NASA satellites discovered a sunspot on our Sun s surface as our host star sprayed plasma on the surface. This could result in a solar flare with a speed of 1.8 million kilometers per hour.
Since sunspots have high magnetic fields, these plasmas are usually hotter.

Coronal rain, like that shown in this movie from NASA s SDO in 2012, is sometimes observed after solar eruptions, when the intense heating associated with a solar flare abruptly cuts off after the eruption and the remaining plasma cools and falls back to the solar surface.

A short-lived resurgence in the emission of ozone-depleting pollutants in eastern China will not significantly delay the recovery of Earth’s protective “sunscreen” layer, according to new research published Feb. 10 in Nature.
Stratospheric ozone, also known as Earth’s ozone layer, helps shield us from the Sun’s harmful Ultraviolet (UV) rays. Compounds like CFC-11 (Trichlorofluoromethane, also known as Freon-11), a chemical once considered safe and widely used as a refrigerant and in the production of insulation for buildings, rise to the stratosphere after emission on Earth’s surface. Once in the atmosphere, CFCs are broken down by the UV light and result in the destruction of ozone molecules,
