NASA’s two talented telescopes joined forces. Scientists took action to create a striking and colorful display. They combined data from both the Hubble Space Telescope and the James Webb Space Telescope. By combining the powers of the two telescopes, the Christmas Tree Galaxy cluster will be displayed in all its majesty. Here are the details…
Webb and Hubble working together to image the Christmas Tree Galaxy Cluster!
Different telescopes operate at different wavelengths. This means they can observe different objects in the sky. When data from various telescopes are combined, striking images that are impossible to obtain from any single instrument can be obtained. Hubble and Webb will also collaborate to image the Christmas Tree Galaxy Cluster.
Hubble looks at optical wavelengths like the human eye. Thus, it shows the galaxies it detects mostly in blue and cyan colors. But James Webb looks at infrared wavelengths, beyond human vision. Therefore, it shows the galaxies it displays mostly in yellow and red.
The NASA platform, established by the space agency NASA for space enthusiasts, is now available for free.
There are some transitions in the green parts of the image of the Christmas Tree Galaxy Cluster, representing parts of the spectrum visible to both telescopes.
Researchers named the massive MACS0416 cluster the Christmas Tree Galaxy cluster. Scientists have compared this galaxy to a Christmas Tree, both because it is so colorful and because of the flickering lights we find inside it.
In fact, this cluster is in the process of colliding. When the process is completed, it will form a huge cluster. This cluster has been studied by Hubble over the last decade in search of some of the most distant galaxies detected at that time. Webb then took up this work.
Lead researcher Rogier Windhorst at Arizona State University made a statement on this matter. In his statement, he said, “We are building on Hubble’s legacy by pushing to farther distances and fainter objects.” said.
In addition to producing a striking image, Webb also seeks answers to other questions. He also investigates so-called transient objects, which change their brightness over time. These can be supernova events, where a star reaches the end of its life and explodes in a large, bright event that quickly fades away. Of course, there are other possibilities. There may also be other types of objects that are magnified for short periods of time due to the influence of stars or galaxies.
