JUICE Captures 120 Images of Interstellar Comet 3I/Atlas as It Recedes

ESA’s JUICE mission photographed interstellar comet 3I/Atlas in more than 120 JANUS images on November 6, 2025, a week after its closest approach to the Sun. The shots show a bright coma and a long tail, and scientists are analyzing the data (with results expected in late March). 3I/Atlas, discovered June 2025 by ATLAS, is only the third known interstellar visitor, and as it drifts away from the Sun, JUICE continues its deep-space observations on its way to Jupiter (arrival in 2031).

Orbital 'ring of fire' eclipse: Proba-2 captures four space-view angles of Feb. 17, 2026

ESA’s Proba-2 satellite recorded four viewpoints of the Feb. 17, 2026 annular solar eclipse from orbit, including a spectacular “ring of fire” when about 93% of the Sun was obscured; the SWAP instrument imaged the Sun’s corona in extreme ultraviolet, with the most complete ring visible from remote Antarctica while other locations saw a partial eclipse.

Space View Captures Ring-of-Fire Eclipse

ESA’s Proba-2 spacecraft photographed an annular solar eclipse on 17 February 2026, showing a ring of fire as the Moon sat near apogee. The view from space accompanied Earth observations mainly from Antarctica, with partial sights in southern Chile/Argentina and southern Africa. ESA also notes three more European eclipses expected between 2026 and 2028.

ISS Crew 12 to Join Station Ahead of Schedule, Replacing Crew 11

Crew 12—NASA’s Jessica Meir, Jack Hathaway, ESA’s Sophie Adenot, and Roscosmos’ Andrey Fedyaev—are set to launch on a SpaceX Falcon 9 from Cape Canaveral and dock with the ISS on Thursday, replacing Crew 11 who returned early due to a medical issue. The addition will bring the station to seven crew members and restore two-person NASA spacewalk capability. The flight was moved up after Artemis II was delayed, with the crew in quarantine at the Kennedy Space Center during preflight preparations.

ESA choreographs Cluster satellites for rare reentry observations

ESA choreographs Cluster satellites for rare reentry observations

ESA is adjusting the trajectories of its Cluster satellites Samba and Tango so they re-enter the Earth’s atmosphere in close succession (Aug. 31 and Sept. 1, 2026) over a remote South Pacific region, enabling observations from a plane to capture rare data on how they heat, break up, and survive reentry. This data will improve reentry models and guide the design of safer, “design-for-demise” satellites. The effort builds on the 2024 Salsa observation and aims to inform a future Draco mission (2027) that will image reentry from the inside, contributing to safer space debris disposal and better predictive capabilities.

ESA’s MTG-S1 Unveils High-Resolution Atmospheric Maps from Space

ESA's Meteosat Third Generation-Sounder 1 (MTG-S1) satellite, launched to a geostationary orbit above the equator, uses infrared sounding to produce near real-time temperature and humidity maps of Earth's atmosphere, offering data every 30 minutes over Europe and North Africa and enabling enhanced 3D atmospheric analysis to improve forecast accuracy and early warnings for severe storms as part of a six-satellite MTG program.

AI uncovers 800+ hidden cosmic anomalies in Hubble archive

ESA researchers trained a neural network called AnomalyMatch to sift through nearly 100 million image cutouts from the Hubble Legacy Archive in about 2.5 days, flagging 1,400 potential anomalies. After human review, more than 800 of these were undocumented, including merging galaxies, gravitational lenses, planet-forming disks seen edge-on, and other unusual objects, showcasing AI’s power to process vast astronomical datasets while still requiring expert confirmation.

Biomass satellites frees its data stream to illuminate global forest carbon

ESA’s Biomass, a P-band radar satellite launched in 2025, has completed commissioning and now offers free, public access to its data to map forest structure and carbon storage. The mission begins with an 18-month global tomographic coverage, followed by multiple nine-month interferometric coverages to monitor forest change over time, with an airborne calibration campaign in Gabon aiding data validation and calibration. The effort aims to reduce uncertainties in global forest carbon stocks and support climate science and forest management.

Sentinel-2A Captures Earth After Dark in Nighttime Imaging Trial

ESA’s daylight-focused Sentinel-2A was activated during night passes and produced unexpectedly clear images of gas flares in Qatar and Iraq, a wildfire in India, and fishing boats off South Korea, demonstrating potential for nighttime Earth observation and informing future mission requirements as the Copernicus program progresses with additional Sentinel-2 satellites.
