AST SpaceMobile of Midland, Texas, builder of the BlueBird 7 satellite, said in a statement the cellular relay station’s on-board propulsion…
In a major advance, researchers at the Indian Institute of Science (IISc) have devised a method to grow high-quality 2D magnetic materials (2D-MMs) over centimeter-scale wafers. Earlier approaches in the field were limited to growing micrometer-sized flakes. This advance paves the way for their integration into next-generation electronics and spintronics materials used in hard drives…

The Perseus Cluster is a massive galaxy cluster located in the constellation Perseus. It is one of the largest structures in the observable universe, comprising more than a thousand galaxies—equivalent to roughly a thousand trillion times the mass of the sun. Hot gases within the cluster, known as the intracluster medium (ICM), emit powerful X-rays…
