When you rotate a cube in three-dimensional space, its shadow on a flat surface looks like a square, changing and deforming as the cube turns. That shadow isn’t the cube itself, but a 2D projection of it. Now imagine doing the same with a 4-dimensional cube, also known as a tesseract. When it rotates in 4D space, what we would see in our 3D world is its shadow, a cube that appears to deform, stretch, and fold into itself. Just as the shadow of a cube hides one full dimension, the shadow of a tes

Eta Carinae • Visualization Explores a Massive Star's Great Eruption 8 The Violent Star Eta Carinae Model Is Based On Multiwavelength Observations 25.1.2022 • It was once one of the brightest stars in the heavens, easily visible to mariners navigating by the southern sky in the mid-1840s. But the star Eta Carinae quickly faded into obscurity after its brief outburst. Now, over a century and a half later, NASA space observatories (probing from infrared light through X-rays) have enabled astronome

The Shape of Sagittarius in Three Dimensions | Space Telescope Science Institute FriendsofNASA.org: This visualization reveals stars of the Sagittarius constellation in three dimensions. Watch as the familiar pattern on the sky distorts into a whole new perspective. The sequence starts with a view of the asterism called the "Teapot", the most recognizable feature of the constellation Sagittarius. In the background, like steam coming out of the spout of the teapot, is our galaxy, the Milky Way. T
