Source of Fermi Bubbles, A Black Hole Eruption According to Researchers

Published

on

A new study of scientists led to the development of a hypothesis about how the two huge bubbles in the center of the Milky Way emerged. According to the study, huge Fermi Bubbles may have occurred as a result of eruptions in the black hole in the center of the Milky Way.
The center of the Milky Way Galaxy, which also includes the Solar System, is filled with invisible and interconnected spots. The Fermi Bubbles, perhaps the largest of these invisible spots, contain energy waves consisting of radio wavelengths and hourglass-shaped X-rays.

Fermi Bubbles, as seen in the image below, are huge gas, dust and cosmic ray spheres located on both sides of the central black hole of the Milky Way. Studies on Fermi Bubbles show that literally huge bubbles extend from one end to another for about 50,000 light years. Although the bubbles are so large, they can only be seen in gamma light.

It is known that the giant Fermi Bubbles are half the size of the Milky Way, but it is not known how these bubbles appeared or where they came from. However, a new study by scientists suggests that Fermi Bubbles are linked to black hole eruptions that began about 6 million years ago, with the mysterious X-ray and radio structures surrounding the galactic center.

Scientists working on Fermi Bubbles used several simulations to determine how the bubbles appeared. The researchers determined that the Fermi Bubbles were formed by the X-ray structures located in the center of the Milky Way and a large shock wave occurring in the black hole in the center of the galaxy known as Sagittarius A *.

Scientists think that the shock wave that created the Fermi Bubbles might have connected it when it produced two enormous ionized matter eruptions that moved at the speed of light and in the opposite direction from the galactic center of the black hole.

Researchers say that when black hole eruption is large enough and strong, two identical shock waves, consisting of hot gas on both sides of the galactic center, can create. According to the researchers, in the places where the shock waves compress and heat the gas, X-ray structures were formed in the form of hourglass. In the intergalactic space, Fermi Bubbles are called all of the shock waves that expand on both sides of the black hole for thousands of light years. The researchers state that the whole process will take about 1 million years.

Scientists who conducted the study say that the eruption in the black hole produces a shock wave as soon as it passes through the halo gas. According to the researchers, this eruption, which produced shock waves, lasted for 1 million years and the Fermi Bubbles that have occurred reached their present size after 5 million years.

The shock wave hypothesis that scientists put forward explains the various features of the galactic center, including the extremely high temperatures of Fermi Bubbles and their perfectly overlapping X-ray structures at the lower edge of the bubbles.

The results of the study can be used to explain the smaller radio wave structures in the center of the Milky Way. Scientists also say that shock waves that may arise can help explain smaller structures.

ITT will produce masks from waste plastic bottles

Indian Institute of Technology (ITT) researchers have announced that they have developed high-efficiency mask making technology that can be washed and used up to 30 times using waste pet bottles.
The Indian Institute of Technology team in India, which has been on the agenda since the first day of the coronavirus pandemic has reacted to the social distance and quarantine practices, announced that they have developed a technology for high-efficiency masks.

The team has also taken a step towards environmental pollution and waste by using waste plastic bottles for the mask they have developed through the electro fiber drawing method. Researchers first smashed waste plastic bottles. Afterwards, they melted the waste plastic bottles that they disintegrated through pressed nanofiber and melting agent.

According to information shared by Assistant Professor Sumit Sinha Ray, an expert at the Indian Institute of Technology, the ITT (Indian Institute of Technology) team applied a different method for their masks that provide equivalent filtering with N95 and other medical masks. In the mask developed by the team, waste plastic bottles were preferred to obtain a nano-sized non-woven fabric texture.

In this case, one of the first things that come to your mind is whether plastic is safe for use. Sumit Sinha Ray clarifies this issue as well. It means that this nano-fiber tissue obtained from waste plastic bottles transformed into a new structure with the solution used is purified from all of the other components that cause bacteria and infections. Ray even claims that the success of these developed masks in breathing is better than many other masks available on the market.

Stating that the preference of waste plastic bottles in the development of the mask will contribute not only to environmental pollution but also to the economy, Ray adds that his production costs will be reduced by half thanks to the materials and methods they use.

Research Demonstrating that Finding Earth-like Planets Is Easier Than Thought

Published

By

A recent study reveals that the Sun-like stars in the Milky Way are more than previously thought. Scientists think that Earth-like planets can also be detected more easily, especially when they are young because of more Sun-like stars.
The list of astronomers who are struggling to find planets outside the world is quite long; but there is no doubt that one of the foremost is to find Earth-like planets. Although we do not yet have the technology to determine whether there is life there by looking at the surfaces of distant planets, we can estimate from what distance this planet is composed and even the characteristics of its atmosphere.

According to a new study published in The Astrophysical Journal, although we are fluttering to find Earth-like planets, these planets may be much more common than previously predicted. According to the data used in the research, the Sun-like stars found in the Milky Way are probably much more than previously thought. If that’s the truth, we’re facing good news for Earth-like planets.

When stars like the Sun form a system around them, Earth-like planets begin their lives as beds of liquid magma. According to scientists, it is easier to spot these magma ocean planets near Sun-like stars. Such planets emit so much heat that scientists can observe the glare from them using the next generation of infrared telescopes.

These ‘young worlds’ emit a significant part of their energy in the form of heat, making it easier to locate them. Of course, this doesn’t make things ‘easy’, it just makes it ‘a bit easier’. These positions are found in young star groups less than 100 million years old and are called ‘young moving groups’. These groups typically contain only a few tens of stars, and before we couldn’t decide if we found all the stars in each group because they were behind the Milky Way galaxy.

The good news is that it will be easier to find hot celestial bodies of liquid rocks that will eventually become a Earth-like planet. The bad news is that the Earth-like planets take millions of years to mature and cool down. Moreover, there is no guarantee that a planet with the right materials can be in an orbital region that can make life permanent.

Due to the problems caused by carbon absorption in the world, studies have started to neutralize carbon absorption in many sectors and governments. In this context, the cinema sector is also working to make the future cinema screens carbon neutral. In the past days, the first carbon-neutral, open-air cinema screening of the Middle East and North Africa region was held in partnership with Vox Cinemas and Tesla.
Dubai-based Majid Al Futtaim Group, in collaboration with the Ministry of Climate Change and the Environment and the Vox Cinemas in the United Arab Emirates, recently launched the World Environment Day with the first ‘carbon neutral’ display of the Arabian Peninsula region, which will serve Tesla vehicles. He celebrated. In addition, Majid Al Futtaim Group has announced that they are cooperating with Dubai Carbon Center of Excellence to ensure that all Vox Cinemas open-air theaters in Dubai have a carbon-neutral display. This partnership, created by Majid Al Futtaim Group with the Dubai Carbon Center of Excellence, aims to have all the Vox Cinemas open-air cinemas to be built in the future to have a carbon neutral screen.

This Vox Cinemas special screening, held on the roof of the Mall of the Emirates shopping center, is the Minister of Climate Change and Environment of the United Arab Emirates. Thani bin Ahmed Al Zeyoudi and 100 film lovers with Tesla cars attended.

Cameron Mitchell, Majid Al Futtaim Cinemas CEO, Majid Al Futtaim Group’s subsidiary, stated the innovations they aimed at the cinema sector with the following words:

“Our open-air cinema in Mall of the Emirates has managed to maintain its popularity not only since the first cinema in the Middle East and North Africa, but also since the number of cinemas opened in Dubai has increased.
