First we discovered that a platypus would look great at a rave, and now wombats, plebeians, and other marsupials can join the black light party – as scientists unexpectedly discovered that they all glow nicely in green, blue, and pink
The sun is constantly releasing huge explosions of plasma into deep space. In this case, the particles emitted by the solar flare were directed directly at Earth, which led to technological problems on our planet. As a result, when the
NASA astronaut, Victor Glover, shared his first video from space as he and three other astronauts flew over Earth while traveling to the International Space Station. Glover is part of the Crew-1 mission launched aboard SpaceX’s Crew Dragon capsule, nicknamed
A study has concluded that the key to how vertebrates first appeared outside the ocean and began to invade Earth about 390 million years ago may lie in the arm bone. Experts from the United States and the United Kingdom
The first enhanced portion of the Space Launch System (SLS) was stacked on top of the portable launch pad at NASA’s Kennedy Space Center in Florida earlier this week in preparation for its maiden flight. NASA said Tuesday. A total
