The most powerful magnet in the universe, with a truly colossal level of radiation, Magnetar!

Perhaps you think the universe is ideal for life. However, it is not. Almost the entire Universe is a terrible and hostile place, and we were just lucky to be born on an almost harmless planet in a remote region of the Milky Way.

Here on Earth you can live a long and happy life, but in the Universe there are places where you will not last even a couple of seconds. Nothing is more deadly than objects that supernovae leave behind: neutron stars.

However, approximately one in ten neutron stars becomes something really very strange. It becomes a magnetar – the most mysterious and terrible object in the universe. You’ve probably heard the word, but what is it?

Over the past 50 years, mankind has come across several times with phenomenal radiation coming from outer space. As often happens, astrophysicists could not immediately identify the source.

1979 year. Three American Vella satellites monitoring nuclear tests on Earth record an unusual gamma-ray burst.

1992 year. Astrophysicists suggest the existence of a celestial body unknown to science with a huge coefficient of electromagnetic radiation.

1998 year. The outbreak in the constellation ” Eagle “. Many measuring instruments record an inexplicable anomaly, the source of which is located tens of thousands of light years from us.

2004 year. All world telescopes are temporarily blinded. In less than a second, a wave of gamma radiation passes through every square centimeter in the solar system . The largest outbreak in the history of observations.

Today we are as close as possible to finally explain the nature of this discovery.

Magnetar or Magnitar  is a poorly studied neutrona star with an exceptionally strong magnetic field of about 10 to the 13th degree of Tesla . Almost a trillion times more electromagnetic radiation from the Earth .

When the lifetime of a supermassive star comes to an end, a supernova explosion occurs and among the many options for events there is only one in which the star can become a Magnitar. The disputes of scientists that this option represents do not stop to this day.

The diameter of Magnetars reaches only 20-30 km. For comparison, the diameter of the moon is 3474 km, that is, about 173 times more than the average Magnitar . However, with the mass, everything is arranged a little differently. Magnitar with a radius of 15 km, despite its size, will be heavier than our Sun, a radius of 696,340 km.

Theoretically, if Magnitar would be within the limits of the Solar system , we would not have time to notice the threat. The ozone layer of the Earth, along with all forms of organic life, would be wiped out within seconds.

Fortunately, the closest to us Magnitar is at a fairly safe distance from us, 12,000 light-years.

A “Meteorite” falls in Nigeria destroying more than 100 houses and leaving a huge crater

On the morning of Saturday 28 March 2020, a large meteorite crashed in Akure (Nigeria), destroying more than 100 houses and leaving a 21-meter crater on the ground. Experts from the Awbaowo University of Obafemi (Nigeria) denied the local police who initially claimed that a bomb explosion had created the 21-meter crater.

According to Nigerian sources, the explosion destroyed the Akure-OVO road and seriously damaged dozens of houses, from 50 to 100, as well as schools and churches.

It is interesting that initially the authorities denied the meteorite’s fall and claimed that the cause for the explosion was a truck with explosives, which was transported to a neighboring state. Ondo State Governor Rotimi Akeredolu said the blast was an accident.

Then the version changed and the truck was no longer just transporting explosives, but it was supposedly a terrorist act.

Now, a team of experts and scientists came to the conclusion that everything that happened was a fall of a large meteorite.

The blast that shook Akure, the state capital of Ondo, on Saturday, was caused by a giant cosmic rock, a team of experts concluded.

Led by Adepelumi Adekunle, a professor of geophysics and seismic engineering at Obafemi Avolovo University, the team said that the meteorite entered the atmosphere of our planet at a “43 degree angle”.

Adepelumi Adekunle’s report reads:

“My research team conducted a detailed analysis of the impact site. A round impact crater was discovered with a diameter of 21 m and a depth of 7.8 m, which indicates a natural phenomenon.

– It was found that water is oozing from the edges of the crater. Preliminary field studies of vibration, noise, seismicity, analysis of water, radioactivity, rocks and soil were carried out.

“Our findings suggest that the impact of the explosion covers a radius of 1 km from the vicinity of the crater.” No signs of fire or burning were found in the vicinity. “

“No signs of radioactive radiation were found within the crater and in the immediate vicinity of it. Field data indicate that a meteorite from the asteroid belt was moving at high speed from space, and fell at an angle of 43 degrees in the southwestern part of the country “

A local source said that after the incident, no one was missing and no one was killed. The most interesting thing in the report is the mention that “unusual stones and strange metal objects” were found inside the crater. So what actually fell in Nigeria – a meteorite or a UFO?

Something strange is happening with the interstellar comet 2I / Borisov

When astronomers see something in the Universe that at first glance seems to be one of a kind, this will certainly cause great excitement and attention.

This mysterious guest from the depths of space first attracted the attention of celestial observers at the end of August 2019, when it was officially discovered sweeping through the solar system along a trajectory indicating interstellar origin.

After analyzing the object, astronomers identified it as a comet called Comet 21 / Borisov, which is the first identified comet and the second observable interstellar alien after the infamous Oumuamua, who arrived here from another star.

NASA claims that they do not know where and when the comet began to move towards our Sun. Gravity of the Sun slightly deflects its trajectory, but cannot capture it due to the shape of the orbit and its high speed of about 160,934 km / h.

Hubble showed that the comet’s heart, a loose accumulation of ice and dust particles, was probably no more than 975 meters across, about the length of nine football fields.

Now, this month, astronomers have discovered that something strange is happening by checking the object.

In the next video, nemesis maturity explains what happens to this mysterious interstellar guest.

Hundreds of exoplanets with two suns discovered

Until recently, in search of inhabited exoplanets, binary star systems were completely undeservedly ignored. Exoplanets with two suns have long become familiar places where the events of science fiction novels and films are unfolding.

One of the most striking and well-known examples of this is the desert planet Tatooine, the birthplace of Anakin and Luke Skywalker in the famous Star Wars movie saga. But only in 2011, NASA scientists using the Kepler space telescope were able to provide clear evidence that such exoplanets that revolve around two stars at once really exist. The planet discovered then was called Kepler-16b.

Despite the impressive discovery, scientists continued to believe that such planetary systems are extremely rare due to the complex attraction of two suns at once. But this opinion turned out to be completely wrong, writes astrophysicist Paul M. Sutter in an article for Space.com. This was revealed as a result of a new analysis of millions of stars and the discovery of exoplanets that have been recorded and cataloged by the ESA space telescope since 2013.

In fact, there are only two scenarios in which planets cope with the complex gravitational forces of two stars. If the stars are located very far apart, the planet can rotate around one star – then the other will be visible from the surface of the planet as a brightly shining star in the sky. In another case, both stars are close to each other – then the planet rotates at a safe distance around its double sun, as if it were just one celestial body.
These seemingly unbelievable stellar constellations are likely to occur much more often than might be expected.

Researchers have discovered during their targeted search already 300 exoplanets that could “boast” of double suns. Until now, astronomical science has actually ignored binary stars to search for (inhabited) exoplanets, because scientists considered their occurrence extremely unlikely in principle. In the case of discovered 300 planets, it is most likely a question of constellations, in which binary stars were incorrectly interpreted by the telescope as single stars.

Sutter speaks of decades of scientific confusion and uncertainty: “Since we did not often pay attention to the search for planets in binary solar systems, we had little chance of finding them. We didn’t look for anything like that, therefore we didn’t find it. The researcher believes that the realization that such double suns are very common should definitely be considered when searching for new exoplanets.
