European Space Agency (ESA) has published a terrific snapshot of galaxy NGC 5468, which is 130 million light years from us.
Thanks to new technical capabilities, scientists have researched in This galaxy has many supernovae whose brightness is suddenly increases and then fades out smoothly.
Some supernovae at the end of their life cycle suddenly shrink and explode. Others where there is a double stellar system, a white dwarf similar to our sun merges with another star, resulting in a powerful explosion.
The ESA also reported that over the past twenty years in this scientists discovered five supernovae of both types in the galaxy.
Previously, American astronomers hypothesized that in the past, of our Sun was “fellow”, but because the solar system was double star system, which is most characteristic of our galaxy. Such conclusions of astrophysics were made on the basis of the analysis of radio waves emissions coming from a remote dust cloud that The past was supposedly the second star in our system.
