&#039;&#039;&#039;Hoag&#039;s Object&#039;&#039;&#039; is a non-typical [[galaxy]] of the type known as a [[ring galaxy]].  The appearance of this object has interested amateur astronomers as much as its uncommon structure has fascinated professionals.  The galaxy is [[Galaxies named after people|named]] after [[Arthur Allen Hoag]] who discovered it in [[1950]] and identified it as either a [[planetary nebula]] or a [[peculiar galaxy]].&amp;lt;ref name=&amp;quot;Hoag1950&amp;quot;&amp;gt;{{cite journal&lt;br /&gt;

A nearly perfect ring of young hot blue [[star]]s circle the older yellow nucleus of this ring galaxy ~600 million [[light-year]]s away in the constellation [[Serpens]]. The diameter of the 6″ (seconds of arc) inner core of the galaxy is about 17 ± 0.7 kly (5.3 ± 0.2 kpc) while the surrounding ring has an inner 28″ diameter of 75 ± 3 kly (24.8 ± 1.1 kpc) and an outer 45″ diameter of 121 ± 4 kly (39.9 ± 1.7 kpc), which is slightly larger than the [[Milky Way Galaxy]].&amp;lt;ref name=&amp;quot;OConnelletal1974&amp;quot;&amp;gt;{{cite journal&lt;br /&gt;

}}&amp;lt;/ref&amp;gt;{{Ref_label|A|a|none}} The gap separating the two stellar populations may contain some [[star cluster]]s that are almost too faint to see. As rare as this type of galaxy is, oddly another more distant ring galaxy can be seen, between the nucleus and the outer ring at the 0100 (one o&#039;clock) position.&lt;br /&gt;
&lt;br /&gt;
==History and formation==&lt;br /&gt;
Even though Hoag&#039;s Object was clearly shown on the [[Palomar Star Survey|Palomar &#039;&#039;Star Survey&#039;&#039;]], it was not included in either the &#039;&#039;[[Morphological Catalogue of Galaxies]]&#039;&#039;, the &#039;&#039;[[Catalogue of Galaxies and Clusters of Galaxies]]&#039;&#039;, or the &#039;&#039;[[Catalogue of Galactic Planetary Nebulae]]&#039;&#039;.&amp;lt;ref name=&amp;quot;OConnelletal1974&amp;quot; /&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the initial announcement of his discovery, Art Hoag proposed the hypothesis that the visible ring was a product of [[gravitational lensing]].  This idea was later discarded because the nucleus and the ring have the same [[redshift]], and because more advanced telescopes revealed the knotty structure of the ring, something that would not be visible if the ring were the product of gravitational lensing.&amp;lt;ref name=&amp;quot;Schweizeretal1987&amp;quot;&amp;gt;{{cite journal&lt;br /&gt;

}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Many of the details of the galaxy remain a mystery, foremost of which is how it formed.  So-called &amp;quot;classic&amp;quot; ring galaxies are generally formed by the collision of a small galaxy with a larger disk-shaped galaxy.  This collision produces a density wave in the disk which leads to a characteristic ring-like appearance.  However, there is no sign of any second galaxy that would have acted as the &amp;quot;bullet&amp;quot;, and the core of Hoag&#039;s Object has a very low velocity relative to the ring, making the typical formation hypothesis quite unlikely.&lt;br /&gt;
&lt;br /&gt;
Noah Brosch suggested that Hoag&#039;s Object might be a product of an extreme &amp;quot;bar instability&amp;quot; which occurred a few billion years ago in a [[barred spiral galaxy]].&amp;lt;ref name=&amp;quot;Brosch1985&amp;quot;&amp;gt;{{cite journal&lt;br /&gt;

}}&amp;lt;/ref&amp;gt;&lt;br /&gt;
.  Schweizer, et al. (1987)&amp;lt;ref name=&amp;quot;Schweizeretal1987&amp;quot; /&amp;gt; claim that this is an unlikely hypothesis because the nucleus of the object is spheroidal, whereas the nucleus of a barred spiral galaxy is disc-shaped, among other reasons.  However, they admit evidence is somewhat thin for this particular dispute to be settled satisfactorily.  Interestingly, a few galaxies share the primary characteristics of Hoag&#039;s Object, including a bright detached ring of stars, but their centers are elongated or barred, and they may exhibit some spiral structure.  While none match Hoag&#039;s Object in symmetry, this handful of galaxies are known to some as Hoag-type galaxies.&lt;br /&gt;
&lt;br /&gt;
While there is much still to be explained about the formation of Hoag&#039;s Object, it is suggested that a major &amp;quot;accretion event&amp;quot;, in other words a collision or a capturing of one galaxy by another, caused the formation of the galaxy we see today.  The event likely took place at least 2-3 billion years in the past, and may have resembled the processes that form [[polar-ring galaxy|polar-ring galaxies]].&lt;br /&gt;

[[Image:Beryl09.jpg|thumb|left|250px|Three Beryl Crystals - Aquamarine rough crystal in the center]]&lt;br /&gt;
&#039;&#039;&#039;Aquamarine&#039;&#039;&#039; (Lat. &#039;&#039;aqua marinā&#039;&#039;, &amp;quot;water of the sea&amp;quot;) is a [[gemstone]]-quality transparent variety of [[beryl]], having a delicate blue or [[turquoise]] color, suggestive of the tint of [[seawater]]. It&#039;s closely related to the gem [[emerald]]. Colors vary and yellow beryl ([[heliodor]]), rose pink beryl ([[morganite]]), and white beryl ([[goshenite]]) are known. &lt;br /&gt;
&lt;br /&gt;
==Composition==&lt;br /&gt;
Aquamarine is a beryl with a [[Hexagonal (crystal system)|hexagonal]] [[crystal structure]] and a [[chemical formula]] of Be&amp;lt;sub&amp;gt;3&amp;lt;/sub&amp;gt;Al&amp;lt;sub&amp;gt;2&amp;lt;/sub&amp;gt;Si&amp;lt;sub&amp;gt;6&amp;lt;/sub&amp;gt;O&amp;lt;sub&amp;gt;18&amp;lt;/sub&amp;gt;, a [[beryllium]] [[aluminium]] [[Silicate minerals|silicate mineral]]. It has a [[specific gravity]] of 2.68 to 2.74 and a [[Mohs hardness]] of from 7.5 to 8. Aquamarine typically is on the low end of the specific gravity range, normally at less than 2.7. The pink variety exhibits a high specific gravity of around 2.8. [[Refractive index|Refractive indices]] range around 1.57 to 1.58.&lt;br /&gt;
&lt;br /&gt;
==Locations of deposits==&lt;br /&gt;
It occurs at most localities which yield ordinary beryl, some of the finest coming from [[Russia]]. The gem-gravel [[Placer mining|placer]] deposits of [[Sri Lanka]] contain aquamarine. Clear yellow beryl, such as occurs in [[Brazil]], is sometimes called aquamarine chrysolite. When [[corundum]] presents the bluish tint of typical aquamarine, it is often termed Oriental aquamarine. &lt;br /&gt;
&lt;br /&gt;
In the [[United States]], aquamarines can be found at the summit of [[Mount Antero|Mt. Antero]] in the [[Sawatch Range]] in central [[Colorado]]. In [[Brazil]], there are mines in the states of [[Minas Gerais]], [[Espírito Santo]] and [[Bahia]]. Zambia also produces nice aquamarine as well as Madagascar, Malawi, Tanzania and Kenya.  Much of today&#039;s aquamarine is heated to give it a better color blue. The deeper the blue color, the more valuable the gem is considered.&lt;br /&gt;
&lt;br /&gt;
The biggest aquamarine ever mined was found at the city of Marambaia, Minas Gerais, Brazil, in 1910. It weighed over 110 kg, and its dimensions were 48.5 cm long and 42 cm in diameter.&lt;br /&gt;
&lt;br /&gt;
Aquamarine is the [[List of U.S. state minerals, rocks, stones and gemstones|official state gem]] of Colorado.&lt;br /&gt;
Booby booby boob is what a aquamarine is a boob&lt;br /&gt;
&lt;br /&gt;
==Culture and historical/mythical usage==&lt;br /&gt;
*Aquamarine (along with Bloodstone) is the [[birthstone]] associated with March. It is also the gemstone for the 19th Anniversary.&lt;br /&gt;
*People in the [[Middle Ages]] thought that aquamarine could magically overcome the effects of [[poison]].&lt;br /&gt;
*Ancient sailors traveled with aquamarine crystals, believing that it would ensure a safe passage, and guarantee a safe return; they often slept with the stones under their pillow to ensure sound sleep. They believed the siren’s ([[mermaid]]) fish-like lower body was made of aquamarine.&lt;br /&gt;

&#039;&#039;&#039;[[w:Medicine|Medicine]]&#039;&#039;&#039; is the art and science of the causation, diagnosis and treatment of [[w:disease|disease]] and [[w:injury|injury]]. It is both an &#039;&#039;area of knowledge&#039;&#039; &amp;amp;ndash; a [[w:science|science]] of [[w:body|body]] [[w:organ system|systems]], their diseases and treatment &amp;amp;ndash; and the &#039;&#039;applied practice&#039;&#039; of that knowledge. However, &#039;&#039;medicine&#039;&#039; often refers more specifically to matters dealt with by [[w:physician|physicians]] and [[w:surgery|surgeons]].&lt;br /&gt;
&lt;br /&gt;
The various specialized branches of the science of medicine correspond to the equally specialized medical professions dealing with particular organs or diseases. The science of medicine is the knowledge of body systems and diseases, while the [[w:profession|profession]] of medicine refers to the social structure of the group of people formally trained to apply that knowledge to treat disease.&lt;br /&gt;
&lt;br /&gt;
Medicine comprises various specialities, such as [[w:cardiology|cardiology]], [[w:pulmonology|pulmonology]], [[w:neurology|neurology]], or other fields such as sports medicine, research or public health.&lt;br /&gt;
