🌊 Open European Earth data gets easier to reach: registered Copernicus Marine Service users can now log in to Copernicus Data Space (including the Copernicus Browser) with their existing credentials, and vice versa. No second account, same rights. More federated services may follow. CDSE, 12 Oct […]

🛰️ New openEO community example from Copernicus Data Space: the notebook “Coherence for harvest days” builds a Sentinel-1 (VH) coherence time series and flags fields where coherence jumps, a likely harvest. Radar sees through clouds; results should be checked against field data. CDSE, 14 Oct […]

🛰️ Copernicus Sentinel-5P gets a new processing baseline on 10 Nov 2026: improved NO2, methane, ozone, SO2 and formaldehyde products, plus a new random-forest cloud mask for aerosol layer height. Open European air-quality data will become more accurate. Copernicus Data Space, 13 Oct 2026. 🔗 […]

🔭 Open archives pay off: PhD student Jamie Williams (Univ. of Warwick) re-examined 1999 Hubble data of the white dwarf HS 0209+0832 with an updated line database and found unusually strong niobium. With FUSE and TESS data it points to a gas giant losing its atmosphere. Nature Astronomy, 5 Oct […]

🤖 Amalia, the full-size twin of the Rosalind Franklin rover, rehearsed driving off the lander platform in Turin (ALTEC, Thales Alenia Space): 20+ runs in two months, with Mars-like gravity (~1/3 of Earth’s), a 20° tilt and obstacles under the ramps. The rover’s Mars journey begins in 2030. ESA […]

📖 The Open Journal of Astrophysics (diamond open access – free for authors and readers) published eight new papers on 5–9 Oct 2026; volume 2026 now holds 237 papers, 685 in total. Among them: radii and temperatures of 27 nearby stars measured with the CHARA Array. Weekly update, 10 Oct 2026. 🔗 […]

🔭 Galaxy Zoo “What the Shell?” is building the first-ever catalogue of shell galaxies across the Universe – with help from volunteers. Astrophysicist Tom Donlon (Univ. of Minnesota) studies the Milky Way’s structure and what it reveals about dark matter. “Who’s who in the Zoo”, Zooniverse blog […]

📡 ESA and the IAU Centre for the Protection of the Dark and Quiet Sky (IAU CPS) signed a Memorandum of Intent to develop technical solutions that reduce satellite impacts on astronomy. Spacecraft electronics can emit unintended radio signals that interfere with sensitive radio telescopes. Signed […]

☄️ Koen Miskotte (CAMS Benelux) reports seven July nights of visual meteor observing from the Netherlands in eMetN: about 164 meteors, the first possible Perseid on 12/13 Jul and a bright sporadic fireball (~−4 mag) on 20/21 Jul also caught by an all-sky camera. A nice example of amateur data […]

🧲 ESA has released updated magnetic datasets from CryoSat-2 (May 2010 – Aug 2026, new data added monthly) and GRACE-FO (2018–2023, 2 Hz) on the Swarm dissemination server. Calibrated with the CHAOS-8.6 model – open data for geomagnetic research. 📅 1 Oct 2026 🔗 […]

☀️ Solar Orbiter flew through a large “switchback” – an S-shaped kink in the solar wind's magnetic field. The mix of charged oxygen and carbon ions shows it formed in hot magnetic loops on the Sun's surface (interchange reconnection). Published in Nature Astronomy. 📅 8 Oct 2026 🔗 […]

📡 The MeerKAT radio telescope caught fast radio burst FRB 20240304B, and Webb then pinned down its host galaxy: z=2.148, the most distant localized FRB yet. The host is a small, young galaxy – pointing to a magnetar origin rather than a neutron-star merger. 📅 8 Oct 2026 🔗 […]

🛰️ Copernicus Data Space Ecosystem introduced the “openEO Agent”: an AI assistant that turns plain-language questions into validated openEO workflows over open Sentinel data. It shows the process chain for approval, submits the batch job and reads the logs if it fails. Limited access for now […]

📡 September 2026 in radio meteors: Felix Verbelen at Kampenhout (Belgium) monitors reflections from the 49.99 MHz beacon. He logged 20 long echoes (>1 min) over the month; the standout day was 15 Sep (solar longitude 172°). Raw counts are available as CSV. (4 Oct 2026) […]

📡 Beyond citizen science: a study for the book "Advancing Astrophysics with the SKA II" models how the future Square Kilometre Array could use radio auroral emission to detect magnetic fields on exoplanets and ultracool dwarf stars - building on this year's radio detection from Beta Pictoris b […]

☄️ Open data at work: the Global Meteor Network (732 cameras, 34 countries) helped solve a meteor-shower puzzle. Analysing 280,307 orbits from 2019-2026, researchers found the tau-Cetids are just an early phase of the eta-Eridanids, sharing the same parent comet C/1852 K1 (Chacornac). They […]

🌟 HOYS's "Lightcurve of the week" #402 features young binary PR Ori, just south of the Orion Nebula. Component A is itself a binary; component B recently went through an FU Ori-type outburst. The plot is built from ten years of B, V, R, I photometry gathered by HOYS citizen-science volunteers […]
