Astronomers baffled to find cosmic mountain range in the Milky Way

Scientists have no idea how these cosmic structures formed. In a recent discovery, scientists found a cosmic mountain range in the Milky Way.

cosmic mountain range in the Milky Way

For us, the night sky looks like a blanket full of scattered stars, but astronomers are learning that in some regions of our galaxy the stars gather in such a way that they create characteristics similar to those here on Earth: currents, waves, arcs and mountains

Tectonic activity is responsible for creating depressions and mountains in our world, but when we speak at the cosmic level, astronomers do not know how stars are capable of — honoring a hermetic principle — imitating such formations. Now, researchers are formulating theories about it, including forces from outside our galaxy. Although, they speculate, the reason for this mysterious topography could be found in the Milky Way itself.

A team led by astronomers from the University of Sydney, Australia, analyzed data from the Gaia mission of the European Space Agency, which made a kind of galactic census cataloging about 1 billion stars with their respective positions and distances. In particular, the researchers focused on a series of eight “crests” of the Milky Way that are distributed forming a “cosmic mountain range.”

They discovered that these ridges are stacked in the middle layer of the galactic disk and that each one has a collection of unique stars studding its tops. By taking data from another mission that studied the composition of the stars, they realized that they all had compositions similar to that of our sun. And since an elementary composition can signal a stellar age, this indicated to them that these young stars were not scattered in the same ways as the older ones, which helps to understand how the mountain ridges formed.

So far the authors of the study handle two theories. The first says that the internal mechanisms of the galaxy are the key to its geography and shape. For example, gravitational interactions that generate resonant waves that at the same time create large groups of matter. Alternatively, friction between stars, gases and galactic dust can lead to the birth of these topographic characteristics, in the same way that garments in the washing machine become entangled during the washing process. The second theory proposes that there is an external force, such as a dwarf galaxy, that stacks the stars.

Likewise, in the computer simulations it was observed that in the latter case, that of the external force, more pronounced peaks were given. “So the height of the ridges could be a way to discriminate between the performance of internal and external processes,” said Shourya Khanna, lead author of the study .

Future surveys of Gaia on stars still uncatalogued could provide astronomers with more clues about the forces that draw the amazing geography of our galaxy.

NASA published pictures of two giant asteroids

NASA published an amazing image of two giant asteroids traveling in the asteroid belt, both of which are larger than some of the cities in the world.

The American Space Agency shared a snapshot that tracks the movement of the large asteroids Lina and Klotho, located in the asteroid belt between Mars and Jupiter. The Lina is about 37 miles (60 km) in diameter and has more than 2,000 days in orbit around the Sun. Klotho is slightly larger, having 50.9 miles (82 km) in diameter and has a 1596-day orbit around our main star.

NASA observed space rocks using the NEOWISE telescope. He also states on his official website:

“appearing as rows of orange dots, the brightest sets of dots belong to the asteroids of Klotho and Lina. Both rotate in the main asteroid belt between Mars and Jupiter, while smaller and more distant asteroids can also be seen on this image ”

These space objects were photographed by NEOWISE as part of the Wise mission (Wide-field Infrared Survey Explorer) asteroid hunting project. 

Cosmic stones within the asteroid belt supposedly pose almost no danger to the Earth, due to the role that Jupiter plays in the solar system. The giant planet has such a powerful gravitational attraction that it actually helps to keep the asteroid belt in place, so objects do not travel throughout the system.

If Jupiter did not use its gravitational pull on these objects in the belt, the inner planets would be constantly at risk of collisions with large asteroids.

“The presence of Jupiter actually protects Mercury, Venus, Earth, and Mars from repeated collisions with asteroids!”, The NASA statement said.

The probability of a major asteroid colliding with the Earth is one in 300,000 chance. However, such a prospect is possible, NASA says.

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.
