Telescope Hubble captured the first phases of a star that exploded 11 billion years ago, when the universe was only 2.1 billion years old.
Research published in the journal Nature and this is the first time supernova “beginning” of the history of the universe.

Painting Hubble Collect three different starburst moments.
supernova the star, which was 500 times the mass of the sun, was discovered thanks to gravitational lensing: when the galaxy’s gravity distorts and magnifies the light behind it, it allows telescopes to observe distant objects.
Light from individual moments of the supernova traveled through the lens at different distances and was actually slowed down by the enormous gravity of the lensing galaxy, causing all the different “paths” of light to arrive at the same time.
“It is very rare to find supernova at a very early stage because this stage is very short,” said Wenlei Chen, lead author of the additional study and researcher at the University of Minnesota School of Physics and Astronomy.
“It lasts from a few hours to a few days and is easy to miss even when detected close,” he added. “In the same exposure, we can see a sequence of images, like several faces of one person. supernova”.
Science thanks to Hubble
Hubble He has been working for decades and, despite the launch of the James Webb telescope, continues to do science.
Unlike the recently released Hubble look optically.
Hubble continues to make important discoveries, including this year’s discovery of the most distant single star ever seen, Earendel, whose light has traveled to Earth for 12.9 billion years.
POT D SpaceX agreed to explore the possibility of concluding a contract with Elon Musk’s company for the supply of a space telescope Hubble to a higher orbit in order to extend its service life.
