The discovery of the solar system ?

Who is the solar system?

In the Solar System, the Sun and many planets, astronomical objects are inserted, and all these celestial objects are bound by the gravitational force of each other in the Solar System. 

Some orbits revolve around, the group of objects of these celestial bodies called the planetary system Which does not have other stars, such as asteroids, dwarf planets, natural satellites, asteroids, meteors, comets, and celestial dust. Our solar system is formed by combining our sun and its planetary bodies. 

These celestial bodies include eight planets, their 166 known satellites, five dwarf planets and billions of small bodies.Except for some notable exceptions, it took thousands of years for humanity to know the existence of a solar system.                                                                   
Before exploring the solar system.

Before the discovery of the Solar System, humanity's thinking was somewhat different.People first thought that the Earth is the center of the universe and is clearly different from the divine or northwestern objects roaming in the sky. But in 140 st Claudius Toulmy said (according to the Jeocentric concept) that the earth is in the center of the universe and all the house objects revolve around it.

Solar system search.

Nicholas was the first European astronomer who considered the Earth to be outside the center of the Universe, that is, to apply the Heilosentrism model. Earlier, the entire Europe believed in Aristotle's concept, in which the earth was the center of the universe, and the Sun, the stars, and other bodies revolted around it.

Copernicus' book, De Revolutionibus, was published in 1530, in which he said that the earth revolves around its axis and completes the revolution in one day and completes the Sun's journey in one year. Copernicus composed protopic tables to find the position of stars which became quite popular among other astronomers.

In the 17th century, Galileo Galilei, and Johannes Kepler address pressed that the earth revolves around the sun after the invention of the telescope began to search for planets and moons and around 1704, "Solar System" word was first published in English was done.

Galileo Galilei discovered before the physical details of the solar system and they know were found in orbit four satellites around Jupiter and Galileo Galilei discovered the Christian Hujens discovered four of Saturn's moon Titan and Saturn, the rings and in Giovanni Domenico Cassini was discovered four satellites of Saturn and Sun in search of Binary Stars in 1781 when he saw a new comet. Its class showed that it was a new planet, Uranus.And thus our solar system was discovered.

NASA's Spitzer Space Telescope will be closed.

NASA briefly informed that the Spitzer Space Telescope will be permanently discontinued on January 30, 2020. After about 16 years of discovering the universe in light energy.  And by that time, the space shuttle has been working for more than 11 years beyond its prime mission, Spitzer examines the universe's various objects in infrared light.  It was in 2003 through the rocket that the American Space Research Organization NASA entered the space and entered the orbit around the Earth.  Spitzer rotates the sun on a path similar to that of the Earth but it runs a bit slower.  Today it is about 158 ​​million miles (254 million kilometers) away from our planet - more than 600 times the distance between Earth and Moon.  The spacing of Spitzer's orbit curve means that when the spacecraft indicates its fixed antenna on the earth to download data or receive commands, its solar panels tend to lean away from the sun.  During those periods, to operate the space shuttle, one should rely on…

SpaceX is launching its next dragon spacecraft.

SpaceX is preparing for its next mission, very soon Spacex will launch the Dragon Spacecraft with its Falcon 9 Rocket.
  SpaceX is the 18th commercial reproduction service mission, dragon spacecraft will be loaded with dozens of experiments made in space.  Launch date: Sunday, July 21, 2019 at 7:35 pm  International Space Station (ISS) us  The National Laboratory SpaceX's dragon is giving a finalization to more than two dozen payloads for launch in a circular circular laboratory.  Many of these payloads are aimed at improving human health on the earth, many of which are focused on drug development.  In addition, a series of payloads from identified private sector partners will be launched on this mission.  More than 40 student experiments and demonstrations have been included on the 18th Commercial Recepti Services Mission (CRS-18) of SpaceX.  One part of ISS American National Laboratory's goal is to encourage and engage next generation scientists.                              …

SpaceX,Dragon Cargo Returns Mission in Pacific ends with SplashDown

SpaceX dragon cargo spaceship dropped at 5:48 pm in the Pacific Ocean.  The EDT (2:48 p.m. PDT) is located approximately 202 miles southwest of Long Beach, California, which is located at the end of the company's 17th contracted Cargo Resipulli mission for NASA.  Spacecraft returned more than 4,200 pounds for other valuable scientific uses. Some scientific investigations of Dragon's return to Earth include: Overview of protein crystals growth, in the use of NASA's biophysics-6, to be interested in cancer treatment and radiation safety  There has been an increase in the growth of two proteins.  Scientists are using ground-based predictions and X-ray crystallography in space to determine that proteins are beneficial in crystallization in microbiology, where some proteins can grow with big and small flaws.Microglio biosynthesis in M…
