#4 – Massive Solar Flares
Every so often, the sun gives off solar flares. These are basically waves of particles that are supercharged with energy, move at great speed, and head straight for Earth. So far, we’ve been safe due to protection from our planet’s magnetic field and resilient atmosphere. However, astronomers have discovered that other stars are capable of giving off “super flares” which are far, far more powerful than the flares we are used to. If the Sun ever charges up and hits us with one of those, Earth would be scorched and our ozone layer burned away entirely.
