I had the pleasure of presenting our work on #asteroid #Kamoʻoalewa at #EPSC2026 on Monday. Is Earth’s unusual quasi-satellite a fragment of the Moon, or an asteroid delivered from the main belt? Our results strongly favour the latter. Here is the summary in one picture 👇

cutting pure science to prioritize applications is fundamentally like asking farmers not to waste time producing grain, cheese, and tomatoes and focus on making pizzas

Las clases del curso de Experto Universitario de #Astroinformática (#eupt_unizar) es tan diferente que hoy se ha impartido en el #ObservatorioAstrofísico de #Javalambre 🔭 ✨Así se aprende muy rápido cómo es el espejo principal de un telescopio 🪞 Y eso que solo llevan dos semanas 🚀...

Este miércoles vamos a tener nuevos datos, muy reveladores y alarmantes, sobre el impacto de las constelaciones de satélites. No puedo comentar más porque el trabajo está embargado pero estoy preparando unas declaraciones para varios medios de comunicación.

An #asteroid passed just 300 km above Antarctica earlier today. It was not discovered until hours after close approach.

Tomorrow, newly-discovered #asteroid 2025 RJ2 will miss the Moon by 13,000 km. Shortly before close approach, it will pass through the Moon's shadow.

weyWHAT An unexpected occultation discovery of a potential 2nd moon or 3rd ring arc around dwarf planet Quaoar! The new moon/ring is 30±2 km wide and seems to be 5757 km from Quaoar—suspiciously close to 7:2 orbital resonance with Quaoar's big moon Weywot! iopscience.iop.org/article/10.3... ☄️

We already have a winner for scientific figure of the month! Thanks to Rogerio Deienno for pointing out this paper. Carrie Nugent et al., Placing the Near-Earth Object Impact Probability in Context arxiv.org/abs/2508.02418

The chance of a > 140m NEO impacting Earth placed in context with the chance that other preventable events may happen to an individual. Individual event frequency and fatality chances are taken from peer reviewed studies on particular regions over specific time intervals; these are broad averages, individual risks vary widely. We expect most readers to be able to identify some events that are relevant to their lives, and some that are not. Readers interested in their own chances are
encouraged to consider the events most relevant to their demographics, geographic region, and hobbies. ...This figure is intended to contextualize the > 140m NEO impact frequency with events people may be familiar with, such as flu sickness and lightning strikes. The x-axis is the chance of the rare event happening to the planet (NEO impact) or an individual (all other events) over an average human lifetime. The y-axis shows the chance of fatality to an individual if the event occurs. The chance of fatality from a > 140m impact is dependent on a large range of variables,
such as impactor size (140 m to > 10 km) and impact location (populated city to middle of a large ocean). An impact could result in no fatalities (less likely) some fatalities (more likely) or mass extinction (very unlikely, but possible; this is represented by large error bars (blue).
