New Horizons has shown Pluto to be a diverse world, more so than many scientists had anticipated, with tall mountain ranges, vast glaciers, a blue-colored […]

Mystery Deepens: New Study Shows Comets Don't Explain Odd Dimming of Kepler's 'Weird Star'

The mystery surrounding KIC 8462852 may not involve comets after all, but it is still an enigma for astronomers. Image Credit: NASA/JPL-Caltech

As has been reported previously on AmericaSpace, and elsewhere, there is something weird going on around a star which is a little over 1,400 light-years away. Astronomers are still baffled as to […]

Webb Telescope Component Completes Critical Tests as Mirror Installations Continue

Less than three years from its launch, the James Webb Space Telescope (JWST), an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA), continues to take shape. As 2015 rolled into 2016, engineers working on the JWST have been busy testing one of its essential science components. On […]
