It’s an intergalactic ménage à trois that doesn’t contain Uranus.
Concept the 2020 “double planet” used to be spectacular? This weekend, stargazers can witness Mercury, Jupiter and Saturn proportion the sky as a part of a mind-blowing “triple conjunction.”
As a carrier to sky watchers, we’ve rounded up the whole thing you want to find out about this interstellar phenomenon.
What’s the “triple conjunction”?
