientist Thomas Thomopoulos created this stunning view based on what was seen by the JunoCam instrument. Jupiter and Ganymede.

.7NASA’s Solar Dynamics Observatory caught the Sun with a happy smiling face. This is an amusing example of pareidolia, where we see what seems to be a meaningful image in a random visual pattern. [Credit: NASA, Sciencealert.com]NASA Sun/Twitter explained: Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space. A smiling Sun.

.8One of the best known images from the Hubble Space Telescope is known as The Pillars of Creation. The James Webb Space Telescope [JWST] has produced a fantastic new image of this feature. [Image credit: NASA, ESA, CSA, STScI. Image Processing: Joseph DePasquale (STScI), Alyssa Pagan (STScI), Anton M. Koekemoer (STScI)]The “Pillars” are one of several star-forming regions in the Eagle Nebula. This nebula is a star cluster in the constellation Serpens about 7000 light years from us. JWST took two separate images of this area, using two different cameras. Combining them has produced a breathtaking new image. Pillars of Creation.
