What are the ways in which stars are differ in one another?
Principally by size. Larger stars are hotter and brighter. Next by age. As stars get older, they begin to run out of hydrogen fuel, start using helium and swell to red giants. Lastly by composition. Stars that formed earlier tend to have less carbon, oxgyen and "metals" in them.
Light and other forms of electromagnetic radiation are given off by stars using energy released during?
Light and other forms of electromagnetic radiation are given off by stars using energy released during nuclear fusion processes occurring in their cores. As a star converts hydrogen into helium through nuclear fusion, tremendous amounts of energy in the form of light and heat are produced and emitted into space. This is what provides the light and warmth we receive from stars such as our Sun.
Are stars radioactive?
Yes. Stars prouduce light as a product of nuclear fusion.
What is a star that has collapsed after using its fuel?
A collapsed star after using up its fuel is called a white dwarf, neutron star, or black hole, depending on its mass. White dwarfs are remnants of low to medium mass stars, neutron stars are remnants of massive stars, and black holes are formed when very massive stars collapse.
What fuel is the sun using to release energy?
Our sun, Sol, uses hydrogen for fuel.
What is the name for the portion of a stars life cycle when it is using hydrogen for fuel?
white dwarf
What is the name for the portion of a star life cycle when it is using hydrogen for fuel?
The phase of a star's life cycle where it is using hydrogen as fuel is called the main sequence phase. During this phase, a star converts hydrogen into helium through nuclear fusion in its core to produce energy and maintain its stability.
What is a fuel for a star?
Most stars process Hydrogen using nuclear fusion and turn it into Helium.
How did gold get made?
All elements, including gold, excepting hydrogen, helium, and lithium, were made inside stars using nuclear reactions.
How scientist discovered that start were made up of hydrogen?
Probably by using a spectrometer, analyzing the light for the colour makeups that identify the different elements uniquely. Stars are made of both Helium and Hydrogen, they are in constant fusion which gives light and heat to our planet, the light can be broken down into different "Wavelengths" which are identified by colour, ranging from IR(Infrared) to UV(UltraViolet) and the rainbow of colours that are visible to the naked eye are between those, hydrogen particles release their own unique combination of these colours in the light they produce.
What information is needed about the star in order to estimate its age using the star life cycle?
You need to know the mass, and the percentage of hydrogen and helium in the star.
Why do starts need helium?
stars* and they don't need helium they make helium from hydrogen using nuclear fusion omg im 13 and i know this
What other information is needed about the star in order to estimate its age using the star life cycle?
You need to know the mass, and the percentage of hydrogen and helium in the star.
Why do stars evolve off of the main sequence?
Because they have exhausted their supply of hydrogen in the core. They might reenter the main sequence later, but that will be using hydrogen in the shell (the branch phase) rather than the core.
Who first thought of using a telescope for looking at the stars?
Galileo is the first thought of using a telescope for looking at the stars.
Who was using the hydrogen bomb?
the hydrogen bomb has never been used in war
