2021年金星の旅 新発見の姿と生命の可能性 | ガリレオX第247回

July 2021 Broadcast Childhood memories of finding the first star. That star is almost always Venus. Venus, the closest planet to Earth, shines brightest of all celestial bodies, excluding the Sun and Moon, thanks to the "clouds" that cover its entire surface, reflecting sunlight well. Its brightest star is due to its proximity and brightness. But Venus' proximity isn't just due to its proximity. Its diameter is 0.95 times Earth's, its mass is 0.82 times Earth's, and its internal structure is thought to be nearly identical to Earth's. It's so similar to Earth that it's often referred to as Earth's "twin planet." However, it also remains a planet shrouded in mystery. This is due to the aforementioned cloud cover. Research into this mysterious planet, Venus, is now revealing new facts one after another. Some even suggest the possibility of extraterrestrial life. We explore the true nature of Venus as revealed by observations from the Akatsuki spacecraft and the Atacama Large Millimeter/submillimeter Array (ALMA).
