Giant "Twisters" and star wisps in the Lagoon Nebula (M8)
|
This false color image reveals small dark clouds called Bok
globules, bow shocks around stars, ionized wisps, rings, knots and jets. The most
stricking feature is a pair of one-half light-year long
interstellar "twisters" -- eerie funnels and twisted-rope structures -- in the heart of the
Lagoon Nebula (M 8), which lies 5,000 light-years away in the direction of the constellation
Sagittarius.
The central hot star, O Herschel 36, is the primary source of the ionizing radiation
for the brightest region in the nebula, called the Hourglass. The blue "mist" is double
ionized oxigen. Green light shows ionized hidrogen, red light --ionized sulphur atoms.
