A search for variable stars called RR Lyrae has found some of the most distant stars in the Milky Way’s halo a million light years away. By Tim Stephens Santa Cruz, CA, Jan 26, 2023.- Astronomers have discovered more than 200 distant variable stars known as RR Lyrae stars inContinuar Leyendo
Interstellar molecular clouds are considered to be the birth sites of planetary systems. With the help of the James Webb Space Telescope, an international research team including the Center for Space and Habitability (CSH) at the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS discoveredContinuar Leyendo
París, Jan 15, 2023.- Two teams of astronomers using ESA’s XMM-Newton space telescope have observed repeated outbursts of light from inactive black holes that partially destroy stars again and again. This discovery is unexpected, since outbursts of black holes usually appear only once when a black hole consumes a star.Continuar Leyendo
NGC 346, one of the most dynamic star-forming regions in nearby galaxies, is full of mystery. Now, though, it is less mysterious thanks to new findings from the NASA/ESA/CSA James Webb Space Telescope. París, Jan12, 2023.- NCG 346 is located in the Small Magellanic Cloud (SMC), a dwarf galaxy closeContinuar Leyendo
Researchers have confirmed the presence of an exoplanet, a planet that orbits another star, using the NASA/ESA/CSA James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter. París,Continuar Leyendo
A myriad of stars is revealed behind the faint orange glow of the Sh2-54 nebula in this new infrared image. Located in the constellation Serpens, this stunning stellar nursery has been captured in all its intricate detail using the Visible and Infrared Survey Telescope for Astronomy (VISTA) based at ESO’sContinuar Leyendo
Photochemistry is common in our own Solar System and crucial to Earth’s atmospheric makeup, as well as to fundamental life processes such as photosynthesis. Washington, DC, Dec 29, 2022.- JWST has captured the first-ever evidence of a compound in the atmosphere of an exoplanet—sulfur dioxide—created by a starlight-mediated chemical reaction.Continuar Leyendo
París, Dec 23, 2023.- This is the antenna that will transmit back the first close-up images of the distant Dimorphos asteroid since its orbit was shifted by a collision with NASA’s DART spacecraft. The 1.13-m diameter High Gain Antenna of ESA’s Hera mission went through a week-long test campaign atContinuar Leyendo
Webb’s picture of the month December is dominated by NGC 7469, a luminous, face-on spiral galaxy approximately 90 000 light-years in diameter that lies roughly 220 million light-years from Earth in the constellation Pegasus. París, December 22, 2022.- This spiral galaxy has recently been studied as part of the GreatContinuar Leyendo
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
