What mystery of the space movie Crab Pulsar does it reveal?

 



The Crab Nebula is an awe-inspiring celestial spectacle, and now, combination of new observations from NASA’s Chandra X-ray Observatory and Hubble Space Telescope, we can see its inner workings. Just when it seemed like the summer movie season had ended, two of NASA’s Great Observatories have produced their own action movie featuring the Crab pulsar and its incredible power.The Crab pulsar is a rapidly rotating neutron star located in the center of the Crab Nebula, roughly 6500 light years from Earth. It is approximately the size of Manhattan and is responsible for propelling matter and antimatter to near the speed of light. This incredible phenomenon was first observed by Chinese astronomers in 1054 AD, and since then has become one of the most studied objects in the sky.


By combining the power of Chandra and Hubble, astronomers have been able to compile a never before seen movie that showcases the inner workings of this cosmic generator. Bright wisps of matter can be seen moving outward at half the speed of light to form an expanding ring that is visible in both X-ray and optical images. These wisps appear to originate from a shock wave located at the center of the nebula, which show up as an inner X-ray ring consisting of about two dozen knots.These knots form, brighten, and fade as they jitter around, occasionally undergoing outbursts that give rise to expanding clouds of particles. By studying this phenomenon, astronomers hope to gain insight into how similar objects across the universe are powered. This movie is a testament to mankind’s ambition to explore our universe and unlock its secrets.


Mysteries of the Crab Nebula.


This nebula is home to one of the most fascinating objects in our universe – a pulsar. By taking both Chandra and Hubble observations, scientists are uncovering some of the most mysterious elements of this cosmic object. One of their discoveries was the presence of an inner X-ray ring located around the pulsar. According to Koji Mori of Penn State University, one of the authors of the study, “These data leave little doubt that the inner X-ray ring is the location of the shock wave that turns the high-speed wind from the pulsar into extremely energetic particles”. This shock wave is believed to be what powers the immense energy output from this pulsar. 


In addition to this discovery, there is also evidence for a turbulent jet that lies perpendicular to both the inner and outer rings. This jet has been described as “steam from a high pressure boiler” according to David Burrows, another coauthor of the paper. What makes this jet so special is that it is composed of matter and anti-matter electrons traveling at half the speed of light! 


The Chandra and Hubble observations have revealed a wealth of information about this cosmic object. Through these observations we are now able to understand just how powerful and mysterious pulsars can be. We are able to explore not only their fast-moving winds but also their violent jets and turbulent rings – all things that make them such unique cosmic phenomenon. The Crab Nebula has become a popular target for astronomers due to its amazing properties. With access to both Chandra and Hubble observations, astronomers are able to see ever greater detail into its mysteries.

In the triple-star system, KOI-5Ab is seen orbiting the primary star...

  KOI-5Ab continues to be a topic of discussion for researchers, as koi-5Ab has been seen orbiting the primary Star, confirming it has also been announced.  koi-5ab revolves around the primary star, it was thought to be a planet half the size of Saturn in a planetary system, and was the only other planet candidate to be detected by the KOI-5Ab mission. Kepler mission operations were initiated by NASA in 2009, by the end of spacecraft operations in 2018, the Kepler spacecraft had discovered 2,394 exoplanets, or planets orbiting stars beyond our sun, and about 2,366 exoplanets such  There are also those, which are still to be confirmed. David Ciardi, chief scientist at NASA's Exoplanet Science Institute, says the KOI-5AB was abandoned, because it was complicated, and we had thousands of candidates, and we were learning something new every day from Kepler, so that the KOI  Mostly forgot to -5.

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy.  And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light.  It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth.  Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower.  Today it is about 158 ​​million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon.  The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun.  During those periods, to operate the space shut...

A cluster of three galaxies was imaged with the help of the Hubble telescope's camera.

Using the Hubble Telescope's Advanced Camera (ACS) and Wide Field Camera 3 (WFC3), a cluster of three galaxies was imaged.  As shown in the image, the two galaxies have merged, scientists say, just as the two galaxies in the upper right appear to be interacting with each other, it is, in fact, stars.  Its long trails and the gas spreading from both of them gives the impression that these two have just collided with each other very fast.  In the lower left of the image is the bowling-ball-sized galaxy. Scientists say that the interaction between two galaxies occurs over a long time period, however, rarely will the galaxies collide with each other.  These galaxies are so close to each other in space that they form a cluster, which scientists have named NGC 7764A.  The mass between these galaxies has caused the formation of a shape at the end that, from the point of view of our solar system, resembles the starship known as the USS Enterprise from Star Trek.
