We have it relatively easy on the Earth. Our Sun is relatively calm. The space weather environment in the solar system is altogether placid. Things are nice. But new research has shown that we may be the exception rather than the rule, and that many exoplanets face much harsher conditions than we do.

It Turns out, We Have a Very Well-Behaved Star

Our Sun is a Population II star about 5 billion years old. It contains elements heavier than hydrogen and helium, including oxygen, carbon, neon, and iron, though only in tiny percentags. Image: NASA/Solar Dynamics Observatory.

Should we thank our well-behaved Sun for our comfy home on Earth?

Some stars behave poorly. They’re unruly and emit powerful stellar flares that can devastate life on any planets within range of those flares. New research into stellar flares on other stars makes our Sun seem downright quiescent.
