In Orthodox Christian iconography, the Star of Bethlehem is often depicted not as golden, but as a dark aureola, a semicircle at the top of the icon, indicating the Uncreated Light of Divine grace, with a ray pointing to "the place where the young child lay" (Matthew 2:9).

[3] Its magnetic field is the strongest in the Solar System after the Sun's. [25], Using the chondritic reference model and combining known compositions of the crust and mantle, the unknown component, the composition of the inner and outer core, can be determined: 85% Fe, 5% Ni, 0.9% Cr, 0.25% Co, and all other refractory metals at very low concentration. padding: 0 1px 0 5px; Enhancing health-care expenditure to mitigate negative health effects of environmental damage is often promoted by health-care practitioners. .section1 { "Westward leading" Description of when Jupiter and Venus aligned. } 5They told him, "In Bethlehem of Judea; for so it is written by the prophet: 6'And you, O Bethlehem, in the land of Judah, [37][38] Origen, one of the most influential early Christian theologians, connected this prophecy with the Star of Bethlehem: If, then, at the commencement of new dynasties, or on the occasion of other important events, there arises a comet so called, or any similar celestial body, why should it be matter of wonder that at the birth of Him who was to introduce a new doctrine to the human race, and to make known His teaching not only to Jews, but also to Greeks, and to many of the barbarous nations besides, a star should have arisen? [33] Mercury has a solid silicate crust and mantle overlying a solid iron sulfide outer core layer, followed by a deeper liquid core layer, and then a possible solid inner core making a third layer. } [48][49] Archaeologist and Assyriologist Simo Parpola has also suggested this explanation. 2020 Feb 1;395(10221):338. doi: 10.1016/S0140-6736(20)30144-6. Lancet. [26] Earth's core is depleted in germanium and gallium. [15] This is believed to be because differentiation of the core is directly related to a body's initial heat, so Mercury's core is relatively large and active. The framework is based on scientific evidence that human It was also recorded in Korea: "In the fifty-fourth year of Hyokkose Wang, in the spring, second month, day chi-yu, a po-hsing appeared at Hoku" (Samguk Sagi, The Historical Record of the Three Kingdoms). In-space propulsion begins where the upper stage of the launch vehicle leaves off; performing the functions of primary propulsion, reaction control, station keeping, precision pointing, and orbital maneuvering.The main engines used in space provide the primary propulsive force for orbit transfer, planetary trajectories and extra planetary landing and ascent. [26] Sulfur, carbon, and phosphorus only account for ~2.5% of the light element component/mass deficit. } It emphasizes a plant-forward diet where whole grains, fruits, vegetables, nuts and legumes comprise a greater proportion of foods consumed. [19] The properties of these metallic hydrogen layers is a major area of contention because it is difficult to produce in laboratory settings, due to the high pressures needed. [3], A planetary core acts as a heat source for the outer layers of a planet. } color:#ffffff; [12] The involvement of astrologers in the story of the birth of Jesus was problematic for the early Church, because they condemned astrology as demonic; a widely cited explanation was that of Tertullian, who suggested that astrology was allowed 'only until the time of the Gospel'. Interview with Rick Larson. [17] Conservation of energy calculations as well as magnetic field measurements can also constrain composition, and surface geology of the planets can characterize differentiation of the body since its accretion. } 2019 Feb 2;393(10170):386-387. doi: 10.1016/S0140-6736(18)33179-9.

[79] In Hebrew Jupiter is called Sedeq, meaning "righteousness", a term also used for the Messiah, and suggested that because the planet Venus represents love and fertility, so Chester had suggested astrologers would have viewed the close conjunction of Jupiter and Venus as indicating a coming new king of Israel, and Herod would have taken them seriously. Healthy diets and sustainable food systems. [27] The core contains half the Earth's vanadium and chromium, and may contain considerable niobium and tantalum. [28], Pallasites are thought to form at the core-mantle boundary of an early planetesimal, although a recent hypothesis suggests that they are impact-generated mixtures of core and mantle materials. In the tapestry of the subject designed by Edward Burne-Jones (and in the related watercolour), the star is held by an angel. } Copyright 2022 Elsevier Inc. except certain content provided by third parties. In the Earth, the heat flux over the core mantle boundary is 12 terawatts. From here gravity takes over to produce Moon to Mars sized planetary embryos (105 106 years) and these develop into planetary bodies over an additional 10100 million years.[21]. ul.underline-links li a:hover, ol.underline-links li a:hover { [28][29] Aspects of Matthew's account which have raised questions of the historical event include: Matthew is the only one of the four gospels which mentions either the Star of Bethlehem or the Magi.

[26], Sulfur is strongly siderophilic and only moderately volatile and depleted in the silicate earth; thus may account for 1.9 weight% of Earth's core. [40], While Origen argued for a naturalistic explanation, John Chrysostom viewed the star as purely miraculous: "How then, tell me, did the star point out a spot so confined, just the space of a manger and shed, unless it left that height and came down, and stood over the very head of the young child?
