Explanation: In the distant universe, time appears to run slowly. Since time-dilated light appears shifted toward the red end of the spectrum (redshifted), astronomers are able to use cosmological time-slowing to help measure vast distances in the universe. Featured, the light from distant galaxies has been broken up into its constituent colors (spectra), allowing astronomers to measure the cosmological redshift of known spectral lines. The novelty of the featured image is that the distance to hundreds of galaxies can be measured from a single frame, in this case one taken by the Visible MultiObject Spectrograph (VIMOS) operating at the Very Large Telescope (VLT) array in Chile. Analyzing the space distribution of distant objects will allow insight into when and how stars and galaxies formed, clustered, and evolved in the early universe.

I marvel at the vastness—billions of suns and planets—unimaginable distances! What worlds must be there! At each moment, the entire cosmos is destroyed and recreated. And all of this in the Mind of God.

Does it show up correctly on a phone?

Don’t have a phone I can check on, but I don’t see why not.

Today I changed the HTML for photo sizing. Previously it was a fixed size.
