First there were the unusual bright spots on Ceres, which are still awaiting an explanation, and now as New […]

Astronomers Find First Evidence of Possible Volcanic Activity On a Super-Earth Exoplanet

Discovering new exoplanets has become rather routine in the last few years, but determining just what conditions exist on any of them is naturally more difficult, since […]

NASA Space Telescope Sees Possible X-Ray 'Screams' From Zombie Stars

It sounds like something from a bad sci-fi movie, but a NASA space telescope has detected what might be the X-ray “screams” from dead (zombie) stars. The Nuclear Spectroscopic Telescope […]

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.

With exoplanets now being discovered by […]

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 […]

Kepler Confirms Over 1,000 Exoplanets, Finds More Potentially Habitable Worlds

Even after problems threatened to end the Kepler space telescope’s mission for good last year, the planet-hunting observatory has continued to help astronomers discover thousands of exoplanets orbiting […]

Kepler Finds 'Super-Earth' Exoplanet in First Discovery of New Mission

The Kepler space telescope has found its first new exoplanet, a “super-Earth,” of its secondary mission phase. The discovery adds to a current tally of 996 confirmed exoplanets and 4,183 planetary candidates already found by the revolutionary planet-hunting telescope.

Airships are a unique form of transportation—giant, balloon-like, lighter-than-air vehicles which can stay aloft for extended periods of time. Their design makes them […]

TESS Exoplanet-Hunting Space Telescope Ready for Development

The search for exoplanets is about to enter an exciting new phase, as the Transiting Exoplanet Survey Satellite (TESS) mission has now been cleared for development by NASA. TESS will greatly expand the number of stars being observed for evidence of exoplanets […]

New Dust Map of Galaxy Casts Doubts on Gravitational Waves Discovery

All-sky map of interstellar dust from Planck. Blue areas have less dust and red areas have more. The patch of sky observed by BICEP2 is not in one of the less dusty regions. Northern hemisphere is on the left and southern is on the right. Image Credit: ESA

As sometimes happens, the celebrations may […]
