Zooming in on Binary Star System Apep | ESO

This zoom video starts with a wide view of the Milky Way and ends with a close-up look at the serpentine swirls of dust surrounding a newly-discovered massive binary star system. Nicknamed Apep after an ancient Egyptian deity, it could be the first gamma-ray burst progenitor to be found in our galaxy.

Distance: about 8,000 light years

The reddish pinwheel shown in this final image of this video is data from the VISIR instrument on the European Southern Observatory’s Very Large Telescope (VLT), and shows the spectacular plumes of dust surrounding Apep. The blue sources at the center of the image are a triple star system—which consists of a binary star system and a companion single star bound together by gravity. Though only two star-like objects are visible in the image, the lower source is in fact an unresolved binary Wolf-Rayet star. The triple star system was captured by the NACO adaptive optics instrument on the VLT.
