Comparing the photos taken with the James Webb Space Telescope and the Hubble Space Telescope, it looks like this

A color photograph taken by the ultra-high performance space telescope ' James Webb Space Telescope ' developed as a successor to the ' Hubble Space Telescope ' was released in July 2022. The published photos are so high-definition that a large number of galaxies are reflected in the background, but even if you look at the photos alone, you cannot tell how much progress you have made from the Hubble Space Telescope. So, software engineer John Christensen published a comparative image of the same subject taken with both telescopes arranged at the same angle, so I summarized it.

The James Webb Space Telescope was developed by NASA as a successor to the Hubble Space Telescope, and after being launched in December 2021, various adjustments were made, and on July 11, 2022, 'SMACS 0723' The photo of is released. In addition, on July 13, 2022, photos of ' Carina Nebula ,' ' Southern Ring Nebula, ' ' Stephan's Quintet Galaxy, ' and ' WASP-96 b ' were also released. You can check each astrophotography and explanation of celestial bodies on the following pages.

A large number of photos of the deep space taken by James Webb Space Telescope have been released, and finally the photos of the 5 celestial bodies of the initial event are available --GIGAZINE

So, I arranged them so that I could compare the pictures of the same celestial body taken by the Hubble Space Telescope and the James Webb Space Telescope. You can compare the differences between each image by moving the slider left and right.

◆ SM ACS 0723
The celestial body is brighter in the photograph taken with the James Webb Space Telescope (right) than in the photograph taken with the Hubble Space Telescope (left). In addition, many celestial bodies that cannot be captured by the Hubble Space Telescope are also captured. In addition, if you browse the high-resolution version of the photos taken with the James Webb Space Telescope, you can see that the celestial bodies scattered in the photos are not single stars but galaxies with a large number of stars.

◆ South Ring Nebula
The photograph taken with the James Webb Space Telescope (right) clearly shows the gas spreading in outer space over a wide area. The background of the photo taken with the Hubble Space Telescope (left) is blackened, but the photo taken with the James Webb Space Telescope shows the celestial body bright in the background.

◆ Stephan's Quintet Galaxy
Compared to other images, the photos taken of 'Stephan's Quintet Galaxy' seem to have little difference between the two, but in the high-resolution version of the photos taken with the James Webb Space Telescope, even the stars that make up the galaxy You can see that you can shoot clearly.

◆ Eta Carina Nebula
Both of the following comparative images were taken of the star formation region 'NGC 3324' of the Etacarina nebula, but the image taken with the Hubble Space Telescope (upper left) is compared with the image taken with the James Webb Space Telescope (right). Because the shooting range was narrow, the comparative image was displayed so that the photos taken with the Hubble Space Telescope on the upper left of the photos taken with the James Webb Space Telescope were superimposed. There are a lot of stars in the back of the brown moyamoya at the bottom of the photo, but you can see that the photo taken with the James Webb Space Telescope can show more stars.

As you can see from the comparison image above, the James Webb Space Telescope outperforms the Hubble Space Telescope. In the future, the photographs taken with the James Webb Space Telescope and the collected data can be expected to further elucidate the mysteries of the universe.
