Can we draw the following hypothesis from the context?

Context:

The Multiwavelength Atlas of Galaxies is a textbook and atlas of 35 well studied galaxies (including our Galaxy) authored by Glen Mackie of the Centre for Astrophysics & Supercomputing, Swinburne University of Technology. It was originally published in 2011 by Cambridge University Press.

Hypothesis: The Multiwavelength Atlas of Galaxies is the only atlas on galaxies.
It's impossible to say
