An unknown object — a “cosmic string” – has been discovered near the milky Way’s supermassive black hole. This cosmic thread will revolutionize our understanding of gravity, space-time, and the Universe itself.
The center of our Galaxy has been intensively studied for many years, but it still holds surprises for scientists. A snake-like structure lurking near our galaxy’s supermassive black hole has become a discovery that teases the imagination of astronomers. “A mystery that became part of the thrill. Science has stumbled upon a mystery that is not easy to solve,” said Jun — Hui Zhao of the Harvard-Smithsonian center for astrophysics in Cambridge, Massachusetts. “While we don’t have an answer yet, the path to finding it is fascinating.”
In 2016, Farhad Youssef-Zadeh of northwestern University reported the discovery of an unusual luminous filament near the center of the milky way galaxy using a very large NSL Karl j matrix. Yansky (VLA). The thread is about 2.3 light-years long and curves around and towards a supermassive black hole called Sagittarius A * (Sgr A *), located at the center of the Galaxy. Continue reading
Solar system. Planets of the solar system
Its center is a huge star called the Sun. It is the closest star that is billions of years gives us light and heat. Without it, impossible would be life on the planet. Around it revolve the planets, of which eight are known today, as well as other celestial objects.
Schematically, the structure of the solar system is as follows:
Man is always interested in the question thus arose our solar system. But it was a long time before scientists were able to answer this question. There were many versions and assumptions on this issue. And today, astronomers are continuing their investigation.
According to a hypothesis of Kant-Laplace five billion years ago there was only a gas cloud. It moved through the universe, but at some point he undergoes certain processes. Then there is compression and then begins the rotation, the center of rotation is the fastest. The temperature at the center of the cloud began to grow and formed a protostar that later became the Sun. The nebula continued to spin, and the star are unable to absorb all the substance of the nebula, they are attracted, experienced, forming planetesimal. One of them appeared on the planet.

Not so long ago such a statement would cause an uproar in any self-respecting astrophysicist and most likely, it ended in the usual enumeration of the several variants of the origin of our Solar system. Today, however, a number of researchers not only did not reject this version and think its main. What is the reason? We will try to understand.
It all started with sightings NASA space Observatory named “Kepler”. The satellite was launched in 2009, and in 2020 due to the loss of orientation in space failed. The Observatory was equipped with incredibly sensitive Photometer and specially designed to search for exoplanets, i.e. planets outside our Solar system like Earth. The ability of the apparatus to observe more than 100,000 stars at the same time very quickly gave the opportunity for scientists to get incredible data about other Solar systems.
In early 2010 the Observatory was discovered planetary system Kepler-33. The star Kepler-33, located in the constellation of Cygnus, was bigger than our Sun, and planets revolving around it, was very close to the parent star. Continue reading
