Read - How NASA makes 3D visualization of an exploded star

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

                           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.

Will You Inject Yourself with an Ancient Bacteria for Longer Life ? - Science Feed

By
Hii, This is Science Feed. In 2009, 3.5 million years old bacteria was found in the permafrost region on Mammoth Mountain in Siberia's Yakutsk Region. The bacteria was named 'Bacillus F' which was found by the Russian Scientist named Anatoli Brouchkov, head of the Geocryology Department at Moscow State University. After numbers of experiments, it was found that those mice which were injected with these bacterias have far better strength and immune system than normal mice. Each time the experiment was done, the results were the same. Curiously, One day Dr. Brouchkov injected himself with these 3.5 million old bacteria without knowing what would happen to his body. The problem was that scientists didn't know how the bacteria increase life span in mice. And about humans, not even a penny !!! He became the first guinea pig for the experiment In a statement, Dr. Brouchkov said that since the day he injected himself with, he felt more energetic and healthier. He eve...

Falcon 9 (SpaceX) - Science Feed

Hey, this is Science Feed, and this post is about Falcon 9, one of the most advanced rockets in the world. Before we get started, we request you subscribe to our blog so that you never miss our informative posts. We also recommend you follow us on these social media platforms. Facebook         Twitter          Reddit          Pinterest         Instagram Falcon 9 is the first reusable orbital-class rocket that can be used more than once. SpaceX has designed and developed it for payload transfer to Earth orbit and space. Over the time period of 10 years, Falcon 9 has been launched 85 times, in which 46 launches were able to land. Due to its capability of landing, SpaceX has saved costly parts of the rocket. This rocket uses rocket grade kerosene (RP-1, it is cheaper but less explosion hazardous fuel, which is a highly pure form of kerosene) as its fuel and liquid oxygen as an oxidizer.  In 2007,...

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...
