Why do stars light up the sky?
Stars generate light by nuclear fusion. That happens in their cores, but the outer layers glow with it.
What does a star become when it casts off hydrogen and helium gases in its outer layers?
When a star exhausts its hydrogen and helium in the outer layers, it can become a red giant and eventually shed those outer layers, leading to the formation of a planetary nebula. The core that remains can become a white dwarf, which is a dense, hot remnant that will gradually cool over time. This process marks the later stages of stellar evolution for medium-sized stars.
Which type of spectrum do most stars have?
Most stars have absorption spectra. In other words, stars possess thin outer layers that allow light to pass through. These layers produce what are called absorption lines. This means the light from the sun and stars are absorption spectra.
What are the layers of earth composed of?
there are 4 layers crust- dirt, mantel- hot rock, outer core- liquid metal, inner core- solid metal.
What are the 3 layers of the interior?
There are 4 layers in the earth these are crust, mantle, inner core and outer core. The crust is made of the ocean crust and the continents. The mantle is made of plastic it is very hot liquid. The outer core is very hot liquid. And the inner core is hot solid made mainly of iron. :) :P <3 .....
How does stars like the sun become a red giant?
Stars like the sun become red giants as they exhaust their core hydrogen fuel, causing the core to contract and the outer layers to expand. This expansion results in the outer layers cooling and emitting more red light, hence the term "red giant." The star's outer envelope eventually expands to a point where it engulfs the inner planets in the solar system.
What causes the star to eject its outer layer?
Stars eject their outer layers during the final stages of their lives due to the depletion of nuclear fuel in their core. The core contracts, while the outer layers expand and may eventually be expelled in events like supernovae or planetary nebulae formation.
What are 3 layers of the interior of the earth?

What is the very small faint hot star?
A very small, faint hot star is typically referred to as a "white dwarf." These stars are the remnants of medium-sized stars that have exhausted their nuclear fuel and shed their outer layers, leaving behind a dense core. White dwarfs are extremely hot initially but have low luminosity due to their small size, making them faint compared to other stars. Over time, they cool and fade further, eventually becoming undetectable.
What do the pattern of lines in a stars absorption spectrum represent?
read the Earth science book you will find the answer
What stars exhausted of helium its outer layers escape into space leaving only the core the core contracts or gets smaller?
white dawrf
What kind of stars form red giants?
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
