Europe’s latest Galileo satellites in space have joined the operational constellation, transmitting navigation signals to three billion users across planet Earth as well as relaying distress calls to rescuers. Their entry into service follows a summer test campaign and will result in a measurable increase in positioning accuracy and improvedContinuar Leyendo
Webb demonstrates its spectroscopic power with the first unequivocal detection of carbon dioxide in a planetary atmosphere outside the Solar System. París, August 25, 2022.- The NASA/ESA/CSA James Webb Space Telescope has found definitive evidence for carbon dioxide in the atmosphere of a gas giant planet orbiting a Sun-like starContinuar Leyendo
A new map of Mars is changing the way we think about the planet’s watery past, and showing where we should land in the future. París, August 22, 2022.- The map shows mineral deposits across the planet and has been painstakingly created over the last decade using data from ESA’sContinuar Leyendo
Chicago, August 17, 2022.- A black hole is usually where information goes to disappear — but scientists may have found a trick to use its last moments to tell us about the history of the universe. In a new study, two University of Chicago astrophysicists laid out a method forContinuar Leyendo
In 2019, NASA’s OSIRIS-REx spacecraft sent back images of a geological phenomenon no one had ever seen before: pebbles were flying off the surface of the asteroid Bennu. The asteroid appeared to be shooting off swarms of marble-sized rocks. Scientists had never seen this behavior from an asteroid before, andContinuar Leyendo
Astronomers have long sought the launch sites for some of the highest-energy protons in our galaxy. Now a study using 12 years of data from NASA’s Fermi Gamma-ray Space Telescope confirms that one supernova remnant is just such a place. Greenbelt, MD, August 13, 2022.- Fermi has shown that theContinuar Leyendo
París, August 03, 2022.- On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concertedContinuar Leyendo
Webb’s Instruments Reveal New Details About Star Formation and Black Holes. París, August 02, 2022.- The Cartwheel Galaxy, a rare ring galaxy once shrouded in dust and mystery, has been unveiled by the imaging capabilities of the NASA/ESA/CSA James Webb Space Telescope. The galaxy, which formed as a result of aContinuar Leyendo
About three years ago, Wolfgang «Wolfi» Mittig and Yassid Ayyad went looking for the universe’s missing mass, better known as dark matter, in the heart of an atom. East Lansing, July 24, 2022.- Their expedition didn’t lead them to dark matter, but they still found something that had never beenContinuar Leyendo
A team of astronomers has developed a method that will allow them to ‘see’ through the fog of the early Universe and detect light from the first stars and galaxies. Cambridge, July 22, 2022.- The researchers, led by the University of Cambridge, have developed a methodology that will allow themContinuar Leyendo
