París, May 15, 2023.- The NASA/ESA/CSA James Webb Space Telescope has enabled another long-sought scientific breakthrough, this time for Solar System scientists studying the origins of the water that has made life on Earth possible. Using Webb’s NIRSpec (Near-Infrared Spectrograph) instrument, astronomers have confirmed gas – specifically water vapour –Continuar Leyendo

Using ESO’s Very Large Telescope (VLT), researchers have found for the first time the fingerprints left by the explosion of the first stars in the Universe. They detected three distant gas clouds whose chemical composition matches what we expect from the first stellar explosions. These findings bring us one stepContinuar Leyendo

For the first time, astronomers have observed, in the same image, the shadow of the black hole at the centre of the galaxy Messier 87 (M87) and the powerful jet expelled from it. The observations were done in 2018 with telescopes from the Global Millimetre VLBI Array (GMVA), the AtacamaContinuar Leyendo

Quakes could be the source of the mysteriously smooth terrain on the moons circling Jupiter and Saturn, according to a new study led by a University of Arizona graduate student. Many of the ice-encrusted moons orbiting the giant planets in the far reaches of our solar system are known toContinuar Leyendo

París, April 08, 2023.- The explosion of a star is a dramatic event, but the remains that the star leaves behind can be even more dramatic. A new mid-infrared image from NASA/ESA/CSA James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), createdContinuar Leyendo

Los candidatos a astronautaContinuar Leyendo

March 24 marks 6 months until the University of Arizona-led OSIRIS-REx mission is scheduled to return material from the dawn of the solar system to Earth for study. Tucson, March 30, 2023.- The University of Arizona’s OSIRIS-REx team is eagerly awaiting the arrival of pristine material from asteroid Bennu, marking theContinuar Leyendo

ESA’s Gaia mission has helped discover a new kind of black hole. The new family already has two members, and both are closer to Earth than any other black hole that we know of. A team of astronomers studied the orbits of stars tracked by Gaia and noticed that someContinuar Leyendo

The European Space Agency ESA’s Juice space mission is scheduled to start its journey to Jupiter on April 13, 2023. Once arrived, one of the goals of Juice is to search for traces of life on three of Jupiter’s icy moons. The University of Bern is contributing the NIM massContinuar Leyendo
