Since we are in a new generation, we can hear a lot of new terminologies or words in social media. In connection with it, today’s technology is quickly improving and is the reason why you always see and hear some astronomy terminologies, especially when it comes to scientific discoveries.
Now let us know first the meaning of the word “astronomy.”
Astronomy – is the study of the sun, moon, stars, planets, comets, gas, galaxies, gas, dust and other non-Earthly bodies and phenomena.
Here are some of the words regarding astronomy.
asteroid – a small rocky body orbiting the sun.
astronaut – a person who is trained to travel in a spacecraft.
astronomer – a scientist who studies the stars, planets, and other natural objects in space.
atmosphere – a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body.
black hole – a region of space having a gravitational field so intense that no matter or radiation can escape.
bolometer – a sensitive electrical instrument for measuring radiant energy.
celestial – primarily used to describe things that have to do with the heavens such as angels, spirits, stars, and planets.
comet – a celestial object consisting of a nucleus of ice and dust and, when near the sun, a “tail” of gas and dust particles pointing away from the sun.
constellation – a group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure.
cosmology – the science of the origin and development of the universe.
cosmonaut – a Russian astronaut.
cosmos – the sum total of everything — pretty big.
dwarf planet – a celestial body that is in orbit around the Sun and is not a satellite.
eclipse – most often used to describe either a solar eclipse, when the Moon’s shadow crosses the Earth’s surface or a lunar eclipse, when the Moon moves into the Earth’s shadow.
equinox – commonly regarded as the moment the plane (extended indefinitely in all directions) of Earth’s equator passes through the center of the Sun, which occurs twice each year, around 20 March and 22-23 September.
exoplanet – a planet that orbits a star outside the solar system.
galaxy – a system of millions or billions of stars, together with gas and dust, held together by gravitational attraction.
heliocentric – the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System.
hydrogen – a colorless, odorless, highly flammable gas, the chemical element of atomic number 1.
helium – the chemical element of atomic number 2, an inert gas that is the lightest member of the noble gas series.
light-year – a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 trillion miles).
lunar – used to describe something that is related to the moon.
meteorite – a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
meteoroid – a small rocky or metallic body in outer space.
Milky Way – the galaxy that contains our Solar System.
NASA – defined as an acronym for the National Aeronautics and Space Administration, the federal agency that is responsible for aerospace research, aeronautics, and the civilian space program.
nebula – an interstellar cloud of dust, hydrogen, helium and other ionized gases. A name for any diffuse astronomical object, including galaxies beyond the Milky Way.
neutron star – the collapsed core of a large star which before collapse had a total of between 10 and 29 solar masses.
satellite – an artificial body placed in orbit around the earth or moon or another planet in order to collect information or for communication.
solar system – the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.
solstice – either of the two times in the year, the summer solstice and the winter solstice, when the sun reaches its highest or lowest point in the sky at noon, marked by the longest and shortest days.
spectrum – a band of colors, as seen in a rainbow, produced by separation of the components of light by their different degrees of refraction according to wavelength.
supernova – a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass.
total eclipse – an eclipse in which the whole of the disk of the sun or moon is obscured.
universe – all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.
