Deep within the lagoon nebula is a feature often called the "hour glass"
which is often misinterpreted as a glowing nebula when, in fact, the hour glass shape has a novel cause.

Dust clouds are obscuring light from "a monster young star 200,000 times brighter than our Sun" (source ESA/HST)
Simply catalogued as Hershel 36, ionized light caused by this bright star,
near the centre of the true colour (left) and narrow band (right) views below
is being obscured by intervening dust clouds

In a manner similar to earthly clouds obscuring our Sun, this distant sun's light also has a silver lining.
