The nearest star system to our Solar System, Alpha Centaurus is reverting to its old name Rigil Kentaurus, which means “foot of the centaur” in Arabic. Let me admit, I had become attached to the name Alpha Centaurus hence this new (old by the way) is difficult to swallow.
Alpha Centaurus ( OK, Rigil Kentaurus) is 4.3 light-years away from the earth. A light-year is the distance travelled by light in one year.
The periodic table now has new elements. Read the following article below for greater insights:
Last December, four new elements—with atomic numbers 113, 115, 117, and 118—earned their spots on the periodic table. They were temporarily named ununtrium, ununpentium, ununseptium, and ununoctium until the International Union of Pure and Applied Chemistry revealed their “unofficial” names in June. Now that the period for public comment is over,those names arefinally official,The New York Times reports. Three of the elements were named after locations of scientists’ institutions: Tennessine (Tennessee), Nihonium (Japan) and Moscovium (Moscow). Yuri Oganessian, a nuclear physics professor at the Joint Institute for Nuclear Research, inspired the fourth, Oganesson. The four elements, synthetically created in labs, round out the seventh row of the table.
