The Spitzer Space Telescope (man, being a whoremonger has no consequences these days, huh?) has discovered a brown dwarf star that could be the coldest star in the universe. Its surface temperature could be right around 80 degrees Fahrenheit. That’s cool enough that water vapor could have gathered in its atmosphere, making it a star with fucking CLOUDS.
There’s some question as to whether this brown dwarf, which is a companion to a white dwarf (ain’t that always the way. Racism), is actually a star and not a planet.
For all the scientific details that I barely understand, read this article.
