Astronomy Picture of the Day - Meteor Fireballs in Light and Sound

Explanation: Yes, but have you ever heard a meteor? Usually, meteors are too far away to make any audible sound. However, a meteor will briefly create an ionization trail that can reflect a distant radio signal. If the geometry is right, you may momentarily hear -- through your radio -- a distant radio station even over static. In the featured video, the sounds of distant radio transmitters were caught reflecting from large meteor trails by a sensitive radio receiver -- at the same time the bright streaks were captured by an all-sky video camera. In the video, the bright paths taken by four fireballs across the sky near Lamy, New Mexico, USA, are shown first. Next, after each static frame, a real-time video captures each meteor streaking across the sky, now paired with the sound recorded from its radio reflection. Projecting a meteor trail down to the Earth may lead to finding its impact site (if any), while projecting its trail back into the sky may lead to identifying its parent comet or asteroid.

Today's NASA post is a meteor video at the link above. This photo is a large meteor photographed over the Czech Republic.

Every time I start to think I’m smarter than the average bear I read something like this and remind myself that maybe I’m not all that smart.

It is thoroughly humbling, isn't it?

Didn’t hear it through a radio, but I certainly heard the roaring sound of a fireball meteor that went right over my house some 20 years ago.

Cool!

The last one covered about 1/8 of the earth’s circumference, about 3,000 miles.

I saw the strangest thing on Sunday morning around 530. I saw a well lit object travelling nne. It left a huge contrail that was shaped like a V. The contrail just stopped and the object faded off to the horizon. I wonder what it was.

several years ago one very clear spring night I was presented with the most spectacular meteor shower i have ever seen.

with what seemed like dozens per minute for at least a hour. the greenish glowing orbs streaked across the sky with the larger ones definitely producing an audible sizzling or crackling noise.
I’ve never thought about it till I read this post. thanks

I bet! The scariest one I ever experienced was on a Twin Otter flight over Cook Inlet from Anchorage to Kenai. Nice calm night and all of a sudden the entire cabin lit up from outside. I thought an engine was on fire until the pilot leaned back and told us that a meteor had just flown overhead. That one was the carbonaceous chondrite that landed on a lake in the Yukon right afterwards.

What part of the country do live? If it's somewhere in the SE U.S. you probably saw the SpaceX launch of the latest batch of 60 Starlink satellites.
