On the generation of solar spicules and Alfvenic waves

Combining computer observations and simulations, a new model shows that the presence of neutrals in the gas facilitates the magnetic fields to penetrate through the surface of the Sun producing the spicules. In this study, ...

Scientists uncover origins of the Sun's swirling spicules

At any given moment, as many as 10 million wild jets of solar material burst from the sun's surface. They erupt as fast as 60 miles per second, and can reach lengths of 6,000 miles before collapsing. These are spicules, and ...

Satellite's last days improve orbital decay predictions

Scientists are learning more about how the upper atmosphere and ionosphere affect space satellites as well as communications and navigation here on Earth, thanks to new data from a U.S. Air Force satellite that recently completed ...

NASA plans twin sounding rocket launches over Norway this winter

This winter, two sounding rockets will launch through the aurora borealis over Norway to study how particles move in a region near the North Pole where Earth's magnetic field is directly connected to the solar wind. After ...

ICON cleared for next development phase

NASA has officially confirmed the Ionospheric Connection Explorer, or ICON, mission, clearing it to move forward into the development phase. ICON will explore a swath of Earth's atmosphere where weather close to the ground ...

Spinning atoms in light crystals

(Phys.org) —After more than 40 years of intense research, experimental physicists still seek to explore the rich behaviour of electrons confined to a two-dimensional crystalline structure exposed to large magnetic fields. ...

Fermilab sends first neutrino beam to NOvA experiment

DOE's Fermilab has switched on its newly upgraded neutrino beam, soon to be the most intense in the world. The laboratory spent the past 15 months upgrading its accelerator complex in preparation for the NOvA experiment, ...
