Snow in Antarctica is changing from white to green, scientists worry


Ahmedabad. May 21, 2020, Thursday

The last few years have seen amazing natural changes around the world. In which one more event has been added. The color of ice in Antarctica is changing from white to green. Scientists are also concerned about such a strange change. At present, scientists are investigating whether climate change is the cause or the cause. Some scientists believe that penguins living there are responsible for this.

Previously, only white was visible in Antarctica, meaning that only white snow was visible wherever you looked. But now there is a mixture of green with white. This green snow is especially prevalent in the coastal areas of Antarctica. Scientists are also predicting that the whole of Antarctica will turn green in the next few years.

The American space agency NASA's Sentinel-2 satellite has been taking pictures of Antarctica for two years. After the study, researchers from the British Antarctica Survey at Cambridge University have for the first time prepared a green map of the spread in Antarctica. Researchers have found evidence of this type of green ice in 1679 places across Antarctica. Scientists said there could be sea green behind the green color of the ice in different places. This green absorbs carbon dioxide from the atmosphere. The researchers said that not only green but also red and orange have been found in various places.

Ordeal before sending Gaganyaan! ISRO will do a big job on October 21, know the mission objective

Image
Gaganyaan Space: The TV-D1 test flight for Gaganyaan will be launched on October 21 at 7 am from the Satish Dhawan Space Center in Sriharikota. However, after this test, three more test vehicle missions will be conducted. The test involves launching the crew module into outer space and recovering it from the Bay of Bengal after touchdown. This includes testing the Crew Escape System (CIS), which will be used to bring the crew back to Earth if the spacecraft encounters a problem. How important is the mission? This mission of ISRO is very different and special from all the missions till now. So far all the space missions carried out by India have been unmanned. But in this mission, man will be sent from earth to space through space shuttle. After spending seven days there, he will return to earth. This process is very dangerous that is why there are very few countries in the world that have successfully carried out this type of space mission. (Photo-Twitter/ ISRO) The first test w...

Indian computers will now be ruled by indigenous operating systems, the magic of 'MAYA' will cover the Navy, Army and other forces.

Image
The Ministry of Defense has developed MAYA os with the help of various government agencies including Defense Research and Development Organization (DRDO), Center for Development of Advanced Computing (C-DAC) and National Informatics Center (NIC). It is free and more secure. The Indian government is considering replacing the Windows operating system on computers used in the Ministry of Defense with a new indigenous operating system called Maya OS. What is Maya? MAYA os is a new operating system based on Ubuntu. Ubuntu is a popular Linux distribution that uses free and open source software. Keeping up with new operating system (OS) is also a challenge for the government but the ministry claimed that MAYA OS was introduced to thwart cyber threats and reduce dependence on OS made by global tech companies like Microsoft. MAYA OS is free, so the government will no longer need to own a genuine Windows license or pay for expensive Microsoft Word and other services. Safe from cyber threats ...

Ray of hope for scientists! A rare meteorite found in Gujarat may reveal the secrets of other planets

Image
A meteorite fell in Banaskantha of Gujarat last year in the month of August. This type of astronomical phenomenon was observed after about 170 years. Before this, this kind of astronomical phenomenon was seen in 1852. Scientists stationed in the Space Department of Physical Research Laboratory, Ahmedabad have written extensively about this meteorite. The recent meteorites found in Gujarat can prove to be a very important source for understanding planetary processes. Scientists say that this meteorite is Obrite. They have confirmed that this meteorite may have formed from the rarest heterogeneous material found in our solar system. These meteorites were named Deodar meteorites. It fell on August 17, 2022 in Deodar taluk of Gujarat and is hence named as such. According to reports, the villagers saw no sign of him in the sky, only the sound of thunder.

Minor errors in documents can be corrected with smart find-replace

Image
While we prepare our Microsoft Word documents as accurately as possible , when you have to edit a report or document prepared by someone else , if the person sending you the document is not a perfectionist, he may have made a number of typographical errors, especially one . Repeatedly made the same mistakes! As many people have a habit of entering a space twice after a full stop after finishing the sentence. Many people want to put a question mark or exclamation mark at the end of a sentence by entering a space after typing the last word followed by a question mark or exclamation mark. These are all minor errors. However, when this text is to be arranged in a layout it can move. For example, if there is a space left before the question mark, it can happen that the sentence ends on the first line and the question mark is at the beginning of a new line! Such errors can also be corrected using Word's ' Find-Replace ' feature. Ctrl+h for that   Open the ...

84 Earth years are equal to 1 year on this planet, captured by James Webb using infrared wavelengths.

Image
Washington, April 27, 2023, Thursday Some give great importance to the number 84 in the philosophy of life according to the scriptures. There are millions of galaxies and billions of stars in the universe. One of the planets around the solar system is Uranus, the American space agency NASA has shared a picture of Uranus. This image was taken from the James Webb Space Telescope. Uranus is the 7th planet of the solar system orbiting the Sun. When the Voyager 2 spacecraft passed through Uranus Pass in 1986, the camera imaged Uranus as a blue-green round light, but no surrounding ring of light. According to NASA, the image taken by James Webb of Uranus using infrared wavelengths shows that the planet has bright rings around it. A special feature of Uranus compared to other planets in the solar system is that it orbits at a 90 degree tilt on its axis. Hence any season on Uranus is extreme. Here in the polar region the sun is bright for years and then it is dark for as many years. This is...
