The Elephants Trunk
Wow, this one was a mission! This image took 25 hours to capture and about a month to process and edit. I kept tweaking trying to get as much details to show itself as I could. This was one of those projects I love where its nothing but a challenge and you feel like a better astrophotographer because of it. �The Elephants Trunk Nebula lies 2,400 light years away from earth within our own Milky Way Galaxy. The bright part of this image are ionized gasses that grab its energy from stars and make the gasses hot causing them to glow, emitting their own light source, while the dark parts like the trunk itself is really think galactic dust that doesn’t let light pass through on its way to us. To give you an idea on how big just the trunk is, its 20 light years long, which 20 doesn’t sound like a lot but to put it in perspective, it takes 5 hours for light to reach Pluto, so that’s pretty much the length of going to Pluto and back 35,040 times. It's a star forming region which means within that thick dust and gasses stars are being birthed. And I know what you’re thinking, How can you tell that stars are being born within that thick dust if we can’t see it? Thats a great question, the answer is through inferred telescopes like the Spitzer Space Telescope that can look through, almost like an X ray to humans. Just off frame would be a star mostly responsible for the energy to make this nebula glow called Mu Cephei. Its giant 1650x the size of our sun, and as big as the orbit of Saturn.�Anyway, as much as I enjoyed this process and the challenges it came with, the truth is, I’m excited to be done with it and start working on the other projects I’ve been working on over the last few months. �So with that…. Enjoy
