This is an aerospace telescope dedicated to capturing X-ray signals. It weighs about 5 tons and carries an orbit more than 50 thousand kilometers from the ground. On September 19, June 24, NASA announced that the Space Telescope captured a very special X-ray signal from the depths of the Galaxy, which made Astronomy very excited.

Generally, a planet does not emit X-rays. Where is the magical X-ray signal from? What does it mean? Scientists say this is a high-energy ray emitted by the neutral (Neutrino) during the Decay (Decay), which exists in the so-called "Dark matter" ("Dark matter. Scientists think that black and dark matter occupy 85% of the total amount of material in the universe, and such a substance does not emit light, but does not absorb light.

It is also translated as a microneutron, a kind of light sub, and one of the most important particles in the natural world. The neutron is not charged, the spin is 1/2, the mass is very light, less than one of the millions of electrons, moving close to the speed of light. The neutron is not electrified and can freely pass through the Earth. It almost does not act with any matter. It is called the "invisible man" in the universe ". It took more than a decade for scientists to predict its existence and discover it.
