The Sun
The Sun produces energy in its core through this process involving hydrogen and helium
What is nuclear fusion?
These are dark areas of plasma that are cooler than the surrounding surface.
What are sunspots?
This large cloud of gas and dust contains an immense volume of material and is the birthplace of stars.
What is a nebula?
According to the "Roy" rule, a star with this color has a temperature of less than 3,500K.
What is red?
This is the study of how light interacts with matter to identify what objects are made of.
What is spectroscopy?
The Sun is classified as this specific, "ordinary" size of star.
What is a mid sized star?
These are huge loops of plasma that occur in pairs and follow magnetic forces.
What are prominences?
This is the first stage of a star's formation, where nuclear fusion begins.
What is a protostar?
These are the largest of all stars, created when gas starts to run out.
What is a super giant star?
We live in this specific spiral galaxy.
What is the Milky Way?
Energy leaves the core in the form of these high-energy rays.
What are gamma rays?
These erupt into space when loops in sunspot regions suddenly connect.
What are solar flares?
This blue-white core is what remains after a star runs out of fuel.
What is a white dwarf?
A star with a temperature of 30,000 to 60,000K is this color.
What is blue?
These young galaxies have black holes at their centers and are the farthest known objects.
What are quasars?
This outermost layer of the Sun's interior features rising and sinking loops of plasma.
What is the convection zone?
The Sun is made of hydrogen and helium in this state of matter (a hot fluid-like gas).
What is plasma?
This violent explosion occurs when a high-mass supergiant runs out of fuel.
What is super nova?
This type of star is smaller than the sun and does not shine as brightly.
What is a red dwarf?
This is the distance light travels in one year; it is a unit of distance, not time
What is a light year?
Scientists believe the entire solar system formed from a cloud of these two things.
What are gas and other materials?
: This middle layer of the sun's interior is where energy moves outward as radiation.
What is the radiative zone?
A star's lifespan depends on this specific physical property
What is mass?
These are the two elements that make up about 75% and 25% of stars, respectively
What are hydrogen and helium?
This term describes how bright a star actually is, rather than how it looks to your eyes.
What is luminosity?
