Millions of periodic table charts across the world have now become obsolete and the time has come to discard them. The periodic table’s newest elements now have names. The International Union of Pure and Applied Chemistry (IUPAC) has approved new names for four new elements.    Let us meet the newest elements:  The new elements, nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og) got the new name on November 28,  which take slots 113, 115, 117 and 118 respectively on the periodic table.  The new names, proposed in June, underwent five months of public comment and review. IUPAC decided to let the names stand, and unwieldy placeholder names — ununtrium, ununpentium, ununseptium and ununoctium — assigned when the elements were added to the periodic table in December 2015, can now be scrubbed.  Three of the elements were named for the places they were discovered. The name of element 113, “nihonium,” comes from the word “Nihon,” a Japanese word for the country of Japan; element 115 is dubbed “moscovium,” after Moscow; and element 117, tennessine, is named after Tennessee. Element 118, oganesson, honors physicist Yuri Oganessian.

The International Astronomical Union (IAU), arbiter of naming things in space, has prepared an official catalog which has names for 227 stars in our galaxy. As of November 24, names such as Polaris (the North Star) and Betelgeuse (the bright red star in Orion) are approved.  Until now, there has been no central star registry or guidelines for naming. There are many star catalogs, each one designating stars with different combinations of letters and numbers. Thesw excess options has left most stars with an abundance of labels (HD 8890 is one of over 40 designations for Polaris).  The new IAU catalog is a stab at formalizing the more popular names. Before this, only 14 stars (included in the 227) had been formally named. The brightest member of Alpha Centauri, the pair of stars that are among the closest to our solar system, is now officially dubbed Rigil Kentaurus, an early Arabic name meaning “foot of the centaur
