NASA’s Jet Propulsion Laboratory, commercial companies, and academic institutions together are developing the first space-based quantum sensors for gravitational measurement. Two groups of very cold rubidium atoms will be used as weights for the Quantum Gravity Gradiometer Pathfinder (QGGPf) instrument, ensuring accurate measurements over long periods. Measuring gravity with a volume of 0.3 cubic yards … Read more
A new study published on March 26 in the Nature journal revealed that the magma ocean formation near Earth’s core started around 4.4 billion years ago.
