Astronomer: A scientist working in the field of research dealing with celestial bodies, space, and physical space.
carbon dioxide: (or co2) The colorless, odorless gas produced by all animals when oxygen is inhaled reacts with the carbon-rich foods they eat. Carbon dioxide is released when organic matter is burned (including fossil fuels such as oil and gas). On Earth, carbon dioxide functions as a greenhouse gas, trapping heat in the planet’s atmosphere.
Chemicals: A material formed from two or more atoms that integrate (bonds) in fixed proportions and structures. Water, for example, is a chemical created when two hydrogen atoms bond to one oxygen atom. The chemical formula is h2O.
core: Something – usually round shape – in the center of the object. (Geology) The innermost layer of planets such as Earth.
The crust: (in planetary science) the outermost surface of rocky planets, dwarf planets, and natural satellites.
extension: An animal’s intestine or visceral organs, or some non-organism internal material. This term usually applies when these tissues are collected from the body or exposed to onlookers.
exoplanet: Abbreviation for Extosola planet is a planet that orbits stars outside the solar system.
Intestines: An informal term for the gastrointestinal tract, especially the intestine.
host: The act of providing a home or environment for something. For example, a website can host photos, news, or other types of information.
Internal organs: Slang for internal organs such as the stomach and intestines.
iron: A common metal element within the minerals of the Earth’s crust and within its hot core. This metal is also found in space dust and many meteors.
Light year: Distance light travels approximately 9.46 trillion kilometers (approximately 6 trillion miles) per year. To get an idea of this length, imagine a rope long enough to envelop the earth. It is slightly over 40,000 km (24,900 miles). Place it straight. Now, just after the first, we have another 236 million people, the same length, end-to-end. Currently, the total distance is equal to one light year.
link: A connection between two people or things.
magma: Molten rocks beneath the Earth’s crust. When erupted from a volcano, this material is called lava.
magnesium: Metal element number 12 in the periodic table. It burns in white light and is the eighth richest element in the Earth’s crust.
Mantle: (in geology) several other non-uniform planets, such as the outer crust and the thick layers of the Earth. The Earth’s mantle is semi-solid and is generally divided into upper and lower mantles.
mineral: Crystal-forming materials that make up a rock, such as quartz, apatite, or various carbonates. Most rocks contain several different minerals mashed together. Minerals are usually solid and stable at room temperature and have a specific formula or recipe (the atoms occur at a certain percentage) and a specific crystal structure (meaning that atoms are organized in a normal three-dimensional pattern).
Nitric oxide: Chemicals (NOs) involved in many biological functions help to relieve blood vessels and increase blood flow. Also, potentially toxic contaminants released by the combustion of fossil fuels are released or produced by lightning. It cannot play a role in the formation of smog ozone, a powerful lung irritant.
Opaque: Cannot block light and cannot be ignored.
Orbit: The curved path of a celestial object or spacecraft around a galaxy, star, planet, or moon. One complete circuit around the celestial body.
Oxides: A compound created by combining one or more elements with oxygen. Rust is an oxide. The same goes for water.
Peer review: The process of criticizing (in research) by experts in the field who carefully read and criticize the work of peers before being published in a research journal. Peer reviews help to ensure that sloppy science and bad mistakes are not published.
planet: A large celestial object that orbits a star but unlike a star, it does not produce visible light.
spare: An early step or stage that precedes something more important.
silicon: Non-metallic, semiconductor elements used in the creation of electronic circuits. Pure silicon exists as a shapeless powder in the form of shiny, dark gray crystals.
Spectrometer: An instrument that measures the spectrum of light, energy, atomic mass, etc. Typically, chemists use these instruments to measure and report the wavelength of light they observe. The collection, process of data using this instrument, is called spectroscopic measurements, and is useful in identifying elements or molecules present in unknown samples.
Stars: Basic building blocks where galaxies are created. Stars are generated when gravity compresses a cloud of gas. When they get hot enough, the stars emit light, sometimes other forms of electromagnetic radiation. The sun is our closest star.
telescope: A light collection device that usually displays distant objects nearby, due to lens use and the combination of curved mirrors and lenses. However, some people collect radio emissions (energy from different parts of the electromagnetic spectrum) through a network of antennas.
Unique: Something that is different from the others. The only one of that kind.
wavelength: The distance between a series of wave peaks and the next peak, or between one trough and the next trough. It is also one of the “criteria” used to measure radiation.
