 NASA's Instagram picture of a melting glacier is beautiful, but also a threat!


By the time of writing this news, the picture had been liked by over 9 lakh users. Many people appreciated the beauty of the picture and many users expressed concern about climate change and global warming.


NASA shared a picture of a melting glacier on its Instagram account. As beautiful as this picture is in view, its truth is as frightening. This picture shows that we are falling prey to global warming very fast. This photo is taken by a French astronaut Thomas Pesquet from the International Space Station (ISS). It overlooks the Upsala Glacier, the third largest glacier in the southern Patagonian icefields of Argentina and Chile. The US Space Agency says that our glaciers are becoming smaller and that these changes are visible to astronauts from space, as well as the Earth Observation Satellite providing climate scientists with information about the home environment. This picture clearly shows that a large part of this huge glacier has broken due to global warming and it is melting rapidly.


NASA's caption in the picture says that as the climate changes on Earth, the International Space Station is sending photos of these changes to make our planet safer.




The only eye on earth is also visible from space.

Whenever an astronaut approaches the space station, an eye is kept from the earth on it. Most astronauts take photographs of this eye from the space station. Make a video. Because this eye is so big that this earth is visible even from the space station orbiting about 450 kilometers. This eye is completely round. Its diameter is 50 kilometers. That's why astronauts see it with open eyes.



This eye has many names. This is called the eye of Sahara. That is, the eye of the Sahara desert. It is located in Mauritania, North-West Africa. Therefore, it is also called the Eye of Mauritania. It is in Africa, so it is also called the Eye of Africa. Scientists believe that it was a naturally finished plateau dome. Due to continuous erosion, now only a circular layer-by-layer crater is left. (Photo: Nasa)


Scientists call the Eye of Sahara the Richat Structure. Spherical rings are made around this structure. The outer part of each ring is rocky and plateau, while the inside is dark and sandy. This place is not known only scientifically. It is also called the bastion of Acheulean archaeological artefacts here. The rings you see around it are not just stones. There are brown stones. There is yellow and white sand. There are green plants and thorn bushes. What is visible in blue is salt. (Photo: Nasa)


Acheulean was an ancient civilization, where stone instruments and tools were made. It was here that humans discovered the ax and hammer. This civilization was spread all over Africa at that time. Apart from this, it also had its empire in South Asia i.e. all over India, Pakistan, Afghanistan, South-eastern part of China, East Asia, Middle-East Asia and European countries. It is believed that the technique of making instruments and tools from stones was discovered here 10.76 crore years ago. (Photo: Nasa)


In the eye of the Sahara Desert, the rich structure, there are many types of stones. There are also Rhyolitic Rocks, which must have flowed with lava at some time. Apart from this, gabros, carbonatitis and kimberlitis were also present. Gabbros are stones that make two rings inside. The ring of most difference is also like this. It is built at a distance of 3 km from the center. The width of this ring is 20 meters. (Photo: Nasa)


When scientists found out the age of Carbontitis here, it was found that it is from 94 million years to 104 million years old. Scientists think it was an ancient dome. It was discovered by scientist Richt Mollard. Then in 1952 the scientist Theodore Monod studied. Then gathered information about these stones. (Photo: Nasa)



There is also a collection of archaeological rocky artifacts of Achulian civilization in the Richt structure. Archaeologists often go and study here. Spears and arrows of Neolithic era have also been found here. Which were made from stones. A large number of sediments are also gathered here. This sandy deposit is from 9.8 feet to 13.1 feet height. In Arabic language, this place is called Kalb-e-Rishat (Guelb-er-Richat). (Photo: Nasa)






Fast Radio Bursts: Where are mysterious radio waves coming from? Hubble Telescope discovers distant Galaxy address


For the first time, so many FRBs have been seen in high resolution and Hubble has shown that they are on or near the spiral arm of a galaxy. Most of the giant galaxies are still new and are becoming stars.



There are many puzzles of the universe that are yet to be solved. Fast Radio Bursts, FRBs is also one of these. These very short and intense radio wave pulses come from deep space but the reason behind them is not yet understood. Now the Astronomers have detected the galaxies from which the 5 FRBs are coming.
