Images sent back to earth from the hubble telescope were the first to show the

"the galaxies one after another scattered in the universe to their ends"

At the beginning of 1994, the new images that NASA showed were absolutely spectacular. The telescope could now see with the precision with which it had been designed initially.

Since then, 4 additional interventions have been made in the telescope. The original detectors have been replaced by others increasingly sensitive and higher performance and had their own compensation systems for the wrong optics of the main mirror. During the last campaign, which took place in May 2009, the COSTAR corrector was removed and replaced by a new spectrograph.

The observations made by Hubble have covered objects from the solar system to far distant galaxies, leaving a legacy absolutely outstanding to astronomy. Among its results we must highlight the images known as the Deep Field and the Ultra Deep Field. These are the most sensitive images obtained in the history of optical astronomy, small regions of the sky that reveal innumerable galaxies to the ends of the universe.

they were unable to pay their debts

the east coast has nothing to do with the dust bowl, the dust bowl killed a full year's worth of crops in seconds, and with the dust on the land, the land would be worthless.   furthermore the farmers couldn't  get  out of their houses due to the dust so when the bank came to collect money, farmers couldn't  pay it
