All of 'em more than 6014 light-years distant.

It looks much, much nicer in larger size.

This is true. For perspective, when you look up towards the sun, you’re seeing what it looked like (and where it was) eight minutes prior.

Is a most fascinating place which is called the present when in the present one can view only the past.

eXtreme Deep Field 13 billion years ago, when the universe was only a few percent of its present age. Ah, I remember the good old days!
We didnt have easy like you kids do.
We had to walk through knee deep quasars up hill to school; both ways!

Thank You, Civ, for today’s present.

Light time between the earth and moon.
The New Horizons spacecraft is currently about 3 hours and 25 light minutes from earth.

Makes me wonder what they look like in the present. Also keep in mind that light from some of these galaxies and photo-galaxies have been red-shifted to significantly longer wavelengths than they started out due to the universe's expansion. What we are seeing now in the 'visible' range may have started out in the UV or even shorter. Galaxies can emit very different images in visible vs UV and other ranges.

From NASA.gov:
“An astronomical object can look very different depending on what wavelength is used in its detection. The object’s appearance often changes across the electromagnetic spectrum because various physical processes result in emission in different wavelength regions. Images of emission can be made by mapping brightness to colors (see “Making an Image”). For example, the optical image of the Andromeda galaxy (below left) shows glowing stars. And dark dust lanes trace out a spiral arm structure. An infrared image of the galaxy (below right) shows several concentric rings of dust rather than spiral arms. The dust is too cold (-260 degree C) to be detected in optical light.
Below are five images of the galaxy M 33. [see link]
Each image is taken in a different wavelength region.
In the X-ray image, we see very hot, diffuse interstellar gas, and bright point-like X-ray sources, such as X-ray binaries.
The brightness in the ultraviolet image indicates star formation activity. Stars are visible in the optical image.
Red supergiant stars and dust heated by massive star formation are highlighted in the near-infrared image, which looks similar to the optical image.
The radio image maps out hydrogen gas in the galaxy. The red coloring is indicative of gas moving away from our line of sight. The blue colors gas moving toward us (a phenomena described by Doppler shift).”

Light time between the earth and moon.Is about 1-1/4 seconds.

The New Horizons spacecraft is currently about 3 hours and 25 light minutes from earth. For those who aren't aware, one light-second is about 186,000 miles.
So that's 186,000 x 60secs x 60mins x ~3.5 (miles). = 2,343,600,000 miles (~2.3 billion miles)

Yes, and it was really exciting getting past those black holes. Seeing them was the first challenge.
