KUIPER BELT


INTRODUCTION



kuiper belt is an area of our solar system that is estimated to stretch across 20 AU of space.it is contains small asteroid and some big asteroid size of Pluto.this things made mostly of ice and other gases such as ammonia,nitrogen,methane and water.

the kuiper belt extends from roughly the orbit of neptune at 30AU to 55AU from sun.the main objects of this belt covers much of this region. 

FACTS ABOUT THE KUIPER BELT


1.there could be more than a trillion comet nuclei 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 belt data back to the formation of solar 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 makeup of KBOs is very difficult to determine.

However, spectrographic studies conducted of the region since its discovery have generally indicated that its members are primarily composed of ices: a mixture of light hydrocarbons (such as methane), ammonia, and water ice – a composition they share with comets. Initial studies also confirmed a broad range of colors among KBOs, ranging from neutral grey to deep red.

WHAT HAPPENED DURING FIRST SECOND OF BIG BANG??

FIRST SECOND OF BIG BANG           At 1 x 10 -43  seconds,            the universe was incredibly small, dense and hot. This homogeneous area of the universe spanned a region of only  3.9 x 10 -34  inches. During this phase, big bang theorists believe, matter and energy were inseparable.The four primary forces of the universe were also a united force.at that time  The temperature of this universe was 1 x 10 32  degrees Kelvin.the quark particles was made during this phase.   At 1 x 10 -35  seconds,           as universe expanded,its cooled and energy and matter decoupled. the universe filled with a nearly equal amount of matter and anti-matter. There was more matter than anti-matter, so while most particles and anti-particles annihilated each other, some particles survived. These particles would later combine to form all the matter in the universe.so...

ELECTROMAGNETIC FIELD OF EARTH INTRODUCTION                      The motions of the liquid iron and nickel outer core of the earth are thought to create the earth’s magnetic field. This magnetic field resembles a dipole as if a giant bar magnet was embedded inside. However, the axis of the dipole is not aligned with the rotational axis of the earth. Neither is it centered in the earth. EARTH'S MAGNETIC FIELDS PROTECT US FROM SOLAR WIND AND SPACE RADIATION.            The Sun is a burning ball of gas that reaches such extreme temperatures that gas flies out from it at very high speeds. In fact, many of the electrons in the Sun’s atoms have enough energy to actually leave the atoms. The abandoned charged atoms are called ions. These ions and electrons flow outward from the Sun, and together they are known as the solar wind.           When the solar wind travels with...

OUR NEIGHBOR,ANDROMEDA GALAXY

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.                Rec...
