Dar de fapt este o imagine satelitară cu false culori a Rub ‘al Khali, care este cel mai mare deşert continuu de nisip din lume. Rub ‘al Khali are nişte condiţii ostile incredibile.
Situat în sudul Peninsulei Arabice, deşertul Rub ‘al Khali este un mediu dur. De obicei, precipitaţii cad mai puţin de 3,55 de cm pe an, temperaturile adesea depăşesc 49 de grade Celsius, iar vânturile puternice formează dune de nisip care pot ajunge la înălţimi de 250 de metri.

Pe imaginile făcute de Agenţia Spaţială Europeană a Sentinel-2, aceste dune apar ca linii galbene strălucitoare. Între timp, culorile de maro şi violet indică prezenţa mineralelor, inclusiv sarea sau gipsul.
