It's #WhereInTheWorld Wednesday! This peninsula in Wisconsin, seen by #NOAA21 on April 22, 2026, separates the southern part of the Green Bay from Lake Michigan. It is named after a treacherous water passage called "Porte Des Morts" that lies off the tip, where currents from the bay and lake converge.

Time for another #WhereInTheWorld Wednesday! On April 21, 2026, the #NOAA21 🛰️ captured an image of this lake. It has been dry for most of recorded history, and was once connected to two other lakes during the Late Pleistocene. Though no one has seen that ancient body of water in modern times, geologists call it Lake Bonneville.

Happy #EarthDay from @NOAA Satellites! 🌎 Since 1970, our satellites have watched over our planet, capturing its beauty and power from above. 🛰️ For #EarthDay2026, we celebrate our stunning, dynamic home—and the science that helps us better understand and protect it.

Get ready for another #WhereInTheWorld Wednesday! Sometimes, when we look down at Earth with our satellites, it looks back! On April 18, 2026, the #NOAA20🛰️engaged in a staring contest with this eye-shaped lake. It also happens to be the deepest lake in the United States, with a depth of nearly 2,000 feet. To add to all the whimsy, the “pupil” is known as Wizard Island!

Earth isn’t just getting brighter—some areas are brightening and others are dimming because of changes in nighttime lights. The finding comes from analyzing 1.16 million NASA satellite images taken every night for nine years.
Map showing how nighttime light on Earth changed from 2014 to 2022. Gold areas indicate brighter nighttime lights. Purple areas indicate dimmer nighttime lights. White areas indicate a mix of brightening and dimming. The United States has gold areas on the west and more purple and white on the east. Europe is mostly purple. China, India, the Middle East, and Central America are mostly gold. There is a bright gold chain of lights stretching across the South Pacific toward Australia.

It's #WhereInTheWorld Wednesday! This image taken by #NOAA21 on April 11, 2026, features the largest island in Lake Michigan. With a permanent population of around 700, it is a popular spot for golfing and hiking.

As April draws near, we are looking at how ice cover on Lake Superior changed throughout the month of March. Imagery captured on clearer days from @NOAA's @JPSSProgram satellites shows the lake ice sloshing around the lake and shifting along the shoreline. #TimelapseTuesday

It's #WhereInTheWorld Wednesday! This reservoir, captured by the #NOAA21 🛰️ on Feb. 27, was created in 1969 by damming the Rio Grande River and is also fed by the Devils River. Today, it’s jointly managed by the U.S. and Mexico for flood control, water supply, recreation, and hydroelectric power.

This #NOAASatelliteShowdown contender is banding together. ☁️ Team Lake Effect! On Jan. 23, 2026, the #NOAA21 satellite shows clouds streaming off Lakes Superior and Michigan. Cold air over warmer lake water can turn them into narrow bands of snow. Like to vote!

It's #WhereInTheWorld Wednesday! This desert lake in California, seen by #NOAA21 on March 11, 2026, is extremely salty with highly alkaline water. Despite this, it supports a thriving ecosystem, where tiny brine shrimp and alkali flies feed on green algae. In turn, migratory birds depend on them as a vital food source.
