Behold: the 4 light years wide centre of M8, aka, the Lagoon Nebula – 4,000 light-years away within the boundaries of the constellation Sagittarius. To wit:
Visible light images show the glowing gas and obscuring dust clouds that dominate the scene. But this infrared image, constructed from Hubble Space Telescope data, peers closer to the heart of the active star-forming region revealing newborn stars scattered within, against a crowded field of background stars toward the centre of our Milky Way galaxy. This tumultuous stellar nursery’s central regions are sculpted and energised by the massive, young Herschel 36, seen as the bright star near centre in the field of view. Herschel 36 is actually a multiple system of massive stars. At over 30 times the mass of the Sun and less than 1 million years old, the most massive star in the system should live to a stellar old age of 5 million years. Compare that to the almost 5 billion year old Sun which will evolve into a red giant in only another 5 billion years or so.
