WR 102ka

This Wolf-Rayet star lies in the Peony nebula next to our galactic center. It is one of the brightest stars in the milky way and a good candidate for a soon to come supernova. It had originally at least 150 solar masses, from which it probably has lost already a considerable part. WR 102ka is hidden behind thick layers of dust and therefore is hard to observe.

Constellation: Sagittarius
Distance: 26 000 light-years
