Space News for Everyone

In this post we are going to learn how to download specific raw image files of a celestial object which was taken by JWST (James Webb Space Telescope). It is easier to just download any image from the NASA or any other website but if you need to image process the raw data by your self, you need to download the raw image data of the JWST or any other mission from a database. MAST portal is one of the best image database you can find in the internet.   AstroView of MAST Portal  First thing you need to do is to search the keyword "mast portal" in the browser search.   Searching "mast portal"   Then click the first link in the search results as shown below. Then you will see the MAST portal website in the browser window.   The first link on the top of the search results     MAST Portal website in the browser window   After that you have to search the required celestial object in the search bar and click "Search" button. In this post I have shown how t...

Our solar system is mainly consisting of eight planets, Moons, our Sun and few dwarf planets. These planets are Mercury, Venus, our own planet Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.   Solar System with Dwarf planet Pluto (Image Credit: Pixabay.com and NASA/JPL-Caltech ) And also we have Pluto the dwarf planet. Previously Pluto was believed as a planet but after August 2006, the International Astronomical Union (IAU) down graded the status of the Pluto to Dwarf planets. 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 ...

P ulsars are type of neutron stars. And they emits radio beams across the Universe. They are made out of neutrons and they are highly magnetized. The size of a Pulsar could be about 1km of radius but the weight is many times larger than our Sun. They are actually remnants of star explosion such as super nova explosions. As I said before they are highly magnetized objects in the space and at the magnetic poles of the neutron stars the radiation emission happens throughout the universe. These neutron stars are spinning in high speeds. Some are spinning in hundreds of times a second around its spinning axis. When they spin around its axis, the radian beams spread across the universe like a light beam in a light house. And if we are in the line of sight, we can observe the radian beam. But they are not visible to the naked eye. To observe these pulsars, we can use large radio telescopes or radio antenna arrays.      Radio Telescopes (Credit: pixabay.com)   They are very ...
