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...
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...
Can You Cry in Space?

Can You Cry in Space?

Of course you can! But is it a good idea? If one day you can get on the International Space Station, for example, or just go into orbit around the Earth and fall into weightlessness, you will probably want to shed at least one tear of emotion. You’d better not! Why? Canadian astronaut Chris Hadfield shows why. True, his “tear” is a bit more generous than usual, but, as you can see, the tears are not willing to leave you in space. They stay with you. They do not really want to go! At least until you find enough dry...
The Most Powerful Solar Eruption in The Last 12 Years

The Most Powerful Solar Eruption in The Last 12 Years

NASA experts have registered one of the most powerful solar eruptions in the last 12 years, which is one of the 15 most powerful emanations of light, heat and kinetic energy in the entire Sun observation history. NASA reported that the power of the eruption was so great that residents of Ohio and Indiana would be able to observe the northern lights that night. Solar eruptions are often accompanied by similar phenomena. But today a full moon is expected, and the Earth’s natural fellow traveller will slightly dim the brightness of the glow. Solar eruptions are the cause of magnetic...
September 3, 1976 – Viking 2 Landed on Mars

September 3, 1976 – Viking 2 Landed on Mars

On September 3, 1976 on Mars landed the Viking 2 – a drop-off module, which sent the first close color photographs from the surface of the Red Planet. NASA’s Viking program is the first space program to send spacecraft to Mars. Viking 1 and Viking 2 were launched in 1975 and 1976. They were created precisely for the detailed study of Mars. Each of the spacecraft is composed of two modules: one that is in orbit around the planet, and another that descends to the surface. The program is one of the most ambitious for its time, and its value...
What is Coming Up at The August Night Sky

What is Coming Up at The August Night Sky

  Total Sun Eclipse August seems quite full of astronomical events, and the Great American eclipse on 21st is far from being the only remarkable thing to come. The upcoming total solar eclipse is the first to be seen from the continental United States since 1979, and the first seen from coast to coast since 1918. Partial Lunar Eclipse This month, some lucky viewers will be able to watch as the moon skirts through the northern part of Earth’s dark outer shadow, producing a partial lunar eclipse. While most of Europe and Africa will get to see part of the...
