Researchers at the University of Illinois Urbana-Champaign watched fragments of two meteors as they ramped up the heat from room temperature to the temperature it reaches as it enters Earth’s atmosphere and made a significant discovery. The vaporized iron sulfide leaves behind voids, making the material more porous. This informationContinuar Leyendo

Dark energy, the mysterious force that causes the universe to accelerate, may have been responsible for unexpected results from the XENON1T experiment, deep below Italy’s Apennine Mountains. Cambrigde, September 16, 2021. – A new study, led by researchers at the University of Cambridge and reported in the journal Physical ReviewContinuar Leyendo

El homólogo terráqueo del vehículo robotizado de la ESA Rosalind Franklin ha logrado perforar y extraer muestras del suelo hasta una profundidad de 1,7 m, un valor mucho mayor del alcanzado hasta la fecha por ningún otro robot sobre la superficie de Marte. París, September 16, 2021.- Esta exitosa recogidaContinuar Leyendo

Transporting a single brick to Mars can cost more than a million British pounds — making the future construction of a Martian colony seem prohibitively expensive. Scientists at The University of Manchester have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrialContinuar Leyendo

As their name suggests, ultradiffuse galaxies, or UDGs, are dwarf galaxies whose stars are spread out over a vast region, resulting in extremely low surface brightness, making them very difficult to detect. Several questions about UDGs remain unanswered: How did these dwarfs end up so extended? Are their dark matterContinuar Leyendo

Encontrar y recoger las mejores muestras lunares será uno de los principales objetivos de los próximos astronautas que viajen a la Luna. Hoy despega la campaña formativa Pangaea de la Agencia Espacial Europea (ESA), destinada a dotar a los astronautas de una visión geológica sobre la Luna, que constituye elContinuar Leyendo

ESA and the United Nations Office for Outer Space Affairs are opening the second round of their HyperGES fellowship, part of the Access to Space For All Initiative, offering student teams around the globe the chance to perform hypergravity experiments using the Large Diameter Centrifuge at ESA’s ESTEC technical centreContinuar Leyendo

ESA safeguards Europe’s guaranteed access to space through its Future Launchers Preparatory Programme, FLPP. París, August 25, 2021.- FLPP oversees system studies and research activities to foster new and disruptive technologies which have the potential to reduce cost, improve performance, improve reliability, or on their ability to fulfil the specificContinuar Leyendo

Tiny iron nanoparticles unlike any found naturally on Earth are nearly everywhere on the Moon — and scientists are trying to understand why. A new study led by Northern Arizona University doctoral candidate Christian J. Tai Udovicic, in collaboration with associate professor Christopher Edwards, both of NAU’s Department of AstronomyContinuar Leyendo
