With characteristic disregard for science and technology the Australian government has decided that Australia will not become a full member of the European Southern Observatory (@esoastronomy) when the current interim Strategic Partnership arrangement expires at the end of 2027.
This leaves the […]

A black-and-white composite image showing the four Galilean moons of Jupiter side by side against a black background, each shown in half-phase illumination. From left to right: Io, with a heavily marked and volcanic surface; Europa, with a smooth surface crossed by faint linear fractures; Ganymede, the largest, showing a mix of dark ancient terrain and brighter grooved regions with impact craters; and Callisto, heavily cratered across its entire surface.
🚨 New episode is out now!
In this episode, we visit each of the Galilean moons of Jupiter -- we recap the #mythology from prior episodes & share some fun #astronomical facts about each moon!
Listen here […]

A sliver of earth visible through the window of Artemis II.
“Artemis II Looking Back at Earth -
A view of Earth taken by NASA astronaut and Artemis II commander Reid Wiseman from one of the Orion spacecraft's four main windows after completing the translunar injection burn on April 2, 2026.”

Fotografía del disco solar completo en luz blanca tomada el 2 de julio de 2024 desde Madrid. El Sol aparece como una esfera dorado-amarillenta sobre fondo negro, con un suave oscurecimiento hacia el limbo que da sensación tridimensional. Se distinguen al menos dos grupos de manchas solares: uno grande y complejo situado ligeramente al sur del centro del disco, con múltiples umbras oscuras y poros visibles, y varios grupos menores dispersos cerca del limbo norte. Una mancha aislada es visible en el cuadrante suroeste. La textura de la fotosfera muestra un grano fino sutil, límite de la resolución alcanzable con este equipo. Captura: Olympus E-M1 Mark III + M.Zuiko 100-400mm a 400mm + teleconvertidor MC-14 (560mm f/9, equivalente a 1120mm) sobre montura ecuatorial Sky-Watcher Star Adventurer GTi, con filtro solar de seguridad. Vídeo MOV 4K (3840×2160) a 30fps, 95 Mbps, 1 minuto de captura (~1800 frames). Procesado: preprocesado en PIPP (centrado de disco, crop, selección del canal verde, descarte del 25% de peores frames), apilado por lucky imaging en AutoStakkert!4 (modo Surface, ~104 puntos de alineación, mejor 25% de frames), sharpening mediante deconvolución Lucy-Richardson y unsharp masking adaptativo en ImPPG, y acabado final con colorización y ajuste de contraste en PixInsight usando el módulo SolarToolbox.
He reprocesado mi imagen del sol de primeros de julio de 2024 y ahora me gusta ams y me he deshecho de la banda horrorosa de alrededor, creo que para mi promera y unica vez de fotografía solar y aprender a darle otra vuelta estoy muy contento :)

An image taken from the Orion spacecraft, showing part of the vehicle's structure on the left against a black background. To the right, Earth appears as a thin crescent, mostly in shadow with a bright blue-white illuminated sliver visible.

It's fun how, even as a pretty senior person, you end up in research projects with PhD candidates or postdocs who assume you an expert while you panicky try to read up on what you are working on and at least understand the basics enough to be able to follow and usefully contribute.
In other […]

A NASA illustration showing the Juno spacecraft and the Jovian system against a black background. A blue curved line traces Juno's orbital path as it arcs past Jupiter and its moons. From left to right, three of Jupiter's Galilean moons are shown in increasing size: Ganymede (gray and cratered), Europa (smooth and icy with a faint bluish tint), and Io (colorful with orange, yellow, and brown volcanic surface markings). Jupiter dominates the right side of the image, showing its characteristic tan and orange banded atmosphere and the Great Red Spot. The Juno spacecraft, with its three solar panel arrays, is visible in the upper center following its trajectory.
There's really only one way to come back from #hiatus / getting lost in the woods with Chiron
... coming Saturday!

"Given that the predictive power of science fiction is well established, we suggest that these locations might be prioritised by searches for extrasolar biospheres."
What an excellent paper by Elizabeth R Stanway from Warwick, never thoughts I'd see such an amazing collaboration between […]
