Some scientists have been proposing extreme tactics in the fight against rising global temperatures.
Among 79 stars with several similarities—size, temperature, iron content, gravity—our sun is unusual.
Billions of years from now, the sun will expand and engulf the Earth.
Solar storms can impact power grids, GPS, and radio transmissions, among other things.
