One of the strongest impacts on Earth from space has been recorded. Thus, the sound shock wave caused by the collision of five galaxies reached Earth.
Oku.AzThe magazine “Monthly Notices of the Royal Astronomical Society” reported on this.
This group of galaxies was reportedly called the “Stephen Quintet.”
According to the information, in the cosmic chaos the galaxy “NGC 7318b” collided with the other four galaxies of the group at an incredible speed of 3.2 million km/h.
“In fact, it is a giant intergalactic debris field. The new ‘outlaw’ NGC 7318b crashed into the debris field, compressing the plasma and gas it contained. It then reactivated the plasma, causing it to glow in radio frequencies and probably started the star formation process.” “said the article.
Scientists have compared this shock front to the sonic boom of a fighter jet breaking the sound barrier.
It should be noted that the “Stefan quintet” is one of the most studied groups of compact galaxies. The “galactic crash” occurred 290 million light years from Earth.
