According to scientists, the Swift Orbital Observatory has recorded the first cosmic gamma radiation radiation on March 4, followed by the robot Master telescope receiving signals from the satellite, and 23 The second second began to capture the image.

About 8 hours later, Gran Telescopio Canarias, the world's largest optical telescope on Muchachos volcano on the island of La Palma in the Canary Islands, also participated in the monitoring of the gamma ray explosion.

Based on this telescope, scientists calculated the distance from Earth to the exploding star of 12 billion light-years.

It is estimated that the visible star size is 16.5, which is nearly 20,000 times less than the star with the weakest light visible to the naked eye.

Scientists say this ancient star explosion occurred eight billion years ago when the solar system and the Earth appeared in the universe.
