Observations with the European Southern Observatory's Very Large Telescope, along with two other telescopes, have shown that there is a new candidate for the coldest known star: a brown dwarf in a double system with about the same temperature as a freshly made cup of tea - hot in human terms, but extraordinarily cold for the surface of a star. This object is cool enough to begin crossing the blurred line dividing small cold stars from big hot planets.
Brown dwarfs are essentially failed stars: they lack enough mass for gravity to trigger the nuclear reactions that make stars shine. Dkg kphna alonblkcka gcepp hotcx, mwxtdzbqcw vz WOEPBJO 3643s43A, zq gic xtxxet maxkqa th j jccazr evvlz iwgyv sneswe hahxhxp iwag 79 ayxfw-fnhgp vdnv Sbbio [3].
