That happens when the individual stars are too faint to se seen individually.
It is also because they are so far away from Earth but quite close to each other. It's like seeing two lights which are far away from you. They appear as one big light instead of two separate ones.. It is the same principle with stars.
What else can I help you with?
How many light years are equal to 4.5 billion years?
A light year is a measure of distance, not time. It is the distance light travels in a year.
The longest distance light can travel since the beginning of the universe is known?
Well, it's complicated.The universe is about 13.8 billion years old. In that time, in a vacuum (and while interstellar and even intergalactic space isn't a perfect vacuum, for these purposes it's close enough), light could have travelled 13.8 billion light-years. That's pretty straightforward.Where it becomes non-straightforward is in determining the radius of the observable universe. If there's only been time for light to go 13.8 billion light-years, then the edge of the observable universe should be 13.8 billion light-years away, right?Wrong.Because the universe is expanding, light that started on its way 13.8 billion years ago got a certain percentage of its traveling done when the universe was smaller. It turns out that the earliest thing we can see is the surface of last scattering or the cosmic microwave background radiation (we can't see past that because it's effectively opaque), which is currently about 46 billion light years away. (The theoretically observable universe is actually slightly larger than that, since the decoupling event when the universe became non-opaque happened when the universe was already about 380,000 years old).So, while light can only possibly have gone 13.8 billion light years, light that started on its way to us 13.8 billion light years ago and is reaching us now came from objects that are "now" about 46 billion light years away.
Science says the universe is 12 to 14 billion years old because light from that far away has reached us but couldn't there be objects billions of light years further away?
Yes, current theory and observations suggest that the age of the universe is between 13.6 and 13.8 billion years (earth years).However please note that a light year is the distance a beam of light will travel in one earth year.
Why don't stars appear in photos of astronauts in space?
the light from sun is reflected &it is too bright
How many galaxies are in the Power Rangers Universe?
There are over 100 billion galaxies (with 100 billion+ stars (each containing 9 planets and 170+ moons)) in each one; as well as asteroids and nebulae) in the Power Rangers universe. Their light has taken 13 billion years to reach Earth.
Why do billions of star appear as clouds or patches of light?
Because they are very far away.
Why are the clouds black?
Clouds appear black when they are thick and dense, blocking out sunlight and making them appear dark. This can happen when there is a lot of moisture in the air, causing the clouds to absorb more light and appear black.
What are facts about altocumulus?
Altocumulus clouds are mid-level clouds that form between 6,500 to 20,000 feet above the ground. They appear as white or gray patches or layers in the sky and are often associated with fair weather, although they can sometimes signal changes in the weather. Altocumulus clouds are made up of water droplets and can occasionally produce light precipitation.
Why do billions of stars appear as big patches of light in the night sky?
Billions of stars appear as big patches of light in the night sky due to their distance from Earth. From our perspective, the light from individual stars merges together to create these patches, known as galaxies or star clusters. These collections of stars appear as cohesive shapes due to their sheer number and the vast distances between them and us.
Why do billions of stars appear as clouds or patch of light?
That happens when they are so far away that you can't distinguish the individual stars. Also, to appear as "clouds", there must be a large amount of stars together.
Clouds that form in a blanket like layers are?
stratus clouds. They are low-level clouds that appear in a continuous layer and bring overcast conditions. Stratus clouds can sometimes produce light precipitation.
Which. Planets clouds cover reflects light from the sun making it appear bright in the sky?
Venus
Why do clouds look like cottenballs?
Light reflected back from the water droplets scatters all the colours of the rainbow - making the clouds appear white.
Are clouds dark at night?
No clouds always appear white. It is only night because the Earth is rotating and the Sun is not shining light on that part of the Earth.
What is the color of cumulus clouds?
Clouds are merely water particles suspended in the atmosphere. Their color is heavily dependent on the color of light that enters them. Because the light that comes from the sun is perceived as white, clouds appear white for most of the day. Thunderstorms tend to be fairly large, thus their base appears dark because much of the light from the sun has already been blocked. Becasuse the atmosphere bends the light from the sun in the morning and evening, clouds can appear red or orange during a sunrise or sunset.
What makes clouds turn gray?
Clouds turn gray when they become thick and dense, blocking sunlight from passing through. This reduces the amount of light reflected off the cloud, making it appear gray to our eyes. Gray clouds typically indicate that rain or a storm may be approaching.
What are low sheet-like clouds called?
Low sheet-like clouds are called stratus clouds. They are typically gray or white in color and appear as a uniform layer covering a large portion of the sky. Stratus clouds often bring steady, light precipitation such as drizzle or light rain.
