Strontium is named after the Scottish village of Strontian (Scottish Gaelic: Sròn an t-Sìthein), where it was discovered in the ores of the lead mines. [ 27 ] In 1790, Adair Crawford , a physician engaged in the preparation of barium, and his colleague William Cruickshank , recognised that the Strontian ores exhibited properties that differed ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The ideal formula of strontianite is SrCO 3, with molar mass 147.63 g, [4] but calcium (Ca) can substitute for up to 27% of the strontium (Sr) cations, and barium (Ba) up to 3.3%. [2] The mineral was named in 1791 for the locality, Strontian, Argyllshire, Scotland, where the element strontium had been discovered the previous year. [2]
In the hills to the north of Strontian lead was mined in the 18th century and in these mines the mineral strontianite was discovered, from which the element strontium was first isolated. The village name in Gaelic , Sròn an t-Sìthein , translates as the nose [i.e. 'point'] of the fairy hill , meaning a knoll or low round hill inhabited by the ...
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 ...
Dubnium and Moscovium were named after Russia's Dubna [23] and Moscow cities. Several places in Scandinavia have elements named after them. Yttrium, terbium, erbium, and ytterbium are all named for the Swedish village of Ytterby, where their ores were first found. [24] Hafnium is named after Hafnia, the Latin name for Danish capital Copenhagen ...
Berzelius and Hisinger discovered the element in ceria and named it after the newly discovered asteroid (then considered a planet), Ceres. Klaproth discovered it simultaneously and independently in some tantalum samples. Mosander proved later that the samples of all three researchers had at least another element in them, lanthanum.

Scientists recently discovered that the merger and collapse of two neutron stars makes an almost perfectly spherical explosion.
