A supernova explosion first seen from Earth 436 years ago has come back to life for astronomers in a time-travel-like astronomical twist.
By observing light from supernova SN 1572 that was slowed on its trip to Earth by dust particles, scientists can watch the outburst now as it would have looked originally.

  • Wats the song called?

  • interesting video and very informative

  • I don't think that's what it looked like

  • @bweazel all i did was read the description. apparently reading is over your head.

    the people who made the video say it's light photons slowed by dust particles.Whatever the rest of you are saying is irrelevant.

  • @stayinstock Obviously it's way over your head as well. Apparently, these people are saying it reflected off a dust cloud, not traveled through one and slowed down.

  • @handsupbud

    Go troll somewhere else.

  • @Matu1 Have you ever thought about committing suicide so you won't be bother by us any more?
