The blazing fire bridge is accompanied by a super-sound explosion lighting the American sky

Hundreds of Americans witnessed a shooting star across the sky, forming a green fireball blazing with brilliance, releasing energy equivalent to 10 tons of TNT explosives and making a supersonic explosion.

Meteors burn green light rushing through the sky in northern state of Milwaukee on the morning of February 6. Its crumbs are likely to fall into Lake Michigan, according to Live Science.

The meteorite fell on fire in the sky at an altitude of about 16 - 32km, 160km north of Chicago, according to the American Meteorological Association (AMS). More than 220 people sent reports to AMS confirming seeing the fireball at about 1:25 am, according to NASA Meteor Watch Facebook page.

Most reports come from people living in Chicago and Milwaukee, but reports also come from witnesses in Michigan, Indiana, Iowa, New York, Kentucky, Minnesota and Ontario, AMS said. At least dozens of videos of fireballs rush through the sky are shared online or sent to AMS, according to Mike Hankey, AMS executive manager.

A video about fireball was recorded by Jim Dexter of the Lisle Police Department in Lisle, Illinois. Dexter saw a dazzling light rush through the sky and quickly turned on the camera on the car dashboard to shoot the picture. Another video returned to a scene of fireballs passing by recorded from the camera on the roof of the University of Wisconsin-Madison's Department of Atmosphere, Ocean and Space Science. Many videos show that this meteor is particularly bright.

"The camera in the area indicates that supernova appears at a height of 100 km above West Bend, Wisconsin and moves northeast with a speed of about 61,155 km / h. It crumbles into small pieces at 34km above Lake Michigan. , 14km east of Newton town , " NASA Meteor Watch said.

The meteor also produces a supersonic explosion, produced when an object moves faster than a sound wave in the Earth's atmosphere. According to Hankey, meteor stars only produce supersonic explosions when they are intact long enough to plunge to relatively low altitudes, where the Earth's atmosphere is dense enough. Most meteor stars burn into fireballs that do not produce supersonic explosions. They often burn or break down into many small pieces before reaching low altitudes.

The supersonic explosion produced by the fire bridge was recorded by a sound station in Manitoba, Canada from a distance of 965km. NASA Meteor Watch speculates that the supernova explosion unleashes energy equivalent to 10 tons of TNT.

All information helps scientists better understand the meteor's shape before it comes into contact with the atmosphere. This is certainly an asteroid debris weighing at least 272kg and a diameter of 0.6 meters. Hankey commented that this estimate is quite modest compared to the actual size of the meteorite.

Based on radar data, scientists determine the crumbs of meteor stars landing on the ground. However, some pieces may fall into Lake Michigan and cannot be collected for research. Meteors are large enough to save ground debris only flying through the US about 3-4 times a year.
