Scientific Fact #32

1....NASA's Deep Space Network (DSN) is a collection of antennas at three sites around the globe used to communicate with interplanetary spacecraft missions
DSN also is used by radio and radar astronomers to observe the Solar System and the Universe.
2.....There are three deep-space such communications facilities placed approximately 120 degrees apart around the world:

• at Goldstone, in California's Mojave Desert
• near Madrid, Spain
• near Canberra, Australia 

3.....The antennas on Earth must be able to track at very precise rates — at thousandths of a degree per second — to remain pointed at the spacecraft as the Earth is rotating at 0.004 degrees per second 

Scientific fact #29

1..Saturn’s rings are made up of particles of ice, dust and rock. Some particles are as small as grains of sand while others are much larger than skyscraper
 2..Jupiter is larger than 1,000 Earths.
There is a super massive black hole right in the middle of the Milky Way galaxy that is 4 million times the mass of the Sun.
3..The most dangerous asteroids, those capable of causing major regional or global disasters, usually impact the Earth only once every 100,000 years on average.
4..Some large asteroids even have their own moon.
5..Each day, Earth accumulate 10 to 100 tons of material.
6..There are over 100 billion galaxies in the universe.
7.. The largest galaxies contain nearly 400 billion stars.
8..Light reflecting off the moon takes 1.2822 seconds to reach Earth.

9..The International Space Station orbits at 248 miles above the Earth
10..The nearest known black hole is 1,600 light years (10 quadrillion miles/16 quadrillion kilometers) away.
11..The Moon is moving away from the Earth at about 34cm per year.
12..If you travel with the speed of light,then you could go around the earth 7 times in just 1 second

Scientific Fact #2

Due to tidal the speed of earth decrease by 1cm/year,this energy loss due to tidal

Scientific Fact #1

A black hole is very high density material,when earth compressed like a cricket ball,then it behave as black hole
