Extraordinary image of #comet #C2025A6 #Lemmon taken this morning from Observatori de Pujalt, l'Anoia, #Catalunya Great expectations for having it next month as a naked eye object! My outreach article gives clues on how observing it. Already it is noticeable using binoculars #PlanetSci

I EDITED THIS ARTICLE: "Local-NPDR: a novel variable importance method for explainable #MachineLearning and false discovery diagnosis for ocean worlds biosignatures" by Lily A. Clough et al. Published now in @Frontiers #AstronomySpaceSci #Astrobiology #PlanetSci www.frontiersin.org/journals/ast...

A must read. It takes years to see a spark transformed to a groundbreaking treatment. It all begins with basic research. Due to sustained #NIH funding, we have better therapeutics, cancer detection, vaccines. We are like 1930s Germany. 🧪 www.infotimes.us/basic-scienc... via @markhisted.org

Finished spread! The lives of different types of stars, the various ways they give back all they had taken in changed, and the new forms they give rise to! This took me some time to say the least! It's a lively place out there! On to the next spread (finale of this chapter!!) #Nostos #Unflattening 2

Saturn was at opposition last night. I imaged Titan and its shadow crossing the disk the night before. Here I show that image with an image of Saturn with Titan's shadow on the disk on Sept 4. Note how much brighter the ring is on the 20th. This is the Seeliger Effect. #astrophotography 🔭🧪

2 new #comets will be focusing our attention next weeks, and particularly #C2025A6 Lemmon will be a naked-eye object on late October. My new outreach article in Conversation.es can be easily translated to your favourite language, and hopefully useful to find them theconversation.com/dos-nuevos-c...

@mhairireid.bsky.social and I put together an article for @theconversation.com about yesterday's @nature.com paper on the detection of a 600 km radius solid core in the interior of #Mars! 🧪🔭 #planetsci Early InSight results didn't quite have the sensitivity for this! doi.org/10.64628/AB....

As Comet 3I/ATLAS passes Mars, European Space Agency plans to observe it using spacecraft orbiting the planet. Both Mars Express & ExoMars Trace Gas Orbiter will turn their instruments to gaze upon the comet.. We armchair astronauts had speculated; glad to see it become real. 🔭 #planetaryscience

Our galaxy is full of clouds of dust and gas. We can guess that they probably move, but it's hard to tell for sure. Until now! A groundbreaking new paper by Martin Piecka et al. at @univie.ac.at presents the first *ever* direct measurement of the proper motion of the ISM! 🔭☄️🧪 #galactic

New research revealed that Mars' innermost core appears to be a solid hunk of metal just like Earth's. @umdgeology.bsky.social's Nick Schmerr weighed in on these findings with @sciencex.bsky.social, noting that questions regarding Mars' core are far from settled. 🔭 #PlanetaryScience

Tras las muchas especulaciones sobre la naturaleza del objeto interestelar 3I/ATLAS, se confirma que se trata de un cometa que procede del espacio exterior. Nos cuenta más @joseptrigo.bsky.social (@ice-csic.bsky.social @ieec.cat):

Ceres, un mundo mucho más interesante de lo que podríamos haber soñado. Y quizás también más habitable.
