A massive boom heard Wednesday night over Puget Sound on the northwestern coast of Washington was most likely an exploding meteor. Or that's what They want us to believe anyway. The American Meteor Society registered a dozen reports. Video above. Keep your eyes on the upper left of the frame.
"The more I read the more inclined I am to believe this was a fireball (which is a meteor that is larger and brighter than normal)," the American Meteor Society's Bob Lunsford said. "I'm certain now that this was a meteoric event."
Most meteors' explosions are heard about a minute or two after they explode due to the time it takes the sound to reach the Earth's surface, Lunsford said. Sound travels at 767 mph in standard atmosphere conditions, indicating this fireball exploded some 35 miles away.
"If this was larger than normal then the sound could have originated from a higher altitude. So a delay of 3 minutes is entirely possible," Lunsford said. "Meteors become visible at a height of around 50 miles so your estimate is well within that range."
Lunsford said because there was a boom, it's very likely there are small, rock-sized pieces of the meteor somewhere on the ground. When a meteor causes a boom, it's "pretty far down" in the atmosphere.
During the January 2019 total lunar eclipse, astronomers trained the Hubble Telescope on our moon in order to calibrate how future telescopes will look for possible life on exoplanets by measuring ozone levels.
Watch the skies! The peak of the Perseid meteor shower takes place overnight tonight! The bright quarter Moon will limit the number of shooting stars you'll see but you can still expect around 15-20 per hour depending on where you're at. The meteors are debris from Comet Swift-Tuttle burning up in Earth's atmosphere at speeds […]
Piloting a craft through Jupiter's atmosphere would be very hard due to massive bolts of "shallow lightning" and the equally scary giant "mushballs" of water and ammonia that fall like hail. To celebrate the 9th anniversary of Juno, NASA shared some cool illustrations and a visualization of what it would feel like to fly through […]

Physics may have been that class you sleepwalked your way through in high school. But while it might have just slipped under your radar throughout your academic career, you probably shouldn't have given it such shallow attention. Sure, we could focus on the immediate pluses of a career as a physicist, like the more than […]
If you're out of work…well, first, you have our sympathies. Right now, about 31 million Americans are drawing some form of unemployment benefits, which makes competition for virtually any job savagely fierce. But since nobody wants to wallow in the miseries of unemployment, the only legitimate course left open is to scrap like crazy to […]
