A new analysis of lunar rocks brought to Earth by Apollo astronauts suggests that the moon formed 4.51 billion years ago — just 60 million years after the solar system itself took shape.
Scientists have dated the moon to at least 4.46 billion years old. To date the moon, the researchers obtained lunar dust collected by Apollo 17 in 1972 and analyzed the tiny zircon crystals and uranium contained inside. As they expected, not all of it had decayed into lead, a process that takes billions of years.
Moon, Earth’s sole natural satellite and nearest large celestial body. Known since prehistoric times, it is the brightest object in the sky after the Sun.It is designated by the symbol ☽. Its name in English, like that of Earth, is of Germanic and Old English derivation.. The Moon’s desolate beauty has been a source of fascination and curiosity throughout history and has inspired a rich ...
The Moon is the only other planetary body that humans have visited. On July 20, 1969, NASA astronauts Neil Armstrong and Buzz Aldrin were the first people to set foot on the dusty surface of the Moon. ... There is no wind or air on the Moon to help “erase” craters, so the surface is covered with the remains of old and new impacts. Credit ...
The usual English proper name for Earth's natural satellite is simply Moon, with a capital M. [19] [20] The noun moon is derived from Old English mōna, which (like all its Germanic cognates) stems from Proto-Germanic *mēnōn, [21] which in turn comes from Proto-Indo-European *mēnsis 'month' [22] (from earlier *mēnōt, genitive *mēneses) which may be related to the verb 'measure' (of time).
Like Earth, the Moon has a day side and a night side, which change as the Moon rotates. The Sun always illuminates half of the Moon while the other half remains dark. NASA’s LRO mission has used its seven science instruments to map the entire lunar surface, including the Moon's near and far sides, down to a scale of one meter.
By analyzing tiny lunar crystals gathered by Apollo 17 astronauts in 1972, researchers recalculated the age of the Earth’s Moon. Although previous assessments estimated the Moon as 4.425 billion years old, the new study discovered it is actually 4.46 billion years old — 40 million years older than previously thought.
By analyzing tiny lunar zircon crystals gathered by Apollo 17 astronauts in 1972, researchers recalculated the age of the Earth's moon. Although previous assessments estimated the moon as over 4.42 billion years old, the new study has discovered it is 4.46 billion years old — 40 million years older than previously thought.
Lunar dust collected by Apollo 17 astronauts in the 1970s has revealed that the moon is 40 million years older than previously believed. After landing on the moon on December 11, 1972, NASA ...
A new study of lunar minerals has captured the last stage of the moon solidifying into rock. ... scientists have determined that the moon is at least 4.46 billion years old.
