What else can I help you with?
What are the two important discoveries Hubble made that proved other galaxies exist outside our own?
Hubble discovered that the nebulas were galaxies based on the powerful telescope at Mt Wilson. The second discoveries was the red shift relationship v=HD shows that the galaxies were outside our own galaxies definitely and quantitatively, using light sources in galaxies that were standard sources that could calibrate the distance.
Is the moon giving off light energy?
Yes but not in the way you are thinking. The Moon reflects light but does not produce it's own energy.
Do galaxies emit light?
Yes, galaxies emit light primarily from the stars within them. This light can range from visible light to other forms of electromagnetic radiation such as radio waves, infrared, ultraviolet, and X-rays. The light emitted by galaxies allows astronomers to study their composition, age, and distance from Earth.
Do planets stars and comets shine as a result of reflected light?
Planets and comets shine because of reflected light because they do not produce their own light. Stars are enormous balls of gas that are undergoing fusion which releases a very large amount of energy in the electromagnetic spectrum which includes visible light. So stars shine because they produce their own light and not because they reflect light.
Does light produce heat?
Yes, light does produce heat. When light is absorbed by an object, the energy from the light is converted into heat, which can raise the temperature of the object. This is why objects can feel warm when exposed to sunlight or other sources of light.
What objects can be seen from earth because they produce their own light?
Cities can be seen from space.
What things in space give your their own light?
Stars, galaxies, and quasars are among celestial objects that emit their own light. Stars, such as our Sun, undergo nuclear fusion to produce light and heat. Galaxies contain billions of stars and emit light due to the combined glow of these stars. Quasars are supermassive black holes with surrounding disks of gas that emit powerful radiation.
What objects in space produce light?
Stars, galaxies, nebulae, and other luminous celestial objects emit light in space. These objects emit different wavelengths and intensities of light based on their composition and physical characteristics.
Does the Earth produce its own light?
The earth does not produce its own light but it reflects the light rays from the sun that reaches its surface.
Does an elliptical galaxy make its own light?
a galaxies does not move that is why there are many stars
What objects in space produce their own light?
Objects in space that produce their own light are known as luminous objects. Some examples include stars, such as our Sun, which emit light through the process of nuclear fusion, and hot planets like Jupiter, which reflect and emit light due to their internal heat. Other examples include galaxies, supernovae, and nebulae that emit light due to various astronomical processes.
Why do scientist see the galaxies if they were millions and billions of years ago?
The galaxies beyond our own are millions to billions of light years away, meaning the light takes millions to billions of years to get here.
Do meteoroids produce their own light?
NO
Do lantern fish produce their own light?
they're called "lantern' fish so they pretty much do produce their own light
Does the moon produce any light of its own?
NO it not produce its own light its only like a mirror getting light from the sune a mirror it only get light from the sun
What is an object that does not produce its own light?
A common example of an object that does not produce its own light is the moon. The moon reflects light from the sun, which is why we can see it shining in the night sky.
How do moon produce their own light?
the light from the moon is a reflection of the light from the sun
