You might not know it from looking at the sky, but there’s a meteor shower reaching its peak today. Hundreds of space rocks are whizzing through the atmosphere, but the timing is such that sunlight obscures their fiery demise.

That’s because the year’s most active daytime shower produces distinct, whining radar echoes. Head to Spaceweather Radio for a listen; you’ll know you caught one when you hear what sounds like a person rubbing a finger around a wine glass. (Here’s an example from a Geminids shower.)
