The origin of spin in spiral and elliptical galaxies has posed a long-standing puzzle for astronomers. One idea, known as tidal torque theory, proposes that galaxies' spins are an imprinted record of the early universe, imparted ...
Researchers at The University of Alabama in Huntsville (UAH), part of The University of Alabama System, are developing plasma-based technology to help astronauts stay healthier during missions to the moon and Mars by sanitizing ...
