Add a one-line explanation of what this file represents
 This file is a stereogram. Stereograms are stereoscopic images or animations which combine left and right frames showing slightly different visual angles to allow for 3D perception.

The stereogram uses the side-by-side cross-view method. The left frame shows the right eye's perspective, and the right frame the left eye's perspective. It might be possible to view this image without a viewing device by crossing your eyes to visually combine the frames.

Summary[edit]

Description
English: 4D motion of Hyades.

The movement of stars in -/+ 15 000 years.

To view this picture you need cross-eyed viewing.
Slovenčina: 4D graf pohybu Hyád.

Pohyb hviezd za -/+ 15 000 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.: poloha hviezd o 15000 rokov je tá, ktorá je označená bledým väčším kotúčom na konci úsečky. Na prezeranie obrázka treba zvládnuť tzv. škuľavé pozeranie.
