Visto el interés suscitado por el #MecanismodeAnticitera gracias a la última película de Indiana Jones, aquí os dejo el enlace a los siete capítulos que dediqué al Mecanismo en el programa de #UnPuntoAzul de mis amigos de la @magallanesjerez. https://t.co/lFSwAuXOuo

Full speed ahead to Apophis! 🚀🪨 ESA has awarded two contracts for the development of its Ramses mission, which will rendezvous with the asteroid Apophis ahead of its once-in-a-millennium flyby of Earth in 2029: https://t.co/nBHiydnODA

Menudo subidón que ha pegado el agua embalsada en España... claro, que no es de extrañar con todo lo que ha caído en estas semanas...

La Unión Astronómica Internacional (IAU) también ha querido tener voz en el asunto del 3I/ATLAS. Una página muy recomendable: https://t.co/wLoXmN2IhJ

Fun fact: we recently moved two satellites to meet a plane. Why? For valuable scientific data on atmospheric reentries. Find out more about the why & how 👉 https://t.co/OUdHV5upfw

ESA is closely monitoring a notable space weather event, first detected at 18:09 UTC on 18 January 2026. Aurora were observed over Europe last night and continued high levels of space weather activity are anticipated over the coming days. https://t.co/uwNsHZUmzg

Y ya a vuestra disposición, @astronomiamag de febrero.

In 2025, 10 asteroids were named after people and places associated with @esa's efforts to discover, monitor, explore and keep Earth safe from asteroids. Well done Planetary Defence team, you rock! 😉☄️ https://t.co/GzJct82l94

Manicouagan crater🇨🇦 from space. Also known as the 'Eye of Québec', this round structure was formed by a giant asteroid impact about 214 million years ago. Spanning 72 km from east to west, it's one of the oldest and largest impact craters on Earth. 📸@CopernicusEU

🐣 Found: newborn stars and planets @ESAGaia and @almaobs joined forces to study 31 baby star systems, finding hints of planets 👉 https://t.co/eckqR1yKJO The collage also shows our own Solar System for reference on the bottom right, as it is predicted to have looked at an age

📡 2025 marked a landmark year for #Estrack, ESA’s global network of ground stations. Since its inception in 1975, Estrack has formed a vital communication bridge between satellites in orbit and mission control at the European Space Operations Centre (ESOC).

¡Enhorabuena @J_MartinezFrias!

¡Vaya! Esto no lo conocía. El grandísimo James Clerk Maxwell no sólo estableció la teoría del electromagnetismo, sino que también demostró matemáticamente que los anillos de Saturno debían de estar compuestos de pedazos relativamente pequeños de material sólido.

Acabamos de lanzar nuestro boletín mensual, en el que hemos publicado una interesante estadística de descubrimiento de asteroides cercanos a la Tierra. El incremento en descubrimientos de los últimos años es alucinante. https://t.co/kvZ2W2p0cl

☄️ Our #ESAJuice team couldn't wait until February, when they will receive data on #3IATLAS from the mission's science instruments. So they downloaded just a quarter of an image from its navigation camera to get a surprise sneak preview. More info and annotations 👉

🌞🛰️Sun-watcher SOHO turns 30! 🎂 "SOHO has overcome nail-biting challenges to become one of the longest-operating space missions of all time" – Prof. @CGMundell, ESA Director of Science 👉 https://t.co/Oa5jlmaUNp 📷 SOHO (@esa & @NASA)

Para aquellos que queráis saber cómo se ha presupuestado el programa de seguridad espacial de la ESA para los próximos años: https://t.co/erY6EEhOz3

Ministers and high-level representatives from across Europe and from Canada kicked-off @ESA’s Council at Ministerial level in Bremen yesterday to define the Agency’s budget and programmatic priorities for the coming three years – decisions that will shape Europe’s role in space

Y gracias también a @asteroid7687, que fue codescubridor del asteroide. Vielen dank Matthias!
