Huge reservoir of melting carbon discovered under Western US

Scientists using the world's largest array of seismic sensors found a huge area of melting carbon covering 1.8 million km2 (684 000 mi2), 350 km (217.5 miles) beneath the Western US. The discovery challenges accepted the understanding of how much carbon the...

Earth's water comes from within

A new study published recently in Earth and Planetary Science Letters suggests that much of our planet's water comes from within, rather than arriving from space through collisions with ice-rich comets. The study also suggests that chemical reactions responsible...

Scientist found lost continent under Mauritius

Scientists found 'lost continent' under Mauritius

An international team of scientists has confirmed the existence of a 'lost continent' under the Indian Ocean island of Mauritius that was left-over by the break-up of the supercontinent, Gondwana, which started about 200 million years ago. The piece of...

gamma rays from far side solar flares

Fermi sees gamma rays from Sun's far side

Fermi Gamma-ray Space Telescope has observed high-energy light from solar eruptions located on the Sun's far side, which should block direct light from these events. This apparent paradox is providing solar scientists with a unique tool for exploring how charged...

rapid gas flares detected for the first time

Incredibly rapid gas flares detected from SS Cyg

Oxford University scientists have detected incredibly rapid gas flares from a dwarf binary star system. This is the first sighting of such activity and it suggests that our current understanding of star habits and their capabilities is incomplete. The rapid flares,...

EEGGL - New space weather model available to the public

A team at the University of Michigan has developed a new space weather model called EEGGL, short for the Eruptive Event Generator (Gibson and Low), in an effort to help researchers better understand how the Sun will affect near-Earth space, and potentially improve...

Study links Earth's orbital variations, sea ice and ice ages

Earth is currently in what climatologists call an interglacial period, a warm pulse between long, cold ice ages when glaciers dominate our planet's higher latitudes. For the past million years, these glacial-interglacial cycles have repeated roughly on a...

Study examines 1 000 years of volcanic ash fallout over Europe

A new study, led by researchers from the University of Leeds, suggests that flight-disrupting ash clouds are more common over northern Europe than previously thought and puts the average gap between them at about 44 years. The study also reveals that these types of...

Shockingly powerful lightning on Earth

A new scientific paper suggests that lightning on Earth may be vastly more powerful than conventional science has ever suggested. Investigators sought to answer how much energy is in a terrestrial bolt of lightning through the study of fulgurites, which are hollow...

Campi Flegrei showing signs of reawakening, Italy

A new study suggests that Campi Flegrei, a volcano in the metropolitan area of Naples, one of the most densely inhabited areas in the world, may be near a critical pressure point which would reawaken it from its, almost 500 years long, sleep. In the course of a new...
