A wormhole(or Einstein–Rosen bridge or Einstein–Rosen wormhole) is a speculative structure linking disparate points in spacetime, and is based on a special solution of the Einstein field equations.

A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, or different points in time, or both).

Wormholes are consistent with the general theory of relativity by Einstein, but whether wormholes actually exist remains to be seen. Many scientists postulate that wormholes are merely projections of a fourth spatial dimension, analogous to how a two-dimensional (2D) being could experience only part of a three-dimensional (3D) object.

A wormhole could connect extremely long distances such as a billion light years or more, short distances such as a few meters, different universes, or different points in time.

Kepler-22b, also known by its Kepler object of interest designation KOI-087.01, is an extrasolar planet orbiting within the habitable zone of the Sun-like star Kepler-22. It is located about 620 light-years (190 pc) from Earth in the constellation of Cygnus. It was discovered by NASA's Kepler Space Telescope in December 2011 and was the first known transiting planet to orbit within the habitable zone of a Sun-like star, where liquid water could exist on the planet's surface. Kepler-22 is too dim to be seen with the naked eye.

Do you know ?

Mars is named for the ancient Roman god of war. The Greeks called the planet Ares (pronounced Air-EEZ). The Romans and Greeks associated the planet with war because its color resembles the color of blood.

Mars has two small moons. Their names are Phobos (FOE-bohs) and Deimos (DEE-mohs). They are named for the sons of Ares, the Greek god of war. Phobos means “fear,” and Deimos means “panic.”

​​The average spacesuit in use today weighs approximately about 128 Kg.
In other words, it could actually be heavier than the astronaut himself, by as much as two times. The suit has around 11 layers of material to give its thickness and weight. It is made up of complex strength compound materials.
At the same time, however, it is not really much of a problem when you are in space. Given that there is almost no gravity, the weight of the space-suit is not going to mean much when you are up there.

​​Are you interested in alien life?
If you are interested then there is an observatory that you will find to be very fascinating. It is called the Arecibo Observatory.
It is located in a municipality called Arecibo in Puerto Rico and is one of the largest radio telescopes in the world. The first message from the observatory was sent in 1974 to contact aliens.
In very simple words, its goal is to seek out any signs of alien life in other parts of the universe.
