This is an extremely misleading headline, while it is true. The choice to say "strange modern structures" leads the reader to believe that the structures were previously unknown, and the words modern and structure both relate to building, architecture, and humanity than natural formations. However, this is an article about ice that is refreezing in crater-like formations that scientists have been researching for over a decade. These are natural processes involving ice that scientists are now learning more about, as they have just discovered that the ice is more recently frozen than expected. I don't believe "strange modern structures" to be the most honest way to title an article about this research, as even though the findings are credible and interesting, it invokes thoughts of buildings or structures that are man or otherwise unnaturally made.
