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?

Is it Different The Taste of Food in Space?

Is it Different The Taste of Food in Space?

  Canadian astronaut Chris Hadfield tells how our taste perceptions change when we get into zero gravity. When we get into space, the food really does not have the taste we’re used to. And the reason is not in the food itself, but in the way our body functions. It’s used to fighting gravity and pushing more blood to the head than it needs: “Your head kind of inflates as if somebody squeezes the end of a balloon,” says Hadfield. Without the gravity to draws the liquids down, the sinuses are clogged and you feel almost no taste. This goes...
Scientists Have Discovered the Cause of Solar Eruptions

Scientists Have Discovered the Cause of Solar Eruptions

For centuries, scientists have been puzzled by the gigantic and unpredictable outflows of plasma from the Sun, sometimes so aggressive that they can cause the glow of the Earth and disturb communications on our planet. But an international team of scientists think they may have finally identified the mechanisms that trigger these eruptions, and unlike previous theories, and small and large solar flares are caused by the same dramatic process. If the new hypothesis is correct, scientists may be able to predict eruptions, but also and when will cause damage on Earth. The researchers analyzed 3D simulations of two main...
The Solar System

The Solar System

We are convinced that you know a lot about the planets of the Solar System and we can hardly tell you something you have not heard before, but still, in order to be a real website, and for our heading to be complete, we need to pay attention to this topic. And secretly we hope you will still learn something new from us. So let’s start … The Solar System is a group of astronomical objects including the Sun and all the objects of orbit around it – asteroids, comets, planets, dwarf planets, satellites, interplanetary dust and gas. All of...
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...
Astronomy For Everyone

Astronomy For Everyone

Today, we are living in an unprecedented times in which every well-motivated resident of the World can do amazing things – for example, to search for exoplanets or to make other serious astronomical discoveries. Here are some websites that can be a starting point for every lover of Astronomy: http://www.worldwidetelescope.org The Worldwide Telescope (WWT) is exactly what its name implies. This multimedia application is a great illustration of the extent to which the World Wide Web has democratized science. WWT unites astronomical information from many sources, including some of the largest terrestrial (like Palomar in the US) or space telescopes...
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...
