Researchers from North Carolina State University have discovered a technique for controlling light with electric fields. “Our method is similar to the technique used to provide the computing capabilities of computers,” says Linyou Cao, an assistant…
The emerging discipline of space meteorology aims to reliably predict solar flares so that we may better guard against their effects. Using 3D numerical models1, an international team headed by Etienne Pariat, a researcher at LESIA (Observatoire de Paris / CNRS /…
Very low frequency, or VLF, radio communications have been found to interact with particles in space, affecting how and where they move. At times, these interactions can create a barrier around Earth against natural high energy particle radiation in space. VLF…
If you could travel back in time 41 000 years to the last ice age, your compass would point south instead of north. That’s because for a period of a few hundred years, the Earth’s magnetic field was reversed. Magnetic reversals have happened repeatedly…
According to new research by UCL and the Vesuvius Observatory in Naples, the Campi Flegrei volcano in southern Italy may be closer to an eruption than previously thought. An eruption today would affect the 360 000 people living across the caldera and Naples'…
Data provided by the students of Earth to Sky Calculus and Dr. Tony Phillips of SpaceWeather.com show cosmic ray levels are intensifying, as the Solar Minimum approaches, with an approximately 13% increase since March 2015. This article provides a brief overview of…
An international team of scientists has developed a model that simulates the evolution of Stealth CMEs, solar storms that puzzled scientists for their lack of typical warning signs as they seem to come from nowhere. Such computer models can help researchers better…
New scientific reports suggest that ancient stone carvings confirm that a great comet struck the Earth over ten thousand years ago. Researchers at the University of Edinburgh in Scotland have studied the perplexing symbols carved on stone pillars at Gobekli Tepe in…
Scientists have discovered a vast wave of hot gas in the nearby Perseus galaxy cluster, spanning some 200 000 light-years. This is twice the size of our own Milky Way galaxy. The discovery was made combining data from NASA's Chandra X-ray Observatory with radio…
Genomic research associated with the Sima de los Huesos archaeological site and morphological analysis of hominin fossils from across Europe have together invalidated the possibility that Homo heidelbergensis is ancestral to Modern Humans. What happens when…
