  4. Since it's getting misreported everywhere: this image of the stellar stream of the #galaxy #Messier61 by #Rubin - from A #StellarStream around the Spiral Galaxy Messier 61 in Rubin First Look Imaging: iopscience.iop.org/article/10. - is the *best* but not the first. For it had already been imaged, often clearly, by #AmateurAstronomers in 2020, 2024 and earlier in 2025: flickr.com/photos/133259498@N0 and galactic-hunter.com/post/messi and app.astrobin.com/i/0az5qv and app.astrobin.com/i/ldptvo - and these are just the results I could track down easily.

  5. In the arXiv today, discovery of the Giant Coma Stream, a ~500 kpc extremely faint and thin stellar stream in the Coma cluster of galaxies. Such objects probe the local gravitational potential and could help unveiling the ultimate nature of dark matter.

  6. A giant thin #StellarStream in the #Coma #GalaxyCluster: arxiv.org/abs/2305.03073 - "an extremely faint stellar stream (mu_g,max = 29.5 mag arcsec-2) with an extraordinarily coherent and thin morphology in the Coma Galaxy Cluster. This Giant Coma Stream spans 510 kpc in length and appears as a free-floating structure located at a projected distance of 0.8 Mpc from the center of Coma. [...] We interpret the Giant Coma Stream as being a recently accreted, tidally disrupting dwarf of M* ~10^8 Msun."
