how do constellations represent historical and cultural views of star groups
Groupings of stars that people across different cultures throughout history have interpreted as recognizable patterns in the night sky, often forming shapes that represent animals, mythological figures, or objects, and serving as a way to understand the seasons, navigate, and tell stories based on their cultural beliefs
Explain conditions that produce a supernova.
It is a massive star that reaches the end of its life, runs out of fuel and its center collapses under its gravity. This causes a huge explosion, which is one of the most energetic events in the universe.
black hole
A region of space has a gravitational field so intense that no matter or radiation can escape.
Giant stars
Any star having a larger radius and brightness than a main-sequence star of the same surface temperature.
Neutron star
Their cores have such powerful gravity that most positively charged protons and negatively charged electrons in the interior of these stars combine into uncharged neutrons
What is a light-year
a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 10^12 km (nearly 6 trillion miles).
Explain the current thinking about black holes.
It is a current scientific understanding that views black holes as extremely dense objects with such intense gravity that nothing, not even light, can escape from within their event horizon, essentially a point of no return. They are crucial for understanding basic physics and the evolution of galaxies.
Black hole singularity
A place where matter is compressed to an infinitely tiny point and all conceptions of time and space completely break down.
H-R diagram
Hertzsprung-Russell diagram, in astronomy, graph in which the absolute magnitudes (intrinsic brightness) of stars are plotted against their spectral types (of star)
nova
What Relate the color of a star to its temperature
The Hotter Stars appearing blue or white, while cooler stars appear red or orange
Celestial sphere
An imaginary sphere where all the objects in the heavens are projected
Planetary nebula
a region of cosmic gas and dust formed from the cast-off outer layers of a dying star
How are stars categorized in the H-R diagram
based on their surface temperature (plotted on the horizontal axis) and luminosity (plotted on the vertical axis)
Constellation
A group of stars forming a recognizable pattern that is traditionally named after its apparent form or identified with a mythological figure. Modern astronomers divide the sky into eighty-eight constellations with set boundaries.
Luminosity
the natural brightness of a celestial object (as distinct from its apparent brightness diminished by distance).
Describe how stars are born, evolve, and die.
Stars are born within large clouds of gas and dust called nebulae, where gravity causes the material to clump together, forming denser regions that eventually heat up enough to start nuclear fusion, marking the birth of a star. Stars die when they run out of nuclear fuel
Event horizon
A theoretical boundary around a black hole beyond which no light or other radiation can escape.
Main sequence
White dwarf
the dense, hot remains of a star like our sun after it has used all of its nuclear fuel and removed its outer layers, forming a planetary nebula, leaving behind an earth-sized extremely dense core.
