Why Finding Life on Other Planets is so Hard?

Why Finding Life on Other Planets is so Hard?

The perfect combination of enough land and water turns out to be rarity in the Universe. According to scientists at the University of Barcelona, it is quite difficult to find a planet that has conditions suitable for life and not completely covered by water, Engadget reported. A total of 29% of the Earth’s surface is land. According to the computer model of scientists, however, this is rather an exception. On most of the planets that have enough water, the land is less than 10% or none at all. The planets with more land, however, do not have enough water to...
What is a Black Hole?

What is a Black Hole?

  A black hole is a region of space-time that can not be left from anything, even light. The general theory of relativity provides that a compact enough mass could distort space-time to such an extent that a black hole is formed. Around the black hole is formed mathematically determinable surface, called the event horizons, that marks the point at which the return is impossible. Want to learn more about it?

What is the Closest Star to Earth?

What is the Closest Star to Earth?

  Alpha of Centauri is a special Star – not only because it is closest to our solar system, but it is also one of the places in the Milky Way where life may exist. If people are looking for intelligent life outside our Solar System, Alpha of Centauri is an excellent candidate. The Alpha of Centauri is located at a distance of 4.35 light-years from us. In fact, it is a triple star system. The two bright components, Alpha Centauri A and B, form a pair. They travel about each other for 80 years at a distance of 23...
What is Space Travel?

What is Space Travel?

Scientists have been looking from long time for safely travel to space. The main problems for the realization of this idea are related to long distances and the fact that the human organism may not resist such a journey. For example, the distance between Earth and Mars is about 55 million kilometers, and months are needed to get to the “red” planet. “Innovative Advanced Concepts” is an innovative NASA program that offers solutions to these issues. Their concept envisages the construction of a special cabin in which human can travel safely to Mars for several months. The module will have...
Why There is still no Evidence of Extraterrestrial Life?

Why There is still no Evidence of Extraterrestrial Life?

  The Milky Way is home to billions of Stars (100 to 400 billion). Each of them is potentially the center of a system of Planets. In the visible part of the Universe there are at least 2 trillion galaxies similar to ours. And it is full of Planets – trillions in the orbit of billions of Stars. Even assuming that the chances any of these Planets to have life are minimal, pure statistic suggests that somewhere there must be intelligent Life. If only 0.1% of the Planets in our Galaxy could be habitable, it means that it will have...
