In 2020, scientists reported the detection of hematite, an iron oxide mineral otherwise known as rust, distributed through the higher latitudes of the moon, particularly on the nearside. This came as a surprise, considering ...
A cluster of space weather satellites blasted off Wednesday morning to cast fresh eyes on solar storms that can produce stunning auroras but also scramble communications and threaten astronauts in flight.

The solar wind is a stream of charged particles—a plasma—ejected from the upper atmosphere of the sun. It consists mostly of electrons and protons with energies of about 1 keV. The stream of particles varies in temperature and speed with the passage of time. These particles are able to escape the sun's gravity, in part because of the high temperature of the corona, but also because of high kinetic energy that particles gain through a process that is not well-understood.
The solar wind creates the Heliosphere, a vast bubble in the interstellar medium surrounding the solar system. Other phenomena include geomagnetic storms that can knock out power grids on Earth, the aurorae such as the Northern Lights, and the plasma tails of comets that always point away from the sun.
