Clouds of glowing gas mingle with dust lanes in the Trifid Nebula, a star forming region toward the constellation of Sagittarius. In the center of the lower photo, the three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque dust appear on the right, while other dark filaments of dust are visible threaded throughout the nebula. A single massive star visible near the center causes much of the Trifid's glow. The Trifid, also known as M20, is only about 300,000 years old, making it among the youngest emission nebulae known. The nebula lies about 9,000 light years away and the part pictured here spans about 10 light years. This image was created with the 0.8-meter IAC80 telescope on the Canary Islands of Spain.
The top photo was taken by the Hubble Space Telescope and shows a detail of the nebula. This close-up shows a dense cloud of dust and gas, a stellar nursery full of embryonic stars. This cloud is about 8 light-years away from the nebula's central star, not shown in this picture.
A stellar jet (the thin, wispy object pointing to the upper left) protrudes from the head of the cloud and is about .75 light-years long. The jet's source is a young stellar object deep within the cloud. Jets are the exhaust gasses of star formation. Radiation from the nebula's central star makes the jet glow.
The finger-like object to the right of the jet is a stalk. It is pointing from the head of the dense cloud directly toward the star that powers the Trifid nebula. This stalk is a prominent example of the evaporating gaseous globules, or "EGG's". The stalk has survived because its tip is a knot of gas that is dense enough to resist being eaten away by the powerful radiation from the star.
The images were taken September 8, 1997 through filters that isolate emission from hydrogen atoms, ionized sulfur atoms, and doubly ionized oxygen atoms. The images were combined into a false-color composite picture to suggest how the nebula might look to the eye.
In January, 2005 NASA's Spitzer Space Telescope discovered 30 embryonic stars and 120 newborn stars not viewable in visible light images.

"FILLS" (THE) "OPENING"
Today is Liberation Day in Poland. It is Pied Piper Day. Time to get rid of the rats. It is also Spooner's Day. Reverend William Archibald Spooner was prone to making verbal slips (Spoonerisms) where the letters were swapped - e.g., come and wook out of the lindow. So grab your binoculars and let's go "word botching!!"
