What's the most distant observed star which is not a supernova or quasar?

In summary, the most distant observed star is Icarus, estimated to be 9 billion light years away from Earth. However, there have been other stars observed at even greater distances, such as MACS J1149 Lensed Star 1, estimated to be 13.28 billion light years away. Scientists determine the distance of these stars by measuring redshift and using other methods. It's possible that there are even more distant stars yet to be discovered. These distant stars can only be seen with powerful telescopes and specialized equipment, not with the naked eye.

I hear that large telescopes can resolve the Andromeda galaxy into individual stars. Is it possible to do the same for galaxies outside our local group? Also, have we observed any stars which sit in deep inter-galactic space, far from any galaxies?

I would guess a cepheid, you can certainly see them out to the local group (that's pretty much how you determine a galaxy is in the group) I don't knwo what the record is.
 

1. What is the most distant observed star?

The most distant observed star is currently Icarus, which is estimated to be roughly 9 billion light years away from Earth.

2. Is Icarus the only star that has been observed at such a great distance?

No, there have been other stars observed at great distances as well, such as MACS J1149 Lensed Star 1 which is estimated to be 13.28 billion light years away.

3. How do scientists determine the distance of these stars?

Scientists use various methods, including measuring the redshift of the star's light, to calculate the distance of these distant stars.

4. Are there any other stars that could potentially be observed at an even greater distance?

It is possible that there are other stars that are even further away, as the observable universe is constantly expanding and new discoveries are being made.

5. Can we see these distant stars with the naked eye?

No, these distant stars are only visible with powerful telescopes and specialized equipment.
