Trifid in Hydrogen Alpha

Next up is the Trifid Nebula in Hydrogen Alpha. This bright nebula is less than two degrees above the Lagoon Nebula as seen in the post a few days ago. Indeed, the bright wisps along the bottom of this shot are the northern bits of the Lagoon.

The Trifid, also known as M20 or NGC6514, is another stellar nursery where star formation is occurring as we watch. The dense gas and dust is being carved into a cavity by the stallar winds of these hot young stars within the nebula creating the bright core cut with dark lanes of dust that we see in this image.

To truly capture this region I need to take at lest one more frame of the area and put together the several resulting frames as a mosaic to cover this large and beautiful nebulae complex.

Science Images are Ugly

One of the questions that comes up often enough is what do the pictures look like? And that question is followed by… Where can I see them.

The problem… Science data is usually pretty ugly.

Keep in mind that the astronomers are often pushing the telescopes and instruments right to the limit. This means that the data is barely there, a trickle of photons that have come from unimaginably distant sources.

I have been in the observing room as the data comes in. I have watched over the telescope operator’s shoulder. It is strange to see folks so excited over a smudge.
