Last year, NASA announced that it had discovered 14 of the coldest stars it had ever recorded. The so-called “brown dwarfs” were, at that time, listed among the coldest known stars in our universe.
Now, employing the same instrumentation it used to detect last year’s brown dwarfs, NASA has identified six new, even-cooler orbs known as “Y-dwarfs.” Y-dwarfs are the coldest members of the brown dwarf family, which makes these stars the coolest of the cool. How cool you ask? Try cooler than the human body.
