Occultation

An occultation is an event that occurs when one object is hidden from the observer by another object that passes between them. The term is often used in astronomy, but can also refer to any situation in which an object in the foreground blocks from view (occults) an object in the background. In this general sense, occultation applies to the visual scene observed from low-flying aircraft (or computer-generated imagery) when foreground objects obscure distant objects dynamically, as the scene changes over time.

If the closer body does not entirely conceal the farther one, the event is called a transit. Both transit and occultation may be referred to generally as occlusion; and if a shadow is cast onto the observer, it is called an eclipse.

The symbol for an occultation, and especially a solar eclipse, is (U+1F775 🝵).

Examples of use of Occultation

1. Radio occultation experiments have been a staple of unmanned missions to other planets ever since.

2. Imam Mohammad al–Mahdi, the last of 12 Shiite holy figures or imams, is believed to have gone into occultation near what is now the Iraqi city of Samarra.

3. Scientists first used the approach, known as radio occultation, to study Mars‘s atmosphere in 1'65 with the Mariner 4 spacecraft, notes Thomas Yunck, who helped pioneer the technique for terrestrial work at NASA‘s Jet Propulsion Laboratory in Pasadena, Calif.

4. Abul–Qassem Mohammed, the 12th leader whom Shia Muslims regard as a successor to the prophet Mohammed, entered "occultation" in '41 and will one day return to rule justly before Judgment Day.

5. Since the 12th Imam is in "grand occultation", thus not exercising power on a day–to–day basis, the task devolves to "chosen ones from the family of the Prophet". In the case of Iran today it means Ayatollah Ali Khamenei, the "Supreme Guide" who claims to be a descendant of Hussain, the third Imam.
