The article from Astronomy Magazine discusses an astronomical observation made by Team ShaRA from the Chilescope remote observatory located in the Atacama Desert. The team observed and studied two particular galaxies, NGC 3169 and NGC 3166, located in the Sextans constellation.

The intriguing aspect of these galaxies is that their gravitational interactions are gradually dismantling their spiral structure. In addition to the galaxies, the image captured by the team also displays distinct tidal tails arcing around NGC 3169, providing further evidence of their ongoing gravitational interactions.

The image was captured using a 1-meter scope and required approximately 17 hours of LRGB exposure. What makes this observation unique is the collaborative effort behind the processing of the image. The image was processed individually by each of the 15 members of Team ShaRA. The final image was a “superstack,” combining the individual results according to the results of a team vote, which essentially weighted the contributions.

This kind of collaborative effort in astronomical observations not only helps in capturing high-quality images but also allows for diverse interpretations and a more comprehensive analysis of the observed phenomena. This kind of work could lead to new insights and discoveries in the field of astronomy.

In conclusion, the observation made by Team ShaRA offers an intriguing glimpse into the destructive gravitational interactions between galaxies, while also showcasing the potential of collaborative efforts in astronomical research.
