For the first time in human history, we Rudimentary planetary defense technology It may one day prevent a major asteroid impact. But new research from NASA’s Goddard Space Institute draws attention to a more likely and harder-to-solve apocalypse: volcanoes. The study cites Venus as an example, where periods of volcanic activity lasting millions of years may have transformed the world from a watery world into the inhospitable hellscape we see today. suggests that there is a
Venus is considered Earth’s sister planet — the planets have similar sizes and densities, but the surface conditions could not be more different. Venus’ atmosphere is over 90 times denser than Earth’s. , composed mostly of carbon dioxide. The planet is suffering from a runaway greenhouse effect with an average surface temperature of 864 degrees Fahrenheit (462 degrees Celsius).
the study It focuses on the effects of the “large igneous field” or LIP, a period of widespread volcanic activity. On Earth, these conditions can persist for thousands of years and are responsible for more mass extinctions than asteroid impacts. , is nothing compared to the fact that more than 80% of Venus’ surface is solidified volcanic rock.
“Understanding the record of large igneous regions on Earth, Venus, allows us to determine whether these events may have caused Venus’ current state. ” Lead author Dr. Michael Way says:In this study, we assessed the potential impact of LIP when each event occurred in clusters 100,000 to 1,000,000 years apart. The team also evaluated the cumulative impact of her LIPs occurring randomly throughout Venus’ history. In both cases, the study concludes that environmental effects of LIP may have caused Venus’ heat death. On the other hand, the Earth may have narrowly escaped complete destruction.
Venus is a notoriously difficult planet to study. The only probe to reach the surface was destroyed within minutes by crushing pressure and acid clouds. NASA’s future missions It may shed light on the history of the Earth. DAVINCI (Deep Atmosphere Venus Investigation of Noble Gas, Chemistry, and Imaging) can reveal the history of Venus’ water and how its climate has changed over time. Da Vinci is currently scheduled to reach Venus towards the end of the decade. Next up is the Venus Emissivity, Radio Science, InSAR, Topography and Spectroscopy (VERITAS) mission, the Orbiter to analyze the planet’s surface.
