Incredible! Germany and Russia jointly take X-rays for the universe!
肖恩 10月 13, 2020
The British “Nature” news network recently reported that the “Spectrum-Roentgen-Gamma” (SRG) mission jointly launched by Germany and Russia will detect millions of supermassive black holes and hundreds of thousands of stars.
The project is equipped with two independent X-ray telescopes: one is eROSITA built by Germany, and the other is ART-XC built by Russia. The combined ability of the two allows astrophysicists to observe the dim celestial bodies in the universe that do not emit light. At the same time, X-rays will be used for the first time to provide people with a new way to understand the accelerated expansion of the universe over millions of years. Draw a “space map” that has never been seen before.SRG
The mission’s chief scientist and astronomer at the Max Planck Institute for Extraterrestrial Physics, Peter Pliddhall, said that in half a year, the project can cover the entire sky.
The mission will detect the X-rays emitted by the plasma and plasma filaments between galaxies, thereby mapping the cosmic network covering approximately 100,000 galaxy clusters, and will also detect up to 3 million supermassive black holes and 700,000 in the Milky Way. X-rays from a star.
Astronomer Fabiano of the Harvard-Smithsonian Center for Astrophysics in the United States said that the mission will be a great observation, and the data returned will have a profound and unique impact on the entire field.
When people see an X-ray of their body, they will find that it is completely different from the body seen with the naked eye. What about the universe? A “cosmic X-ray film” can reveal to us how the untrackable dark energy affects the accelerated expansion of the universe, and how it shapes the structure and history of the universe.
So what machine do you need to take a human X-ray? Now let’s take a look at the latest smart digital U arm X-ray machine from Newheek .
The newly designed high-frequency and high-voltage generator, the exposure conditions are stable and accurate, while reducing the radiation dose while reducing the generation of soft rays, effectively protecting patients and doctors.
Simple and convenient body position display, according to the selected patient’s body shape and location, the exposure parameters can be automatically set, and can be saved and corrected.
New U-shaped design, accurate rotation angle, multi-angle photography, to meet clinical needs.
Reassuring safety function, fault self-diagnosis function can quickly and accurately judge the fault status, and can automatically protect, display the fault code, accurate, convenient and timely.
Using digital flat panel detector, stable performance, greatly reducing X-ray dose, full digital image management and transmission, fast and convenient.
Newheek is a professional manufacturer of radiological equipment, its main products are: U-arm X-ray machine, DR flat panel detector, image intensifier, etc. If you need these equipment, please contact us!
