Taureans are dark, determined and mysterious if you don't know them well enough.
So too is the constellation Taurus, which has just revealed its hidden depths to the APEX (Atacama Pathfinder Experiment) telescope in Chile.
The new images just released show a sinuous filament of cosmic dust you see in a bright red line.
It is not just long, it's more than ten light-years long.
Within its depths are newborn stars and the kind of dense gas clouds which forms yet more stars.
The revelation is all the more remarkable because these are hidden by cold, dark clouds when observed using visible light.
The LABOCA camera on the 12-metre APEX telescope, captured these astounding shots.
Sat on the plateau of Chajnantor in the Chilean Andes, at a 5000 metre altitude, the APEX is next generation submillimetre telescope, and part of the Atacama Large Millimeter/submillimeter Array (ALMA).
