NASA to investigate climate impacts of Arctic sea ice loss
A new NASA field campaign will begin flights over the Arctic this summer to study the effect of sea ice retreat on Arctic climate. The Arctic Radiation IceBridge Sea and Ice Experiment (ARISE) will conduct ...
Researchers find young galaxies not behaving as expected
(Phys.org) —New Herschel Space Observatory findings have given scientists a remarkable insight into the internal dynamics of two young galaxies. Surprisingly, they have shown that just a few billion years ...
Researchers find evidence of speedy core formation in solar system planetesimals
Galaxies fed by funnels of fuel
(Phys.org) —Computer simulations of galaxies growing over billions of years have revealed a likely scenario for how they feed: a cosmic version of swirly straws.
Building blocks of life found around young star
(Phys.org)—A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has spotted sugar molecules in the gas surrounding a young Sun-like star. This is the first time sugar been ...
New theory points to 'zombie vortices' as key step in star formation
(Phys.org) —A new theory by fluid dynamics experts at the University of California, Berkeley, shows how "zombie vortices" help lead to the birth of a new star.
Explosion of galaxy formation lit up early universe
(Phys.org)—New data from the South Pole Telescope indicates that the birth of the first massive galaxies that lit up the early universe was an explosive event, happening faster and ending sooner than suspected.
There is more gas in the Galaxy than is dreamt of by astronomers
(Phys.org) —A survey from Herschel has revealed that the reservoir of molecular gas in the Milky Way is hugely underestimated - almost by one third - when it is traced with traditional methods. Monitoring ...
Scientists create faster, more sensitive photodetector by tricking graphene
(Phys.org) -- Researchers at the Center for Nanophysics and Advanced Materials of the University of Maryland have developed a new type of hot electron bolometer a sensitive detector of infrared light, that ...
Tiny ring laser accurately detects and counts nanoparticles
(PhysOrg.com) -- A microlaser no bigger than a pinprick can accurately detect and count individual viruses, the particles that jumpstart cloud formation or those that contaminate the air we breathe.
Herschel Space Observatory discovers source of cosmic dust in a stellar explosion
(PhysOrg.com) -- ESA's Herschel Space Observatory is helping unravel the mystery of where cosmic dust comes from. Thanks to the resolution and sensitivity of Herschel, astronomers have been able to detect ...
Cloud mystery solved: Global temperatures to rise at least 4C by 2100
Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature. Scientists found global climat ...
Research maps where stars are born
(Phys.org) —A University of Arizona-led group of astronomers has completed the largest-ever survey of dense gas clouds in the Milky Way – pockets shrouded in gas and dust where new stars are being born.
Solar activity playing a minimal role in global warming, research suggests
Changes in solar activity have contributed no more than 10 per cent to global warming in the twentieth century, a new study has found.
