A rare example of three active galactic nuclei in three merging galaxies has been discovered using two radio telescopes: the VLA and the VLBA. The triple system is cataloged as J1218/1219+1035. This targeted study, conducted by a team of researchers at various radio frequencies, has identified only the third case of a triple active galactic nucleus, the first confirmed through radio observations.

Here we have the "Champagne Cluster," which is two galaxy clusters in the process of merging

Is it giving you #NYE vibes???

From source linked in toot: The cluster appears here as a large collection of brilliant white lights, each a distinct galaxy. A neon purple cloud stretches across the cluster's crowded core. Many of the hundred-plus galaxies in the cluster are in two clumps of galaxies towards the top and bottom of center. Some are encircled by a faint glowing haze, while a few foreground stars gleam with diffraction spikes. Some of the smaller galaxies are tinted blue, orange, or red, and some appear more oblong than round, suggesting spiral shapes viewed edge-on.

The neon purple cloud sits at the heart of the image, surrounding the most densely-packed part of the cluster. This cloud, which spreads vertically across the cluster, is multimillion-degree gas observed by Chandra. The two clumps of observable galaxies, and the spread of superheated gas, reveal that the Champagne Cluster is in fact two clusters in the process of colliding.

With the two clusters of sparkling light clinking together, and the auspicious discovery date, astronomers have dubbed the merged cosmic structure "The Champagne Cluster".

14 #galaxies 🌌 in a line measuring about 5.5 million ly in length and roughly 117,000 ly across within a cosmic filament that stretches about 50 million ly and contains more than 280 additional galaxies appear to be rotating 🔁 in the same direction as the filament itself. Galaxies on opposite sides of the filament's central spine are moving in opposite 🔄 directions. This pattern indicates that the entire #filament is rotating as a single structure sciencedaily.com/releases/2025

Two-thirds of #galaxies 🌌 rotate clockwise 🔁. Either our entire #universe exists in a black hole, or #astronomers have been measuring the universe’s expansion incorrectly 🙈 smithsonianmag.com/smart-news/

Last images for tonight in the Odyssey Pro. Went to observe and . On the latter it seems the moonlight may have given it the haze in the image - or maybe not?

Galaxy NGC 0720 - telescope processed image. Its "egg-shaped" halo of hot X-ray gas provided key evidence that dark matter is real, as the gas would otherwise fly away.Galaxy NGC 0720 - unprocessed image. This "red and dead" galaxy is filled with very old stars, some nearly 13 billion years old, with almost no new star formation.Galaxy NGC 0925 - Telescope processed image. It is a "Magellanic" type spiral, meaning it is asymmetrical with a central bar that is strangely offset from its actual center.Galaxy NGC 0925 - unprocessed image. Located 30 million light-years away, it has a low surface brightness that makes it a challenging "ghostly" find for small telescopes.
