About 17 years ago, J. Martin Laming, an astrophysicist at the U.S. Naval Research Laboratory, theorized why the chemical composition of the Sun's tenuous outermost layer differs from that lower down. His theory has recently ...
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 ...
The Sun's extremely hot outer layer, the corona, has a very different chemical composition from the cooler inner layers, but the reason for this has puzzled scientists for decades.
Using Xinglong observatory's Ground-based Wide Angle Cameras (GWAC), astronomers from China and France have detected a new superflare of an ultracool star known as SDSS J013333.08+003223.7. The newly found event, designated ...
A phenomenon first detected in the solar wind may help solve a long-standing mystery about the sun: why the solar atmosphere is millions of degrees hotter than the surface.
New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also varies between different types ...
Sunspots are darker regions which often appear on the Sun's surface. They are caused by strong concentrations of magnetic field, and can be as big as the Earth, or even much bigger.
Type III radio bursts from the sun are signatures of energetic (∼1–100 keV) electrons, accelerated at the reconnection sites, propagating upward through the corona into the interplanetary medium along open magnetic field ...
The first direct measurements of the magnetic field in the chromosphere of the sun by a team including University of Warwick physicists has provided the first observational evidence that huge tornadoes in our sun's atmosphere ...
An international team of astronomers has created the most detailed map yet of the atmosphere of the red supergiant star Antares. The unprecedented sensitivity and resolution of both the Atacama Large Millimeter/submillimeter ...
