Plant life cycle shows a breathing Earth

NASA mapped the annual cycle of all plant life on the planet in this animated map. Satellite instruments reveal the yearly cycle of plant life on the land and in the water. On land, the images represent the density of plant growth, while in the oceans they show the chlorophyll concentration from tiny, plant-like organisms called phytoplankton. From December to February, during the northern hemisphere winter, plant life in the...

The Sun in ultra-HD

x Daang, NASA. Using images of the sun taken in space, NASA constructed this super-detailed view of what the star looks like. In space, NASA's Solar Dynamics Observatory, or SDO, keeps an eye on our nearest star 24/7. SDO captures images of the sun in 10 different wavelengths, each of which helps highlight a different temperature of solar material. In this video, we experience SDO images of the sun in...

Pluto reflectance map: Whale and the Donut

Using images taken by New Horizons between June 27 and July 3, this is the latest NASA map informally named the Whale and the Donut. Now, use your imagination here (because space!). The dark area on left is the whale, representing about 1,860 miles of length, and the tail in the left corner is cupping the donut. Hopefully we'll get a better look come next week. I'm guessing they're an...

Journey to Pluto

The New Horizons spacecraft launched on January 19, 2006 and is set to fly by Pluto next week on July 14, 2015. The New York Times provides a short documentary on the journey and the hope for what the flyby provides. It's a combination of researcher interviews and scientific graphics. So good, even if you don't follow space-related news. Set aside the 13 minutes and 21 seconds to watch the...

Life cycle of Earth’s carbon dioxide

The Cartography and Geovisualization Group at Oregon State University and NASA visualized a one-year life cycle of carbon dioxide in an interactive video map. The visualization is a product of a simulation called a "Nature Run." The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then left to run on its own and simulate the...

Mapping ice layers with radar data

I don't know exactly how much data NASA has in the bank, but I think it's a lot. Explained in the video below, they estimated the age of ice layers in Greenland by flying a plane over the Greenland Ice Sheet and pulsing radar to gather information. Tags: ice, NASA, weather

The first photo of the United States by NASA satellite

In 1974, NASA published their first satellite photo of the contiguous United States by stitching together a bunch of individual images. A giant photo map of the contiguous 48 states of the United States, the first ever assembled from satellite images, completed for NASA by the U.S. Department of Agriculture Soil Conservation Service Cartographic Division. The map is 10 by 16 feet, is composed of 595 cloud-free black-and-white images returned...
