An intermediate-mass black hole lurking undetected in a dwarf galaxy revealed itself to astronomers when it gobbled up an unlucky star that strayed too close. The shredding of the star, known as a «tidal disruption event» or TDE, produced a flare of radiation that briefly outshone the combined stellar lightContinuar Leyendo
París, November 14, 2022.- Solar Orbiter has spotted a ‘tube’ of cooler atmospheric gases snaking its way through the Sun’s magnetic field. The observation provides an intriguing new addition to the zoo of features revealed by the ESA-led Solar Orbiter mission, especially since the snake was a precursor to aContinuar Leyendo
People who have a past history of hospitalisation because of substance use disorders have much worse outcomes following the onset of a wide range of physical health conditions, according to researchers in the UK and Czechia. Cambridge, November 11, 2022.- In a study published today in The Lancet Psychiatry, researchersContinuar Leyendo
ESA’s Mars Express spacecraft recently conducted tests in which it relayed data gathered by NASA’s Perseverance rover back to Earth. The 19-year-old spacecraft has now relayed data for seven different Mars surface missions – a unique, new record! Parìs, November 10, 2022.- Landers and rovers on Mars gather data that helpContinuar Leyendo
With the use of a precision experiment developed at the University of Bern, an international research team has succeeded in significantly narrowing the scope for the existence of dark matter. The experiment was carried out at the European Research Neutron Source at the Institute Laue-Langevin in France, and makes anContinuar Leyendo
By Blaine Friedlander, Cornell Chronicle Ithaca, November 09, 2022.- Nearly 175 community members joined a town forum Nov. 3, held in person and online, to hear updates on the Cornell University Borehole Observatory – known as CUBO. The observatory represents a major step toward achieving viability for the university’s EarthContinuar Leyendo
Three different moments in a far-off supernova explosion were captured in a single snapshot by the NASA/ESA Hubble Space Telescope. The progenitor star exploded more than 11 billion years ago, when the Universe was less than a fifth of its current age of 13.8 billion years. París, November 09, 2022.-Continuar Leyendo
A new model that accounts for the interplay of forces acting on newborn planets can explain two puzzling observations that have cropped up repeatedly among the more than 3,800 planetary systems cataloged to date. Houston, November 07, 2022.- One puzzle known as the «radius valley» refers to the rarity ofContinuar Leyendo
Visual signals, such as color patterns are an important communication medium for anemonefish. Researchers from Okinawa Institute of Science and Technology have recently elucidated how the patterns on anemonefish—which are conspicuous white bars against an orange, red, or black background—influence their aggressive behavior and possibly determine the color patterns ofContinuar Leyendo
As heart cells mature in mice, the number of communication pathways called nuclear pores dramatically decreases, according to new research from University of Pittsburgh and UPMC scientists. While this might protect the organ from damaging signals, it could also prevent adult heart cells from regenerating, the researchers found. Pittsburgh, NovemberContinuar Leyendo
