Check out the 4-dimensional analogue of the dedocahedron, the hyper-dodecahedron or the 120-cell (or hecatonicosachoron).
The image is a projection of this 4-dimensional object, visualised as a Schlegel diagram. The hyper-dodecahedron is composed of 120 dodecahedra, 720 pentagons, 600 vertices and 1200 edges.
The thinner the line, the further it is away in 4 dimensions.

Seeing a supernovae within hours of the explosion
For the first time ever, scientists have gathered direct evidence of a rare Wolf-Rayet star being linked to a specific type of stellar explosion known as a Type IIb supernova. Peter Nugent of the Lawrence Berkeley National Laboratory says they caught this star – a whopping 360 million light years away – just a few hours after it exploded.
