  3. CFHT SITELLE image of Arp 82, also known as NGC 2535 and NGC 2536.

    Simulations suggest the two galaxies are in the early stages of a merger. The merger began about 40 million years ago, and the galaxies already experienced one collision and are just about to experience a second. The merger should be complete in another 450 million years.

  5. ☀️ The Sunrise III mission – a balloon-borne solar observatory involving the Max Planck Institute – offers a brand-new view of the Sun. First results reveal oscillations, flares and "tornadoes" in the solar atmosphere at unprecedented resolution.

  6. 🌑 Get involved! A citizen science project is collecting observations of "shadow bands" during the total solar eclipse of 12 Aug 2026 over Iceland and Spain. Volunteers will help reveal how location and altitude shape these fleeting ripples seen seconds before totality.

  7. 🌠 Gaia lives on in its data: ESA has released Gaia Bulletin #08 (3 Jul 2026) with updates for users of the mission's open archive, which precisely mapped over a billion Milky Way stars. The main Gaia DR4 catalogue – from the first 5.5 years of observations – arrives 2 Dec 2026. A treasure trove of open astronomical data for everyone. (3 Jul 2026)

  9. 🛰️ A new ESO study warns that the planned 1.7 million satellites would have 'devastating' consequences for astronomy. Bright megaconstellations would brighten the night sky and leave trails across up to 28% of the VLT's field of view. No more than 100,000 faint satellites should orbit Earth. (2 Jul 2026)

  11. 🌌 The Sloan Digital Sky Survey has launched Data Release 20: over 3 million spectra of stars and galaxies, 18 new value-added catalogues and, for the first time, optical spectra from the Southern Hemisphere. Free and not just publicly available but publicly usable, with tutorials for all. (30 Jul 2026)

  13. Radio astronomy: the most sensitive search yet for technosignatures from exoplanet K2-18b. The VLA and MeerKAT radio telescopes watched the system for 33 days (a full planetary "year") across 544 MHz–9.8 GHz. No artificial signals were found, but the team demonstrated a faster method for future SETI surveys.

  14. Data science in meteor studies: a new paper models the dynamical origin of millimetre-sized sporadic meteoroids — the particles that deliver most of the mass flux hitting Earth. The analysis (Dao, Brown, Pokorný) builds on open data from meteor radars and video networks. Published in eMetN's Meteor Library.

  19. "How engineers plan to save the satellite sent to save NASA’s Swift mission" by @arstechnica / Stephen Clark - #NASA satellite vendor Katalyst is slowly stabilizing Link satellite. Slow but long-duration ion thrusters have cut spin rate in half, and continue. Incident still under investigation: many systems failed at once. Once stable, they can get more data to sort out cause from effect, and use cameras to check if anything collided with it. arstechnica.com/space/2026/08/ #astronomy #space #science

  22. Image of Arp 94, also known as NGC 3226 and NGC 3227, from the Atlas of Peculiar Galaxies by Halton Arp (1966).

    In the original catalog, it was in the category: Spiral galaxies - Elliptical companions. The large spiral galaxy, NGC 3227 is interacting with its elliptical galaxy companion, NGC 3226. Faint tidal streams of gas and dust link the pair, showing evidence of their mutual gravitational tugs.
