Definition for the Space words (https://amazing-space.stsci.edu/glossary/#T-Z)

After Glow - a sudden BURST of fireball gamma rays from deep space

Atmosphere - The layer of gases SURROUNDING the surface of a planet, moon, or star.

Axis - An imaginary line through the center of an object. The object ROTATES around this line.

Black Hole - A region of space containing a huge amount of mass compacted into an extremely small volume. A black hole’s gravitational influence is so strong that nothing, not even light, can ESCAPE ITs grasp.

Comet - A ball of rock and ice. A comet’s “signature” long, glowing tail is formed when the Sun’s heat warms the coma or nucleus.

Constellations -A geometric PATTERN of bright stars that appears grouped in the sky.  

Core - The CENTRAL region of a planet, star, or galaxy.

Coronal Holes - Regions in the corona from which the high-speed solar wind is known to originate.  

Craters - A bowl-shaped DEPRESSION caused by a comet or meteorite colliding with the surface of a planet, moon, or asteroid.

Dark Matter - Matter that is too DIM to be detected by telescopes. Dark matter MAKES UP most of the total mass of the universe.

Dwarf - a dwarf planet has NOT cleared away any loose cosmic rubble from its orbit

Field pod View - The area of the sky VISIBLE through a telescope.

Flare - A SUDDEN and VIOLENT outburst of solar energy that is often observed in the vicinity of a sunspot or solar prominence

Galaxy - A COLLECTION of stars, gas, and dust bound together by gravity

Gravity - The attractive FORCE between all masses in the universe

Hemisphere - HALF of a spherical or roughly spherical body

Lunar Eclipse - A DARKENING of the Moon, as viewed from Earth, caused when our planet passes between the Sun and the Moon

Meteor - A BRIGHT STREAK of light in the sky caused when a meteoroid enters the Earth’s atmosphere.  

Milky Way - a spiral galaxy, is the HOME of Earth.

Morphallaxis - REGENERATION by the transformation of existing body tissues.

Nebula - A cloud of gas and dust located between stars and/or surrounding stars. Nebulae are often places where stars FORM

Neutron Star - An extremely COMPACT ball of neutrons created from the central core of a star that collapsed under gravity during a supernova explosion.

(Super) Novas - The EXPLOSIVE death of a massive star whose energy output causes its expanding gases to glow brightly for weeks or months.

Oort Cloud - A vast spherical region in the outer reaches of our solar system where a trillion long-period comets reside.

Planet - An OBJECT that orbits a star. Although smaller than stars, planets are relatively large and shine only by reflected light.

Satellite - A man-made object that orbits Earth, the Moon, or another celestial object.

Singularity -  black hole’s center, where the matter is thought to be infinitely dense, the volume is infinitely small, and the force of gravity is INFINITELY large.
Solar Winds - STREAMS of charged particles flowing from the Sun at millions of kilometers an hour.

Speed of Light - The speed at which light (photons) travels through empty space is roughly 3 * 108 meters per second or 300 million meters per second.

Super Clusters - a CLUSTER of galaxies which themselves occur as clusters.
T-Tauri - A class of very YOUNG, flaring stars on the verge of becoming normal stars fueled by nuclear fusion.

Zeinth -The point on the CELESTIAL sphere that is directly above the observer.
