☄️ BREAKING NEWS! A 7-TON ASTEROID EXPLODED over Northeast Ohio just before 9am 3/17, ripping through the atmosphere at 40,000 mph before detonating with the force of 250 tons of TNT. 💥 NASA says the fireball first appeared 50 miles above Lake Erie near Lorain, blazing a bright streak across the sky before fragmenting 30 miles above Valley City, Ohio in Medina County. The shockwave was strong enough to send booms across the region and even shake houses several counties away. Even more incredible: pieces of this asteroid may now be scattered across Medina County as meteorites. 🪨☄️ 👀 Did YOU see the fireball or hear the explosion this morning? It was visible from Toronto to Chicago to Washington DC. Drop your town in the comments and tell us what you experienced! 📲 SHARE this post so friends across Ohio, Pennsylvania, Michigan, and Ontario can compare what they saw or heard during this rare cosmic event. The sky literally exploded over Northeast Ohio today!

AI really can help education: Randomized controlled experiment on high school students found a GPT-4o powered tutor that personalized problems for students raised final test scores by .15 SD, "equivalent to as much as six to nine months of additional schooling by some estimates"

@jacecraftmiller The latest GLM imagery (1301Z) does suggest that the boom was a result of a meteor.
