UNH scientists provide new tools for predicting arrival and impact of solar storms

When the Sun hurls a billion tons of high-energy particles and magnetic fields into space at speeds of more than a million miles per hour and the “space weather” conditions are right, the resulting geomagnetic storm at Earth can wreak havoc on communication

MESSENGER and STEREO measurements open new window into high-energy processes on the Sun

Understanding the sun from afar isn't easy. How do you figure out what powers solar flares – the intense bursts of radiation coming from the release of magnetic energy associated with sunspots – when you must rely on observing only the light and particle

Unique cosmic coincidence - comets Encke and ISON to fly by Mercury

Comet Encke will fly by Mercury within 0.025 AU (3.74 million km) on November 18, 2013 and only a day later, Comet ISON will pass it at 0.24 AU. This is a unique cosmic coincidence and NASA's MESSENGER spacecraft, which is orbiting the planet,
