MSG 519

Overview

MSG 519 is one of the strangest objects found in the vicinity of the Milky Way, and the only example of what is known as a Boson Star within 1 million light years of Sol. This little ball of gas and bosons is located in the Magellanic Stream - a giant 'ribbon' of gas connecting the LMC and the SMC. Although it is located there, it did not form there. MSG (Magellanic Stream Geminga) 519 is in fact incredibly old - 13.71 gigayears old. It formed only 90 million years after the big bang.

Discovery

MSG 519 was discovered during the Magellanic Stream Survey, that lasted around 40 years, from 18286 to 18326 CE. It catalogued around 35 million objects, not including planets. Those were found as well, orbiting their parent stars.

Around 700 of these objects were not visible to the main cameras of the telescopes conducting this survey, and among them is MSG 519. These 721 objects were designated MSG, for Magellanic Stream Geminga (Geminga being both a reference to an ancient human dialect, which translated to "not there", and also a reference to the infamous neutron star, Geminga, which was hard to find) and were numbered 1-721, ordered by their discovery date. MSG 519 was the 519th one to be discovered of these.
