A black hole is a region of space and time with such a strong gravitational acceleration that nothing can escape, not even light. It is said that these cosmic phenomena are formed when massive stars collapse at the end of their life cycle, falling on themselves and engulfing other black holes to form what is called a supermassive black hole. The scientists stayed a little hot after receiving a ticket in the front row to see this event unfold more than ten years ago, thanks to one of NASA's telescopes.
The YouTube series "Monster Black Hole" revealed how researchers around the world were on alert.
The narrator revealed: "On March 29, 2008, astronomers around the world were alerted by an observatory in orbit called Swift.
"He had recorded a flash of gamma radiation, a kind of ultra-high energy light that is the signature of a cataclysmic event.
"Swift automatically retransmitted the information on Earth and, in a few seconds, robotic telescopes in North and South America turn their gaze to the rising light.
"Astronomers enter the data to see the brightness and power of the flash."
The series then revealed how researchers quickly worked to calculate what was happening.
The narrator added, "In giant observatories in Chile and Texas, they focus on and use specialized instruments to divide the light into different wavelengths.
"It told them how far the light had traveled to reach the Earth.
"What they discover, is that it was seven and a half billion light years away, halfway to the visible universe.

"Tom Vestrand is leading a robotic telescope project at the Los Alamos National Laboratory in New Mexico.
"He has been following high energy gamma ray bursts for more than a decade and has never seen anything like that."
Dr. Vestrand told viewers, "It was the brightest thing ever detected by humanity.
"Traditionally, we think that astronomy is very slow, but it's something that has been traveling for 7.5 billion years.
"Arrived here and for 30 seconds, it was surprisingly brilliant a few minutes later, which meant it was still showing signs of saturation."
The narrator concluded by revealing why the scientists had determined that it was a black hole.
He continued: "It was so bright that it was visible to the naked eye.
"By collecting evidence from terrestrial and space telescopes, astronomers determined that the flash was a narrow but intense beam of light.
"Most likely, this has spread the birth of a black hole.
"This singular moment is the culmination of a chain of violent events at the heart of a big star."
Previously, a team of Japanese scientists using the Atacama Large Millimeter Array (ALMA) telescope had been revealed captured details of a previously unknown structure located near the center of our Milky Way.
Their analysis of the movement determined that it was a black intermediate mass hole whose cloud was labeled HCN – 0.009-0.044.
The lead author of the study, Shunya Takekawa, wrote in March: "A detailed kinematic analysis revealed that a huge mass, 30,000 times greater than that of the sun, was concentrated in a region much smaller than our solar system.
"This and the lack of object observed at this location strongly suggest a black hole of intermediate mass.
By analyzing other abnormal clouds, we hope to expose other silent black holes. "
The team's discovery suggests that many other similar black holes could be hidden around the center of the Milky Way.
Their theory suggests that intermediate-mass black holes could fuse and expand by swallowing surrounding materials to form supermassive black holes.
