Tras la cuenta atrás en francés de diez a uno, se anuncia: «Décollage»: despegue. La colaboración de 15 años entre la NASA, la ESA y la Agencia Espacial Canadiense (CSA) acababa de entrar en su fase más crítica: el lanzamiento. Lo que sucediera posteriormente determinaría si el telescopio espacial JamesContinuar Leyendo
Researchers have found evidence for the existence of a new type of planet they have called a “water world,” where water makes up a large fraction of the entire planet. These worlds, discovered in a planetary system 218 light-years away, are unlike any planets in our Solar System. París, DecemberContinuar Leyendo
Ha finalizado la primera misión lunar Artemis. La nave Orion de la NASA ha amerizado en el océano Pacífico a las 17:40 GMT/18:40 CET, después de haber orbitado por el satélite y de haberse adentrado en el espacio más que ninguna otra nave diseñada para transportar personas, para luego volverContinuar Leyendo
Astronomers have determined the source of an incredibly bright X-ray, optical and radio signal appearing from halfway across the Universe. Birmingham, Dec 09, 2022.- The signal, named AT 2022cmc, was discovered earlier this year by the Zwicky Transient Facility in California. Findings published today in Nature Astronomy, suggest that itContinuar Leyendo
A contract signed today between ESA and Arianespace has ensured rides into orbit for five Copernicus Sentinels: Sentinel-1D, Sentinel-2C, Sentinel-3C, and the Copernicus Anthropogenic Carbon Dioxide-A and -B satellites. All the satellites will be launched on Vega-C rockets from Europe’s Spaceport in French Guiana and are scheduled to take placeContinuar Leyendo

The impact experiment conducted on the asteroid Ryugu by the Japanese Hayabusa2 mission which took place two years ago resulted in an unexpectedly large crater. With the use of simulations, a team led by the University of Bern and the National Center of Competence in Research (NCCR) PlanetS has recentlyContinuar Leyendo
An international team of astronomers have turned a new technique onto a group of galaxies and the faint light between them — known as ‘intra-group light’ — to characterise the stars that dwell there. Sydney, Nov 27, 2022.- Lead author of the study published in MNRAS, Dr Cristina Martínez-Lombilla fromContinuar Leyendo
