Tenebrarum et nebulae, Regis regum rectissimi. Diesque mirabilium Tonitruorum fortium, Dies quoque angustiae, Maeroris ac tristitiae. Regis regum rectissimi. In quo cessabit mulierum Amor et desiderium, Nominumque contentio Mundi hujus et cupido. Regis regum rectissimi prope est dies domini. King of kings and of lords most high, Comes his day ...
Chondrules in the chondrite classification Grassland. A millimeter scale is shown. Chondrules in the Carbonaceous Chondrite NWA 13887. A chondrule (from Ancient Greek χόνδρος chondros, grain) is a round grain found in a chondrite. Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids.
There are many indicators why some achondrites are deemed primitive. Some contain relic chondrules (e.g. Acapulcoite, Lodranite) and some have oxygen isotope ratios that are similar to chondrites. There are similarities in trace element concentrations between primitive achondrites and chondrites.
The main petrologic characteristic of Type 1 chondrites, such as CIs, is the lack of recognizable chondrules, thus excepting the sample from Tagish Lake. Yet small chondrule fragments and calcium–aluminium-rich inclusions (CAIs) do occur, but are quite rare.
[1] [4] Entries in the catalogue are designated with a "C" and the catalogue number (1 to 109). Unlike objects in the Messier catalogue, which are listed roughly in the order of discovery by Messier and his colleagues, [ 5 ] the Caldwell catalogue is ordered by declination , with C1 being the most northerly and C109 being the most southerly ...
[1] In the second release, some coordinates for southern hemisphere regions have an uncertainty over 1 minute of arc. [1] This can make them difficult to find, so a revised catalog called BFS (Blitz, Fich and Stark) was released [1] with 65 new regions and about 20 removals. [1] Most of the removed items were the aforementioned nebula or ...
In astronomy, Bok globules are isolated and relatively small dark nebulae containing dense cosmic dust and gas from which star formation may take place. Bok globules are found within H II regions, and typically have a mass of about two [1] to 50 solar masses contained within a region about a light year or so across (about 4.5 × 10 47 m 3). [2]
The Oxyrhynchus hymn (or P. Oxy. XV 1786) is the earliest known manuscript of a Christian Greek hymn to contain both lyrics and musical notation. The papyrus on which the hymn was written dates from around the end of the 3rd century AD. [1] It is on Papyrus 1786 of the Oxyrhynchus papyri, now kept at the Papyrology Rooms of the Sackler Library ...
