A sea of colorful stars and galaxies appear to swim in the vast blackness of space around a hazy halo at centre stage. In the middle of the image, the fuzzy-looking bulb of light in a warm shade of yellow extends around a small bright spot, nestled within a thin light circle that appears to be drawn closely around it. As we follow the central halo’s rim outwards, its brightness dims and blends smoothly into its surroundings. Here, extended discs of shades ranging from a warm purple to golden yellow, and piercing dots of light with sharp diffraction spikes are spread evenly across the image.

Earth Information Center

For more than 50 years, NASA satellites have provided data on Earth's land, water, air, temperature, and climate. NASA's Earth Information Center allows visitors to see how our planet is changing in six key areas: sea level rise and coastal impacts, health and air quality, wildfires, greenhouse gases, sustainable energy, and agriculture.
