Here's what America's recent snowstorms looked like from space

The Midwest and Northeast United States have been blanketed by snow and ice in the past week, thanks to a surge of cold air sweeping down from the Arctic.

And here's what the aftermath looked like from above, courtesy of NASA's Earth Observatory. The stunning pic below was captured on January 13 by the agency's Terra satellite, which passes north-to-south across the equator every morning:

Winter storms brought snow and ice to a large portion of the U.S. Midwest and Northeast. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired top image on January 13, 2015.

And here's a January 10 pic from NASA's Aqua satellite, which passes south-to-north over the equator in the afternoon (taken together, the two can take images of the entire Earth's surface every 1 to 2 days):

Note that the Great Lakes don't freeze over entirely in the winter — unlike ponds — mainly because they're so deep. As of January 14, about 32 percent of the Great Lakes were covered in ice. Lake Eerie, in particular, has a lot of ice after a deep freeze. (Out in Lake Michigan, meanwhile, snow has been falling on top of the ice, acting as a heat insulator and making it slushier — so authorities have been warning people not to go out.)

In a typical winter, up to 30 to 40 percent of the Great Lakes can freeze over by March, with the ice shifting around from place to place with the wind. And occasionally you get really big extremes: In March 2014, thanks to unusually cold weather, a whopping 92.2 percent of the lakes were covered in ice, the second-most on record.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple reasons that we can't rely only on ads and subscriptions to keep the lights on.

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. We can’t do that if we have a paywall.

That’s why we also turn to you, our readers, to help us keep Vox free. If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today?
