Anyone with access to a DSLR camera and a tripod (or a steady surface) can take stunning photos of the night sky with all its glorious stars. You will even start to see some Nebulae, Galaxies, Globular Clusters, the Milky Way, Meteorites, Auroras, and more. If you own a point-and-sh...
Some form below Earth's surface. Some form on or above Earth's surface. We describe these two basic types: Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are: diabase, ...
Gold prospectors learned that gold could be found in areas where these green rocks were present. This is because mariposite is an ore of gold.Quartzite is a non-foliated metamorphic rock that is produced by the metamorphism of sandstone. It is composed primarily of quartz. The specimen above...
which is silicon dioxide) is chemically reduced to elemental silicon at high temperatures, yielding molten silicon which is then allowed to cool and solidify. This piece was from the top of the container so it shows one kind of surface on the top and quite a different ...
other minerals commonly found in meteorites, and not at all like typical Earth rocks, so they are definitely part of the asteroid. Final release of the analysis of the grains is expected to take place in 2012.Note: Often, images posted on this site are slightly altered to enhance their ...
Silicon crystallizes into a four-sided cubic structure, which can be seen in the crease lines on the tops of silicon boules, which always have four creases. This one has nine. That is utterly inexplicable to me. Source: Andrew Goodall Contributor: Andrew Goodall Acquired: 8 April, 2009 Text...
Magnetite thermite is said to burn hotter than red rust thermite, but both work. The fun thing about magnetite is that you can find it lying around any beaches in many parts of the country. I collected about 40 pounds on Ocean Beach in San Francisco, in less than half an hour using a...
Antarctica is a very good place to study meteorites. They are easy to find against the white snow and ice. The ice also keeps them well preserved. Antarctica Video The video below gives you a good idea of what Antarctica is like.
Krypton is a gaseous chemical element that exists in concentrations of about one part per million in the Earth's atmosphere. Since it exists in low concentrations, it is difficult and expensive to extract, making it rather expensive when it reaches the market. Its most common use is in lighti...
Carbon is a building block of a living organism and a diamond is made of carbon. Meteorites containing diamonds are in museums. Does that mean that life exists other than on earth? Byanon20096— On Oct 25, 2008 why does carbon contribute to pollution?
