Earth ‘has been lucky’ to support life for 3 billion years, study says

Technology
Planet Earth's success in staying habitable for billions of years is partly down to luck, according to a new study.A mass simulation experiment suggests most planets would not have been able to cope with changes to their climate while still supporting life for the three billion years Earth has, scientists have said. Researchers at the University of Southampton put 100,000 randomly generated planets through the effects of climate evolution 100 times each.Just 8,700, less than 10%, stayed the course at least once, according to the study, which was published in the Nature journal Communications Earth and Environment.And almost all of these (8,000) completed the span fewer than 50 times out of 100, while more than half (about 4,500) were successful fewer than 10 times out of 100. ...
First moon samples for more than 40 years brought back to Earth

First moon samples for more than 40 years brought back to Earth

Technology
A Chinese lunar spacecraft capsule has returned to Earth with the first fresh samples of rock and debris from the moon in more than 40 years.The newly-collected rocks are thought to be billions of years younger than those obtained earlier by the US and former Soviet Union, offering new insights into the history of the moon and other bodies in the solar system. They come from a part of the moon known as the Oceanus Procellarum, or Ocean of Storms, near a site called the Mons Rumker that was believed to have been volcanic in ancient times.As with the 382kg of lunar samples brought back by US astronauts from 1969 to 1972, they will be analysed for age and composition and are expected to be shared with other countries.

China says its spacecraft sent to bring lunar rocks back to Earth has collected its first samples, adding to a string of successes for Beijing’s increasingly ambitious space programBy JOE McDONALD Associated PressDecember 2, 2020, 9:30 AM• 4 min readShare to FacebookShare to TwitterEmail this articleBEIJING -- A Chinese spacecraft took samples of the moon's surface Wednesday as part of a mission to bring lunar rocks back to Earth for the first time since the 1970s, the government said, adding to a string of successes for Beijing's increasingly ambitious space program.The Chang’e 5 probe touched down Tuesday on the Sea of Storms on the moon's near side after descending from an orbiter, the China National Space Administration said. It released images of the barren landing site showing the la...
