Relationships in the Universe
This is the estimated number of galaxies in the universe, and the approximate number of stars found in each galaxy.
What is billions?
This is the star property that depends on the distance from Earth.
What is apparent magnitude?
This feature of the Sun’s structure is where energy is first radiated out of.
What is the core?
This is the most complex organization of an animal's body. (Think cells, organs, etc.)
What is an organism?
Even though light travels at about 300,000 kilometers per second, it takes over 4 years for light from the nearest star (other than the Sun) to reach Earth. This unit of measurement helps scientists describe that distance.
What is a light-year?
This is the star property that affects a star's color.
What is temperature?
This phenomenon occurs when heated gases in the Sun’s interior rise toward the surface and cooler gases sink, creating a cycle.
What is convection?
This is the least complex organization in an animal's body. (Think cells, tissues, etc.)
What is an atom?
This is the definition of the light-year.
What is the distance light travels in one year?
Even if a star appears dim from Earth, it may still be extremely bright if it has high _________.
What is absolute brightness?
These dark, cooler areas on the Sun's surface are caused by strong magnetic fields and appear in cycles.
What are sunspots?
This is a single-celled organism that can be plant-like or animal-like.
What is a protist?
This is the shape of the Milky Way.
What is spiral?
This is the actual measure of how bright a star truly is, not how it appears from Earth.
What is absolute brightness?
These are sudden, intense bursts of energy on the Sun that release massive amounts of radiation into space.
What are solar flares?
What is the most general level of classification? (Think phylum, kingdom, etc.)
What is domain?
This is the order of the size of objects in the universe from smallest to largest.
What is comet, asteroid, moon, dwarf planet, planet, star, solar system, nebula, and galaxy?
Two stars are the same temperature and color, but one has more absolute brightness. What property must be different between them?
What is size?
These loops of gas that extend out from the Sun’s surface can stretch for thousands of kilometers and are often connected to sunspots.
What are prominences?
What is the order of classification from most general to most specific?
What is Domain, kingdom, phylum, class, order, family, genus, species?
