You may remember the meteor that burned up in the sky over Russia in February this year. It's the one that produced a shock wave that shattered windows nearby.
Now a report from the BBC in the United Kingdom says scientists used a global network of sensors to detect that shock wave traveled around the globe two times. The sensors were actually set up to detect nuclear testing, but the meteor's shock wave is the most powerful ever detected by the sensors.
The BBC says a report on this study revealing this information will appear in Geophysical Research Letters.
More than a thousand people were injured when the meteor burned up in the sky over Chelyabinsk, Russia, which is a city of about 1.13 million people and is located just over 1,000 miles east of Moscow.
