Well, I haven't been doing very money, 60 symbols videos because obviously I don't live in Nottingham anymore.

We are in Sydney, Australia, and after my contract in Nottingham was over, I got a job, a postdoctoral position here in Sydney.

The Southern Hemisphere sees some stars different than what the Northern Hemisphere can see.

So if we use my my Australian prop here, this is gonna be the earth.

We're gonna pretend that this is the sun.

So the earth goes around the sun and the earth also rotates.

So if you consider the head is the Northern Hemisphere and the body is the Southern Hemisphere as it rotates and moves around the sun, this side can only see things that are up here.

And the body can always see things that are down here.

So some things we can see from both hemispheres, like Orion than certain constellations.

But certain things you can only see from the north, like the North Celestial Pole and from the South there things that you could only see, they're like the Southern Cross is probably the most famous constellation in the Southern Hemisphere.

We have a ll the really, really great Nibali the Northern Hemisphere has some good ones as well.

No longer hemisphere has has fantastic Galaxies.

We have a few notable ones, but I think the our part of the galaxy, which is visible here directly overhead, is just fantastic.

Look at just even naked eye of a nighttime.

You can you see all the dust lanes and or just the bright lights of a lot of beans and beans a star.

So maybe we are fortunate, Um, but I couldn't call it one way or the other.

So one of the highlights of the Southern Hemisphere is definitely the crux.

Is the official constellation the smallest of the official 88 constellations, and it also makes up the Southern the Southern Cross.

And then there's a couple other stars that are attached to it called The Pointers.

One of the pointers is Alpha Centaurus, which is actually the nearest star to earth.

So if you look at it through a telescope, it looks like a little double star and said that little group are the closest stars that we have to the Earth and the sun.

So Alfa Centauri is a big, bright one, but it's got its thinks.

We think it's actually a triple system, and one of those stars is Proxima Centauri.

And that's just a little bit closer than Alfa Centauri, right?

Well, the Southern Cross is so famous in the Southern Hemisphere that it's on legs, so it's actually on five national flags, including Australia.

You come here to Australia to see the sun skies, and I guess it's because we have a couple of really close Galaxies, majority clouds that are really, really close by to our galaxy.

So people want to say that, and there's Nibali within their and there are the biggest cluster of visible in the skies down.

So maybe we do have a bit of an unfair advantage.

So another thing about the Southern cross it.

You can usually see it from inside of the city, but when you go out of the city, you can see that, and then it is.

You start to see more and more stars and the Milky Way going across just behind the Southern Cross and what you notice did you start to see more and more stars that there's.

There's one dark patch just to the south of the Southern Cross, where there's decidedly few few stars there, so it's actually a dark nebula.

It's one of the few dark nebula that we know.

Um, head Horsehead Nebula in Orion is the other the other well known one.

But this is Actually it makes up the head of one of the the most well known indigenous constellations.

So it's the head of what's called the EMU.

I was quickly told it's not pronounced E Moo.

Is this big bird that goes all the way across the Milky Way in the sky.

And this dark nebula, the coal sack nebula, makes the head of this.

So just fascinates me that this culture actually has a story about the lack of stars in this region of the sky.

So my other favorite things in the South are actually Galaxies.

The large and small Magellanic clouds, but you can't see from the north, and it's such a shame because they're just brilliant.

They're they're fantastic to observe they've got, while the large Magellanic Cloud has the torrential a nebula in there, So that's a really awesome thing to go and have.

We'll get lots and lots of dust and swirling clouds and quite a few stars with it contained.

Within that you can see the big Milky Way shooting across the sky.

And then they're these two patches, kind of fuzzy clouds.

They almost look like, um, and one's big and one small.

They're both door for regular Galaxies, and there they make up part of the local group around around our galaxy, and they've definitely influenced some of the structure of our galaxy because they're just that close.

But the fact that you can see them in the sky and they're really big it's great.

The small majority cloud has equally has, um, interesting targets to look at some small nebulae there NGC 346 which is a fantastic looking nebula and also has 47 to kind of really, really, really close by, which is a fantastic globular cost of to observe.

So you, even visually, these things are fantastic.

When I first came to the Southern Hemisphere, it almost felt like it was an entirely new universe because there's there's so much that isn't in my intuition from growing up.

 You know, Orion is all of a sudden upside down, which kind of it makes me feel a little dizzy team to some degree, but it's just like I'm exploring an entirely new universe down here.
