Impact Craters

When a Metorite collides with Earth it can form an impact crater – a bowl – shaped hollow in the Earth’s surface. Space rocks have produced in this way throughout Earth’s life, especially when the planet was young, about 4 billion years ago.

Space rocks do not have to hit Earth to have a devastating effect. On june 30, 1908, there was an explosion 3.5 miles up in Earth’s atmosphere, above the unpopulated Tunguska River region of Siberia. It was caused by the disintegration of a small piece of comet or asteroid. The blast uprooted trees in a 12-mile area and was heard up to 600 miles away.

The manifestation of the red monster is from yellow orange to red, incorporating the unearth...
Explaining Gravitational Lensing
Light always leaves from a young, star forming blue galaxy near the edge of the visible universe. Some of the light passes through a large cluster of galaxies and surrounding dark matter, directly in the line of sight between earth and the distant galaxy. The dark matter’s gravity acts like a lens, bending the incoming light.  
Interplanetary Travel
The planets are very far away. A spacecraft traveling at 60 mph a typical speed of a car on a highway – would take about 60 years to reach Mars. Fortunately, rockets travel much faster than this. The Voyager spacecraft sped from the Earth at 32000 MPH. But even at this speed, travel to the planets takes a long time. The Future space colonies will have to be self – sufficient, growing t...

A decade of intense space activity followed as Russian and American probes, robots, and crewed craft were sent to investigate and land on the l...

Stellar advancement is the methodology by which a star experiences an arrangement of radical updates around its lifetime.

All stars are born from falling mists of...
Lunar Eclipses Explained
A eclipse occurs when the Moon passes straight at the rear of the Earth into its umbra (shadow). This will happen only once the sun's rays, Earth, and Celestial satellite are aligned specifically, or extremely closely thus, using the World in the middle. Therefore, the eclipse can only occur the night time of your full-of-the-moon. The sort and also period of a great eclipse depend upon the Mo...
What is it Like Inside a Black Hole
Black holes are prisons of Light, where gravity is so strong that nothing can escape. But they have even more bizarre effects: a block hole’s gravity distorts space and time, and the laws of physics break down at its center.
