New research looks at how ‘cosmic web’ of filaments alters star formation in galaxies

Astronomer Gregory Rudnick sees the universe crisscrossed by something like an interstellar superhighway system. Filaments — the strands of aggregated matter that stretch millions of light years across the universe to connect galaxy clusters — are the...

atmospheric rivers study

Study estimates global reach of atmospheric rivers

A recent study by NASA and several partners has estimated, for the first time, the global impact of atmospheric rivers on floods and droughts, as well as the number of people affected by these atmospheric phenomena. Atmospheric rivers are relatively long, narrow,...

Saturn's radiation belts: A stranger to the solar wind

The high energy proton population in the environment of Saturn develops independently of the solar wind - and thus in a considerably different way from the one on Earth. The radiation belts of Earth and Saturn differ more strongly than previously assumed. In these...

'Monster' planet discovery challenges formation theory

A giant planet - the existence of which was previously thought extremely unlikely - has been discovered by an international collaboration of astronomers, with the University of Warwick taking a leading role. New research, led by Dr. Daniel Bayliss and Professor...

The Amazon makes its own wet season

Scientists have known for some time that transpiration—the process by which plants and trees release moisture to the atmosphere—contributes much of the water that falls back down on the Amazon rainforest in its "wet season." But that moisture...

Oldest recorded solar eclipse helps date the Egyptian pharaohs

Researchers have pinpointed the date of what could be the oldest solar eclipse yet recorded. The event, which occurred on October 30, 1207 BC could have consequences for the chronology of the ancient world. Using a combination of the biblical text and an ancient...

Drilling into magma reservoirs to improve volcano forecasts

The roots of volcanoes remain enigmatic, largely because geophysical and petrological models remain rudimentary. Scientific drilling and exploration can help. When it comes to forecasting eruptions, volcano observatories rely mostly on real-time signals from...

Spitzer reveals ancient galaxies' frenzied starmaking

A deep look back to the early universe by NASA's Spitzer Space Telescope has revealed a surprisingly rowdy bunch of galaxies. Within a large galaxy sample, Spitzer witnessed around 15% of galaxies undergoing bouts of extreme starmaking, called starbursts. The...

Surprisingly erratic X-ray auroras discovered at Jupiter

ESA and NASA space telescopes have revealed that, unlike Earth’s polar lights, the intense auroras seen at Jupiter’s poles unexpectedly behave independently of one another. Auroras have been seen in many places, from planets and moons to stars, brown...

How glaciers disappeared from Scotland at the end of the last Ice Age

Research led by a Stirling academic, Dr. Tom Bradwell, has revealed how glaciers disappeared from Scotland at the end of the last Ice Age. Bradwell led a research team in taking samples offshore around the north-west of Scotland, and Shetland. The activity was part...

Scientists detect comets outside our solar system

Scientists from MIT and other institutions, working closely with amateur astronomers, have spotted the dusty tails of six exocomets — comets outside our solar system — orbiting a faint star 800 light years from Earth. These cosmic balls of ice and dust,...

"Teleconnections" can enhance weather events caused by local conditions and create extreme weather events

A recent article in Reviews of Geophysics explored how regional climate and weather is interconnected across space and time. Weather patterns are generally described in regional terms but they do not occur in isolation because they are part of the global atmospheric...

Jets of ionospheric cold plasma discovered at the magnetopause

The Sun and Earth both produce powerful magnetic fields, and their intersection develops a complex system of physics that determines the space weather experienced by our planet. The solar wind - a constant stream of charged particles (plasma) emitted from the Sun -...

Yellowstone spawned twin super-eruptions that caused volcanic winters

A new geological record of the Yellowstone supervolcano's last catastrophic eruption is rewriting the story of what happened 630 000 years ago and how it affected Earth's climate. This eruption formed the vast Yellowstone caldera observed today, the second...

Anza Gap: Earthquake risk elevated with detection of spontaneous tectonic tremor

Scientists at the University of California, Riverside have detected spontaneous tectonic tremor - a signature of slow earthquakes deep below the earth’s surface - in the Anza Gap region of the San Jacinto Fault. Tectonic tremors are believed to increase the...

Japanese earthquake zone strongly influenced by the effects of friction

Kyushu University-led researchers identified strong influence of pre-existing fault and plate structure on earthquake location and behavior in the Nankai Trough offshore of Japan. The islands of the Japanese archipelago are affected both by frequent, low-magnitude...

Study links Raton Basin earthquakes to oil and gas fluid injections, again

A rash of earthquakes in southern Colorado and northern New Mexico recorded between 2008 and 2010 was likely due to fluids pumped deep underground during oil and gas wastewater disposal, says a new University of Colorado Boulder study. The study, which took place in...
