Hii, This is Science Feed. Today, We will read about 3D visualization of the exploded star (Crab Nebula) made by NASA.

This image was created by a team at the Space Telescope Science Institute (STScI) in Baltimore, Maryland; the Caltech/IPAC in Pasadena, California; and the Center for Astrophysics | Harvard & Smithsonian (CfA) in Cambridge. Massachusetts.
For the first time on July 4, 1054, Ancient astronomers of China found a strange thing in Taurus constellation.
Chinese astronomers saw an extremely bright star during daytime for weeks and for two years at night.
But today, this phenomenon is termed as the death of a massive star.
Now, How NASA exactly made the beautiful multiwavelength image of Crab Nebula. For this, NASA used Hubble Space Telescope, Chandra X-Ray Telescope, and Spitzer Space Telescope.
The Crab Nebula emits radiation and these radiations are studied with the help of these observatories. The emitted radiations travel about 6,500 miles and reach Earth.
The chemical elements such as Oxygen and Sulphur emit radiation of visible region of light. Hubble Space Telescope detects this visible radiation.
Similarly, X-rays are also emitted from the Crab Nebula but from the center of the nebula (pulsar). Chandra X-ray Observatory collects the X-ray part.

The radiation of the infrared region, which is produced by charged particles in a complex magnetic field, detected by Spitzer Space Telescope.
After getting data from Chandra X-ray Observatory, Hubble Space Telescope and Spitzer Space Telescope, the team first worked with two-dimensional images of nested structures of and wavelengths obtained.
Frank Summers, the Visualisation Scientist at Space Telescope Science Institue (STScl), said," Seeing two-dimensional images of an object, especially of a complex structure like the Crab Nebula, doesn't give you a good idea of its three-dimensional nature. With its scientific interpretation, we want to help people understand the Crab Nebula's nested and interconnected geometry. The interplay of the multiwavelength observations illuminates all of these structures. Without combining X-ray, infrared and visible light, you don't get the full pictures".
Watch this video to get better knowledge about the visualization of Crab Nebula. This video will help you a lot in understanding about how NASA's Universe of Learning materials use data captured from observatories and telescopes and analyze it to make 2D and 3D visuals of distant galaxies, solar systems, exoplanets, etc.
