Are some irregular galaxies nearly 13 billion light-years from earth?
Yes, they are usually of a similar size range to other types of galaxies, from a few thousand lightyears across to a million or more. Their formation is often as a result of two or more galaxies colliding, or coming close to each other.
What is the estimated number of irregular galaxies since there are 100 billion galaxies in the universe?
There are at least 5 billion irregular galaxies in the observable universe, at distances up to 13 billion light years.
Does red shift have anything to do with irregular galaxies?
NoRed shift is the Doppler effect as it applies to the light from receding galaxies and stars.As the name suggests, "irregular" galaxies have no specific form, and so the group contains a very diverse selection of objects.
Are some spiral galaxies up to 13 billion light-years from Earth?
Yes. Some spiral galaxies are up to 13 billion light-years from Earth.
Are some lenticular galaxies nearly 13 billion light-years from earth?
Yes, there are some lenticular galaxies that are nearly 13 billion light years from the earth.
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.
Why galaxies look faint from earth?
Because they're hundreds of thousands of light years away from Earth.
Are some spiral galaxies nearly 13 billion light-years from earth?
Yes, there are some spiral galaxies that are nearly 13 billion light years from Earth (I.e. T2003 1529 in the Ursa Major constellation).
Why do galaxies look faint to people on earth?
because they're hundreds of thousands of light years away from earth
How many light years is the earth the the other galaxies?
hi i need help with my homework
Can faint background galaxies be mistaken for stars?
Yes. Far-away galaxies can be mistaken for stars and occasionally are. This is due to the galaxies being millions upon millions of light years (the distance light can travel in a year) away from earth.
When viewed from earth the light from very distant galaxies shows a red shift evidence that these distant galaxies moving towards or away from earth?
The "redshift" refers to the fact that the light is less energetic than when it was emitted; it shows that the galaxies move away from us. Should a galaxy move towards us - which is possible only for galaxies that are relatively close to us - then there would be a blueshift.
