Sounding rocket CLASP2 elucidates solar magnetic field

Cooperative operations between a solar observation satellite and a sounding-rocket telescope have measured the magnetic field strength in the photosphere and chromosphere above an active solar plage region. This is the first ...

First humans in Tasmania must have seen spectacular auroras

Drilling a 270,000-year old core from a Tasmanian lake has provided the first Australian record of a major global event where the Earth's magnetic field 'switched'—and the opportunity to establish a precedent for developing ...

NASA explores solar wind with new view of small sun structures

Scientists have combined NASA data and cutting-edge image processing to gain new insight into the solar structures that create the Sun's flow of high-speed solar wind, detailed in new research published today in The Astrophysical ...

The U.S. Postal Service to issue NASA sun science forever stamps

NASA's images of the sun's dynamic and dazzling beauty have captivated the attention of millions. In 2021, the US Postal Service is showcasing the sun's many faces with a series of sun Science forever stamps that show images ...

Energy from solar wind favors the north

Using information from ESA's Swarm satellite constellation, scientists have made a discovery about how energy generated by electrically-charged particles in the solar wind flows into Earth's atmosphere—surprisingly, more ...

Coronal holes during the solar maximum

Sunspots were first seen by Galileo, and in the eighteenth century Rudolf Wolf concluded from his study of previous observations that there was a roughly eleven-year solar cycle of activity. In 1919 the astronomer George ...

NASA extends exploration for two planetary science missions

As NASA prepares to send astronauts back to the Moon and on to Mars, the agency's quest to seek answers about our solar system and beyond continues to inform those efforts and generate new discoveries. The agency has extended ...
