Fiona Macdonald wrote an article titled, “A Wave of Ultra-Hot Gas Twice as Big as The Milky Way Has Been Found Rippling Through Space“, and explained how researchers suspect what could be the largest wave of super hot gas going through the nearby Perseus galaxy cluster. Supposedly, the wave, which is classified as a Kelvin- Helmholtz wave, has been traveling through space for billions of years and is twice the size of the Milky Way galaxy. These waves have been spotted going through our atmosphere as well as the surface of the Sun. According to researcher Stephen Walker, Perseus is one of the most massive and brightest clusters near us.
This article compares the Perseus galaxy cluster to our Milky Way galaxy, which is direct to what our conceptual objective states. In my notes from the lectures I wrote down three galaxies that are compared to the Milky Way and they are; the Spiral galaxy, Barred Spiral galaxy, and the Elliptical galaxy. In class, we learned a lot about the differences between spiral and elliptical galaxies. We did Lecture Tutorials on pages 139 to 142 which were titled Galaxy Classification, where we applied Hubble’s Classification Scheme.
Overall, this conceptual objective was informative because we learned about how to classify and relate other galaxies to the Milky Way. Honestly, before this objective I didn’t think, nor did I know anything about other galaxies outside of ours.
