An interactive view of star constellations

An interactive view of star constellations by Nathan Yau.

From the post:

When we look up at the night sky to gaze at the stars, we see small, glowing dots that we perceive almost as if they were drawn on a flat surface. However, all these dots vary in distance from us. View of the Sky by visualization developer Santiago Ortiz shows this third dimension of depth.

The constellations are placed on a sphere that you can zoom and rotate. This is an interesting view in itself, but select the perspective for absolute distance and magnitude, and you’ll see something completely different. It’s no longer a network that resembles a globe, and instead it morphs to a cloud of stars and randomness. Also see Ortiz’s first view of the sky that includes stars not part of major constellations.

Ah, the sphere is the Earth and the default setting, “absolute magnitude, placed on sphere.”

Now try “absolute magnitude, actual positions.”

😉

I could not do it but it would be nice to be able to select a star in the actual position display and get a popup of its display on the sphere.

To sharpen the contrast between what we “see” and what is “seen” from a different perspective.

I have seen something along these lines before. Suggestions/pointers?
