A 500-million-year-old volcano has been discovered on Mars, and life is expected

मंगल ग्रह पर मिला 500 ​​मिलियन साल पुराना ज्वालामुखी, मिल सकते हैं जीवन के सबूत

New Delhi.

NASA scientists have found evidence that an area on northern Mars known as Arabia Terra has experienced thousands of “super eruptions”, the largest volcanic eruption known in 500 million years. Scientists estimate that the explosions hit the surface of Mars about 4 billion years ago, releasing water vapor, carbon dioxide, and sulfur dioxide into the air.

Patrick Weil, a geologist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said: “Each of these explosions had a significant atmospheric effect – perhaps releasing gas that thickened the atmosphere or blocked the sun and cooled the atmosphere.” . ”

“Models on Mars’ climate will need some work to understand the impact of volcanoes, ”he said. After an explosion the equivalent of 400 million Olympic-sized swimming pools of molten rock and gas, thousands of miles away from the eruption site, a volcano of volcanic size would fall into a huge crater. Called “Caldera.”

The caldera that exists on Earth is dozens of miles wide. The team found that the seven calderas on the Arabian Terra were the first degenerate volcanic eruption in the region. The team’s analysis followed the work of other scientists who had previously suggested that the minerals on the surface of the Arabian Terra were of volcanic origin.
