Hovering 250 miles (400 kilometers) over Earth, astronauts aboard the Worldwide Area Station (ISS) regarded down on our planet final Could and noticed a heart-shaped oasis blooming within the Egyptian desert. Immediately (Feb. 14), our buddies in house are sharing the hanging picture as a particular Valentine for the entire planet, courtesy of NASA’s Earth Observatory web site.
Generally known as the Faiyum Oasis, this lush coronary heart within the desert is definitely a broad wetland basin that extends over 450 sq. miles (1,200 sq. km) – about one and a half instances the world of the 5 boroughs of New York Metropolis. Whereas it might be nowhere close to as populous because the Large Apple at present, the oasis has sustained human life for roughly 8,000 years, in response to NASA, and was the staging floor for a number of the most bold feats of engineering in historic historical past.

Fed by a pure channel of the close by Nile River often known as the Bahr Yussef, the oasis was as soon as a shimmering lake known as Lake Moeris. The lake’s existence trusted seasonal floods from the Nile, in response to the College Faculty London (UCL) geography division. When the Nile floodwaters have been too low, the rulers of historic Egypt typically took daring measures. There may be proof {that a} succession of pharaohs dwelling some 4,000 years in the past addressed one notably extreme water scarcity head-on by enlarging the Bahr Yussef to manually return water to the area.
“This was one of many earliest huge nationwide hydrological initiatives on the earth,” in response to the UCL web site. “The twelfth Dynasty kings accountable have been Amenemhat I-III they usually acquired the title of ‘engineering kings’.”
Immediately, the traditional lake lives on because the a lot smaller Qarun Lake (seen under the center in NASA’s picture). Due to these engineering works of antiquity, the remainder of previous Moeris’ sprawling lakebed stays a fertile oasis that helps many villages, cities, farms and orchards – which you (and the astronauts) can see within the grey patchy areas that make up the oasis’s coronary heart within the picture above.
And so, we thank the traditional pharaohs for this geographical valentine. Let’s hope their hearts are nonetheless the place they need to be.
