These stars, as well as a number of others, are in reality enveloped by nebulae mostly of their own making. They're incredibly bright, and would probably be as bright as they seem in SE if it wasn't for the nebulae. One of them even ends up outshining Sirius as the brightest star in the Earth sky. Eta Carinae and the brightest star we know of, which is in the LMC and is actually visible with the naked eye from Earth in SE (:O) and other Wolf-Rayet stars also look too bright because of their lack of nebulae.

I wonder if in the far future some version of SpaceEngine might feature realistic distribution of dust and light extinction? That would make navigating around the galaxy a wonderful and challenging experience.

This is something I had considered too. For instance in my video, Deneb is one of my beacon stars en-route to finding Earth, but in reality it may not be possible to find at ~25000 lys away when viewed from above the galactic plane. smile

There would be very little dust to obscure your view of Deneb when viewed from out of the galactic plane. The only stars that would be difficult to see from outside the galaxy would be ones embedded inside dust clouds or located very near them.

Yeah, Deneb would probably still be a great star for astrogation in reality. Eta Carinae would lose most of its use, though. My method only uses it to find the right part of the galaxy to find Deneb, so it would probably still work in reality if you remembered where Deneb was.

Is anyone still able to do this in 0.9.6?

The stars seem to have changed magnitudes and as far as I can tell some methods in this thread no longer work

My way still mostly works, because it avoided the supergiants that have been debrightened. I used Eta Carinae as a marker of where Deneb was, though, so Deneb is a bit harder to find, but it's doable by keeping an eye on the position of the MAggelhannic clouds. After that, it's still mostly the same. The Barkhatova cluster looks different and less obvious, whioch makes finding Rigel from Deneb harder, but after that it's smooth sun-sailing.

I can still do it as well. My method did not rely strongly on Eta Car, Deneb, etc, so they don't affect my ability to find the Sun. One slightly important thing for me is making sure that the Orion Nebula is in the correct location (in the default release it is too small and too close to Earth). But it could be removed entirely and not affect whether I could do it, it's just a little helpful.

It would be nearly impossible to find the Milky Way from intergalactic space now though, with procedural galaxies masking the "butterfly" shape of the galaxy catalog.

That's very hard now, indeed. You would need to learn to recognise the shapes of the Virgo cluster and supercluster well to do it; and even then it would be very hard.

And... it's done for me !!

Epic is the only word to describe the moment when your are facing a star, and when you click on it, you see "Star Sol" !

I sometimes try this aswell by simply trying to find the brightest stars. Typically Rigel, Canopus, Sirius, Capella, etc...

But I usually get there by trying to detect Deneb first surprised biggrin

Another way I find Earth is by making up the Orion's hunter figure and its belt, or by measuring the distance of Rigel xD

You guys are crazy... You know that? shok lol

I didnt tried yet... But I dont think I cant do it because I lack knowledge of star positions in relation to Earth. Actuallly, in relation to anywhere... rolleyes
Maybe I will give a try one day (with Robbie guide video). smile

I love this. I can find my way to earth using the Deneb, Rigel, Orion Nebula, Nihal, Capella, Sirius, Sol path. But the coolest thing is looking out at the night sky and realizing all of these stars are easily visible to the naked eye in the northern hemisphere during the winter. Starwalk app for the iphone helped, and now I can recognize them from their position relative to Orion.

Hey guys! Nice forum you have here!

Here's my more or less unambiguous way to find Sun from wherever you are outside the Galaxy.
I'm pretty sure after some modification it should also work IRL, lol. But. At first it is recommended to do it with HUD on. Second time you will not need any HUD's for sure.

At first, place the center of the Small Magellanic Cloud exactly between you and the core of the Milky Way in such a way, that Big Magellanic Cloud is at exactly 3 o'clock position (to the right). There's only one way to do so, so it should be simple. The small Magellanic Cloud in your view point shoulld lie exactly on the core of the Milky Way. So, you look at the galactic core straight through the small Magellanic cloud.

Now, select the reasonable speed and go to the beginning of the third Spiral (which is at 1 o'clock position right above the Magellanic Cloud in your preset). The first, the only and the brightest star which you will see on your way is our good old friend - Deneb (it's a superluminous white giant, after some training you will not be able to mistake it for anything, everything else are globulars, so it is the brightest and the only visible star on your approach way).

Got to Deneb? Good. Now the same trick. Place you point of view in such a way that Deneb lies exactly in the center of the Small Magellanic Cluod and the Big Magellanic Cloud is exactly to the left of both at 9 o'clock position. On the same horizontal line, further to the left of the Big Magellanaic cloud, there should be Rigel. It is the first and the brightest blue star which lies exactly on this line (your point of view now should be: Deneb lies exactly on the center of Small Magelannic cloud, horizontally exactly to the left of it is Big Magellanic cloud and on the distance 2x the distance from Deneb to BMC, further to the left of BMC there's only one bright blue star-Rigel).

But don't go to Rigel, look to the south of it a little bit. There should be one red star exactly below it, which lies right at the edge of the Milky Way dust cloud. It's Betelgeuse. From this point, you just need to recognize this constellation. After doing it with HUD on you will remember there is it and next time HUD will not be needed. Betelgeuse is right next and "south" of Rigel.

Go to Betelgeuse. From now on, you are on a straight highway to the Sun. You don't even need to turn a lot. Also - Orion Nebula is seen with the naked eye from Betelgeise (as well as from the Sun). But we don't need it, though.
Here comes another trick - place the bulb of Betelgeise exactly between you and the core of the Milky Way. It should cover the core completely, the spirals of the Milky Way should be seen as a horizontal line dividing your screen. Make sure the Magellanic clouds are somewhere "above your head" and not below, i.e. above the horizntal line of the Milky Way (it's important). Right next to the Betelgeise, at exactly 3 o'clock position, you will see the only one bright blue star (in your point of view it lies exactly on the horizontal Milky Way dust cloud). It's Bellatrix.

After arriving to Bellatrix, do the same - place it exactly like you placed Betelgeise on the previous step. Look at the 5 o'clock position from Bellatrix. There will be only 2 brightest red stars seen in this position, they are very close to each other. Pick the lower one and go there. It's Aldebaran.

After arriving to Aldebaran, do the same trick and place it as was described above (you was on a straight highway to the Sun from Batelgeuse, don't even need to turn much). Now look exactly below Aldebaran, at 6 o'clock position. There should be a square constellation of three blue stars and one red. Right in the middle of this square is our Sun. It looks like the tiniest and the most insignificant piece of crap. Its position in this constellation is easy to remeber in any way you wish. But also remeber - first time you do it with HUD on. Everybody can invent his own way of finding the Sun from this little constellation right below Aldebaran. That's it.

So, the highway from the outside of the Milky Way to the Sun loooks like:

Deneb--Betelgeuse--Bellatrix--Aldebaran--Sun.

Each step requires doing unambiguous and easy steps, like placing the star exactly between you and the core of the galaxy.
The way from the Sun to any known star is easy to construct in the same way, you just have to remember - Orion Nebula is seen from Solar system with the naked eye (in this game). Once you got there - you are on the crossroads.

That was really exciting.
