Astronomers spot a rare planet-stripping eruption on a nearby star

SMRTR summary

The eruption from a red dwarf star 130 light-years away traveled at extraordinary speeds and was powerful enough to strip atmospheres from nearby planets, potentially affecting habitability around the most common star types hosting exoplanets.
