Can anyone make me vocabulary list of 30 words on Astronomy and explain the meaning of each word?

Answer 1

A vocabulary lost of 30 words on astronomy would include the basic words plus a few that are very specialized. These words could be: star, sun, planet, moon, comet, asteroid, meteor, meteorite, nova, nebula, black hole, gas giant, crater, vacuum, orbit, rings, supernova, shooting star, gamma rays, cosmic, radiation, sunspots, solar flare, celestial, galaxy, universe, stellar, dwarf, clusters, and spiral galaxy.

Answer 2

1. Absolute magnitude. Magnitude that a star would appear to have if it were at a distance of 10 PC from the Sun.
2. altitude a. distance above the surface of a planet, used in describing an atmosphere or a spacecraft orbit. b. Angle of elevation above the horizon, for the line of sight to a celestial object.
3. Astrology. A system in which the positions of the Sun, Moon, and Planets are supposed to exert an influence on events on Earth. Originally a part of astronomy, Astrology is today without scientific content. Astrology is strictly forbidden in The Bible.
4. Binary star. Double star with the two stars in orbit around one another.
5. Celestial Equator. Great circle formed on the celestial sphere by the extension out of the Earth's equatorial plane.
6. Cluster. A group of apparently near by objects; clusters of stars or galaxies. Star clusters are open or globular. Good examples of an open cluster is M45, The Pleiades in Taurus and the Hyades also in Taurus. A good example of a globular cluster is M44, Praesepe or "Beehive" cluster in Cancer.
7. Constellation. A group of stars that seemed to suggest the shape of some god, person, animal or object. Now a term used to designate a region of the sky. There are 88 constellations.
8. Core. Central region of a planet. The Earth's core is liquid, possible with a small, solid inner core.
9. Density. A measure of compactness: mass of an object divided by its volume.
10. Eclipse. Blocking of light from one body by another that passes in front of it. Eclipse can be total or partial.
11. Emission spectrum. Spectrum that consists of emission lines.
12. Full moon. Observed once each month, when the Earth lies between the Sun and Moon, and the fully illuminated disk of the Moon can be seen.
13. Galactic equator. Central plane of the Milky Way galaxy.
14. Galaxy. Large number of stars with their interstellar gas and dust, grouped into a region that is well separated from other galaxies. (Star clusters occur on scale much smaller than that of galaxies).
15. Galilean satellites. Four satellites of Jupiter discovered by Galileo who first named them Medicean satellites, after Cosimo de Medci, his patron.
16. Gibbous Moon. Phase of the Moon during which more that half of the disk appears illuminated.
17. Halo ( of galaxy). Region of a spiral galaxy that extends away from the flattened disk, and contains few stars, some globular clusters, making a roughly spherical overall shape for the galaxy.
18. Irregular galaxy. Galaxy that has no symmetrical or spiral shape.
19. Latitude. Coordinate used to measure (in degrees) the angular distance of a point or celestial objects above or below an equator.
20. Light year. Distance that light travels in 1 year.
21. Longitude. Coordinate used to specify the position of a point or direction around (or parallel to) an equator.
22. Magnitude. Scale for describing brightness of a celestial object. See apparent magnitude, absolute magnitude.
23. Meteor. Glowing trail in the upper atmosphere, produced by meteoroid burning up as it moves at high speed.
24. Milky Way. Bright band that stretches across the sky, produced by large number of stars and other bright objects that lie near the equatorial plane of our galaxy.
25. New moon. Phase of the moon when its motion brings it between the Earth and Sun, and thus appears to us not to be illuminated.
26. Nova. Abbreviation from nova Stella. Latin for new star, literally meaning the sudden appearance of a star where none had previously been known. Term now applied to sudden large brightening of a star, followed by a less rapid decrease in brightness.
27. Orbit. Path traced out by one object around another.
28. Satellite. Body that revolves in orbit around another body. Planets are satellites of the Sun, the Moon is a satellite of the Earth, and artificial satellites have been sent into orbit around the Earth, Moon, Mars and Venus.
29. Solar wind. Flow of high-speed electrically charged particles form the solar corona, outward through the solar system.
30. Zodiac. Band on the sky, centered on the ecliptic, and about 18 degrees wide, through which the Sun, Moon and planets appear to move through the course of each year.

This is the link i got it from. It'll be real useful to you, i believe. =)
