For the first time ever, astronomers have imaged in real time the dramatic end to a red supergiant’s life — watching the massive star’s rapid self-destruction and final death throes before collapsing into a type II supernova. Evanston, Jan 07, 2022.- Led by researchers at Northwestern University and the UniversityContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope team has fully deployed the spacecraft’s sunshield in space, a key milestone in preparing it for science operations. The sunshield – about the size of a tennis court at full size – was folded to fit inside the Ariane 5 rocket’s nose cone priorContinuar Leyendo
NASA’s James Webb Space Telescope launched at 7:20 a.m. EST Saturday on an Ariane 5 rocket from Europe’s Spaceport in French Guiana, South America. Washington, Dec 26, 2021.- A joint effort with ESA (European Space Agency) and the Canadian Space Agency, the Webb observatory is NASA’s revolutionary flagship mission toContinuar Leyendo
Vienna, Dec 23, 2021.- Rogue planets are elusive cosmic objects that have masses comparable to those of the planets in our Solar System but do not orbit a star, instead roaming freely on their own. Not many were known until now, but a team of astronomers, using data from severalContinuar Leyendo
Krypton from the Earth’s mantle, collected from geologic hot spots in Iceland and the Galapagos Islands, reveals a clearer picture of how our planet formed, according to new research from the University of California, Davis. Davis, CA, December 17, 2021.- The different isotopes of krypton are chemical fingerprints for scientistsContinuar Leyendo
París, December 15, 2021.- “We want to learn more about the black hole at the centre of the Milky Way, Sagittarius A*: How massive is it exactly? Does it rotate? Do stars around it behave exactly as we expect from Einstein’s general theory of relativity? The best way to answerContinuar Leyendo
By performing a series of real and ‘fake’ flybys, ESA’s Mars Express has revealed how Mars’ largest moon, Phobos, interacts with the solar wind of charged particles thrown out by the Sun – and spotted an elusive process that has only been seen at Phobos once before. París, The solarContinuar Leyendo
Data from ESA’s Gaia mission is re-writing the history of our galaxy, the Milky Way. What had traditionally been thought of as satellite galaxies to the Milky Way are now revealed to be mostly newcomers to our galactic environment. París, Nov 24, 2021.- A dwarf galaxy is a collection ofContinuar Leyendo
París, Nov 19, 2021.- Solar Orbiter is returning to Earth for a flyby before starting its main science mission to explore the Sun and its connection to ‘space weather’. During the flyby Solar Orbiter must pass through the clouds of space debris that surround our planet, making this manoeuvre theContinuar Leyendo
The world will be watching the milestone launch of NASA’s Double Asteroid Redirection Test, DART, spacecraft on Wednesday, 24 November, intended to alter one small part of the Solar System forever. París, Nov 18, 2021.- DART will collide with the small moon of an asteroid in order to shift itsContinuar Leyendo
