Happy 2025 from NASA Earth Observatory!

We are kicking off 2025 with much to look forward to but also much to look back on. In 2024, over 7.5 million readers visited our website to read our stories, and many millions more viewed our imagery on the NASAEarth social media channels and elsewhere. Since our founding in 1999 (2024 marked our 25^th anniversary), we have produced text and imagery for over 15,700 stories.

Clockwise from the upper left: From growing fruits and vegetables in China and flowers in the Netherlands to building new capital cities in Egypt and Indonesia, people have transformed the land.

Tidal currents stir up colorful swirls off the Kimberley Coast of Western Australia.
