"NASA scientists have discovered stars that are cool enough to touch..."

"...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.
Brown dwarfs, and Y-dwarfs especially, are what astronomers often refer to as
"failed stars;" the low density of these astral bodies prohibits them from
fusing atoms at their cores, which in turn keeps them from burning with the
enduring heat and intensity typical of other stars".

Ps. Coolt...!
