CORONAL HOLE – A region in the Sun’s corona with lower-than-average temperatures and density, often the source of high-speed solar wind.

SOLAR FLARE – A sudden, explosive release of energy from the Sun’s surface, often accompanied by bursts of radiation across the electromagnetic spectrum.

SUNSPOT CYCLE – The 11-year cycle of solar activity, including the number of sunspots, solar flares, and coronal mass ejections.

GEOMAGNETIC STORM – A disturbance in Earth’s magnetic field caused by interactions with solar wind or CMEs, leading to phenomena like auroras.

SPACE WEATHER – The environmental conditions in space, influenced by the Sun’s activity, that can affect satellite systems, power grids, and communications.

CORONAL MASS EJECTION (CME) – A massive burst of solar wind and magnetic fields rising above the solar corona, often associated with solar flares.

AURORA BOREALIS – The Northern Lights, a natural light display in the sky caused by charged particles from the solar wind interacting with Earth’s magnetosphere.

MAGNETOSPHERE – The region around a planet, including Earth, controlled by its magnetic field, which shields it from the solar wind.

SOLAR WIND – A continuous stream of charged particles, mainly protons and electrons, emitted from the Sun’s corona.
