Space rock hit moon at 38,000 mph

It was a flash of light seen on the edge of moon during the total lunar eclipse of January 20-21, 2019. Now astronomers have analyzed this meteor strike, the first ever filmed during an eclipse.

Observers watching the January 20-20, 2019. total eclipse of the moon saw a rare event, a short-lived flash as a meteorite hit the lunar surface.
Astronomers say it’s the first time an event of its kind has been filmed.
A new analysis by Spanish astronomers says the space rock collided with the moon at 38,000 miles per hour (61,000 km/hour) excavating a crater 33-50 feet (10-15 meters) across. The study was published April 27, 2019, in the peer-reviewed journal Monthly Notices of the Royal Astronomical Society.
The January 20-21 total lunar eclipse was the last one until May 2021, with observers in North and South America and western Europe enjoying the best view. At 4:41 UTC, just after the total phase of the eclipse began, there was a flash on the lunar surface. Widespread reports from amateur astronomers indicated the flash – attributed to a meteorite impact – was bright enough to be seen with the naked eye.
Unlike Earth, the moon has no atmosphere to protect it and so even small space rocks can hit its surface. Since these impacts take place at huge speeds, the rocks instantaneously vaporize upon impact, producing a glowing plume of debris that can be detected from Earth as short-duration flashes. Jose Maria Madiedo of the University of Huelva is a study co-author.
