Did the extinction of the dinosaurs begin even before the asteroid collided?


Mexico, December 6, 2021, Monday

Scientists have long debated how the giant dinosaurs that roamed the earth millions of years ago became extinct. The most well-known theory for the extinction of dinosaurs is that asteroids or meteorites collide with Earth. The Chicksulab meteorite collided around the Yucatan Peninsula in Mexico 25 million years ago, triggering the cataclysmic palaeogen extinction.


According to another theory, dinosaurs could not survive the beginning of the ice age due to climate change. According to recent claims, the extinction of dinosaurs began 10 million years before the asteroid collided with Earth. According to a study published in the journal Nature, figures and findings from 1,200 dinosaur fossils found around the world were looked at. Based on this, researchers have developed a model. In the North Cretaceous, carnivorous and herbivorous dinosaur species were found roaming. Fabian Kodamine, a researcher at the Matpillars Institute of Revolutionary Sciences and lead author of the new study, said there was a special focus on the process of reducing the number of dinosaurs. There were more than 50 species of dinosaurs, with their population at an all-time high of 25 million years ago. Since then, the number of dinosaurs has been declining for 10 million years.


The dinosaurs were accustomed to a mesothermal environment that kept them warm and humid. Gradually the weather began to decline with the onset of cold. With the onset of cold weather, the average temperature reached 4 degrees. Giant creatures, including dinosaurs, have not been able to adapt to the growing cold. At first the vegetarian and then the carnivorous species began to dwindle. The period between the two was 3 million years. In the midst of all this, some species of dinosaurs survived, but were wiped out by meteorite collisions. The decline of dinosaurs began 10 million years ago. About 40 species of dinosaurs were found.

Solar Flare Strom: Earth may be in the path of solar flares, NASA warns

Image
New delhi date. 26 April 2023, Wednesday Not even 24 hours have passed since last week's solar flares reduced in intensity. There, the American space research agency NASA has once again expressed the possibility of solar flares. NASA said that the storm from the Sun will be more dangerous than before. This storm is going to have a direct impact on the world. It can also have a major impact on the Earth's magnetic field. Due to which GPS and internet connection may be interrupted. What are solar flares? According to NASA scientists, solar flares are caused by massive bursts of plasma and magnetic waves from the Sun's core. As a result, billions of solar particles can be scattered all around. Its impact on the solar system cannot be stopped. A week ago, a storm in the form of solar flares was observed in the solar system. His light also came to earth. The Indian Ocean was the most affected by the solar storm. Due to which there were some hiccups in the wireless connectio...

NASA's Artemis-1 launch in trouble again, mission hit after fuel leakage

Image
Washington, September 3, 2022, Saturday As part of America's plan to go to the moon, the Artemis-1 mission is back in the spotlight. NASA scientists discovered fuel leakage and engine failure in the rocket just hours before launch. This is the second time a mission has had to be postponed in a single week. Ortemis-1 mission was to be launched from Kennedy Space Center in Florida. Hence, a new schedule will be arranged for the third time in the near future. However, the date and time of the third attempt has not been fixed. NASA's Artemis mission aims to send a man to the moon by 2025. Currently, a capsule named Orion has been prepared. The capsule is to orbit the moon for 42 days to collect data. Based on data and information from Orion, the spacecraft is to go to the moon. So the Artemis-1 mission is very important but the program of the mission has been hit by a technical fault again in the rocket carrying Orion into space.

The oldest galaxies discovered by the Webb Telescope are estimated to be 13 billion years old

Image
Image Envato Dt. 5 April 2023, Wednesday The James Webb Space Telescope has discovered the four most distant galaxies ever discovered. New research suggests that this galaxy formed 320 million years after the Big Bang, when the universe was in its infancy. Since the Webb Telescope began operating last year, it has opened new doors of discovery for scientists. With the help of this telescope, scientists are searching for new galaxies in the universe. The longest distance at which the universe has been observed by astronomers Astronomers said they have discovered the four most distant galaxies ever. These galaxies formed 300 to 500 million years ago after the Big Bang, 13 billion years ago. The most distant galaxy is called JDES-GS-J 13-0, and is the farthest distance observed by astronomers, said researcher Stéphane Charlot of the Astrophysics Institute in Paris. The masses of all the four galaxies found are very low The Webb Telescope also confirmed the existence of JADES-GS-z10...

World Asteroid Day 2020: Why is this day celebrated today?

Image
New delhi date. 30 June 2020, Tuesday It was a fateful morning. People saw a very bright and intense light on the earth just like the sun. Ten minutes later a loud explosion was heard. This was a huge explosion. Witnesses said the blast was so powerful that the ground shook like an earthquake. Hundreds of kilometers away, the windows of people's houses were broken. About 80 million trees were uprooted within a distance of two and a half thousand kilometers. As if the abyss had not been broken. This horrific event was caused by the collision of a huge asteroid (meteorite) with the Earth. The collision caused an 8 km deep pit to fall into the ground. This place has been deserted for more than a hundred years. Even today no tree or plant can grow here. This event is considered to be the largest asteroid collision in history. The event took place on June 30, 1908 in Tunguska, Russia, known in the astronomical as well as space world as the Tunguska Event. Not only this, in the world ...
