Messier 50

NGC 3718 is either a lenticular or spiral galaxy found approximately 52 million light years away in the constellation Ursa Major. The galaxy type is ambiguous due to the spiral arms, but they shape of these arms does not appear to follow the typical spiral outline.It has a warped s-shape, possibly due to interaction with NGC 3729, another spiral galaxy located 150,000 light-years away pictured in the top left of the image.

As the image above shows, the galaxy appears mostly yellow. This color generally resembles an older galaxy with less ongoing star formation and more old age star clusters comprising the halo. A more detailed, contrasting image of the galaxy from Heaven's Mirror Observatory shows a much bluer image. This indicates a large amount of young stars and ongoing star formation. Though this image was most likely filtered and altered to accent it's aesthetic beauty, there is much more detail and much of that detail can be attributed to much more observation time and techniques that were able to be explored in this course.

The image below is taken of NGC 3718 in the radio wavelength. This galaxy appears to have relatively low energy levels compared to other galaxies with a large, emitting center. The entire galaxy as a whole is emitting levels of radio radiation at the 20 cm wavelength.

20cm Wavelength imaging

Another image taken in a non-optical wavelength of 1.6 microns is shown below. This is in the infrared wavelengths, also known as "heat." The lack of infrared wavelength means that the galaxy is very cold, especially compared to other galaxies of similar size. There were no images that could be found in the X-ray section of the EM spectrum, indicating that there are very low levels of x-ray radiation due to lack of energy to emit such wavelengths.
