Scientists compared nighttime lights seen by NASA satellites and @cdc health data.
They found that poorer, non-white neighborhoods experience more artificial light at night, which can disrupt circadian rhythms and cause sleep deficiency. #DarkSkyWeek

Warming Makes Droughts, Wet Events More Frequent, Intense
Scientists have predicted that droughts, floods will become more frequent and severe as our planet warms and climate changes, but measuring this on regional scales has proven difficult.Jennifer Fadoul (NASA)
The scientists analyzed 20 years of GRACE and GRACE-FO data in the study.
These satellites use Earth’s gravity to measure changes in water stored in soils, lakes, aquifers, snow and more.
