For the first time in history, astronomers witnessed the death of a star thanks to the telescopes of the Hawaiian Observatory.
And it was truly a grandiose event …
Continuing to prove once again that there is so much more there, outside of planet Earth.
Read on to find out the whole story …
Now when it comes to space, the solar system and the beyond …
NASA is truly the experts.
The National Aeronautics and Space Administration is an independent agency of the United States federal government responsible for the civil space program and aeronautics and space research.
Some of the best scientists, engineers, astronauts and cosmonauts in the world have worked tirelessly on NASA since it was founded in 1958 to try to learn more about space and what lies beyond our humble home planet.
And it is absolutely impossible to deny how far they have come in the last 6 and a half decades.
Since its inception, NASA has spearheaded most of the US space exploration efforts, including the Apollo moon landing missions, the Skylab space station, and then the space shuttle.
NASA also supports the International Space Station (ISS) and oversees the development of the Orion spacecraft, space launch system and commercial crew vehicles.
And next to all of these achievements …
NASA’s global team continues to scrutinize outer space and the possibilities of other universes and worlds.
And many of their findings strongly suggest that is an life beyond Earth, such as detecting water on Mars and receiving radio signals from billions of light years away.
Pretty exciting, right?
Well, recently they filmed something amazing with ground-based telescopes, and people can’t believe what they were able to see …
Astronomers got front row seats in the last moments of the life of the supergiant star, which is located about 120 million light-years from Earth in the galaxy NGC 5731.
Prior to this extraordinary event, scientists believed that red supergiant stars would burn quietly before exploding and transforming into a neutron star, but this is not the case in this case.
This star collapsed abruptly and turned into a Type II supernova, which means that the star did not use up all the surrounding hydrogen before exploding …
“This is a breakthrough in our understanding of what massive stars do in the moments before they die,” said Wynn Jacobson-Galan, a graduate of the University of California National Science Foundation, in his review. statement according to CNN.
“Direct detection of pre-supernova activity in a red supergiant star has never before been observed in an ordinary type II supernova. This is the first time we have seen the explosion of a red supergiant star. “
The star was first spotted in 2020, just months before it went supernova.
They observed a supernova called 2020tlf using the WM Keck Observatory Low Resolution Imaging Spectrometer in Maunakea, Hawaii.
“It looks like a ticking time bomb,” says Raffaella Margutti, assistant professor of astronomy and astrophysics at the University of California, Berkeley. “We have never confirmed such violent activity in a dying red supergiant star when we see it emit such bright radiation and then collapse and burn up, until now.”
Jacobson-Galan and Margutti were still at Northwestern University at the time, which meant they had access to telescopes, which was “instrumental in providing direct evidence of a massive star going into a supernova explosion,” Margutti said.
“I am very excited about all the new ‘unknowns’ that were revealed by this discovery,” added Jacobson-Galan. “Finding more events such as SN 2020tlf will dramatically affect how we define the final months of stellar evolution, bringing observers and theorists together to unravel the mystery of how massive stars spend their last moments.”
