New Delhi: For the first time, astronomers have captured a radio signal indicating a hidden planet in a crucial discovery. These signals are captured by the low-frequency array (LOFAR) of the Netherlands' most powerful radio antenna in the world.

The new technique of finding hidden planets can also provide information about life outside the solar system, which has been the biggest question for astronomy so far. Are we alone or is there anyone else. Dr. of the University of Queensland. The discovery was made by Benjamin Pope and his associates at the Dutch National Observatory Astron. Astronomers are searching for planets using LOFAR.

Astronomers have discovered 14 distant red dwarfs, four of which are known to be orbiting planets. We have long known that the magnetic fields of our solar system planets emit powerful radio waves when they are exposed to the solar wind, but we have not yet been able to capture the radio signals outside our planetary system.

Previously, every astronomer could detect the nearest star only by radio current coming at a constant rate. Radio astronomers could now see the old plain old star when they observed the red dwarf stars. This star is much smaller than the sun.

According to a study published in Nature Astronomy, the team believes that these signals come from the magnetic attachment of the stars and are orbiting invisible planets around them. A similar harmony is observed between Jupiter and its moon. Dr. of Astron Leiden University. Joseph Collingam said that our Earth also has an aura, it is more prevalent mainly at the North and South Poles. Here the Earth's magnetic field is more exposed to the solar wind, so more radio waves are emitted.

For the first time, NASA is sending a drone helicopter to Mars

Image
New delhi date. Thursday, July 30, 2020 Man has always been experimenting and inventing new things. It has always been interesting to know about the different planets in space. Mars is the most special of these, as it is believed that if there is any planet other than Earth that could be habitable by humans, it is Mars. There is also ample evidence of the existence of water here. The search is still on. The US space agency is launching the Mars mission. The peculiarity of this mission is that for the first time NASA will also send a drone helicopter to Mars along with the rover. For this reason the mission is named Perseverance Mars Rover and Ingenuity Helicopter. According to NASA, the rover will collect information by walking on the surface of Mars while the helicopter will receive information by flying. The Mars rover weighs 1000 kg while the drone helicopter weighs two kg. The rover is also fitted with a Mars Environmental Dynamics Analyzer which will get information about the t...

Five decades after man's arrival, 'moon trip' difficult, 60 out of 146 missions fail

Image
India tried to land on the moon in 2019 which failed. In 2023, India's space agency ISRO successfully landed on the moon. India is the first country to successfully land on the South Pole of the Moon unscathed. This success of India is also big because so far a total of 146 lunar missions have been launched out of which 60 have failed. Only four countries made a soft landing on the lunar surface According to Dr. Gail Isles of RMIT University, Australia, the Moon is the only celestial body other than Earth where humans have set foot. It also makes sense to go there first as it is our closest object at about four kilometers away. Interestingly, only four countries have made a soft landing on the surface of the moon so far. On the other hand, its South Pole is still mysterious, where only India has been able to reach. So many countries have failed Even Russia, the first country to make a soft landing on the moon 60 years ago, recently failed to land Luna-25 on the moon's sout...

If you are interested in astronomy due to solar eclipse, let us know about an app to install in your phone.

Image
A cosmological app in the palm of your hand! An exciting event took place in space yesterday - a circular solar eclipse or say 'Ring of Fire' solar eclipses! The spread of the corona virus has disrupted daily life on Earth, but everything in space is moving at a steady pace! Yesterday's solar eclipse was the result of such a fixed, fixed, annual cycle of events! We all know that the various planets in our universe revolve around the immovable sun, these planets have their own satellites. The earth itself rotates on its axis, tilted slightly, and at the same time revolves around the sun. If we talk only about the earth, due to the orbit of the earth around the sun, the motion of the earth on its own axis and the orbit of the moon around the earth, various exciting astronomical events are created. One of them is this kind of annual annular solar eclipse. Such a solar eclipse occurs when the Sun, Moon and Earth are in a straight line, all three on almost the same surfac...

Voice typing will become easier and faster

Image
Ahmedabad. 11 November 2020, Wednesday With the help of Google Assistant in Gboard, typing can be done without touching the screen. The way we type in all our smartphones also changes over time. With PCs and laptops having relatively large keyboards, we didn't need any of its alternatives, but most people don't like typing on a small screen in a smartphone, even on a small keyboard. That's why tech companies are trying to make smartphone keyboards smarter and easier to use. Keyboards like Google's Gboard and Microsoft's Swiftkey have come a long way in this direction. Adding either of these keyboard apps to your smartphone can make your typing much faster and more convenient, just be prepared to learn new ways of typing by scrolling across different alphabets on the screen without lifting a finger from the keyboard. Without such preparation, voice typing is now becoming more convenient. Many people have a habit of sending voice messages instead of messing aroun...

Is a solar storm moving towards the earth at a speed of 12 lakh km per hour?

Image
New York, October 16, 2021, Friday With the development of space science, new information about space and planets is coming out. According to the information received, a tremendous solar storm is moving towards the earth. Solar storms could hit Earth in a matter of hours, according to a new US warning. Researchers are divided over what effect this will have on the Earth, but some believe it could have an adverse effect on power supplies, GPS systems and mobile signals. Scientists have warned that Northern Lights from space could also appear in the US and UK. The U.S. National Oceanic and Atmospheric Administration says a solar storm could cause lightning in many parts of the earth. Magnetic force can also be felt in some places. This can also damage the power grid. The storm, which started on October 11, has intensified since October 15. It is moving at a speed of 12 lakh km per hour. The last time such a dangerous storm occurred was in 19. However at that time there was no promoti...

Solid evidence of flowing water on Mars, the red planet of the Solar System: Images of pebbles and rocks found

Image
- Amazing exploration of NASA's Perseverance rover - Rocks and pebbles found at Castel Henlez, near Jezero Ulcakund, must have been washed up by stormy river floods in the past. Washington/Mumbai: The mysteries and wonders of our solar system, including the infinite universe, are also being discovered. Earth's neighbor and the red planet of the Solar System, Mars, has strong evidence of past flowing water. The Perseverance rover of the American space research organization National Aeronautics and Space Administration (NASA), which is researching on Mars, has found strong evidence of water flowing on the surface of Mars in the past, i.e. millions of years ago. Evidence has been found. Now, based on all these evidences, there is also a strong indication that if there was flowing water on this red planet in the past, there must have been a phase of life there.

The government tightened the grip on social media even more

Image
In India, the government and social media have long been at loggerheads over freedom to publish content and government control over it. For a few years now the Indian government has started imposing restrictions on social media and now last week India's IT Act has been amended once again. Accordingly, Facebook , Twitter and other social media shall not publish or host any false or misleading information regarding the working of the Government. Before publishing any such information, the social media companies have to check the authenticity of the information with the help of fake check unit set up by the government. It is natural that social media is protesting against this new provision. As India is a huge market for companies like Facebook , Twitter and Google, it is obvious that any kind of restrictions would be harsh on them. But in addition to this, organizations like Journalists and Editors Guild of India have also raised objections. According to all of them, this provi...

What do you know about the world's most poisonous tree growing on the south coast of India?

Image
Chennai, July 30, 2020, Thursday Every plant and herb on earth has some medicinal properties. Life without vegetation is unimaginable. However, in some countries of South East Asia, including India, it has been nicknamed the Suicide Tree because of the poisonous tree called Sarbera odolam. This tree is as dangerous as it looks green and attractive. In addition to its fruits, flowers and leaves, the seeds also contain a toxic element called cerberine which can kill a person instantly. Even a normal dose of it can cause stomach upset, pain, and vomiting. The heartbeat seems to be irregular. In addition, no medication or treatment is effective. It is as if the poison is injected into the body. The most surprising thing is that if one eats the fruit by mistake, the medical examination does not even notice it. Botanists and researchers believe that this is the most dangerous tree in the world. The venom of this tree has been compared to the venom of a cobra. Every month 4 people die from...

Impact of global warming: The country's last 4,000-year-old iceberg also collapsed

Image
Toronto, Ta. 09 August 2020, Sunday Much of the final iceberg in Canada has collapsed due to warmer climates and rising global temperatures, turning it into vast iceberg islands. An iceberg is a floating piece of ice formed by the erosion of a glacier or glacier from the ground to the surface of the ocean. According to scientists, Canada's 4,000-year-old iceberg on the northwest corner of Ellesmere Island was the country's last intact iceberg by the end of July. Adrian White, an ice analyst at the Canadian Snow Service, found that 43 percent of the images taken by satellite were broken. He said this is an event around July 30 or July 31. White said the iceberg had broken into two huge icebergs as well as smaller ones, and that the iceberg had already begun to float. The largest glacier is about the size of Manhattan i.e. 55 square kilometers and this is 11.5 kilometers long. While its thickness is 230 to 260 feet. He said this is a huge, very large piece of ice. "If a...
