On October 19, 2022, NASA announced that James Webb Space Telescope has once again taken the high-definition image of " Pillars of Creation " after Hubble . Unlike the previous shots, the details of the "Pillars of Creation" taken by Webb , which is loaded with more advanced shooting, are clearer. In the background of the original empty column of the pillar of Creation, countless bright and shining stars appeared after high-contrast imaging.
(The pillar of creation photographed by Weber Telescope is clearer, and the originally blurry background is also spread all over the stars)
This is also the third time we have obtained the pillar of creation in the distant Eagle Nebula. Hubble Telescope took the pillar of creation nebula twice in 1995 and 2014. The scene presented in this small photo can reach 8 light years, and at least tens of thousands of stars shine in space. The three giant nebula pillars are 6,500 light years away from us. The huge nebula pillars provide power and matter for new stars. Several stars are nurtured in several pillars, so they are named the Pillar of Creation.
(The pillar of creation taken by Hubble is dazzling at first sight, but the scattered star background always makes people feel that there is nothing missing)
But just when the world is attracted by this beautiful photo, NASA astronomers unanimously agreed that perhaps the pillar of creation no longer exists. In fact, this is not the first time. As early as 2007, the mainstream view in NASA had already believed that the pillar of creation had been destroyed by the impact of the supernova that broke out 6,000 years ago.
Although the stars here are very dense and vibrant, through clearer photos, you can see several elderly stars surrounding the pillar of creation. Once the elderly stars start to burst out supernova , the energy released instantly can reach the sum of energy that the star can generate over billions of years. At that time, the high-energy stellar wind will easily blow away the basic structure of the pillar of creation. This beautiful cosmic picture will no longer exist and become a discrete cloud or irregular nebula.
The reason why we can still see the pillar of creation is because the distance of 6500 light-years, the light has to go through a delay of 6500 years before it can be captured by the Weber telescope. Perhaps in this long period of thousands of years, supernova has long exploded.
If astronomers estimate, in future observations, we are likely to photograph the destruction of the pillar of creation, which will provide more detailed information for humans to understand space. Speaking of the "Pillar of creation", we have to mention the photographers of the photo, Hubble and Weber Telescope. The astronomy community has long realized that the atmospheric disturbance of the earth is a huge obstacle to astronomical observations. Under the mask of the thick atmosphere, humans' eyes towards space are like a layer of fog. How to clear the clouds and disperse the fog and see clearer and more real space scenes has become the unanimous dream of astronomers.
The Hubble Space Telescope that launched in 1990 has brought space exploration into a new era. Hubble, which is orbiting over the earth, no longer has the interference of the atmosphere. Humans also look into the deep space through the sky patrol camera equipped by Hubble. The truly clear cosmic picture unfolds in front of people. In a flash, Hubble has been working in high altitude for more than 30 years, presenting countless beautiful starry sky scenes in front of people.
, which will be launched in 2021, will integrate the most advanced technology so far, and the exposure speed will be greatly improved. The photos that Hubble telescope will take weeks to expose it to obtain. The Webb telescope can only be completed in 12.5 hours. Webb's launch does not represent the end of Hubble's mission. According to the recent news released by NASA, Hubble will continue to work in orbit until 2040. The elderly Hubble and his successor Webb will work together to explore deep space.
On the road to space exploration, my country has come from behind. In 2024, my country's space surveying telescope will also be launched. In order to facilitate later maintenance and reduce costs, it will operate independently as the same orbit as the space station in. There will be more amazing influences in the future.
How big is the complete universe? Do there really exist cosmic boundaries?
. Some scientists infer that humans or the earliest civilization born in the universe?
