Explanation: Big, beautiful spiral galaxy NGC 7331 is often touted as an analog to our ownMilky Way. About 50 million light-years distant in the northern constellation Pegasus, NGC 7331 was recognized early on as a spiral nebulaand is actually one of the brighter galaxies notincluded in Charles Messier''s famous 18th century catalog. Since the galaxy''s disk is inclined to our line-of-sight, long telescopic exposures often result in an image that evokes a strong sense of depth. The effect is further enhanced in this sharp image from a small telescope by galaxies that lie beyond the gorgeous island universe. The most prominent background galaxies are about one tenth theapparent size of NGC 7331 and so lie roughly ten times farther away. Their close alignment on the sky with NGC 7331 occurs just by chance. Seen through faint foreground dust clouds lingering above the plane of Milky Way, this visual grouping of galaxies is known as theDeer Lick Group.
This summer, 30 research projects were launched by recent college graduates and early career professionals as part of our DEVELOP program. The aim is to use our satellite observations of Earth to address an environmental or public policy issue. And they have just 10 weeks to do it! On Aug. 10, 2016, the “DEVELOPers” gathered at our Headquarters in Washington, DC to showcase their results. So, how can Earth observations solve real-world problems? Let’s take a look:
1. They help land managers identify the locations of invasive species.
Austin Haney, DEVELOP project co-lead at University of Georgia, has seen first-hand how an invasive species can affect the ecosystem of Lake Thurmond, a large reservoir that straddles the border between Georgia and South Carolina. Birds in the area “behave visibly different,” he said, after they consume a toxic cyanobacteria that lives on Hydrilla verticillata, an invasive aquatic plant. Ingesting the toxin causes a neurodegenerative disease and ultimately death. Scores of birds have been found dead near lake areas where large amounts of the toxin-supporting Hydrilla grow. To help lake managers better address the situation, Haney and project members developed a tool that uses data from the Landsat 8 satellite to map the distribution of Hydrilla across the lake.

2. They help identify wildlife habitat threatened by wildfires.
Maps that depict habitat and fire risk in eastern Idaho previously stopped short of Craters of the Moon National Monument and Preserve, where shrubs and grasses transition to a sea of ankle-twisting basalt. But the environment is not as inhospitable as it first appears. Throughout the monument there are more than 500 kipukas —pockets of older lava capable of supporting some vegetation. That means it is also prone to burning. Project lead Courtney Ohr explained how her team used data from the Landsat 8 and Sentinel-2 satellites to develop a model that can simulate the area’s susceptibility to wildfires. Decision makers can use this model to monitor the remote wildlife habitat from afar.

3. In conjunction with Instagram, they help find seaweed blooms
Who knew that Instagram could be a tool for science? One DEVELOP team searched for photographs of massive seaweed (sargassum) blooms in the Caribbean, mapped the locations, and then checked what satellites could see. In the process, they tested two techniques for finding algae and floating vegetation in the ocean.

4. They help conserve water by reducing urban stormwater runoff.
Atlanta’s sewer system is among the nation’s most expensive. Yet, the city still struggles with stormwater. It’s an uphill climb as new construction paves over more of the city, hindering its ability to absorb rain. The University of Georgia DEVELOP team partnered with The Nature Conservancy to address the problem.
Using satellite imagery, the team was able to pinpoint areas well-poised to capture more of the city’s runoff. They identified 17 communities ripe for expanding green infrastructure and reforestation. The team used the Land-Use Conflict Identification Strategy and Soil and Water Assessment Tool models and Landsat and Terra satellite data. Their analysis provides local groups with a working picture of the city’s water resources.

5. They show the spread of the mite eating away Puerto Rico’s palm trees.
The red palm mite has devastated Puerto Rico’s trees in recent years. The insect chewed its way through coconut palms, bananas, and plantains on the island in the recent decade. Its spread has hurt crops across the Caribbean.
A DEVELOP team led by Sara Lubkin analyzed satellite imagery to track the mites’ rapid spread from 2002. The team mapped changes to vegetation, such as yellowing, and differences in canopy structure. They made use of imagery from Landsat, Hyperion, IKONOS, and aerial views. Their work can be used to mitigate current mite infestations and monitor and prevent future ones.

6. They evaluate landslide-prone areas in the developing world
One team of DEVELOPers took on several projects to aid people in developing nations. This team from Alabama examined satellite imagery to find past landslides in the African nation of Malawi. Factors such as flooding after long periods of drought have made the country increasingly prone to landslides. Blending maps of the landscape, rainfall data, and population centers, the young researchers assessed the areas most at risk—and most in need of education and support—from landslides.

What strange world is this? Earth. In the foreground of the featured image are thePinnacles, unusual rock spires in Nambung National Park in Western Australia. Made of ancient sea shells (limestone), how these human-sizedpicturesque spires formed remains unknown. In the background, just past the end of the central Pinnacle, is a bright crescent Moon. The eerie glow around the Moon is mostly zodiacal light, sunlight reflected by dust grains orbiting between the planets in the Solar System. Arching across the top is the central band of our Milky Way Galaxy. Many famous stars and nebula are also visible in the background night sky. The featured 29-panel panorama was taken and composed last September after detailed planning that involved the Moon, the rock spires, and their corresponding shadows. Even so, the strong zodiacal light was a pleasant surprise. Image Credit: Michael Goh
Just like many organizations, the style and logos can change over time. You are probably most familiar with our “meatball” logo. No, unfortunately this does not refer to the delicious food. This logo (below) is our most popular symbol, and dates back to 1959.
But, we’ve also had other insignia that represented our organization throughout the years.
The “worm” logo (below) was used by the agency from 1975 until 1992. The organization wanted to create a more “modern” logo, which resulted in the unique type style of the “worm” logo.
Even though this logo was retired in 1992, the Graphics Standards Manual is still available online HERE.
You can also read up about the emblems, logos and insignia used by NASA throughout the years in a new e-Book available for free HERE.

Want to take a relaxing interstellar vacation? Consider visiting Kepler-16b, a world in a binary star system. In fact Kepler-16b is the first discovered circumbinary planet. It was detected in a wide 229 day orbit around a close pair of cool, low-mass stars some 200 light-years away. The parent stars eclipse one another in their orbits, observed as a dimming of starlight. But Kepler-16b itself was discovered by following the additional very slight dimming produced during its transits. Like sci-fi planet Tatooine of Star Wars fame, two suns would set over its horizon. Still, Kepler 16b is probably not a Tatooine-like terrestrial desert world. Instead, Kepler 16b is thought to be a cold, uninhabitable planet with about the mass of Saturn and a gaseous surface ... so plan to dress accordingly. Or, choose another Visions of the Future vacation destination. For image credit and copyright guidance, please visit the image websitehttp://antwrp.gsfc.nasa.gov/apod/ap160220.html
