Fear of corona, asteroids also come out wearing 'masks', scientists surprised


Nainital, Ta. 30 April 2020, Thursday

A very large and potentially dangerous asteroid passed close to Earth on Wednesday and its images took scientists by surprise. Looking at the images of the asteroids, the scientists got the impression that they were wearing masks on the planet. However, that illusion was in fact caused by the lines formed in the small mountains and plains that came over it.

The asteroid passed at a speed of 19,000 km per hour on Wednesday afternoon, maintaining a safe distance from Earth. However, the scientists had already clarified that there was no danger from it and it was constantly being monitored. Scientists named it (52768) 1998 OR2 and on April 29 it passed closest to Earth.

According to Shashi Bhushan Pandey, a scientist at the Aryabhata Institute of Observatory Science and Research (ARIS), the asteroid that passed by on April 29 was relatively large and could have caused a disaster if it had collided with the Earth. Although it passed closest to Earth, it was at a distance of 6.3 million km, which is 16 times the average distance between the Earth and the Moon.

NASA placed it in the range of potentially dangerous asteroids. Such potentially dangerous asteroids pass close to Earth's orbit at a distance of less than 7.5 million km. According to this measure, it passed close to the earth at a distance of 12 lakh km less than that.

Orbiting the Sun between Earth and Mars in 1,344 days, the asteroid will now pass close to Earth again on May 18, 2031, but at that time it will pass a further 19 million km.

A small asteroid gave him company

Now in 2048 and 2062 It will pass farther but on April 16, 2079 it will pass very close to the Earth at a distance of only 1.8 million km and if for any reason it will wander, it will prove fatal to the Earth. Apart from this big asteroid, there is also a small asteroid that seemed to be giving him company. It passed around it a few thousand kilometers from Earth and scientists named it 2020 HS7.

Scientists reported that there was no danger to Earth from small asteroids. Small asteroids of this shape pass safely very close to the Earth every month. The 2020 HS7 had a diameter of four to six meters and even if such a small asteroid collided with the Earth, it would be destroyed in the Earth's atmosphere before it.

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...

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...

The transmission power of Corona virus sticking to the surface decreases after 5 days - research

Image
London, 10, June, 2020, Wednesday It is common knowledge that the corona virus is spread from person to person through sneezing and nasal and oral droplets, as well as if the corona virus is spread on a plastic metal or other surface. There has been a lot of research on how long the corona virus survives on which surface, but the research done by the University College London in Britain is shocking. According to research published in the Journal of Hospital Infections, corona viruses can live on any surface for up to five days at most. It can spread to a large area within the first 10 hours when the transmissible power of the corona virus, which landed on the surface on the fifth day, was reduced. Observed after 10 hours, it spread to every corner of the ward. During the experiment Corona used a virus to infect artificial plants with a virus for a patient's breath that could not infect a man. Both viruses were then found in a drop of water and left on the bed railing. The viru...

Image
Washington, October 31, Saturday The research of Dr. yanasora research goes beyond the nitanavi information. The dinosaurs of the species called pterosaurs were the first creatures to know the art of flying in the sky. The age called Triassic lasted from 23 to 190 million years ago. Many gigantic animals existed at that time. Fossil scientists are still gathering information about reptiles that can fly in pairs. These dinosaurs preceded the T-Rex, Triceratops and Cretaceous-era dinosaurs. However, according to numerical methods, biophysical models and fossil records, terosaurs could fly superbly 150 million years ago. In the report, Joanna Baker, a professor at the University of Reading, says the pterosaur was indeed a unique creature. Gradually his flying ability was constantly increasing and improving.

IIT researchers develop real-time underwater marine robot, eases deep-sea surveillance

Image
image : Envato and Twitter Real-time underwater marine robot: Indian Institute of Technology (IIT) Mandi and Palakkad have achieved a tremendous achievement in developing real-time underwater marine robot for underwater surveillance. The function of this robot will be close underwater monitoring and verification. Its level of efficacy would be very high, risk would be extremely low and it would likely be cost-effective, the researchers said. Jagdish Kadian, assistant professor at the Center for Artificial Intelligence and Robotics at IIT Mandi, said that learning about the ocean's internal currents from history led to the conclusion that only by placing instruments on research ships deep can one gain more insight into the ocean. Kadian, a co-author of the study, said that a typical cruise ship stays on the surface for a month or two, limiting the possibility of producing a comprehensive report on the sea. So it has often been said that changes in the sea do not wait for a ship ...
