An outer moon at eight thousand light-years

An outer moon at eight thousand light-years

Astronomers have claimed that there may be another moon outside our solar system. The satellite was observed by the Hubble Telescope after data from NASA's Kepler spacecraft revealed its existence.

Astronomers have suggested that there may be another moon outside our solar system. It is separate from the celestial bodies in our sky. As large as the planet Varun in size, that potential satellite orbits the planet Jupiter. But its mass is 10 times more. The satellite was observed by the Hubble Telescope after data from NASA's Kepler spacecraft revealed its existence. Research by astronomers David Kipping and Alex Tichi has been published in the journal Science Advances. But they point out that more observation is needed to understand the distant planetary system.

Dr. who works at Columbia University in New York. "Every effort has been made to distinguish between the observations of the spacecraft and the activities of other planets or stars," Kipping said. "But we have not been able to find any other theory that can explain all the data we have," he said in a statement. So far, astronomers have discovered more than 3,500 extraterrestrial planets orbiting stars other than the Sun. At the same time, the satellites of the member planets of the solar system, i.e. the outer moon, have also been discovered. But those satellites are far beyond the capabilities of current technology.

Researchers observed a planet named Kepler Sixteenth Twenty-Five B orbiting its mother star. During the 19-hour-long transit, the light was blocked by the star. That star is 8,000 light-years away from Earth. Kipping and Tichi sought two clues to show the existence of an extraterrestrial in data collected from different transits. The first sign was that Mautara's brightness was diminishing as the outer moon moved forward. The delay in the transit of the planet in front of Mautara was the second sign.

"The location, size, and depth of this phenomenon are similar to the time when a moon the size of Varuna passes in front of its star," says Kipping. It orbits its planet from an orbit 3 million kilometers away. Three-and-a-half hours after the planet's transit, the Hubble Telescope recorded the star's brightness for the second time.

"The dog tied to the rope indicated that it was following its owner, following the moon to its planet," Kipping said. The transit took place a quarter of an hour earlier than expected. According to him, there are some signs of gravity on the planet. According to Tichi, the available evidence points to the existence of the moon. He says, "That's why we have to be careful here. The announcement of the first extraterrestrial is an unusual claim and requires unusual evidence. But he says he is excited about the discovery. Kipping, who has been searching for satellites for more than a decade, announced the study of a possible lunar eclipse with colleagues Tichi and Alan Schmidt in July last year.

Increasing space pollution

A study by the European Space Agency has warned that the number of satellites launched into space could rise sharply and cause significant damage. Dr Hugh Lewis, who led the study, said the cost of building satellites was so low that "satellites" were now being built into space. According to experts, space is becoming more and more crowded. He stressed the need to reduce the size of satellites and deploy missions to remove useless satellites.

An American space surveillance network has estimated that the 42,000 pieces floating in space are very large. But many such objects are less than four inches in diameter and cannot be monitored. However, it is said that the danger posed by them being small is not small. Because it is wrong to understand that the garbage floating here means the pieces that are standing still. These pieces are moving at the rate of 35,000 kilometers per hour. Even small nut bolts that turn here are more dangerous than bullets from a pistol. Because the maximum speed of a speed bullet is only 3000 kilometers per hour. Now imagine for yourself how dangerous even a small piece of nut bolt can be for our other satellites.

Brian Weiden of the Secure World Foundation, an organization that emphasizes the sustainable use of space, said: "Right now, we don't even monitor very small objects. Such objects can cause problems when they collide with a satellite. Although the chances of these pieces colliding in space are very low now, no matter how low the chances of them colliding now, such incidents have not happened in the past.

In 2009, the United States collided with a commercial communications satellite and a Russian weather satellite. In 2017, a team from the International Space Station had to rescue Soyuz from a rocket due to satellite debris. It is estimated that it will take at least hundreds of years to remove millions of such debris from the earth's orbit. Today, scientists are experimenting with how to clean up space debris.

About 7,000 satellites have been sent into space so far, of which only 1,500 are in operation. In the next decade, satellites are likely to take the shape of giant constellations, as the number could rise to 18,000. Large satellites are being prepared to expand the quality and accessibility of the Internet globally. Scientists such as Widen of the Secure World Foundation say that the challenges will be even greater when more satellites are launched.

Almost all objects in space have the same speed relative to their height. Weiden says that if everything is going in the same direction, it will not have much effect. Laurie Newman, a member of NASA's traffic watchdog, says strengthening the exterior can protect satellites from objects smaller than a centimeter.

But according to him, other objects from one to 10 centimeters that cannot be detected could cause damage to the satellites. Satellite technology is becoming a basic necessity of modern human life. Whether it's weather information or information communication information or Google Maps that we use to find a location, all of these are connected to satellites. Such space waste does not necessarily endanger any one country. Therefore, to solve such a problem, it is necessary to work with every country for the security of space. The United Nations formed the Committee on Peaceful Uses of Outer Space (COPUOS) in 1959.

It now includes 85 countries, from space powers such as the United States, Russia, and China to countries that have not been able to send a single satellite but are using satellite technology to Costa Rica. Australian scientists are developing a powerful "laser" technology that can be used to clean up space debris. According to scientists, there are millions of different pieces orbiting the earth in space. Scientists have suggested that these objects could cause damage to satellites. Such objects include rocket and spacecraft parts left behind.

Researchers believe that laser technology can prevent unwanted objects in space from colliding with satellites. The purpose of the test is to develop a larger and more powerful laser. It will pull such remnants from space into the Earth's atmosphere, and then it will burn to ashes. The system will operate from outside the Australian capital, Canberra. At present, it is estimated that there are seven and a half thousand tons of garbage in space. Similarly, some scientists have been involved in the development of large mesh and long and sharp spears to clean up such debris in space. Such nets will collect the debris scattered in space and bring it to the Earth's atmosphere, which will burn to ashes due to friction in the Earth's atmosphere.
