Gestern Abend habe ich ein einmaliges Ereignis fotografiert – einen Kometen, der an den „Säulen der Schöpfung“ vorbeifliegt.

There are currently two bright comets in the sky, c/2025 R2 (SWAN) and c/2025 A6 (Lemmon). As an astrophotographer, comets are my favorite thing to shoot — they are constantly evolving, unpredictable, and beautiful. Given the rare opportunity to photograph two around the same time, I booked a trip to the Chihuahuan desert in southern New Mexico to be able to observe these celestial visitors under dark and clear skies.

Last night, the fainter of the two, R2 (SWAN) made a fortuitous pass by one of the most famous nebula in the sky — the Eagle Nebula — which continues the well-known “Pillars of Creation” photographed by the Hubble Space telescope. That image was shot in “false color” to show the different gases present in the star forming region of the pillars. This image shows that area in its true color form — the vibrant red of the hydrogen gas which dominates the nebula.

I had planned this shot for months, but when the time came, clouds came in, obscuring the target. Thankfully, with only an hour before the comet set below the horizon, I was able to get clear skies and a half hour of good images.

This final image is a crop of a larger image showing the comet passing between both the Eagle Nebula, and the coincidentally named, Swan Nebula. You can see that image on [my instagram page](https://www.instagram.com/brennanmgilmore?igsh=MTNjejkwYzZzc3Q1dw%3D%3D&utm_source=qr).
