Here’s an excellent reason to keep looking up, thanks to the American Meteor Society: not just great but greater balls of fire overhead in recent months.
While it’s nothing to worry about, according to AMS — neither an alien invasion nor any measurable increase in the risk of impact — there does seem to be a statistical spike now underway in “large fireball” reports coming in from people all around the planet.
“AMS logged an unprecedented concentration of major fireballs” in mid-March, the agency reported at the end of the month.
What is a fireball? It’s a meteor — a chunk of space debris — that hits our atmosphere at astronomical speed and starts to burn due to friction and compression. Many meteors become tiny white “shooting stars” that disappear from view almost immediately. But meteors that seem to have some bulk, and burn exceptionally brightly, are called fireballs.
Fireballs can be really spectacular, glowing different colors (red, orange, yellow, even blue) and even putting off glowing “trains” of ionized particles, or trails of smoke.
