Shallow Lightning on Jupiter
Shallow Lightning on Jupiter
This animation takes the viewer on a simulated journey into Jupiter’s exotic high-altitude electrical storms. Get an up-close view of Mission Juno’s newly discovered “shallow lighting” flashes and dive into the violent atmospheric jet of the Nautilus cloud. The smallest white “pop-up” clouds on top of the Nautilus are about 100 km across. The ride navigates through Jupiter’s towering thunderstorms, dodging the spray of ammonia-water rain, and shallow lighting flashes. At these altitudes -- too cold for pure liquid water to exit – ammonia gas acts like an antifreeze that melts the water ice crystals flung up to these heights by Jupiter’s powerful storms – giving Jupiter an unexpected ammonia-water cloud that can electrify the sky. The animation was created by combining an image of high-altitude clouds from the JunoCam imager on NASA’s Juno spacecraft with a computer-generated animation.

HD 3d printing pizza on a contract from NASA HD
Systems and Materials Research Corporation (SMRC) is experimenting with 3D printing of food on a contract from NASA. Their pizza printer uses open source technology to "print" dough, sauce and cheese onto a platform with a heating element underneath.
The pizzas cannot be tasted yet because NASA requires clinical trials first!

Our Milky Way Galaxy: How Big is Space?
Our Milky Way Galaxy: How Big is Space?
When we talk about the enormity of the cosmos, it’s easy to toss out big numbers – but far more difficult to wrap our minds around just how large, how far, and how numerous celestial bodies really are. How big is our Milky Way Galaxy and how far away are exoplanets, the planets beyond our solar system?

The Ozone Hole: Closing the Gap
The Ozone Hole: Closing the Gap
In the 1980s, scientists began to realize that ozone-depleting chemicals, such as chlorofluorocarbon (CFCs), were creating a thin spot—a hole—in the ozone layer over Antarctica. Through an international effort to decrease the use of CFCs, the ozone layer is starting to mend, and scientists believe it should mostly recover by the middle of the 21st century. This series of satellite images shows the ozone hole on the day of its maximum depth from 1979 through 2018.

NASA's Garbage Patch Visualization Experiment
NASA's Garbage Patch Visualization Experiment
NASA created a visualization of the ocean garbage patches using data from floating, scientific buoys that NOAA has been distributing in the oceans for the last 35-years.
Video Credit: NASA's Scientific Visualization Studio
Complete transcript:
Hi, it’s Greg Shirah from NASA’s Scientific Visualization Studio. We wanted to see if we could visualize the so-called ocean garbage patches. We start with data from floating, scientific buoys that NOAA has been distributing in the oceans for the last 35-years represented here as white dots. Let's speed up time to see where the buoys go... Since new buoys are continually released, it's hard to tell where older buoys move to. Let's clear the map and add the starting locations of all the buoys… Interesting patterns appear all over the place. Lines of buoys are due to ships and planes that released buoys periodically.If we let all of the buoys go at the same time, we can observe buoy migration patterns. The number of buoys decreases because some buoys don't last as long as others. The buoys migrate to 5 known gyres also called ocean garbage patches. We can also see this in a computational model of ocean currents called ECCO-2.We release particles evenly around the world and let the modeled currents carry the particles. The particles from the model also migrate to the garbage patches. Even though the retimed buoys and modeled particles did not react to currents at the same times, the fact that the data tend to accumulate in the same regions show how robust the result is.
