Summary
DescriptionAstro 4D m45 cr anim.gif |
English: Pleiades - the movement of stars in -/+ 200 000 years. To view this picture you need cross-eyed viewing.
Slovenčina: Pohyb M45 za 400 000 rokov (-200 000 až 200 000 rokov). Do tejto hviezdokopy patria hviezdy, ktoré vidíme približne v rovnakej vzdialenosti a smerujú do spoločného bodu na oblohe. Ich zdanlivý smer pohybu na oblohe je vo veľkej miere ovplyvnený blízkosťou antapexu, kde sa hviezdy akoby strácali v diaľach. Pozn.: hĺbka 3D priestoru je modifikovaná logaritmicky, t.j. hviezdy, ktoré sa nám javia na dvojnásobnú vzdialenosť, sú v skutočnosti vzdialené až 10-násobne. Na prezeranie animácie treba zvládnuť tzv. škuľavé pozeranie.
