Formation mechanism of solar double-decker filament

Researchers led by Zhang Yan and Yan Xiaoli from the Yunnan Observatories (YNAO) of the Chinese Academy of Sciences have revealed the formation mechanism of solar double-decker filament.

Laser creates a miniature magnetosphere

Magnetic reconnections in laser-produced plasmas have been studied to understand microscopic electron dynamics, which is applicable to space and astrophysical phenomena. Osaka University researchers, in collaboration with ...

Solar wind a major driver of atmospheric sodium at Mercury

No object in the solar system experiences the sun's solar wind more powerfully than Mercury. The planet's magnetic field deflects the sun's stream of electrically charged particles at a distance of only 1,000 kilometers from ...

New theory explains mystery behind fast magnetic reconnection

When magnetic field lines of opposite directions merge, they create explosions that can release massive amounts of energy. On the sun, the merging of opposing field lines causes solar flares and coronal mass ejections, giant ...

Modeling Earth's magnetosphere in the laboratory

A magnetosphere forms around any magnetized object, such as a planet, that is immersed within a stream of ionized gas, called plasma. Because Earth possesses an intrinsic magnetic field, the planet is surrounded by a large ...

Scientists reveal source of supersonic downflows into sunspots

Solar transition region supersonic downflows (SDs) are downward falling mass flux toward the sunspots. This phenomenon commonly exists above most sunspots. In IRIS spectra, SDs are often observed as strongly redshifted secondary ...
