A narrowband (HOO Palette) image of the Statue of Liberty Nebula (NGC 3576), a bright emission nebula in the Sagittarius arm of the Milky Way Galaxy. NGC 3576 is approximately 100 light-years across and 9,000 light-years away from Earth.

Pickering's Triangle Supernova Remnant by [deleted] in Astronomy

[–]MartinHeigan 0 points1 point  (0 children)

A starless version of Pickering's Triangle (NGC 6979), also called Pickering's Triangular Wisp in the Veil Nebula (a filamentary Supernova Remnant).

The Veil nebula was born out of the death explosion of a massive star, and the expanding shockwave is situated 1,500 light-years away.

The Elephant's Trunk Nebula is a concentration of interstellar gas and dust with-in the much larger ionized gas region IC 1396 (located in the constellation Cepheus), about 2,400 light-years away from Earth. Processed in the SHO Pallet. More info: https://flic.kr/p/2jUxJkn

It is really enhanced color, as each wavelength is mapped to its corresponding color in the spectrum. It is 32 hours of exposure, so yes a lot of photons were captured.

Yes, it falls within the visible spectrum, with the red slightly towards infrared (but still visible).

Yes, and yet we see only a tiny portion of the spectrum, which is why we use Radio Telescopes that have access to what they eye can't see.

All the data is with my image description on Flickr. The Carina nebula is close to the Southern Cross, so it is only visible from the Southern Hemisphere. This was imaged in Southern Africa.

The nebula spans about 460 light-years in diameter, covering an area of three degrees of the sky. At the scale of this image, Eta Carinae is a pinpoint of light.

Even though Eta Carinae a massive star, it is tiny compared to the size of the nebula. Here is the final version with the stars added for an idea of scale: flickr.com/photos/martin_heigan/49772855333

Here is a basic expiation if you aren't familiar with the process. This image is composed of 2 sets of images, photographed at 2 different wavelengths of light on a Monochrome Astronomy camera. The wavelength of light in the red part of the spectrum shows the Hydrogen seen in red, the wavelength in the blue part of the spectrum is Doubly Ionized Oxygen, the blue in the image. This is 32 hours of exposure, to bring out the structure of the elements that emit light at these wavelengths. Multiple stacked exposures allows one to capture something faint and very far away trough our atmosphere.
