A recently released set of topography maps provides new evidence for an ancient northern ocean on Mars. The maps offer the strongest case yet that the planet once experienced sea-level rise consistent with an extended warm and wet climate, not the harsh, frozen landscape that exists today. University Park, Pa.,Continuar Leyendo
When Mars’ first samples return to Earth, scientists should be on the lookout for ancient sleeping bacteria, a new study has found. Evanston, IL, October 26, 2022.- In a first-of-its-kind study, a research team, including Northwestern University’s Brian Hoffman and Ajay Sharma, found that ancient bacteria could survive close toContinuar Leyendo
Webb continues its search into the earliest times of our Universe, revealing the surprising formation of a massive galaxy cluster around a powerful, red quasar. Parìs, October 20, 2022.- Astronomers looking into the early Universe have made a surprising discovery using the NASA/ESA/CSA James Webb Space Telescope. Webb’s spectroscopic capabilities, combinedContinuar Leyendo
ESA’s Navigation Directorate is planning a new satellite whose results will enable the generation of an updated global model of Earth – the International Terrestrial Reference Frame, employed for everything from land surveying to measuring sea level rise – with an accuracy down to 1 mm, while tracking ground motionContinuar Leyendo
París, October 19, 2022.- The NASA/ESA/CSA James Webb Space Telescope has captured a lush, highly detailed landscape – the iconic Pillars of Creation – where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. TheseContinuar Leyendo
We have now discovered 30 039 near-Earth asteroids in the Solar System – rocky bodies orbiting the Sun on a path that brings them close to Earth’s orbit. The majority of these were discovered in the last decade, showing how our ability to detect potentially risky asteroids is rapidly improving.Continuar Leyendo
The kinetic impact of NASA’s DART spacecraft with the Dimorphos asteroid around its larger Didymos parent body has succeeded in shifting its orbit, meaning humankind’s first planetary defence test has been successful. Observations are continuing of the debris plume caused by the collision for as long as possible, as theContinuar Leyendo
París, Oct 12, 2022.- The ESA-led Solar Orbiter mission arrives at its next close approach to the Sun on 12 October 2022 at 19:12 UTC (21:12 CEST). This sequence of images shows the progress of the ESA/NASA spacecraft as it heads inwards on its voyage of discovery. The sequence beginsContinuar Leyendo
ESA’s flagship Ariane 6 launch vehicle programme has taken a dramatic step towards first flight with the start of a series of hot fire tests of the rocket’s upper stage and its all-new Vinci engine. Lampoldshausen, Oct 06, 2022.- These tests, which began on 5 October 2022, represent a significantContinuar Leyendo
Two of the great observatories, the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescope, have captured views of a unique experiment to smash a spacecraft into a small asteroid. NASA’s Double Asteroid Redirection Test (DART) impact observations mark the first time that Webb and Hubble were usedContinuar Leyendo
