How Do Electrons Affect The Color Of The Stars?

580 Words3 Pages

The Color of the Stars Madilyn Moore Seward High School Human beings have been looking up at the stars for thousands of years, many of them wondering what they are. Once astronomers determined that the stars were flaming balls in outer space, it seemed that not all stars burned the same; that different elements and chemicals constructed the stars. One of the ways that astronomers group stars is by using color (“Color of the Stars”, n.d.). This gives them the ability to determine important information about what they are made of and how hot they are. When certain chemicals are heated up the electrons move. Electrons that move more have a smaller wavelength. Electrons that do not movre as much have a larger wavelength. The temperature of a star can have a large effect on what color people see. When an element is heated up, it excites the electrons and causes them to jump up and then go back down the electron …show more content…

It’s color is never the same because the surface temperature changes “depending on the type of fusion reaction fuelling the star at the time”(“Stars Great and Small”, n.d.). As a star nears the end of its life, it will get more and more red or orange because its temperature is decreasing. Not only do stars change color because they are dying, but also because of absorption lines. These “lines are created when light from something hot like a star passes through a cooler gas, cancelling out the emission lines the chemicals in the gas would normally create”(Gary, S, 2010). Absorptions lines are what make stars have dark streaks in them and causes them to look uneven. It is incredible how electrons, some of the most miniscule things existing, have such a large impact on everything that humans know. The smallest amount of movement from them can change the color of stars. Human beings now longer have to look at stars and wonder what they

Hero Syndrome: Volunteer Firefighters

1828 Words | 8 Pages

While watching the fire, the colors of the flames are indicative of the intensity of the fire. Sometimes they can also reveal whether or not substances are present. The colors range from yellow, to red, and blinding white. It is important to note the size of the fire. The first person on the scene should note the size of the fire when they arrive and document in intervals thereafter.

Anne Rooney The History Of Astronomy Summary

1350 Words | 6 Pages

New stars that were discovered would be classified by position, color, brightness, and later size and composition. Galileo discovered a bank of thousands of stars, originally thought to be a cloud. The universe has mysteriously expanded, “Suddenly stars which no being on earth had ever seen before came into view” (Rooney 157). Due to this expansion, the number of discovered stars rapidly increased. Hipparchus created a star catalog that logged stars' positions.

Hertzsprung-Russell Lab Report

521 Words | 3 Pages

A Hertzsprung-Russell (H-R) Diagram is an important tool in astronomy. This diagram helps astronomers learn the age and distances of stars and star clusters, (pg 171, Lab Manual). Typically, an H-R Diagram plots Luminosity (y-axis) against Temperature and Spectral Type (x-axis) (this axis is also “backwards” meaning that temperature is higher on the left and lower on the right). In the upper left corner of the diagram, you would see hot luminous stars plotted there, and in the bottom right there would be cool, faint stars.

A little awhile in astronomical terms later, (hundreds of millions of years or billions of years) after it has run out of helium in the core, it will shrink, then explode outwards as a new “shell” of helium sinks down to the core. When that helium core ignites, it sheds the outer material off the star, and that material is the material that forms a planetary nebulae, leaving it’s atomic material (such as hydrogen and helium) to restart the cycle when the time comes. All stars die, it may not be immediately in a human lifetime, it might take hundreds of thousands of generations of humans, however, all stars die, and ours is no different from any other. Our sun will turn into a red giant, it’s diameter by a factor of

Blue And Nebula Compare And Contrast

437 Words | 2 Pages

Stars are hot bodies of glowing gas that start their life in Nebulae. They vary in size, mass and temperature, ranging from 450x smaller to over 1000x larger than that of the Sun. Now, the color of a star is determined by its temperature, the hottest stars are blue and the coolest stars are red. The energy produced by the star is by nuclear fusion in the star’s core. The brightness is measured in magnitude, the brighter the star the lower the magnitude goes down.

Interstellar Star

1544 Words | 7 Pages

High-mass stars have a few similarities to low-mass stars, as they are both created from an interstellar cloud collapsing, and they go through similar phases, but high mass stars are different from low-mass stars because they are born from larger clumps than ones that create stars similar to the sun. Because the clump is greater and its mass is greater too, which causes it to squeeze more and in doing so heats up the star more than the sun. Therefore, when the star reaches the main sequence stage of its life it is way hotter, more luminous and blue. When a star has such a high luminosity it means that it will burn through it’s fuel, hydrogen, faster so instead of it taking 10 billion years to use all its hydrogen, it actually uses up the fuel in 100 million years or less depending on the star. This causes the star to age significantly faster and once it runs out of hydrogen it begins to grow bigger in size and cool down like a low-mass star, although the massive star goes through the pulsating yellow giant phase before it can reach the red giant stage.

The electrons pattern changed simply by being observed. Such a strange finding had to be replicated, so in 2002 another team of researchers attempted to do the same thing faster at a smaller scale.
