3D Printing an Exploded Star


Create a 3D model of Cassiopeia A, the 300-year old remains of a stellar explosion that blew a massive star apart, sending the stellar debris rushing into space at millions of miles per hour. Data of Cassiopeia A was captured by NASA’s Chandra X-ray Observatory and combined with infrared and visible light to make the first ever free 3D model of an exploded star.  Small prints around 3 in/7.62cm in size take about 2 hours to print, depending on the printer type.

Printable 3d Chandra Spacecraft


Create a 3d model of NASA's Chandra X-ray Observatory. Chandra, which was launched by the Space Shuttle on July 23, 1999, is a telescope specially designed to detect X-ray emission from very hot regions of the Universe such as exploded stars, clusters of galaxies, and matter around black holes. Because X-rays are absorbed by Earth’s atmosphere, Chandra must orbit above it, up to an altitude of 139,000 km (86,500 mi) in space.
