As we all know, objects in the night sky are very unequally distributed over the celestial hemispheres. People in the southern hemisphere enjoy a lot of really cool things:
- Milky Way center, probably the most noticeable feature of the southern sky
- Centaurus region, which is much brighter than the Cygnus region of the MW
- Magellanic clouds
- Carina nebula, Orion nebula
- Omega Centauri, 47 Tucanae
- Centaurus A
- The two brightest stars in the night sky, Sirius and Canopus, as well as the fourth brightest, Alpha Centauri
- Mars at closest opposition
- Mercury better positioned compared to equal latitudes in the northern hemisphere
- Even comets seem to favorize the southern hemisphere (McNaught, PanSTARRS, ISON etc)
These are some really cool objects and events, which are all located in the southern celestial hemisphere. This doesn't necessarily mean they are invisible from the north, but they are better viewed from the southern hemisphere.
I can think of a few things which are better seen in the north:
- Andromexa Galaxy, Triangulum Galaxy (nothing compared to the Magellanic clouds)
- Pleiades, M44
- Double Cluster
- A truly bright pole star (for now!)
- M81/M82, M53, M101
- M13 (a joke compared to ω Centauri)
- North American nebula (not nearly as impressive as Carina nebula...)
- Generally, the constellation patterns seem clearer in the northern hemisphere, but this might be due to Western bias
But that's about it. I envy those living in Australia, New Zealand and other southern locations, for having a much better night sky. Furthermore, since the southern hemisphere is sparsely populated, dark skies are much more common, and the skies seem clearer due to less pollution.
To residents of the southern hemisphere: Is there any object in the northern hemisphere that you can't see from your home, that you would want to see?
