In a previous post , we have learnt about how to download images of James Webb Space Telescope using MAST portal database. Today let’s learn how to convert FITS images in to TIFF image type using a tool called “ FITS Liberator ”.    FITS Liberator Graphical User Interface Note that, this post is for “Pixinsight” users and there is another method to process these images without using “Pixinsight”. The FITS type images cannot be processed using graphics software such as “Adobe Photoshop”. Therefore we need to convert them in to TIFF type images. TIFF images are uncompressed large images without any data lose. Let’s download the FITS Liberator and install. So type fits liberator and click the first link in the search results.     Searching FITS Liberator in the browser. After that, click the link “Download FITS Liberator 4”, as shown in the figure below. Then you will direct in to another page which contains all the download links for any required operating system y...

Also there is a asteroid belt in between Mars and the Jupiter.  In our solar system, the planets are categorized in to two. Inner Planets Outer Planets Inner Planets are innermost planets in other words planets which are closer to the Sun. And all of them are terrestrial planets.They have rocky and compact surface.Mercury, Venus, Earth, and Mars are inner planets. These terrestrial planets are quite smaller compared to other gas and icy giants but larger than dwarf planets. Outer planets are planets ...
