Most recently, scientists have discovered the largest cold spot in the universe. It is located in the southern part of Eridanus constellation. Its length is 1.8 billion light-years.
Despite the presence of the word «void» in the name, the space is not completely empty. In this region of space approximately by 30% less the cluster of galaxies than in the surrounding space are located. According to scientists, entering up to 50% of the universe, and this percentage, according to their own opinion, will continue to grow thanks to the super strong gravity that attracts substance surrounding them.
In 2006, the title of the largest objects in the universe was taken by a mysterious space "bubble". This bubble length of 200 million light years is a huge cluster of gas, dust and galaxies. It looks like a giant green jellyfish. Japanese astronomers have discovered the object while studying one of the regions of cosmos, known by presence of a large amount of cosmic gas.
Shapley supercluster, a supermassive galaxy cluster, located behind the Great Attractor, an object with a force of gravity, which is already enough to attract the entire galaxy. It is so huge and has so powerful attraction that attracts Attractor itself, and its own galaxy. Supercluster consists of more than 8,000 galaxies with a mass of 10 million Suns.
The Great Wall CfA2 was opened by American astrophysicist Joan Margaret Geller and John Peter Huchra while studying the effect of red shift for the Harvard-Smithsonian Center for Astrophysics. According to scientists, its length is 500 million light-years, and the width of 16 million light-years. It resembles the Great Wall of China by its form. Hence it received such nickname.
A new way of mapping the local area was recently invented. The new principle of mapping the local space and galaxies is based not only on the calculation of the physical location of the object, but on measuring the gravitational influence exerted by them. With the new method determines the location of galaxies, and based on this mapping the distribution of gravity in the Universe. The new method is more advanced because it allows astronomers not only point out the new objects in the universe, but also to find new objects in places where previously it was not possible to look.
