    "description": "A healthy plant is a glowing plant. That's because healthy plants that engage in photosynthesis—convert sunlight to energy—also emit fluorescent light. It's the same physical process that makes everyday objects glow in the dark. While human eyes are unable to detect the faint glow from plants, satellites hundreds of miles above Earth are up to the task. A team of researchers led by NASA scientists identified the fluorescence fingerprint in data collected by an instrument on a European meteorological satellite. A visualization of the data, released in 2013, allows scientists for the first time to see global changes in terrestrial plant fluorescence over the course of a month. That means a front-row seat to track the northward migration of plant blooming during the Northern Hemisphere springtime, as well as the shut down in fall—even before changing leaf colors indicate a seasonal shift is amiss. Watch the visualization for a tour of plant fluorescence around the world. || ",

            "description": "NASA scientists have discovered a new way to use satellites to measure what's occurring inside Earth's land plants at a cellular level.During photosynthesis, plants emit what is called fluorescence – a form of light invisible to the naked eye but detectable by satellites orbiting hundreds of miles above Earth. NASA scientists established a method to turn this satellite data into global maps of the subtle phenomenon in more detail than ever before.The new maps – produced by Joanna Joiner of NASA's Goddard Space Flight Center in Greenbelt, Md., and colleagues – provide a 16-fold increase in spatial resolution and a 3-fold increase in temporal resolution over the first proof-of-concept maps released in 2011. Improved global measurements could have implications for farmers interested in early indications of crop stress, and ecologists looking to better understand global vegetation and carbon cycle processes.\"For the first time, we are able to globally map changes in fluorescence over the course of a single month,\" Joiner said. \"This lets us use fluorescence to observe, for example, variation in the length of the growing season.\" || ",
