A fireball flew across the sky of Australia. What was it?

Imagine you walking along the nightstreet and you see a huge green ball flying through the sky - what will you do? Most likely, you will immediately pick up the phone and start shooting what is happening in Instagram for Instagram or just on camera. This is exactly what locksmith Denby Turton did when a burning ball appeared in the sky above Australia at 1 a.m. on June 15, leaving a green mark. Unfortunately, his camera was not able to focus on an unidentified object and make it difficult to see it on video. But in Australia there was another hard worker who worked the night shift and shot a more detailed video. Scientific publications were contacted by eyewitnesses, and scientists talked about the origin of the fireball.

The person who provided the best videounusual event, became a technician named Mitch Brune (Mitch Brune). According to him, an unidentified object was visible for 30 seconds and he was able to quickly grab a smartphone to record a 17-second video. According to him, he was amazed at how a burning object illuminated the sky in green.

But bad luck - according to Eleanor Sense,the cameras they installed could not capture an unusual object. Researchers immediately dispelled the rumors of an alien spaceship and announced that it was either space debris or a cosmic rock. But the fact that people saw in the sky a part of an obsolete satellite burning in the atmosphere is hard to believe - in the sky you saw sparks from burnt metal parts.

According to Renae Sayers, employeesThe Center for Space Research, University of Curtin (Australia), the trace of an unidentified object was clean and even. Such features are characteristic of meteorites, and the outgoing greenish-blue color could be caused by the combustion of magnesium or iron, which made up the space object. The researchers could not explain the unusual glow with more accurate details, because 95% of the light emitted from the meteorite was caused by a burnt atmosphere.

But a green hue may hint thatthe object was far from Earth and did not pose a threat to us. According to Eleanor Sense, many meteorites burn green and turn orange only when they are close to our planet.

Since the approximate place of the fall of the object to scientistsunknown, they will not trigger his search. However, they are almost sure that the fallen something completely burned in the atmosphere. In general, scientists compared the possible size of the fallen object as a cross between a basketball and a washing machine.

Finally, here's an interesting fact for you - afterthe fall of large meteorites, large craters remain on the surface of our planet. In them, water begins to accumulate over time and thus meteorite lakes arise. Some of them are very unusual - in India there is a lake in which the water periodically changes color. What is the reason for this, read in this material.
