Analyzing Starlight
The name we give large celestial bodies that are composed of gas and that emit light.
What are stars?
Astronomers refer to this term to describe the location on the H-R diagram where most stars lie; it has a diagonal pattern from the lower right to the upper left.
What is main sequence?
Clouds of gas and dust rotate, and much of the gas and dust is pulled to the center of the cloud. At this point, this star begins to form. Though it gives off lots of heat, it does not glow with visible light.
What is a protostar?
The metric system uses powers of this number to make conversions.
What is powers of 10?
Anything that takes up space and has mass is considered this.
What is matter?
The color of the hottest stars which average surface temperatures of 35,000*C.
What is blue?
On the H-R diagram, giants and supergiants can be found in this location of the graph. Provide both a vertical and horizontal direction.
What is the upper right?
These stars have lower mass and live longer than higher mass stars. Our Sun is one of these.
What is a Sun-like Star?
The branch of science that is the scientific study of the universe.
What is astronomy?
The name of the solar system's largest volcano, located on the planet Mars.
What is Olympus Mons?
The name given to stars in the Northern Hemisphere that appear to circle the North Star and never dip below the horizon due to apparent motion.
What are circumpolar stars?
The cause of a supergiant star exploding as a supernova comes from this.
What is pressure from gravity?
Towards the end of their life cycles, higher mass stars expand into these enormous stars. The biggest are 1,000 times wider than our Sun!
The piece of lab equipment in a science lab that should be used to determine a liquid's volume.
What is a graduated cylinder?
An occurrence when a substance reacts and forms one or more new substances.
What is a chemical change?
The shift a star undergoes as it moves away from our solar system according to the Doppler Effect.
What is red shift?
A star that has collapsed under gravity to the point that the electrons and protons have smashed together to form neutrons.
What is a neutron star?
Lower mass stars eventually release their outer layers as this huge cloud of gas. The core shrinks down to a tiny white-hot object about the size of the Earth.
What are a White Dwarf & Planetary Nebula?
What is blob tectonics?
Saturn is most known for these features, which are visible from Earth even through a small telescope.
What are its rings?
Astronomers refer to the measurement of the brightness that a star would have at a distance of 32.6 light-years from Earth as this.
What is absolute magnitude?
A rapidly spinning neutron star that emits pulses of radio and optical energy.
What is a pulsar?
This is the final stage in the life-cycle of the most massive stars. The gravity around these is so strong that light cannot escape.
What is a black hole?
The Italian mathematician, astronomer, and physicist who made so many contributions to science that he is often called the father of modern science.
Who is Galileo Galilei?
Once considered the ninth planet of our solar system, Pluto was found to fill so few planet characteristics it became reclassified as this.
What is a dwarf planet?
