Heavy elements produced in neutron star collisions can 'surf' on the shock waves of other supernovae through our galaxy all the way to Earth. It is the conclusion of a sophisticated computer model of the journey of elements through space, developed by scientists from the University of Hertfordshire, UK, and the Konkoly-CSFK Observatory, Hungary. stellar explosions Many of the elements around us are produced in stellar explosions called supernovae or in violent collisions of extremely dense objects called neutron stars. One of the questions that intrigued scientists was how these heavy elements got to Earth and, in particular, how elements…

A new form of ice based on water and sodium chloride (table salt), created in the laboratory at low temperatures and high pressure, could be what exists in the red streaks that cross the surface of Europa, one of Jupiter's moons . A study published today by Pnas coordinated by the University of Washington describes this new type of ice that the team estimates is what could form on the surface and bottom of the deep oceans of some icy moons. Europa's surface is streaked with red streaks that scientists suspect are a frozen mixture of water and saltsbut its…

Every step in the history of humanity has been associated with a material key: without going any further, stone, bronze and silicon marked a before and after in the evolution of our species. “Now is the age of two-dimensional materials like graphene", Explain Carolina Aguilar, CEO and Co-Founder of INBRAIN Neuroelectronicsthe 'start-up' winner of the Empresa + Innovadora award granted by EL PERIÓDICO. The characteristics of graphene, the thinnest material known to man –with one atom thick, it is 200 times stronger than aluminum and is flexible, biocompatible, conductive–, make it irresistible for the development of nanotechnology. Some possibilities that…

The moon, the Earth's natural satellite, is a star that orbits around it and reflects sunlight. It has different phases, which influence on the tides and in the natural cycles of people, marked by their four most important phases: new moon, first quarter, full moon and waning quarter, which correspond to the precise instants in which the Earth-Moon and Earth-Sun directions form an angle of 0°, 90°, 180° and 270° respectively. A full moon occurs When the earth is between the sun and the moonso that it reflects sunlight with all its visible face, reaching its maximum illumination. Before arriving…
