A fascinating study from the University of Chicago suggests that mini-Neptuns, the most common type of planet in our galaxy, could harbor vast water reserves in deep layers, completely invisible even to the advanced James Webb Space Telescope. This discovery changes our understanding of planetary formation.
An international team of scientists has identified the first stellar-mass black hole in Omega Centauri, the largest globular cluster in our galaxy. According to a study published in The Astrophysical Journal Letters, this historic discovery was made using over two decades of Hubble observations and recent James Webb data.
Un equipo internacional de astrónomos logró un hallazgo asombroso al analizar las huellas químicas del cometa interestelar 3I/ATLAS. Utilizando el Very Large Telescope de ESO, descubrieron que este viajero espacial, el más brillante jamás visto, se originó en un sistema estelar mucho más antiguo que nuestro Sol, abriendo una ventana sin precedentes hacia los orígenes de nuestra galaxia.
An international team led by the University of California has found 31 primordial quasars, two of which are record-breakers, using the Euclid space telescope. These bright objects, powered by supermassive black holes, radiated the light of a trillion suns when the universe was only 670 million years old, revealing fascinating secrets of the cosmos' dawn.
Located 2,000 meters above sea level in Chile, La Residencia serves as the home for astronomers and engineers of the European Southern Observatory. Featuring strict rules such as banning night lights and alcohol, this unique place allows guests to see the Magellanic Clouds with the naked eye and even served as a James Bond movie set.
Hidden in Chile's Atacama Desert, La Residencia serves as a unique oasis for scientists observing the cosmos. Known as a James Bond villain's lair on the big screen, this refuge combines extreme comfort with strict rules to protect one of the world's best night skies for astronomy.
An international team led by the University of Michigan has confirmed that interstellar comet 3I/ATLAS is up to 11 billion years old, more than double the age of our solar system. Published in Nature Astronomy, the discovery reveals record-breaking deuterium levels in its frozen water, proving it formed in an extremely cold, isolated environment before its own parent star even existed.
Located 57 light-years from Earth, GJ504b stands as one of the strangest celestial objects ever observed. The James Webb Space Telescope achieved what the largest ground-based observatories could not: revealing an atmosphere containing potassium chloride and zinc sulfide clouds—the first direct detection of such clouds on such a cold planetary body.
NASA has achieved an unprecedented image of the powerful jet of matter emerging from supermassive black hole M87*, the same cosmic giant that made history in 2019 as the first black hole ever photographed by humanity. This groundbreaking X-ray observation reveals new details about these mysterious phenomena that continue to challenge our understanding of the universe.
A South African radio telescope has captured a hydroxyl gigamaser located over 8 billion light-years away, establishing a new observation record of the early universe. The discovery, made in just five hours, allows scientists to observe colliding galaxies when the cosmos was less than half its current age.
El 13 de junio, el Planetario Galileo Galilei recibirá a Sara García Alonso, primera mujer española en la reserva de astronautas de la ESA, junto a Josefina Pérès (CONAE) y Susana Landau (CONICET). El encuentro gratuito está dirigido a jóvenes de 15 a 25 años y busca inspirar vocaciones científicas en áreas STEM.
La NASA confirmó que el 2 de agosto de 2027 se producirá el eclipse solar total más extenso del siglo, con una duración de 6 minutos y 23 segundos en su punto máximo. España será uno de los países privilegiados para observar este fenómeno astronómico histórico.
El desierto de Atacama alberga uno de los últimos cielos prístinos del planeta, donde astrónomos realizan descubrimientos cruciales sobre el universo. Sin embargo, la expansión industrial y urbana amenaza con destruir esta ventana al cosmos que tardó millones de años en revelarse.
El desierto de Atacama, uno de los últimos lugares del mundo con contaminación lumínica inferior al 1%, está perdiendo su oscuridad a un ritmo alarmante. Un estudio reveló que el cielo se iluminó un 10% anual entre 2011 y 2022, poniendo en riesgo a observatorios de clase mundial como Paranal y el futuro ELT.
La contaminación lumínica amenaza uno de los últimos lugares verdaderamente oscuros del planeta, donde astrónomos realizan descubrimientos cruciales sobre el cosmos. La industria minera y energética avanza hacia observatorios clave como Paranal, mientras científicos advierten que la humanidad está perdiendo su conexión con las estrellas.
Un equipo internacional de astrónomos logró medir por primera vez un agujero negro inactivo a 10.000 millones de años luz gracias al telescopio James Webb y una lente gravitacional natural. El hallazgo supera por 15 veces el récord anterior de distancia y abre una ventana inédita al universo primitivo.
Un aficionado a la astrofotografía logró immortalizar nada menos que 548 galaxias sin salir de su hogar. La imagen, tomada desde un simple balcón, demuestra que el universo está más cerca de lo que imaginamos. Un logro que inspira a miles de entusiastas de la astronomía en todo el mundo.
