Most remote star in Milky Way (0.9.7.1)

I want to travel to the stars in our galaxy that are furthest from the centre.
So far I'm about 21 kpc out along the galactic plane and what I thought would be empty space is still teeming with stars (example RS 8409-800-2-32-0)
If I zoom out too quickly (say faster than 400 pc/s) stars seem to stop generating, but I can "bunny hop" by repeatedly focusing on a star and travelling outwards at a slower pace. This seems to generate stars that otherwise would be missed.
How far out will be the last star before we reach the terrible void of intergalactic space?

Hi marasmusine. You can try turning up exposure and limiting magnitude for stars to help make the galactic boundaries, as SE renders them, more apparent. For the Milky Way, the galactic disk experiences a very sharp cutoff in star density at ~21kpc from the center, though some stars still generate beyond this boundary, to ~26kpc.

It'll be really tough to find the actual farthest out star, as it's likely to be a red or brown dwarf considering how many of them exist. At the edges of galaxies, star density is far lower than in spiral arms and that makes the map mode poorly suited for finding weak stars in these areas as you have to zoom out farther to find the more distant stars, and at that point the limiting magnitude is turned down to avoid cluttering the map with those weak stars in denser areas.



I occasionally stream at http://www.twitch.tv/magistermystax. Sometimes SE, sometimes other games.

That does help, thankyou.
So far I am out to RS 8409-2853-8-658540-0 - a yellow dwarf 28.130 kpc out. It's nice standing on a moon and watching the whole disc of the Milky Way rise over the horizon.

RS 8409-2853-3-260-0 is a lonely red giant 29.481 kpc out.

A related question: Is 100 kpc the largest galaxy diameter that SE generates?

I want to share with you this news! and because I don't feel necessary to create a new thread for this I post it here.

A research team has discovered the most distant star in our galaxy. It's a M type Giant star called ULAS J001535.72+
015549.6 and it's at 274 kPc from earth (min: 200 kPc ; max: 348 kPc). That is ten times more distant that the most distant star on Space Engine. Is more than a third of the distance to the Andromeda Galaxy from here (far beyond the magellanic clouds). And it's NOT an intergallactic star! It's part of the Milky Way's outer halo (considering the kinematic family of the star and the gravitational bound to the galaxy).



The scientific paper of the discovery is here for more precision:
http://arxiv.org/pdf/1407.2610.pdf

When will SE is going to implement this extremely far away stars? And what about Intergallactic Stars? This is amazing. What a panorama. What a void. The sky of a planet orbiting that kind of star would have a starless night. Immagine if we where born there. Maybe we wouldn't knew that there are diferent kind of suns or even that the sun is a star, we would consider our system the universe for a long time. But from here the Milky Way has an angular diameter of 21 degrees so they would have more knowledge than us about galactic morphology and formation.

For the sake of perspective I have taken a picture of what would look like our galaxy from there (taken into account only the distance to Earth and the angle from the galactic disk of the star, that is 59.69 degrees).

Amazing how we can picture something so small (in a galactic scale) so far away! smile
