Astronomers are now using the #JWST to scan the atmospheres of exoplanets within our galaxy for telltale chemical signatures of life, a process known as transmission spectroscopy. In early observations of the gas giant WASP‑39 b, Webb captured its infrared light during a transit

Dentro de un año, el 12 de agosto de 2026, tendrá lugar un eclipse de Sol que se verá como total en parte España. El máximo sucederá hacia las 20:30. Si planeas observarlo desde donde estás hoy, busca un buen lugar con vistas a la puesta de Sol. Más info: eclipses.ign.es/eclipse-total-…

En la madrugada del 12 de agosto 2025 a pesar de las nubes que no dejaron ver las Perseidas se pudo ver desde Boadilla del camino, Palencia la conjunción de Venus y Júpiter y también Mercurio muy débil cercano al horizonte. Con f 1200 mm se pueden ver los satélites de Júpiter

#HBD to arXiv!🎈 On August 14, 1991, the very first paper was submitted to arXiv. That's 34 years of sharing research quickly, freely & openly! Some baby pictures to show how far we've come . . . when we were just a computer under desk . . . & in our 1994 punk phase . . . 👶💾
