It includes a quick start guide for educators and first-hand stories (blogs) for learners of all ages by NASA visualizers, scientists and educators.

Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.It all began with my fourth grade teacher, Mrs. Benner. Back then my school had a weather station and one day she had asked me to collect wind speed and temperature data. I soon found myself in charge of the morning weather forecast and soon this was my favorite part of the day. Little did I know that in the years that would follow, I’d pursue my passion for clouds and meteorology to become a research scientist at NASA. Working at NASA is every bit as cool as it sounds! Everyday is different and I always find myself working with new scientific tools to uncover mysteries about our planet Earth. Lately I’ve been studying the cryosphere, or the world’s frozen places, where I’m using scientific visualizations to understand the impacts of climate change in the Arctic. In particular I’m focusing on melting sea ice to understand how it affects Arctic cloud formation.Arctic clouds are made up of tiny liquid droplets and ice particles that form from condensation and then freezing of water vapor. Water vapor is a necessary ingredient for Arctic cloud formation, and evaporation from the Arctic Ocean can serve as an important source of water vapor. But when sea ice sits on the Arctic Ocean it acts as a lid that prevents evaporation and may limit Arctic cloud formation. Over the past decade the amount of Arctic sea ice has declined dramatically and we think this trend may be influencing Arctic cloud formation.I created a visualization showing the hypothesized response of clouds to melting in sea ice (below). The difference between the left panel, \"Current Conditions,\" and the right panel, \"Future Conditions,\" is that less sea ice in the future leads to more evaporation, and more evaporation leads to more water vapor and increased cloudiness. This hypothesis is where I base my research, using state-of-the-art NASA satellite instruments including CALIPSO and CloudSAT. || ", "hits": 36 }, { "id": 11239, "url": "https://svs.gsfc.nasa.gov/11239/", "result_type": "Produced Video", "release_date": "2013-05-02T00:00:00-04:00", "title": "Ring Around Our Planet", "description": "Within days of its launch on August 30, 2012, NASA's Van Allen Probes collected data that will rewrite textbooks.

Inner and outer radiation belts were discovered in 1958 with instruments on the very first U.S. satellites sent into space. But in September 2012 something happened that had never been recorded before: the particles that make up the belts settled into a new configuration, separating into three belts instead of two.

There is one data set for each year representing an aggregate of the approximate peak of the growing season (around August). The data was created using a sophisticated algorithm called LandTrendr. LandTrendr analyzes 'stacks' of Landsat scenes, looking for statistical trends in the data and filtering out noise. The algorithm evaluated data from more than 1,800 Landsat Thematic Mapper images, nearly 1 Terabyte of raw imagery, to define the life histories of each of more than 336 million pixels on the landscape. The resulting trends identify periods of stability and change that are displayed as colors.In these false color images, the colors represent types of land; for example, blue areas are forests; orange/yellow areas are agriculture; and, purple areas are urban. Each 'stack' is representative of a Landsat scene. There are 22 stacks stitched together to cover most of the U.S. Pacific Northwest.

While astronomers have found indirect evidence of these disturbances, the waves have so far eluded direct detection. Ground-based observatories designed to find them are on the verge of achieving greater sensitivities, and many scientists think that this discovery is just a few years away. Catching gravitational waves from some of the strongest sources — colliding black holes with millions of times the sun's mass — will take a little longer. These waves undulate so slowly that they won't be detectable by ground-based facilities. Instead, scientists will need much larger space-based instruments, such as the proposed Laser Interferometer Space Antenna, which was endorsed as a high-priority future project by the astronomical community. A team that includes astrophysicists at NASA's Goddard Space Flight Center in Greenbelt, Md., is looking forward to that day by using computational models to explore the mergers of supersized black holes. Their most recent work investigates what kind of \"flash\" might be seen by telescopes when astronomers ultimately find gravitational signals from such an event. To explore the problem, a team led by Bruno Giacomazzo at the University of Colorado, Boulder, and including Baker developed computer simulations that for the first time show what happens in the magnetized gas (also called a plasma) in the last stages of a black hole merger. In the turbulent environment near the merging black holes, the magnetic field intensifies as it becomes twisted and compressed. The team suggests that running the simulation for additional orbits would result in even greater amplification. The most interesting outcome of the magnetic simulation is the development of a funnel-like structure — a cleared-out zone that extends up out of the accretion disk near the merged black hole. The most important aspect of the study is the brightness of the merger's flash. The team finds that the magnetic model produces beamed emission that is some 10,000 times brighter than those seen in previous studies, which took the simplifying step of ignoring plasma effects in the merging disks. || ", "hits": 133 }, { "id": 10376, "url": "https://svs.gsfc.nasa.gov/10376/", "result_type": "Produced Video", "release_date": "2009-02-17T12:00:00-05:00", "title": "LRO's Team Spirit with Joanne Baker", "description": "The Lunar Reconnaissance Orbiter (LRO) is the first step to future missions to the Moon, Mars, and beyond.
