The premise of Rare Earth is that microbial life is common throughout the universe while animal life is rare. How can this be? Because microbial lifelife in its most basic formis extremely hardy.
Their rare Earth hypothesis predicts that while simple, microbial life will be very widespread in the universe, complex animal or plant life will be extremely rare. Ward and Brownlee admit that It is very difficult to do statistics with an N of 1.

Jan 14, 2000 Peter D. Ward and Donald Brownlee support the idea that simple life forms are common in the Universe, but contend in Rare Earth that any type of complex, multi-cellular animal life is extremely rare. Their book covers the Rare Earth One of the most popular themes in science fiction is the prevalence of alien intelligent life in the Universe.
Jun 28, 2021 The crux of the Rare Earth Hypothesis seems to be that intelligent life on Earth is rare because we are the end result of a lot of serendipitous Goldilocks-type events.

Rare earth elements are an essential part of many high-tech devices. The U.S. Geological Survey news release Going Critical explains Rare-earth elements (REE) are necessary components of more than 200 products across a wide range of applications, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and
Sep 21, 2008 Despite their name, the rare earths arent actually rare with respect to abundance in the Earths crust. The exception is promethium, a radioactive metal. The CRC Handbook of Chemistry and Physics and IUPAC list the rare earths as consisting of the lanthanides, plus scandium and yttrium.

The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earths
Nov 23, 2021 A group of 17 elements make up a little-known group called rare earth metals. They are notoriously tricky to extract, which is unfortunate since theyre key components in smartphones, batteries, motors, and wind turbines, and essential to a clean-energy future. China has a near monopoly on the mining and processing
May 02, 2019 The rare earth elements (REEs) or rare earth metals (REMs) are a group of metals found within the same ores and possessing similar chemical properties. Scientists and engineers disagree on exactly which element should be included in a list of the rare earths, but they generally include the fifteen lanthanide elements, plus scandium and yttrium.
Jun 22, 2018 The rare earths share many common properties. This makes them difficult to separate or even distinguish from each other. There are very small differences in solubility and complex formation between the rare earths. The rare earth metals naturally occur together in minerals (e.g., monazite is a mixed rare earth phosphate).

Antarctica will experience a total solar eclipse next Saturday, a rare occurrence that will give scientists insight into the behavior of Earths upper atmosphere. Solar eclipses happen when the Moon passes directly between Earth and the Sun, casting its shadow onto Earths surface and blocking out sunlight.

Jun 15, 2019 One of the rare flowers has been historically growing at high altitudes between 300 and 900 m above sea level. The primary reason why the flower is hard to reproduce is because of the uncommon habitat and also some of the other factors that usually favours high altitude. According to the IUCN list, the flower comes in a critically endangered list.

The rare earths are 17 metallic elements, located in the middle of the periodic table (atomic numbers 21, 39, and 5771). These metals have unusual fluorescent, conductive, and magnetic propertieswhich make them very useful when alloyed, or mixed, in small quantities with more common metals such as iron. Geologically speaking, the rare ...
