December Solstice 2018! Satellites See the Seasons Change from Space

The December solstice arrived today (Dec. 21), marking the start of winter in the Northern Hemisphere and the first day of summer for the Southern Hemisphere.

It’s also the shortest day of the year for those in the Northern Hemisphere, where the sun will now begin to shine a little bit longer by the day. Meanwhile, those in the Southern Hemisphere are experiencing the longest day of the year.

To celebrate the changing of the seasons, scientists with NASA’s Deep Space Climate Observatory (DSCOVR) shared a photo of Earth that the satellite captured on the eve of the solstice. NASA also shared a video that shows the changing tilt of Earth’s axis, which is responsible for the seasons.

DSCOVR, which launched in 2015, monitors Earth’s climate and space weather from the L1 Lagrange point, where it takes a new photo every 2 hours. You can keep up with the latest images from DSCOVR’s Earth Polychromatic Imaging Camera (EPIC) at
