Easy There, Sunny

Behold: star forming region Sharpless 106, at the centre of which is the massive star IRS4 – one of very few stars to be younger than the human race. To wit:

Born only about 100,000 years ago, material streaming out from this newborn star has formed the nebula S106.  A large disk of dust and gas orbiting Infrared Source 4 (IRS 4), visible in brown near the image centre, gives the nebula an hourglass or butterfly shape. S106 gas near IRS 4 acts as an emission nebula as it emits light after being ionised, while dust far from IRS 4 reflects light from the central star and so acts as a reflection nebula. Detailed inspection of a relevant infrared image of S106 reveal hundreds of low-mass brown dwarf stars lurking in the nebula’s gas. S106 spans about 2 light-years and lies about 2000 light-years away toward the constellation of the Swan (Cygnus).
