Galaksi berbentuk spiral, NGC 4535. Letaknya berada di konstelasi Virgo dan jaraknya sekitar 54 juta tahun cahaya dari bumi
English: This image depicts the galaxy NGC 4535, in the constellation of Virgo (The Maiden), on a beautiful background full of many distant faint galaxies. Its almost circular appearance shows that we observe it nearly face-on. In the centre of the galaxy, there is a well-defined bar structure, with dust lanes that curve sharply before the spiral arms break from the ends of the bar. The bluish colour of the spiral arms points to the presence of a large number of hot young stars. In the centre, however, older and cooler stars give the bulge of the galaxy a yellower appearance. This visible image was made with the FORS1 instrument on ESO’s 8.2-metre Very Large Telescope. The galaxy can also be seen through smaller amateur telescopes, and was first observed by William Herschel in 1785. When seen through a smaller telescope, NGC 4535 has a hazy, ghostly appearance, which inspired the prominent amateur astronomer Leland S. Copeland to name it “The Lost Galaxy” in the 1950s. NGC 4535 is one of the largest galaxies in the Virgo Cluster, a massive cluster of as many as 2000 galaxies, about 50 million light-years away. Although the Virgo Cluster is not much larger in diameter than the Local Group — the galaxy cluster to which the Milky Way belongs — it contains almost fifty times as many galaxies.

Platinum mass & well-formed crystals from Russia. (public display, Carnegie Museum of Natural History, Pittsburgh, Pennsylvania, USA) A mineral is a naturally-occurring, solid, inorganic, crystalline substrance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 4900 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates. Elements are fundamental substances of matter - matter that is composed of the same types of atoms. At present, 118 elements are known (four of them are still unnamed). Of these, 98 occur naturally on Earth (hydrogen to californium). Most of these occur in rocks & minerals, although some occur in very small, trace amounts. Only some elements occur in their native elemental state as minerals. To find a native element in nature, it must be relatively non-reactive and there must be some concentration process. Metallic, semimetallic (metalloid), and nonmetallic elements are known in their native state as minerals. Platinum (Pt) is far more valuable that gold, but it doesn't have a distinctive, prestigious color. Like most metals, platinum has a silvery color. Platinum, when purified, is heavier than gold, but specimen platinum has about the same specific gravity as gold nuggets (about 19). Platinum is alway found significantly alloyed with other elements, usually other PGEs (platinum-group elements: platinum (Pt), palladium (Pd), osmium (Os), iridium (Ir), rhenium (Re), rhodium (Rh), ruthenium (Ru)). Platinum is typically found in Precambrian ultramafic igneous rocks, but there are also some Pt-bearing placer deposits in Canada, Colombia, and Russia.
