What is the source of all light in outer space?
The source of light in outer space varies. Light can be reflected off from the stars, moons, comets, asteroids and planets.
A telescope collects electromagnetic radiation from outer space and does what to it?
Yes a telescope collects electromagnetic radiation (light) an then brings this light to a focus so that the source of the light is magnified. The larger the diameter of the telescope, the more light it collects making the image at the focus brighter so as well as magnifying the image a telescope also allows one to see fainter objects.
Why does shiny and light coloured objects reflect more light than rough and dark objects?
Shiny and light-colored objects reflect more light because they have a smooth surface that allows light to bounce off more directly. In contrast, rough and dark objects have uneven surfaces that scatter light in different directions, leading to less reflection and absorption of light.
What is the light outer part of the shadow?
The light outer part of a shadow is called the "penumbra." It is the region where some light is obstructed, but not completely blocked, resulting in a gradient of light and shadow. This area surrounds the darker central part of the shadow, known as the "umbra," where the light source is entirely blocked. The penumbra creates a transitional zone between light and shadow.
What is the lighter outer part of the shadow during an eclipse?
The lighter outer part of a shadow during an eclipse is called the penumbra. In this region, only a portion of the light source is obscured, allowing some light to reach the area, resulting in a partial shadow. This contrasts with the darker central area known as the umbra, where the light source is completely blocked. As a result, observers in the penumbra experience a partial eclipse.
What is the best aerodynamic shape for objects that move less than the speed of light?
To move near the speed of light, you would be moving in outer space. In this case, an "aerodynamic shape" is not relevant, since there is no atmosphere.
How far does the suns light shine?
The sunlight travels through the vacuum of space until it reaches an object to be reflected or absorbed. This can include objects like planets, moons, asteroids, and spacecraft. The light from the sun can reach objects as far as the outer reaches of our solar system.
What is the outer portion of the shadow cast on Earth by the Moon called?
The outer portion of the shadow is called the "penumbra".
How do you know light can travel through outer space?
Light can travel through outer space because it propagates as electromagnetic waves, which do not require a medium to travel through. This means that light can move through the vacuum of space without any obstacles. This property of light allows it to travel vast distances from its source, such as from stars to telescopes on Earth.
The bright hazy light around the moon in a total solar eclipse is the sun's?
The bright hazy light around the moon during a total solar eclipse is the sun's corona, which is the outer atmosphere of the sun. This corona is usually hidden from view by the sun's bright light, but during a total eclipse, when the moon completely covers the sun, the corona becomes visible. It appears as a glowing halo, often with a wispy or feathered appearance, and provides a stunning contrast to the darkened sky.
Can you see color in outer space?
There is no atmosphere in outer space to scatter light, so colors as we see them on Earth would not appear the same. However, objects in space still have intrinsic colors based on their composition and the way they reflect or emit light. Astronauts in space can still see these colors to some extent.
Why is only 50 percent of the solar energy that reaches the outer atmosphere absorbed by Earths surface?
The Earth looks bright - thus much of the light reaching Earth is reflected back into space.
