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...
How Long Could You Survive In Other Planets of Solar System ?

How Long Could You Survive In Other Planets of Solar System ?

Earth is a beautiful place. You will surely start appreciate a lot more when you find out how long you will survive through other places of the Solar System. Without any protection, of course! And let me give you a clue: There is no place in the Solar System other than Earth, which you can survive longer than two minutes. Let’s start from the Sun. Will evaporate instantly. “Although I’ve heard that if you visit at night …” joked Niyl Degras Tyson …. LOL ( Check the Video bellow ) Mercury – no more than two minutes as long as...
Laniakea – The Name of Our Home Supercluster

Laniakea – The Name of Our Home Supercluster

  Group of astronomers have discovered that our own Milky Way galaxy inhabits the outskirts of unknown, until now, massive galactic supercluster, reports the Nature magazine. They named it Laniakea that comes from Hawaiian and means “immeasurable paradise”. (watch the video bellow) The discovery was made with the help of a new mapping technique that combines not only the distance between neighboring galaxies, but their relative motions. The technique has allowed astronomers for the first time to clearly delineate exactly where one supercluster of galaxies ends and where another begins. The new map shows that the Milky Way  among with the...
10 Interesting Moon Facts

10 Interesting Moon Facts

    The moon always acts hypnotically no matter in which phase is. The beauty that lives at night has inspired not only one romantic soul. Although we see it quite often almost never think about its nature. Here are some interesting facts about it: Lunar dust. One of the most bizarre yet dangerous substances on the moon is the lunar dust. It is fine like flour, but very rough, so permeates almost everywhere. Lunar dust creates a lot of headaches during missions: dust almost completely cut the shoe of an astronaut, penetrates the ships and spacesuits, causing ‘lunar hay...
How Big is Sun compared to Earth?

How Big is Sun compared to Earth?

  The Sun! Our everything. The source of Life and at the same time an ordinary Star in an ordinary Galaxy. But how big is actually? The most easy way to understand the size of the Sun is to compare it  to something we know. Our home Planet – The Earth will do a wonderful job. But first let’s look up a bit of digits. The Sun is a star at the center of the solar system. It represents almost a perfect sphere made up of hot plasma and magnetic fields. Its diameter is about 1 392 000 km, nearly...
What is Gravity?

What is Gravity?

We all know what is Gravity – it is what keeps us down to Earth. It is the thing that makes apple to fall next to the tree. But what is the definition of Gravity in physics?  It’s one of the fundamental interactions in the Universe. Fundamental interactions in physics are four completely different in nature interactions between elementary particles and bodies that they build. Many efforts in modern physics are focused at finding a common unified theory that would unite all interactions. So far, such a theory is not found. Here they are: Gravitational interaction Electromagnetic interaction Strong nuclear...
Speed Of Light

Speed Of Light

      Perhaps all you have heard at least once the expression “Speed of Light”. If you are from those who know that this is something very fast but  do not know how much actually, I will say that it’s about 300000 km/sec or  670,616,629 mph (miles per hour) and that is the speed of the photon – the only particle with no mass, and will add that there is nothing faster than it. In fact, because we see thanks to photons that pass through our eyes,  if their speed was much more slower we would see everything around behindhand. It sounds...
