Detecting neutrinos, physicists look into the heart of the sun

Using one of the most sensitive neutrino detectors on the planet, physicists have directly detected neutrinos created by the 'keystone' proton-proton fusion process going on at the sun's core for the first time.

ESA reveals candidates for new space science missions

Earth’s protective barrier – the magnetosphere – shields it from some of the effects of the supersonic solar wind. Studying the interaction between this wind and the magnetosphere is important for our understanding of space weather.

Solar Orbiter launch moved to 2018

The launch of Solar Orbiter, an ESA mission to explore the Sun in unprecedented detail, is now planned to take place in October 2018. The launch was previously targeted for July 2017.

Solar Scientists Say Cycle 24 is the Weakest in More than a Century

Four leading solar scientists on December 11 told journalists attending the American Geophysical Union (AGU) fall conference in San Francisco that current solar Cycle 24 has demonstrated extremely low sunspot activity and appears to be the weakest cycle of the past 10 cycles — more than 100 years. This already has resulted in milder “space weather” and less-intense geomagnetic storms and “energetic particle events,” such as coronal mass ejections (CMEs), NASA scientist Nat Gopalswamy said.

Matter-antimatter asymmetry: Using the sun to illuminate a basic mystery of matter

Antimatter has been detected in solar flares via microwave and magnetic-field data, according to researchers. The finding sheds light on the puzzling strong asymmetry between matter and antimatter by gathering data on a very large scale using the Sun as a laboratory.

As the Sun Awakens, NASA Keeps a Wary Eye on Space Weather

Earth and space are about to come into contact in a way that's new to human history. To make preparations, authorities in Washington DC are holding a meeting: The Space Weather Enterprise Forum at the National Press Club on June 8th.

Sunspot detail revealed by supercomputers

A comprehensive computer model of sunspots unveiled by scientists at the National Center for Atmospheric Research (NCAR) and the Max Planck Institute for Solar System Research (MPS) in Germany will advance research into the inner workings of our Sun and its impact on the Earth.

GNSS and Space Weather

When the solar winds come around, you’d better hang onto your GNSS receiver, not your hat. That’s because satellite signals propagating through the Earth’s atmosphere can be profoundly affected when the Sun acts up, as it does periodically in 11-year cycles — the upward trajectory of which is just beginning. But a U.S. federal agency now offers help for users to minimize the effects on their GNSS-dependent activities.
