NEUTRON STAR..

          Neutron star are create when large stars finished all of fuel and collapse.if you want neutron star, size of the star that's greater than 1.5 sun masses and less than 5 times the mass of the sun.

         if the star size is more than 5 times the mass of sun,star will and up as a black hole.but if the star is right in between those masses, it became neutron star.
    if the star size is less than 1.5 solar masses,than the star don't have enough material and gravity to compress the object down enough. you only get the white dwarf. this is what will happen to our own sun one day.
         the neutron star is formed when the star runs out of own fuel and collapses inward on itself. the protons and electrons of atoms are forced together into neutron star.since the star still has a lot of gravity, any additional material falling into the neutron star is super accelerated by the gravity and turned into identical neutron material.

          just one small spoon of a neutron star would have mass of over 5E12 kg.it is the weigh of about 3 burj khalifa building. a neutron star actually has different layers. astronomers think there's an outer shell of of atomic nuclei with electrons about 1 meter thick. below this crust, you get nuclei with increasing numbers of neutrons. these would decay quickly on earth, but the intense pressure of the gravity keeps them stable.

           when neutron star form, they maintain the momentum of the entire star, but now they are just a few kilometers across. this causes them to spin at tremendous rates, sometimes as fast as hundreds of times of second.

HOW ATM WORKS ?

HOW ATM WORKS WHAT IS ATM?           An ATM is simply a data terminal with two input and four output devices. Like any other data terminal, the ATM has to connect to, and communicate through, a host processor. The host processor is connected to an Internet Service Provider in that it is the gateway through which all the various ATM networks become available to the cardholder (the person wanting the cash).            Most host processors can support either leased line or dial-up machines. Leased line machines connect directly to the host processor through a four-wire, point-to-point, dedicated telephone line. Dial-up ATMs connect to the host processor through a normal phone line using a modem and a toll free number, or through an Internet Service Provider using a local access number via a modem.           Leased line ATMs are preferred for very high volume locations because of their thru-put capability, and dial-up ATMs are preferred for retail merchant locat

OUR CLOSEST GALAXY ANDROMEDA..                 Andromeda  is the largest galaxy in the Local Group, which includes the Milky Way, the Triangulum Galaxy, and dozens of smaller dwarf and irregular galaxies. A recent estimate gave Andromeda 700 billion solar masses. Our Milky Way is only 80% the mass of Andromeda. IMAGE BY :  jpl.nasa.gov                  The Andromeda galaxy was first observed by Persian astronomers, thousands of years ago, and was later cataloged by Charles Messier in 1764. He classified it as M31. In 1912, astronomers calculated its speed to be 300 kilometers per second, moving towards the Sun. Edwin Hubble first calculated the distance to Andromeda, by detecting Cepheid variables in the galaxy. He measured that it was 450 kpc, or 2.5 million light-years away; well outside the Milky Way galaxy.                Recent estimates have calculated that Andromeda Galaxy is about 220,000 light-years in diameter, almost twice the estimate diameter of the Mil

KUIPER BELT INTRODUCTION kuiper belt is an area of ou r solar system t hat is e stim ated to stretch across 20 AU of space.it is contains s mall asteroid and some big asteroid size of Pluto.this things made mostl y of ice and other g ases such as ammonia,nitrogen ,m eth ane and water. the kuiper belt ext ends from rough ly the orb it of neptu ne at 30AU to 55AU from sun.the main objects o f th is belt covers much of this r egion .   FAC TS ABOUT THE KUIPER BELT 1. there cou ld be more than a trillion comet nucl ei in the main body of the kuiper belt. 2.the largest kuiper belt family members are pluto, makemake , haumen, lxion, quaoar etc. 3.the ices in the kuiper be lt data back to the formation of sol ar system .   There have been more than a thousand objects discovered in the Kuiper Belt, and it’s theorized that there are as many as 100,000 objects larger than 100 km in diameter. Given to their small size and extreme distance from Earth, the chemical mak
