Extremely rare cosmic object has just been discovered in the Milky Way
The object, known as MAXI J1816-195, is located no more than 30,000 light-years from Earth. According to a database compiled by astronomer Alessandro Patruno, preliminary observations and investigations suggest that it is a pulsar (or pulsar) - inherently fast-rotating neutron stars with a charged beam of X-rays. capacitor. Previously, only 18 other pulsars were observed.

It is known that the light from the X-ray beam emitted by this object was first detected on June 7 by the Japan Space Agency's sky X-ray imaging (MAXI) instrument, mounted at outside the International Space Station ISS.
Immediately, a team of astrophysicists led by Dr. Hitoshi Negoro of Nihon University in Japan has announced that they have identified a previously unknown source of X-rays, located in the galactic plane between the constellations Sagittarius, Cancer, and Scorpio.
Using the Neutron Star Component Analyzer (NICER for short), a NASA-provided X-ray instrument, the researchers obtained X-ray pulses at a frequency of 528.6 Hz, shows that the object is rotating at 528.6 times per second - the same frequency as an X-ray fusion explosion.
This discovery shows that MAXI J1816-195 is exactly a new X-ray pulsar, and astrophysicists are extremely excited about this.
At a very basic level, a pulsar can be understood as a type of neutron star, with its core being formed by the collapse of a massive star, and then turning into a supernova. The objects in common are so small but dense, that they can have a mass about 2.2 times that of the Sun, but only have a diameter of about 20km.
To be classified as a pulsar, a neutron star must of course. emit pulsations, or in other words these are beams of radiation emitted from the star's poles. Because they are often tilted, these beams sweep across the Earth like beams of light coming from a lighthouse, only they are very fast, at speeds up to hundreds of times per second.
Due to the extremely limited number of previously known pulsars, any new objects as they emerge are considered a novel discovery, and could yield important information about how objects are formed, developed, and operated.
