Sednoids

It is easy to understand what a sednoid is. A sednoid is a trans-Neptunian object. Its perihelion exceeds 50 AU from the Sun, that is, farther than Neptune. These objects form a lot of sub-objects (they are divided into many pieces). The sednoid is "an object of Oort's cloud." This explanation started with Chadwick A. Trujillo and Scott S....

Space winds

The space wind is actually the solar wind. The solar wind is an emission of electrically charged particles from the Sun. And the fact that the flow of particles is electrically charged, means that the solar wind is largely made up of protons and electrons. Usually the flow comes with a load of approx. 1.5-10 keV. (electronvolts), But we can...

Cosmic dust

Cosmic dust can also be called Interplanetary matter is a dust made up of several molecules and atoms, for example: 0.1 mm molecules. It exists between any two bodies in space. What we see as black in space is not a vacuum, it is just cosmic dust but divided into billions of pieces, so it is not seen. It...

Nebulae

As you can see a nebula is very colorful. Many confuse the nebula with the northern lights, but it's not the same! The nebula can form the birth of a star, but this happens when the nebula is large, dense and can form several at once. But there are also nebulae that cannot form stars because they are not...
