Explanation: The beautiful Trifid Nebula is a cosmic study in contrasts. Also known as M20, it lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star forming region in the plane of our galaxy, the Trifid does illustrate three different types of astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue reflection nebulae produced by dust reflecting starlight, and dark nebulae where dense dust clouds appear in silhouette. But the red emission region, roughly separated into three parts by obscuring dust lanes, is what lends the Trifid its popular name. Pillars and jets sculpted by newborn stars, above and right of the emission nebula's center, appear in famous Hubble Space Telescope close-up images of the region. The Trifid Nebula is about 40 light-years across. Too faint to be seen by the unaided eye, it almost covers the area of a full moon on planet Earth's sky.

One of the first objects I looked at in the sky when I bought my first serious telescope was the Triffid. The Southern sky from my back yard was fairly dark and I could just make out the Milky Way, or parts of it. I was so excited to actually find something on that Star map I was using. I could just make out the dust lanes. After a while it became more difficult to make out those “ faint fuzzies”, and I realized it was getting close to morning twilight.

I completely understand the fascination.

It’s the fascination, but it’s also the memories. That was almost 45 years ago. I don’t live there anymore, and there is a big gas station lit up like daytime looking in that direction. In fact, there is NOWHERE around here that I can get that kind of view again.

I wonder what equipment was used to photograph this. Was it an amateur astronomer? I don’t think it was from the space telescope. It didn’t say in the write up.

Yes, it was an amateur. Here's my Trifid. It's pretty close to our neighborhood at about 5,000 light years away.
