Researchers at MIT, the University of Colorado and elsewhere have found that very low-frequency electromagnetic waves in the Earth’s upper atmosphere form a shield, protecting the planet’s surface from the Van Allen belt’s high-energy radiation.
A team led by Dr. Sebastian Hoenig from the University of Southampton has developed a new way of measuring precise distances to galaxies tens of millions of light-years away, refining the distance to NGC 4151 and providing a way for accurately determining black hole masses.
Launched in 2007, Nasa’s Dawn spacecraft orbited and surveyed large asteroid Vesta between July 2011 and September 2012. This detailed map is the culmination of a two-and-a-half-year geological mapping campaign.
Scientists hope private backers will kick-start a mission to land a robotic probe on the South Pole of the moon within the next 10 years, drill deep into lunar bedrock and analyze primordial core samples to study the origins of the solar system.
Recent theories suggest that the production of Higgs particles in the inflationary phase of the early universe should have led to instability and collapse. Now a European team offers an explanation why this didn’t happen, answering fundamental questions about how we are all here.
