Apparently, PLANCK says that BICEP2 did not detect gravitational waves.  The signal was mostly intergalactic dust.   That is my reading of a Google translate translation of an official…

To put it briefly, the habitability of a planet depends on it's distance from its star, the composition of its atmosphere, and the type of star its orbiting.  If our own solar system is at all…

What exactly is cometary globule CG4?  That's still a bit of a mystery. Despite the name, it has nothing to do with comets. In 1976, several elongated comet-like objects were discovered in…

The first radar images of asteroid 2004 BL86, which made its closest approach today at 8:19 a.m. PST - a distance of only 745,000 miles (3.1 times the distance from Earth to the moon) - reveal that…

Astronomers have discovered a ring system eclipsing the very young Sun-like star J1407. And it is huge, much larger and heavier than the ring system of Saturn. The ring system, the first of its…

Ten years ago, on Jan. 14, 2005, some orange-y image, showing an alien scenery with lots of pebbles in the horizon, was at the center of ESA scientists’ attention. The snapshot of a distant world’…

By Anton Wallner, Australian National University Our understanding of heavy element production in supernovae, exploding stars way beyond our solar system, may need to change following some…

Two teams of astronomers have used computer models to look back nearly 13 billion years, when the Universe was less than 10 percent its present age, to determine how quasars - extremely luminous…

Jupiter's moons are giving us a show not seen since 2013: The orbital path of the moons is tilting edge-ion to the Earth and the sun, making it possible to watch the moons pass in front of each other…

Geologists have discovered hidden magnetic messages from the early solar system in meteorites measured using the PEEM-Beamline at the BESSY II synchrotron located in The Helmholtz-Zentrum Berlin für…
