Jupiter Might Be Responsible for Our Unusual Solar System, Study Suggests

A montage of Jupiter and its volcanic moon Io, as seen by NASA’s New Horizons spacecraft on its way to Pluto. The results of a new study indicate that the massive gas giant fundamentally altered the evolution of the early Solar System, by destroying any “Super-Earth”-type planets that may have formed, while opening the […]

SPACE STATION WEEKLY UPDATE March 16 – March 22, 2015 — Over the last two weeks, the International Space Station (ISS) saw the end of one expedition and the beginning of another when […]

Scientists Create Color-Based Catalog of Earthly Life Forms to Help Search for Alien Biology

A hypothetical rendering of colorful plant life on a habitable exoplanet. Although most such alien life, if it exists, found with this technique may be microscopic, it illustrates how analysis of color could help scientists learn more about the physical nature of alien biology.

Under the Light of a Quadruple Sun: Astronomers Discover Additional Stellar Companions in Nearby Exoplanetary Systems

Artist’s conception of the quadruple star system 30 Arietis. The primary star, called 30 Arietis B, has a companion (the small “red dwarf” star shown at upper left). This pair of stars is itself locked in a long-distance orbit with another pair of stars (upper right), known as 30 Arietis A. A team of […]
