astronomer: Scientists engaged in research fields that deal with celestial bodies, space, and the physical universe.
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.
brown dwarf: A star wannabe who never became large enough to sustain nuclear fusion.
Celestial body: An object of considerable size that formed naturally in space. Examples include comets, asteroids, planets, moons, stars, galaxies, etc.
chemicals: A substance formed when two or more atoms combine in a certain proportion and structure. For example, water is a chemical produced when two hydrogen atoms combine with one oxygen atom. Its chemical formula is H2O. Chemistry can also be used as an adjective to describe the properties of materials that result from various reactions between different compounds.
cloud: A plume of molecules or particles, such as water droplets, that moves under the action of external forces such as wind, radiation, or water currents.
colleague: A person who works with other people. colleagues and team members.
constellation: A pattern formed by prominent stars lined up in the night sky. Modern astronomers divide the sky into 88 constellations, 12 of which (known as the zodiac) lie along the sun’s path through the sky over the course of a year. Cancer, the original Greek name for the constellation Cancer, is one of the 12 zodiacal constellations.
disk: A round, flat, and usually fairly thin object. (in astronomy) a rotating cloud-like collection of gas, dust, or both from which planets may form. Or the structure of certain large rotating bodies in the universe, including spiral galaxies.
environment: The sum of everything that exists around an organism, or the processes and conditions that those things create. Environment can also refer to the weather or ecosystem in which an animal lives, or the temperature and humidity (or the placement of objects near the item of interest).
fuse: (v.) To join two things together, often along a seam. (n.) Cord, tubing, or other material that can burn and ultimately ignite an explosive. or an electrical device that interrupts an electrical circuit when it overheats, preventing the wires from becoming hot enough to cause a fire.
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.
helium: The lightest inert gas in the noble gas series. Helium can become solid at -272 degrees Celsius (-458 degrees Fahrenheit).
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.
insight: The ability to accurately and deeply understand a situation simply by thinking, rather than deriving solutions through experimentation.
journal: (in science) a publication in which scientists share their research results with experts (and sometimes the public). Some journals publish papers in all areas of science, technology, engineering, and mathematics, while others specialize in a single subject. Peer-reviewed journals are the most important criterion. All submitted papers are sent to external experts for reading and critique. The goal here is to prevent the publication of mistakes, fraud, or works that are not novel or convincingly demonstrated.
Jupiter: (in astronomy) The largest planet in the solar system and the shortest day (9 hours and 55 minutes). It is a gas giant and its low density indicates that it is composed primarily of the light elements hydrogen and helium. The planet also gives off more heat than it receives from the Sun, as its mass is compressed by gravity (and the planet slowly shrinks).
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.
month: Natural satellites of all planets.
planet: A large celestial body that orbits a star, but unlike a star, it does not produce visible light.
pressure: Force applied uniformly over the entire surface. It is measured as force per unit area.
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.
star’s: An adjective meaning or relating to a star.
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. Systems can also apply to processes and ideas that are part of a method or ordered sequence of steps for completing a task.
