Photo of the Day Our Sun frequently erupts in loops. Hot solar plasma jumps off the Sun's surface into prominences, with the most common type of prominence being a simple loop. The loop shape originates from the Sun's magnetic field, which is traced by spiraling electrons and protons. Many loops into the Sun's lower [...]

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA/Lori Losey The best way to solve a mystery is by gathering evidence and building a case. That’s exactly what NASA researchers are doing with a series of research flights aimed at advancing a sensor for supersonic parachutes. The clues they find could help [...]
