Our home Galaxy is the Milky way Galaxy.
It is in the form of a disk of stars with a blob of stars in the centre.
Our Solar system is near the junction of blob and disk, and the Southern Hemisphere looks towards the blob, which appears as a great glittering band across the night sky.
No. One of the better known constellations in the northern hemisphere is the big dipper. People in the southern hemisphere can't see this. In the south the well known constellation is the southern cross, and you can't see this in the northern hemisphere.
Rome, the capital of Italy, is in the northern hemisphere. You cannot see the Southern Lights from the northern hemisphere.
Yes. You need a telescope to see most galaxies. However, aside from parts of our own galaxy, there are at least three others that can be seen with the naked eye. In the northern hemisphere, the Andromeda galaxy, a spiral galaxy like our own "Milky Way" galaxy, is visible with the naked eye at times. In the southern hemisphere, you can see the Large and Small Magellanic Clouds, two irregular galaxies.
NO!
People do talk about them. You probably live in the northern hemisphere, so the Northern Lights are more relevant there. In the southern hemisphere, people would be talking about the Southern Lights, as that is what they might be able to see. Where they are, they would not be talking about the Northern Lights.
Yes. Quite clearly.
Polaris is always below the horizon, to an observer in the Southern Hemisphere.
The Southern Cross and Orion's Belt (and the rest of the Orion constellation) are usually in the southern hemisphere's sky. You can see Venus quite a bit too, but it's not a constellation.
No
southern hemiphere Because there is more land. Look up a map of the world and you will see that the Northern Hemisphere has the largest land mass,,,,not the Southern Hemisphere... Question is still open...
The Southern Hemisphere has more water than the Northern Hemisphere because around 81% of the Earth's water is located in the Southern Hemisphere. Additionally, the Southern Hemisphere has more ocean area compared to the Northern Hemisphere.
Tornadoes form in the southern hemisphere for the same reason they form in the northern hemisphere. The mechanics are the same. See the related question for what causes tornadoes
