Honors Earth 2011 Emma Hopkins Ch.24 Quiz

object in space?	term guess	hint
no		the study of the universe
no		the magnitude of a given if it were situated at a distance of 10 parces (32.6 light years) from the earth
no		the distance light travels in one year
no		the model that most accurately describes the birth and current state of the universe
yes		matter that has accumulated in space in large 'clumps' or 'strands'
yes		also known as interstellar matter
yes		when nebulae are in close proximity to very hot (blue) stars, and glow
yes		clouds of interstellar material are too far from bright stars to to be illuminated
yes		glowing clouds of hydrogen gas
yes		large debris and grains of carbon compounds that reflect the light of nearby stars
no		A graph in which the absolute magnitude (intrinsic luminosity) of stars is plotted vertically against their surface temperatures (or corresponding spectral types).
yes		90% of stars fall along this band that runs from the upper right hand corner to the lower left hand corner of the hertzsprung-russell diagram
yes		very luminous stars also called giants
no		a nuclear reaction in which hydrogen nuclei are fused into helium

object in space?	term guess	hint
yes		stars which alternately expand and contract, never reaching equilibrium
yes		brilliant explosions in which stars terminate
yes		what remains when low and medium mass stars collapse
no		short pulses of radio energy
yes		a theoretical massive object, formed at the beginning of the universe or by the gravitational collapse of a star exploding as a supernova
yes		flat, disk-like objects that range from 20,000 to 125,000 light years in diameters
yes		A spiral galaxy with a barlike bulge in the center, extending between the core and the spiral arms
yes		galaxies with ellipsodal shapes that can be nearly spherical, and they lack spiral arms
yes		the smallest type of galaxy
yes		a galaxy showing no symmetry
yes		galaxies grouped into gravatationally bound clusters
yes		the large group of more than 35 galaxies which includes our Milky Way
no		A graph in which the absolute magnitude (intrinsic luminosity) of stars is plotted vertically against their surface temperatures (or corresponding spectral types)
yes		Hypothetical form of matter invisible to electromagnetic radiation, postulated to account for gravitational forces observed in the universe
