asteroid: A rocky object that orbits around the sun. Most asteroids orbit the region between the orbits of Mars and Jupiter. Astronomers call this region the asteroid belt.
astrophysicist: A scientist who works in the field of astronomy, which deals with understanding the physical properties of stars and other celestial objects in the universe.
atom: Basic unit of chemical elements. Atoms consist of a dense nucleus containing positively charged protons and uncharged neutrons. The nucleus of an atom is orbited by a cloud of negatively charged electrons.
black hole: A region of space with a gravitational field so strong that no matter or radiation (including light) can escape.
heavenly: (in astronomy) of or relating to the sky or outer space.
colleague: A person who works with other people. colleagues and team members.
cosmologist: A scientist who studies the origin and development of the universe.
cosmos: (adjective: universe) A term referring to the universe and everything in it.
dark matter: A physical object or particle that does not emit detectable radiation. They are thought to exist because of the unexplained gravitational force they appear to exert on other visible celestial bodies.
fluctuation: (v. fluctuate) Some kind of change in a pattern or signal that changes at irregular intervals and often by amounts that are difficult to predict.
gravity: A force that attracts something with mass or volume to another thing with mass. The greater the mass of something, the greater its gravitational force.
hydrogen:The lightest element in the universe. As a gas, it is colorless, odorless, and highly flammable. It is an essential part of many of the fuels, fats, and chemicals that make up living tissues. It consists of a single proton (acting as the atomic nucleus) orbited by a single electron.
Mars: The fourth planet from the Sun, and the only planet removed from Earth. Like Earth, it has seasons and humidity. However, its diameter is only about half that of Earth.
mass: A number that indicates how much an object resists acceleration and deceleration. Basically, it is a measure of how much material an object is made of.
Case: Something that occupies space and has mass. All substances on Earth have a property called “weight.”
model: A simulation (usually using a computer) of a real-world event developed to predict one or more possible outcomes. Or an individual whose purpose is to show how something works or looks to another person.
orbit: The curved path of a celestial body or spacecraft around a galaxy, star, planet, or moon. A complete orbit around a celestial body.
particle: A trace amount of something.
physical: (adjective) A term used to describe something that exists in the real world rather than in memory or imagination. It can also refer to properties of a material due to size or non-chemical interactions (such as when one block collides with another block with force). (In biology and medicine) This term can refer to the body, such as a physical exam or physical activity.
physicist: A scientist who studies the nature and properties of matter and energy.
planet: A large celestial body that orbits a star, but unlike a star, it does not produce visible light.
primitive: an adjective that refers to something that dates back to the beginning of time or the earliest existence of something.
quantum: (pl. quanta) A term referring to the smallest amount of anything, especially energy or particle mass.
real time: A term meaning immediacy. Something is being researched, recorded, and/or reported at the exact moment it is happening.
satellite: A moon orbiting a planet, or a vehicle or other manufactured object orbiting a celestial body in space.
solar system: The eight major planets and their moons that orbit the sun, as well as smaller celestial bodies in the form of dwarf planets, asteroids, meteoroids, and comets.
solar wind: A stream of charged particles (including atomic nuclei) emitted from the surface of a star such as the Sun. It has the potential to penetrate the solar system. When emitted by a star other than the Sun, this radiation is known as a stellar wind.
star: The basic building blocks that make up galaxies. Stars develop when clouds of gas are compressed by gravity. When a star gets hot enough, it emits light and sometimes other forms of electromagnetic radiation. The sun is the closest star to us.
subatomic: Something smaller than an atom. The smallest substance that has all the properties of chemical elements (hydrogen, iron, calcium, etc.).
solar: The star at the center of Earth’s solar system. It is located approximately 27,000 light years from the center of the Milky Way galaxy. It is also a word that refers to a star like the sun.
system: A network of parts that work together to accomplish some function. For example, blood, blood vessels, and the heart are the main components of the human body’s circulatory system. Similarly, trains, platforms, tracks, road signals, and elevated tracks are among the potential components of a country’s railway system. A system can also apply to a process or idea that is part of some method or ordered set of steps for completing a task.
technology: The application of scientific knowledge for practical purposes, especially in industry, or the devices, processes, and systems resulting from such efforts.
universe: The entire universe: Everything that exists beyond time and space. It has been expanding ever since it formed during an event known as the Big Bang about 13.8 billion years ago (which may take hundreds of millions of years or more).
