SUMMARY

Rusty Williamson, a sci-fi author, seeks a 3D map of the universe to plot a course between the Coma Wall, Earth, and the Great Attractor, specifically within a distance of 400 million light years. Recommendations include the Digital Universe from the American Museum of Natural History and a detailed map of the Milky Way recently unveiled by scientists. The discussion highlights the challenges of observing the Great Attractor due to dense galactic material, which complicates data collection in that direction.

PREREQUISITES
  • Understanding of astronomical distances, specifically light years
  • Familiarity with 3D mapping tools for astronomical data
  • Knowledge of galaxy structures, including clusters and superclusters
  • Basic comprehension of observational astronomy limitations
NEXT STEPS
  • Explore the Digital Universe tool from the American Museum of Natural History
  • Research the latest findings on the Milky Way's structure and mapping techniques
  • Investigate the challenges of observing the Great Attractor and related astronomical phenomena
  • Learn about 3D visualization software used in astrophysics
USEFUL FOR

Science fiction authors, astronomers, educators, and anyone interested in cosmic mapping and the structure of the universe.

Hello,

I'm a sci-fi author and need to plot a course with distances and galaxy (cluster and super cluster) stop overs between the Coma Wall, Earth and the Great Attractor. I've looked at a few online 3D universe maps and 2D maps but have not found anything ideal. Any suggestions?

Thanks so much for any help you can offer!

How about this one:

Don't know, whether you've already checked it.

400 light years is exceedingly close by. That's just a tiny fraction of the nearby stars within our own galaxy. It's about 10,000 light years to the center of our galaxy, for a sense of scale. The Coma cluster is over 300 million light years away. The closest nebula (the Helix nebula) is about 700 light years away.

Still, fresh_42's answer should be a good one. If that doesn't get you what you need, let us know.

That might be useful but some points. As already pointed out, 400ly is nothing in space terms.

Second, it's very difficult to get any data in the direction of the great attractor. Thats beyond our galaxy in the same direction as the centre of the galaxy, which is dense and hard to look through. That's the reason when you look at maps of the universe, it looks like a dumbbell. We simply can't observe very well within the plane of the galaxy.
 
Thanks for the replies! Work on book sidelined by home remodeling... [:-(] I'll check all this out in hopefully a few days...sorry.

Forget map showing Great Attractor...I forgot we can't see in that direction (unless I'm behind the times).

Thanks,
Rusty

PS: Whoops...sorry, I meant 400 million lg on OP.
