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

                 Crab Nebula
                           Credits : NASA, ESA and J. DePasquale (STScI) 
                                         and R. Hurt (Caltech/IPAC) 

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.

Thanks for reading

Theranos: A Complete Story - Science Feed

By
Theranos, the blood testing startup founded by Elizabeth Holmes that pulled off the biggest scam ever happened in the Silicon Valley. From 2003 to 2008 this company grew spectacularly, but as we all know whenever someone tries to have everything in the world someone else is waiting for them to grab them down to nothing just like what happened to Stratton Oakmont and it's very CEO Jordan Belfort . Stratton Oakmont was the biggest Wall Street firm till 1999 when Belfort accused of money laundering, stock market manipulation and fined for 190 million dollars. The same goes for Theranos, so lets begin from the beginning and see what was Theranos hiding in their vault. Elizabeth Holmes dropped out of Stanford at the age of 19 to start Theranos, which was then called Real-Time Cures. She was inspired both by her grandfather's medical career, and her summer 2003 internship at the Genome Institute of Singapore. Briefly after the internship she wrote up a patent application f...

What is Fermi Paradox? - Science Feed

By
Have you ever thought why we have not found any advanced intelligent organism yet? Or is there any other type of life form outside our planet Earth? These are the basic questions that come into mind when we talk about Fermi Paradox. Fermi Paradox Fermi paradox is the lack of compatibility or contradiction between the high chances of existence of extraterrestrial civilization in the universe and lack of evidence to find them or communicate with them. This was termed after the name of physicist Enrico Fermi. It casually came in head of Fermi during talk with his colleagues and he asked, "Where is everybody?". Early and Related Theories Before Fermi Enrico, the founding father of modern rocket science  Konstantin Eduardovich Tsiolkovsky, a  Russian scientist, proposed Zoo hypothesis. In Zoo hypothesis, it is speculated that the extraterrestrial civilization knows about our existence but instead of contacting us, they opt to do observation on us similar to animals in zoo.  Th...

Internet of Future - Quantum Internet

By
Have you ever wondered about how the Internet will look like in our future, how much powerful it will be, what are the various tasks it can do, etc. The answer to these questions is "Quantum Internet - Internet of Future". There are lots of reasons behind saying it is the Internet of Future. But before knowing the reasons, we should first understand - "What is Quantum Internet?". So, According to some experts,         The quantum internet is a network for transmitting qubits between distant locations. Hmm..., What are Qubits???                       Let me explain, When we use our classical computers, our information (more specifically our data) is processed or transferred in the units of 1 or 0, called "Bits". But in the case of quantum computers, it uses 1 or 0 or both at the same time (superposition state), named "Qubits"(sometimes quantum bit or qbit). Qubits are far more different from tra...
