Project AstroFly Examples: A Small Fraction of Our Milky Way Galaxy in Its Simplified Wireframe
This image, generated by AstroFly,
shows what a small fraction of our Galaxy (in 3D) is mapped in visible light. The
trouble is that clouds of interstellar dust and gas are opaque to penetrating
visible light; thus, light coming from many directions is blocked by such
veils, which is evident especially in the galactic plane. In the above image,
our Sun lies at the center of the "globular cluster" of stars, veiled by
its neighboring stars because of the actual point of view. The young, hot,
blue stars are visible in the galactic plane, whereas the older, cooler, red
stars are above and below it.
To get this view in AstroFly,
follow these steps:
- Start AstroFly.
- Press F5 to hide lines and names of all the constellations,
and press F6 to hide names of famous stars.
- In the Main Control Panel, uncheck the box Limit Visual
Magnitude (from the Sun).
- In the Main Control Panel, select the By Same Size
for All Stars option.
- In the Astro-Fly-Through Control Panel, enter the
value 340 into the RA in Degrees field, enter the value 70 into
the DE in Degrees field, enter the value 100000 into the DFTS in
Parsecs field, and click the Fly Now button.
- In the Main Control Panel, check the box Mark Extent
of Our Milky Way Galaxy as Simplified Wireframe.
- In the Main Control Panel, enter the value 10 into
the FOV Angle in Degrees field.
- Rotate the view around the line of sight to orient the galactic
