Mercury was found in Egyptian tombs that date from 1500 BC; [32] cinnabar, ... Alchemists thought of mercury as the First Matter from which all metals were formed.
Mercury is the first planet from the Sun and the smallest in the ... The first MESSENGER, which ended in 2015, found higher-than-expected potassium and sulfur levels ...
It then passed close to Mercury on March 29, 1974, as it flew towards the Sun. This was the first observation made of Mercury at close range. After the encounter Mariner 10 was in an orbit around the Sun such that for every one of its orbits Mercury made two, and the spacecraft and the planet would be able to meet again. This allowed the probe ...
Galileo [9] [10] discovered the Galilean moons. These satellites were the first celestial objects that were confirmed to orbit an object other than the Sun or Earth. Galileo saw Io and Europa as a single point of light on 7 January 1610; they were seen as separate bodies the following night. [11] Callisto: Jupiter IV o: 8 January 1610 p: 13 ...
Mercury retrograde refers to the period of time when Mercury moves slower than the Earth around the sun – causing it to appear to spin backward in the night sky.
The first elemental metal with a clearly identifiable discoverer is cobalt, discovered in 1735 by Georg Brandt, by which time the Scientific Revolution was in full swing. [6] (Even then, cobalt might have been prepared before the 13th century by alchemists roasting and reducing its ore, but,in any case, its distinct nature was not recognised.) [7]
Archaeologists have unearthed a 2,000-year-old clay head that once belonged to a Roman figurine of the god Mercury. The unusual find provides new context about life in Roman Britain.
The two discovered a new element in a molybdenum sample that was used in a cyclotron, the first element to be discovered by synthesis. It had been predicted by Mendeleev in 1871 as eka-manganese. [171] [172] [173] In 1952, Paul W. Merrill found its spectral lines in S-type red giants. [174]
