Goes -16 Weather Satellite is designed to detect the brightness of lightning. On Saturday, he saw the asteroid.
On Saturday afternoon at 4:25 pm, meteorologists noted unusually bright flash signatures on the Caribbean waters of 170 miles south of Puerto Rico.
Its light was as big as the Rhode Island – which was much larger than the lightning strikes. Plus there were no clouds in this area.
We will tell you what is true. You can create your own look.
One day, more specifications, analysis and extras
It was something else. The answer is something out of this world.
Scandal cases were detected on San Juan's radar national weather service. It's a tatell sign of meteor or asteroid effect.
How big was that? About 13 to 16 feet diameter or car size.
After entering the asteroid atmosphere, Spaceweather.com reported that the broad Nuclear Test Ban Treaty Organization includes "airways" associated with the explosion at Infrasound Station in Bermuda.
Its recording station is more than 1,000 meters away, where an asteroid has hit, and yet the station "has heard".
But normal sound can not travel as easy; If it is possible, everyone in Miami, Cuba and Puerto Rico should hear the blast. It was a different kind of sound: Infrasound.
Men can detect sounds between 20 to 20,000 hertz. It is the measurement that how often vibrate every second air pockets, in our ear, the sensor stimulates the receptors that process the sound.
Dogs can hear frequencies two times higher – near 40,000 hertz – that's why they will trample on a whistle which we can not hear.
Once you reach the lower side of the spectrum, you are speaking "infrasound". The infrasound wave can have only a couple vibration per second, for which our frequency can be very low. But that does not mean there is no sound.
The explosion of asteroids caused the dramatic infrasound signal in the form of "airwave" which plunged around it.
According to the Wife Vacar image shared by SpaceWeather.com, asteroid is divided into at least three pieces. An explosion of more than 6,000 tons of tunti was released from the blast, which was a 200-ton fireball.
Because the infrasound waves are very long wavelengths, they can travel at a distance.
By linking the knowledge that asteroids were struck with the magnitude of the signal taken in Bermuda, Meteorologist Peter Brown of Western Ontario University could conclude that he was "asteroid of a nearby multi-meter size" asteroid.
Astronomy of the University of Hawaii wrote that this particular asteroid was probably too small that it could enter the Earth's atmosphere (SpaceWeather.com wrote small pieces of asteroids, which are known as metroids, which probably spray the ocean surface).
But Spaceborne objects can threaten to some large earthquake, in vogue in February 2013, evidence has found that more than 1,000 people have been injured in Russia's Chelyabinsk.
NASA has identified most of the major objects in the Near Earth, if it is struck, could lead to global disasters (expected to happen once every 700,000 years). But finding small objects to hurt effective effects is a challenge.
Called "Breakthrough", Astronomini University of Hawaii announced that it had found a small number of incoming asteroids in advance in the press statement in advance.
His telescopes observed "asteroid" four times in a 30-minute period. Asteroid struck almost seven hours before it was.
"At that time, the asteroid was just [310,000 miles] From Earth – or 1.3 times the Moon. "
When matching data from other telescopes 100 miles away, "Asteroid's entry path was significantly improved", and it was "probable" that Earth would attack Earth.
It speculates that Saturday's asteroid can be detected almost half a day in advance, like the 2013 Chelyabinsk event – with most days – many days It was a "small house" size.
"For the first time, astronomers from the University of Hawaii have shown that their ATLS and Pan-Stars surveys could give telescopes enough warnings to take people away from the impact of asteroids," the organization wrote.
