Ghost Galaxy: Hubble vs JWST Comparison Images

In the past period we have seen something Pictures great from tJames Webb Space Helicopterlaunched into orbit last December.

In recent days, others released by ESA have been obtained in collaboration with the Hubble telescope and which aim to Ghost Galaxy. The two telescopes made it possible to observe the galaxy in a different light (literally).

Over there galaxy M74 it is located in the constellation of Pisces about 32 million light-years from our planet and is oriented so that its galactic disk is clearly visible. It is about a spiral galaxy grand design which has prominent arms, making it possible to study the star formation process.

The observations from the two telescopes are based on different wavelength ranges. The Hubble telescope can collect the radiation that falls into theultraviolet is in the visible. The captured image shows hydrogen clouds due to star formation.

With the Webb telescope, on the other hand, you can see the Infrared radiation that can pass through gas clouds more easily than visible or ultraviolet radiation. This will allow you to go deeper and better understand the phenomenon of new star formation.

The resulting images can be superimposed so that you can see the same object with a different eye and obtain different information. Below are the images published by ESA.
