The space is incredible!
Space is the boundless three-dimensional extent to which objects and events have relative position and direction. It is also filled with, magnetic fields, light, heat, and high-energy particles (e.g. cosmic rays).
- Cosmic rays => Cosmic rays are high-energy protons and atomic nuclei that move through space at nearly the speed of light. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments.
- Magnetic fields => A magnetic field is a vector field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.
What is Solar System?
The Solar System is the gravitationally bound system of the Sun and the objects that orbit it.
Who did go first in space?
On April 12 in 1961, Russian cosmonaut Yuri Gagarin (left, on the way to the launch pad) became the first human in space, making a 108-minute orbital flight in his Vostok 1 spacecraft.
First Animal in space.
The first animal to make an orbital spaceflight around the Earth was the dog Laika, aboard the Soviet spacecraft Sputnik 2 on 3 November 1957.
Vostok 1 was the first spaceflight of the Vostok program and the first human spaceflight in history.
Jump from Space !😱
Austrian skydiver Felix Baumgartner completed a parachute jump from a height of 38,969.4 meters, smashing through eight world records and the sound barrier in the space of just three hours.
What causes a falling star?
These amazing streaks of light you can sometimes see in the night sky are caused by tiny bits of dust and rock called meteoroids falling into the Earth’s atmosphere and burning up.
What are meteoroids?
A small body moving in the solar system would become a meteor if it entered the earth’s atmosphere. It is smaller rocks or particles in orbit around the Sun.
What are asteroids?
A large rocky body in space, in orbit around the Sun.
What is Satellite?
A satellite is a moon, planet, or machine that orbits a planet or star.
There are two types of the satellite:
- Natural Satellite: A natural satellite is any celestial(celestial body is any natural body outside of the Earth’s atmosphere) body in space that orbits around a larger body. Moons are called natural satellites because they orbit planets.
- Artificial Satellite: Artificial satellites are man-made objects that orbit the Earth and other planets in the Solar System. Soviet Sputnik 1 mission was the first artificial satellite that was launched in 1957.
