Today was a big day for physicists and space science, with the announcement of the first confirmed detection of gravitational waves, 100 years after they had been predicted by Albert Einstein as a major aspect of his general […]

Is 'Planet 9' Really a Second Massive Kuiper Belt?

The Kupier Belt is a massive collection of dwarf planet and asteroid-sized worlds orbiting far past Neptune. Is the hypothetical Planet 9 really a second such belt? Image Credit: T. Pyle (SSC)/JPL-Caltech/NASA

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 […]

Record-Shattering, Ultra-Luminous Hypernova Explosion Stuns Astronomers, Poses New Cosmic Mystery

New Study Suggests Earth May Be Surrounded by Long Hair-Like Filaments of Dark Matter

A new theoretical study has shown that Earth may be surrounded by long and very dense hair-like filaments of dark matter, which could potentially be directly observed by dedicated space-based dark matter detectors. Image Credit: NASA/JPL-Caltech

The James Webb Space Telescope (JWST) just took a big step toward reality with the successful installation of the first of its many flight mirrors. This is […]

Spitzer Data Suggests Kepler's Strange 'Alien' Star is Surrounded by Comets, not Alien Megastructures

An artist's illustration of cometary fragments passing in front of a star. A new study based on data gathered by NASA's Spitzer Space Telescope suggests that the anomalous dips in brightness that have been observed around the star KIC 8462852 are caused by the fragmentation of similar cometary fragments.
