I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#New study questions decades of research on the evolution of spiral galaxies” Credit: ESO Previous studies on the formation and evolution of spiral galaxies might have been based on an incorrect assumption, suggests a team of researchers of Instituto de Astrofísica e Ciências do Espaço (IA). Most spiral galaxies are characterized by a disk, in…
“#Gas reaches young stars along magnetic field lines” Artistic impression of the hot gas streams that help young stars grow. Magnetic fields guide matter from the surrounding circumstellar disk, the birthplace of the planets, to the surface of the star, where they produce intense bursts of radiation. Credit: A. Mark Garlick Astronomers have used the…
“#Maunakea observatories discover three pairs of merging supermassive black holes” sdss j0847-0013, one of three, rare dual quasars discovered with three maunakea observatories. Credit: Silverman et al A cosmic dance between two merging galaxies, each one containing a supermassive black hole that’s rapidly feeding on so much material it creates a phenomenon known as a…
“#Continuous infrared winds discovered during the eruption of a stellar mass black hole” Artistic impression of the constant emission of winds produced during the eruption of a black hole in an X-ray binary. Credit: Gabriel Pérez Díaz, SMM (IAC). A team of researchers from the Instituto de Astrofísica de Canarias (IAC) has, for the first…
“#New observations of black hole devouring a star reveal rapid disk formation” This image from a computer simulation shows the rapid formation of an accretion disk during the disruption of a star by a supermassive black hole. Credit: Enrico Ramirez-Ruiz When a star passes too close to a supermassive black hole, tidal forces tear it…
“#AstroSat observations detect thermonuclear X-ray bursts on Cygnus X-2” The raw light curve of Cyg X-2. Credit: Devasia et al., 2020. Using the AstroSat spacecraft, Indian astronomers have identified thermonuclear X-ray bursts on the low-mass X-ray binary (LMXB) Cygnus X-2. The finding, reported in a paper published August 17 on the arXiv preprint server, could…
“#NASA missions explore a ‘TIE fighter’ active galaxy” This illustration shows two views of the active galaxy TXS 0128 554, located around 500 million light-years away. Left: The galaxy’s central jets appear as they would if we viewed them both at the same angle. The black hole, embedded in a disk of dust and gas,…
“#A galaxy’s stop-and-start young radio jets” Credit: Lister et al.; Sophia Dagnello, NRAO/AUI/NSF In this image, made with the National Science Foundation’s Very Long Baseline Array (VLBA), young, radio-emitting jets of material emerge from the core of an elliptical galaxy some 500 million light-years from Earth. After NASA’s Fermi Gamma-ray Space Telescope detected high-energy gamma…
“#Tracing the cosmic origin of complex organic molecules with their radiofrequency footprint” Scientists from Japan have found concluding evidence for the presence of a particular complex organic molecule in the regions of less dense gas clouds for the first time. Credit: Tokyo University of Science The origin of life on Earth is a topic that…
“#Recently discovered planets not as safe from stellar flares as first thought” Violent outbursts of seething gas from young red dwarf stars may make conditions uninhabitable on fledgling planets. In this artist’s rendering, an active, young red dwarf (right) is stripping the atmosphere from an orbiting planet (left). Credit: NASA, ESA and D. Player (STScI)…
