New Delhi: How life was born on Earth. How were the things necessary for life, how did they come about? Scientists were looking for answers to all of these questions. So far, a lot of research has been done on this, but nothing concrete was known. In a recent research conducted, scientists got answers to some questions. Recent research has reinforced the fact that the essential elements for life on Earth came from Comet.

This research revealed that the comet named 67P / Churumov Gerasimenko (67P / Churyumov-Gerasimenko) contains all the essential ingredients for life.

The comet contains elements necessary for life

Studies by the European Space Agency’s Rosetta Expedition have shown that comet 67P / Churumov Gerasimenko (67P / Churyumov-Gerasimenko) contains a very important element phosphorus for life. The research, led by astrophysicist and software engineer Esko Gardner with researchers from the University of Turku in Finland, is published in the Monthly Notices of the Royal Astronomical Society.

In this, the elements necessary for life have been told. The elements necessary for life are called CHOPS, which include carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. A mixture of these six elements makes up most of the biological molecules on earth.

How did life come to earth

Scientists had also discovered elements in comets earlier. But Phosphorus was like the last part of this puzzle. Researchers found phosphorus and fluorine in 67P / Churumov Gerasimenko Comet’s internal coma. These two elements were found in solid particles deposited by Rosetta’s Ceometry secondary ion mass analysis device (COSIMA) a few kilometers from the comet.

These particles were deposited on the target plates of the device, after which their photograph was taken from a distance. All of this work was controlled from the earth itself. The research release says this is the first time that life-necessary CHOPS elements have been found in solid comets. This research is important in finding the answer to the question of how life came to earth. Phosphorus is very important for life on earth.

New Delhi: For the first time in space, scientists harvested radishes after taxiing on the International Space Station. In doing so, great success was achieved in the space mission. On social media platform Twitter, ISS Research gave the reason for growing radish by sharing the video. In fact, radish is nutritious and also grows quickly.

On November 30, NASA scientist Kate Ribbons harvested radish plants. These plants were cultivated in Bitet on the International Space Station.

Radishes grown like this

Scientists gathered the vegetables and wrapped them in foil and stored them in a cold room for a trip back to Earth during SpaceX’s 22nd Rispalli Services trade mission in 2021. The plant, named Plant Habitat -02, was first grown by NASA in a rotating laboratory. NASA chose radish because scientists understand it well and it develops in 27 days.

Radishes grow fast, but maybe not so fast! Experience a month of growing Space_Station radishes in 10 seconds.
Radishes are used for the Plant Habitat-02 study because they are nutritious, grow quickly, and are genetically similar to Arabidopsis, a plant often studied in space. pic.twitter.com/f3c8urlCei

New Delhi: There are many planets in our solar system. The smallest of these planets Mercury has completed the transit of the sun. During this astronomical event, Mercury, seen as a small black dot on the sun’s aura, moved away from the sun’s disk due to the 5.5-hour gravitational force.

To see this astronomical event, scientists used the telescope and special glasses. The diameter of Mercury is about 1,406.74 km (874 mi) larger than the diameter of our Moon.

Such an incident occurs 13 times in a century

There are 8 planets in our solar system and all of them differ from each other in size and other things. Mercury, the smallest of these planets, has completed the transit of the sun. Scientists, science students, and people interested in science had to use special telescopes and glasses to see this astronomical phenomenon. This transit of Mercury occurs 13 times per century. The next transit of Mercury will now be on November 13, 2032. This usually does not happen until May or November.

Mercury is the closest planet to the Sun.

Mercury is the smallest of the eight planets in the solar system. It is also the closest to the sun. Its rotation period is approximately 88 days. Seen from Earth, it can be seen revolving around its orbit in 116 days. This trick is considered to be the fastest among the planets. The crust of Mercury feels the strongest temperature fluctuation of all the planets.

New Delhi: Scientists are engaged day and night to find the answer to the question of whether there is life on the planet Mars. Research has revealed a lot of new information about Mars. Meanwhile, scientists have made a startling discovery. Scientists at Jackson State University, Cornell University, the Jet Propulsion Laboratory, and the University of Hawaii discovered a terrible flooding on Mars 4 billion years ago.

Wave marks

Scientist Alberto G. Firan said the first major floods were detected based on sedimentological data found by Curiosity Rover. Previously, the deposits left by the flood had never been identified. In a report published in the Journal of Scientific Reports this month, data from Gale Crater and its sedimentary layers were studied.

With its help, water, air and other factories were understood. Rover had found traces of huge waves, indicating that there was a flood.

There was liquid water on the moon

Researchers believe that a meteorite may have caused a huge flood. Because of this, the ice on Mars would have melted and carbon dioxide and methane would have started to be released. It would have changed the situation on Mars. Then there must have been heavy rains.

Is there life in the lake on Mars? Scientists have the answer to this question. However, it has yet to be disclosed properly. Alberto says the study indicates that conditions on Mars in the early days were such that there was liquid water. This indicates that life was possible there but was there life? Perseverance Rover can help you find answers to this.

New Delhi: Many studies have been carried out on the solar system, in which scientists have obtained new information. It has been said of the end of the solar system that there is too much time for it to end. Scientists had assessed the end of the solar system.

The latest study has shown that the solar system will end sooner than expected. The sun will end at the end. At that time, it will shrink into a Vamana star and after its heat slowly wears off it will turn into a cold, dead rock. It will take trillions of years, but before that the rest of the solar system will be finished.

Newton had estimated

According to the new simulations, it will only take 100 billion years for the planets in our solar system to come to an end. Astronomers and physicists have been trying to discover the end of the solar system for many years.

In new research, University of Los Angeles astronomer Joan Zinc in California, University of Michigan astronomer Fred Adams, and Caltech’s Constantine Battigin wrote that one of the oldest approaches to cosmophysics was to understand the long-term sustainability of our solar system. Even Newton had to know that.

How will the solar system end

In a dynamic system, when many objects are involved that interact with each other. The system therefore becomes more complicated. Predicting such systems becomes very difficult. This is called a bodily problem. It is impossible to make a definitive estimate on some previous time scales of the orbits of the solar system.

After 50 lakh years to crore years, his certainty completely disappears. But if we can find out what’s going to happen at the end of our solar system, then we can also find out how the universe came into being. In 1999, astronomers predicted that the solar system would slowly disintegrate in at least a billion years.

The color of the sun will change after 5 billion years

It will take time to separate the orbital resonance of Guru and Saturn. Now, according to the Zinc team, the solar system can be dispersed quickly. According to this study, after 5 billion years, the Sun will transform into the first large red body and will swallow Mercury, Venus and Earth. After the next 50 billion years, the last planet will also be separated from the solar system and after 100 billion years the sun will also stop.

New Delhi: A team of scientists working under the direction of a scientist of Indian origin has developed a new system. With this help, oxygen and hydrogen can be made from the salt water present on Mars. Scientists believe this system will bring strategic changes in space travel to Mars and beyond.

There have been indications of life on Mars in many studies. These things will draw more strength from this new system. According to the researchers, Mars is very cold. Despite this, the water does not freeze there. It is found that there may be a lot of salt (alkali) in the water there, which reduces its freezing temperature.

Efforts to keep fuel going

Scientists said that in order to convert a compound of water into oxygen and hydrogen with the help of electricity, the harvester must first be separated from the water. In such a difficult situation, with such a long and expensive process, it will be dangerous depending on the environment of Mars. The research team is led by Professor Vijay Ramani from the University of Washington, United States.

They tested this system against the conditions of Mars’ atmosphere at temperatures below minus 36 degrees Celsius.

Production is possible on March

Scientist Vijay Ramani said that our electrolyser, which splits water into two liquids under the condition of Mars, will completely change the strategic calculation of the mission of Mars and beyond. This technology is also useful on Earth, where the ocean is a viable source of oxygen and fuel (hydrogen).

The researchers said that to stay on Mars temporarily, astronauts will have to produce certain requirements, including water and fuel.

NASA’s Perseverance Rover is currently traveling to Mars. He took with him such devices that will use high temperature electrolysis. However, the Mars Oxygen In-Situ Resource Utilization Experiment (Moxi) instrument sent by the rover will only produce oxygen by taking carbon dioxide from the atmosphere.

New Delhi: People in the scientific world are in shock right now because they lost something they used to sit in one place and get information on astronomical secrets. In fact, here is the talk of the giant Arecibo telescope, which completely collapsed on December 1. This telescope was located in Puerto Rica, which has long helped scientists. Therefore, people belonging to the world of science are extremely upset by its collapse. How big is this loss, we can measure it from the fact that the country’s meteorologist Ada Monjan cried while talking about it.

Scientists are considered the largest telescope in the world
Meteorologist Ada Monjan described the collapse of this Arecibo, which has sat on the earth for more than half a century and solving the mysteries of space and has been a great loss to scientists. Giving information about this incident, she looked very moved and tears came out of her eyes. Ada said that a lot of effort was put into saving Arecibo, but alas, he has now completely collapsed. Scientists considered it to be the largest radio telescope in the world.

It was Arecibo’s specialty
Scientists are worried that now a device giving information about dangers from space, sitting on earth, has been completed. Scientists used to study huge space rocks in space thanks to Arecibo. Anne Virky, who leads the planetary radar team, says: “No other telescope can replace Arecibo. Its radar transmitter sent light to an object which collided and returned, then its radio dish made it possible to retain this signal. This gave scientists information on the position, size and area of ​​asteroids.

This is the reason for the collapse of the telescope
Arecibo’s 900 ton platform fell 400 feet into the jar on the reflective plate. The American National Science Foundation had already announced its closure. Referring to the incident, NSF said no one was injured in the crash. Arecibo is said to be in critical condition. Its Augustillery cable was cut in August, causing a 100-foot cut on a 1000-foot-wide reflector antenna. This is the reason why the platform suspended above was damaged. Arecibo’s main cable broke in early November. Astronomer and professor Carmen Pantoza of the University of Puerto Rica described it as a major tragedy. The NSF said other means would be sought to help the scientific community and strengthen ties with the Puerto Rican people.

Scientists have lost precious jewels
Dr Jonathan Freedman, a scientist who has worked at Arecibo for decades, called the incident a “storm”. He said that at first it looked like there was a high speed earthquake with heavy rain. The thunder of clouds was also heard for a few moments. Meteorologist Deborah Martorell expressed her displeasure with the incident, saying: ‘It could have been avoided. He said the bureaucracy sat down and waited for the NSF to collapse the platform. He said that Arecibo is a gem of the scientific world and it’s hard to believe it isn’t now.

Tokyo: New information about Earth and the Black Hole has been revealed. Scientists say the theory was initially different from the theory of the distance between Earth and the black hole. In this regard, a map has been published by the Japanese radio astronomy project VERA. This shows that the Earth is closer than before to the supermassive black hole in the center of the Milky Way.

It has also been found in research that our solar system is also moving rapidly around this black hole named Sagittarius A *. Its speed is about 7 km / s. According to a new project prepared by VLBI Exploration of Radio Astrometry, the supermassive black hole is now 25,800 light years from Earth, whereas in 1985, the International Astronomical Union described it as 27,700 light years.

Project started in 2000

In an official statement, the National Astronomical Observatory of Japan reported that Japanese space researchers started the project to measure three-dimensional velocities and space structures in the Milky Way in 2000 using very long-base interferometry. (VLBI). According to NASA’s Jet Propulsion Laboratory, space geodetic technology collects signals from space from an astronomical radio source. 15 years of observations were compiled using this technique. Scientists at the Japanese lab mapped the three-dimensional speeds and spatial structures of the Milky Way and the position of the Earth, and the map was published in the VERA Astrometry Catalog, which also contains data for 99 other objects. astronomical.

Much bigger than the sun

This supermassive black hole is known as Sagittarius A * or Sgr A *. Its size is 4.2 million times the size of the Sun. It was first discovered by Reinhard Genzel and Andrea Ghez using NASA’s Chandra X-ray Observatory. The goal of VERA is to get more details about the objects around the supermassive black hole.

Creating a two-dimensional map is easy
Scientists say that since our solar system does not penetrate inside Sagittarius A *, there is nothing to worry about. Scientists have prepared this map on the basis of three-dimensional speed, which is the most difficult task. It was the biggest challenge in making an accurate map of the Milky Way. It is easy to map space stars and other objects at the two-dimensional level, but it is difficult to estimate the distance between these objects.
