What else can I help you with?
How can you see stars if they are millions of light years away?
Because 1) they are very bright, most of them are bigger than our sun 2) light travels very quicky when you look at them, you are looking at the star about hundreds of millions of years ago, as that is how long it takes for the light to get to here.
What do stars look like in real life?
The stars in the sky are very much like our Sun.
What causes stars to look smaller than they really are?
Stars appear smaller than they really are due to their immense distance from Earth. The light from stars gets spread out over a large area as it travels through space, making them appear as tiny points of light in the night sky. This phenomenon is known as angular size reduction.
Why don't we get heat and light from the other stars than the sun?
We do get light from the other stars; that is why we can see them. We do not feel their heat or see very much light from them because they are millions of times farther away from us than the sun is.
How can stars that are invisible to the naked eye appear on photographs?
There are two ways that this is possible. First, many photographs of space use telescopes, which magnify the stars, allowing us to see stars that we could not otherwise see. Additionally, many pictures taken at night use very light-sensitive methods of photography, methods more sensitive than the human eye.
Why are some of the stars very faint?
Some stars appear faint because they are located far away from Earth, making them difficult to see with the naked eye. Others may be faint due to their size and temperature, emitting less light compared to brighter stars. Dust and gas clouds in space can also block or dim the light from stars, making them appear fainter.
Very faint very dense Earth-size stars are?
Red and White dwarf stars.
How can you see stars if they are millions of light years away?

Why do we need very dark nights to be able to observe the star?
The faint light from many stars will only really show on a very dark, cloudless night. Light pollution from nearby cities also affect whether you can see the stars clearly. If you are in an area where there are no lights (out at sea, in the countryside, etc) the stars will often appear very bright and their numbers impressive.
Do stars also reflect the sun?
No, stars do not reflect the sun like the moon does. Stars are very similar to the sun and give off their own light. (They look small because they are far away, but they are actually very big).
How cats and mice can see in very faint light?
because they have sharp eyes .
How does light pollution in cities affect astronomical observations?
The additional lights from street lamps and buildings gets sent into the sky which in turn gets scattered by our atmosphere, and this hinders very faint galaxies, nebula, planets and stars to be seen.
Why do stars take so long to change?
The stars are light years away which is the distance light travels in a year. A light year is about 3x108km. The farther something is from you the slower they seem to travel so the stars don't look like the are moving. In reality, they are moving very fast.
What is the very small faint hot star?
A very small, faint hot star is typically referred to as a "white dwarf." These stars are the remnants of medium-sized stars that have exhausted their nuclear fuel and shed their outer layers, leaving behind a dense core. White dwarfs are extremely hot initially but have low luminosity due to their small size, making them faint compared to other stars. Over time, they cool and fade further, eventually becoming undetectable.
Why does the milky way look like a hazy band of stars in the sky?
The Milky Way appears as a hazy band of stars in the sky because we are viewing it edge-on from within the galaxy. The combined light of billions of distant stars, interstellar gas, and dust within the plane of the galaxy creates this band of light across the night sky.
Why are dwarf stars hard to find?
Dwarf stars are hard to find because they are small and faint compared to other types of stars, making them more challenging to detect with telescopes. Additionally, dwarf stars are abundant in the universe, but they are typically located far away from Earth, making them difficult to observe in detail.
What do a blown hid bulb look like?
In the part where the electrodes arc will be a little bit black. It may be very faint but if held up to light you should see a little black smudge.
