What type of spectrum do most stars have?
The spectrum is a kind of analysis of the light emitted by a star.
What type of energy is received on earth from the sun and other stars?
Heat, visible light, and infrared light (UV Rays) are the three main types of energy emitted from the sun and stars. Although, around 30% of it does get forced back into space.
Which types of stars are invisible?
If a star is younger in years than it is distant in light years we will not see it. It is there but because of its age and distance the star will be unseen as the light emitted from it has not reached us. Also black holes which use to be stars are 'invisible' as they do not emitt or reflect light.
Do the Stars reflect the Suns light?
No, they also produce their own light through nuclear fusion. Only planets and moons reflect sunlight.No, Stars do not reflect the Sun's light. Every star in the universe creates and distributes it's own light through nuclear fusion, and does not reflect light. The stars you see in the sky at night are a result of light traveling millions of miles towards earth by their own light that they emitted, not the light that the sun produced and then reflected back towards us.
What happens to cause stars to start emitting light?
Just like in the sun, the cores of stars fuse hydrogen into helium, emitting enormous amounts of energy in the process. A fair portion of that is emitted as visible light.
What makes some stars look brighter then others?
How big, how hot (color/amount of energy emitted), how far, light pollution at viewing site
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red of the electromagnetic spectrum?
He noted that light emitted from stars is shifted further toward the red of the electromagnetic spectrum . From this he concluded that the universe was expanding.
What is the nature of the energy emitted by stars?
The energy is called electromagnetic radiation (light energy).
What are 3 things that visible light can be emitted by?
stars, flashlights, toasters, CFLs, LEDs, fireflies
What type of spectrum do most stars have?
The spectrum is a kind of analysis of the light emitted by a star.
What did hubble conclude when he noted that light emitted from stars is shifting towards the red end of the electromagnetic spectrum?
Whatdid hubble conclude when he noted that light emitted from stars is shifting towards the red end of the electromagnetic spectrumA. The universe is expanding
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red end of the spectrum?
That they were receeding
Are all nebulae luminous?
Technically, no nebulae are luminous. The ones that appear as such have stars either within or near them, and the nebulae merely reflect the light emitted by these stars.
What color are the cooler stars?
Colder stars emit red light. Hot stars emit large amounts of green light with small amount of red and blue light, which balances out to a white color in human eyes.
What produces heat and light in stars?
The heat and light emitted from stars is due to the nuclear fusion within their cores. Stars are so massive that their gravity crushes atoms so close together that their nuclei begin to snap together, releasing loads of energy in the form of light.
What did hubble conclude when he noted that light emitted from stars is shifting toward the red end of that electromagnetic spectrum?
(A) The universe is expanding.
What did Hubble conclude when he noted that light emitted from stars is shutting toward the red end of the electromagnetic spectrum?
The universe is expanding.
