Planck: Gravitational waves remain elusive

Despite earlier reports of a possible detection, a joint analysis of data from ESA's Planck satellite and the ground-based BICEP2 and Keck Array experiments has found no conclusive evidence of primordial gravitational waves.

Dust kicked up in Asia strengthens Indian monsoon within a week

A new analysis of satellite data reveals a link between dust in North Africa and West Asia and stronger monsoons in India. The study shows that dust in the air absorbs sunlight west of India, warming the air and strengthening ...

The Energy Sources of Ultraluminous Galaxies

(PhysOrg.com) -- Ultraluminous infrared galaxies ((ULIRGs) are galaxies whose luminosity exceeds that of a trillion suns; for comparison, the Milky Way galaxy has a typical (and much more modest) luminosity of only about ...

Cosmic 'dust' from supernovae hints at how stars are born

New research detected strong polarization from a young supernova remnant. It provided independent and solid evidence that the cosmic dust in the early universe was formed in supernovae. While it's true that supernovae eject ...

Amazon fires 'quicken Andean glacier melt'

Fires in the Amazon rainforest are likely to increase the rate of melting of Andean glaciers, potentially disrupting water supply for tens of millions of people, scientists said on Thursday.

Rosetta unravels formation of sunrise jets

The atmosphere of Rosetta's comet 67P/Churyumov-Gerasimenko is far from homogeneous. In addition to sudden outbursts of gas and dust, daily recurring phenomena at sunrise can be observed. In these, evaporating gas and entrained ...

Snow and sand erosion explained

Scientists at EPFL and SLF describe with precision how snow and sand surfaces erode when exposed to wind. Their description can contribute to better predictions of dust emissions from deserts and snow transport in Antarctica, ...

Tune your radio: Galaxies sing when forming stars

A team led from the Instituto de Astrofísica de Canarias (IAC) has found the most precise way ever to measure the rate at which stars form in galaxies using their radio emission at 1-10 Gigahertz frequency range.
