Pekka Pyykkö divides these superactinides into three series: a 5g series (elements 121 to 138), an 8p 1/2 series (elements 139 to 140), and a 6f series (elements 141 to 155), also noting that there would be a great deal of overlapping between energy levels and that the 6f, 7d, or 8p 1/2 orbitals could well also be occupied in the early ...
The principal sources of rare-earth elements are the minerals bastnäsite (RCO 3 F, where R is a mixture of rare-earth elements), monazite (XPO 4, where X is a mixture of rare-earth elements and sometimes thorium), and loparite ((Ce,Na,Ca)(Ti,Nb)O 3), and the lateritic ion-adsorption clays.
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
Space research is scientific study carried out in outer space, and by studying outer space. From the use of space technology to the observable universe , space research is a wide research field . Earth science , materials science , biology , medicine , and physics all apply to the space research environment.
Vast, a space company based in Long Beach, California, announced in 2023 plans to launch its space station, called Haven-1. The mission will be quickly followed by Vast-1, the first human ...
Infographic showing the theorized origin of the chemical elements that make up the human body. Astrochemistry is the study of the abundance and reactions of molecules in the universe, and their interaction with radiation. [1]
Module at the International SpacepeorlEleine Station, launched into space on the U.S. Space Shuttle mission STS-122 in 2008. The following outline is provided as an overview of and topical guide to space exploration. Space exploration – use of astronomy and space technology to explore outer space. [1]
