Three solar flares occurred over a 24-hour period this week. While we may not see them with a naked eye, they can affect Earth. Here's how.
The sun is entering a new phase and it's going to have serious repercussions for human life. Experts: Sun’s increasing solar flares could cause major problems Skip to main content
Solar flares are intense, localized bursts of electromagnetic radiation from the sun, releasing immense energy over short periods. These events impact Earth's upper atmosphere and can occasionally ...
A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.
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 ...
effects on biological damage related to differences between space radiation and x-rays; dependence of risk on dose-rates in space related to the biology of DNA repair, cell regulation and tissue responses; predicting solar particle events (SPEs) extrapolation from experimental data to humans and between human populations
A growing body of research is finding evidence of violent solar flares deposited in natural archives like tree rings and glacial ice.. Scientists have so far identified five extreme solar particle ...
Solar flares strongly influence space weather near the Earth. They can produce streams of highly energetic particles in the solar wind, known as a solar proton event. These particles can impact the Earth's magnetosphere in the form of a geomagnetic storm and present radiation hazards to spacecraft and astronauts. A solar flare
