Yes, there are some lenticular galaxies that are nearly 13 billion light years from the earth.
Is it the most distant spiral galaxy when it's 13 billion light years from Earth?
Yes, it's the most distant spiral galaxy 13 billion light-years from Earth (i.e. SB-WF 1510-1270 in the Hubble Deep Field South).
Is BX442 the most distant spiral galaxy when it's 10.7 billion light years from Earth?
Yes. BX442 is the most distant spiral galaxy (type Scd) 10.7 billion light-years from Earth. It's located in the Pegasus constellation. It's diameter is ~30,000 ly.
When you observe a distant galaxy whose photons have traveled for 10 billion years before reaching Earth you are seeing that galaxy as it was when the universe was?
Yes. If the photons have travelled 10 billion years, that means you are seeing the galaxy as it was 10 billion years ago.
Is SB-WF 1510-1270 the most distant spiral galaxy when it's 13 billion light years from Earth?
Yes. SB-WF 1510-1270 is the most distant spiral galaxy (type Sbc) 13 billion light-years from Earth. It's located in the Tucana constellation. It's diameter is ~10,000 ly.
How do astronomers observing distant galaxies talk about looking backward in time?
The speed of light is not infinite. Light takes time to travel from distant galaxies to our eyes here on Earth. If a galaxy is 1 billion light years away, it has taken 1 billion years for the light emitted by said galaxy to reach us here, so (obviously) we are seeing the light emitted 1 billion years ago. In a sense, we are seeing 1 billion years into the past at the light emitted by that galaxy.
