Nasa shared time-lapse photography video and reviewed the brightness changes of SN 20 18gv supernova.

The United States and the European Space Agency discovered a white dwarf at the edge of the spiral galaxy NGC 2525, 70 million light years away, and continued to observe the end of this white dwarf. According to the observation data of Hubble telescope, the initial brightness of this supernova explosion reached 5 billion times that of the sun, but its light almost disappeared after one year.

It is reported that NASA and ESA began to observe this supernova named SN 20 18GV in February 2018, which lasted for nearly one year.

However, Hubble's observation of supernovae also helps scientists to better understand the expansion speed of the universe. NASA added:

"Supernova explosion is not only a gorgeous cosmic fireworks, but also a milestone in measuring the distance between galaxies. We can use this to calculate the speed of flight between galaxies, and in turn we can estimate the age of the universe. "

Finally, NASA shared a time-delayed video recording the brightness change of SN 20 18gv supernova, which made us strongly realize that even the stars in the sky will not shine in space forever.
