Post navigation NASA is conducting tests to make sure their new spacecraft, Artemis II, is safe to return to Earth successfully. This includes simulations of the capsule in a variety of potential scenarios as it re-enters Earth’s atmosphere. Ultimately, these extensive tests will ensure the crew and the capsule arrive back home safely. Astronomers have recently identified a black hole that is emitting strange radio signals which no current theory of black hole behavior can explain. This small black hole is the size of a star, but possesses the same strong gravitational pull as a supermassive black hole. Scientists are hopeful that this phenomenon could help to deepen our understanding of black hole behavior.
