The impacts of solar flare radiation on Mars are relevant to exploration and the search for life on the planet. Models of its atmosphere indicate that the most energetic solar flares previously recorded may have provided acute doses of radiation that would have been almost harmful or lethal to mammals and other higher organisms on Mars's surface.
Each class of solar flare is also graded on number scale, from 1 to 9, to determine its exact impact. There's an exception with X-class flares, however, which can go higher than 9.
Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
On 8 May 2024, a solar active region which had been assigned the NOAA region number 13664 (AR3664) produced an X1.0-class and multiple M-class solar flares and launched several coronal mass ejections (CMEs) toward Earth. [6] On 9 May, the active region produced an X2.25- and X1.12-class flare each associated with a full-halo CME.
A powerful solar flare has been hurled out of the Sun, and could cause disruption on Earth. The flare comes amid increasing solar activity that has brought a run of intense space weather in recent ...
Our life-giving death star is experiencing its "solar maximum," which sounds like the name of a Christian rock band and is defined as the peak activity period within the sun's 11-year solar cycle.

The Sun has unleashed a powerful solar flare, Nasa has said. The flare, designated X2.3, belongs to the most intense X class of flares. It was spotted by Nasa’s Solar Dynamics Observatory, which ...
