WebA flare is defined as a sudden, rapid, and intense variation in brightness. A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. Radiation is emitted across virtually the entire electromagnetic spectrum, from radio waves at the long wavelength end, through optical emission to x-rays and gamma ... WebCoronal Mass Ejections (CMEs) are large expulsions of plasma and magnetic field from the Sun’s corona. They can eject billions of tons of coronal material and carry an embedded magnetic field (frozen in flux) that is stronger than the background solar wind interplanetary magnetic field (IMF) strength. CMEs travel outward from the Sun at ...

Web12 hours ago · The Sun’s menacing solar flares are many times the size of earth. Massive geomagnetic storms can wreak havoc on our planet when solar flares eject CMEs (coronal mass ejections). Scientists have now been able to successfully replicate these solar flares in a lab, from the size of many earths to a man-made one that can fit inside a tiffin box. WebWhat is a Solar Flare?
