PIPER Infographic

This infographic shows many factoids about the PIPER (Primordial Inflation Polarization Explorer) balloon mission. At the top, there is part of an image of the cosmic microwave background with the text, “The cosmic microwave background (CMB) is heat left over from the big bang and is the oldest light we can see in the universe.” Just below that, near a circular, bright “explosion” is the text, “Scientists are studying the CMB for proof that the universe expanded rapidly immediately after the big bang.” Next is an image of two circles of yellow lines that look like 8-pointed pinwheels that would swirls in opposite directions with text, “This process, called inflation, should have created gravitational waves. If so, light from the CMB should contain a distinct twisting polarization pattern called B-mode.” There is a cut-out line drawing of the PIPER payload with the silhouette of a person standing next to it, showing that it is about two persons’ high. The text says, “PIPER is a microwave telescope flown on a high-altitude balloon. The instrument has twin telescopes in a hot-tub-sized container of liquid helium.” Next there is text with icicles below it that reads, “Liquid helium keeps the instrument at -452 degrees Fahrenheit (-269 Celsius).” Near a map of the United States with a telescope by Maryland and a lightbulb near California is the text, “The detectors on PIPER could spot a 60-watt incandescent light bulb in California from PIPER's base of operations at NASA's Goddard Space Flight Center in Maryland.” A silhouette of a hippopotamus accompanies the text, “PIPER's total weight, including instrument, balloon and ballast, is about 8,000 pounds (3,600 kilograms), as much as a full-grown male hippopotamus.” An illustration of the fully inflated balloon appears with the text, “Width of fully inflated balloon: 430 feet (130 meters).” Underneath the balloon are three houses. The text nearby explains, “The balloon expands to approximately 40 million cubic feet (1.1 million cubic meters) when it reaches maximum altitude. It's made from polyethylene film comparable in thickness to ordinary plastic sandwich wrap.” A drawing of Australia, Texas and New Mexico is accompanied by the text, “Flights are planned from Ft. Sumner, New Mexico, Palestine, Texas and Alice Springs, Australia. Overnight flights from these three locations will allow PIPER to cover 85 percent of the sky.” And finally, a commercial airplane near the bottom has text, “PIPER's maximum altitude is about 120,000 feet (36,000 meters). That's more than three times the cruising altitude of a commercial airplane.”

The Primordial Inflation Polarization Explorer (PIPER) is a NASA scientific balloon mission that has flown at the edge of Earth’s atmosphere to study twisty patterns of light in the universe’s “baby picture.” This infographic highlights some facts about PIPER’s instruments, capabilities, and goals.

On a black background is a smattering of light sources like confetti on the floor after a party. Some appear as small dots in the background in blue, white, yellow, and red. Some are larger with spiral structures or are ovals and circles. A few large white spots have orange halos, and appear larger than the rest. There’s one bright white spot with spikes of light, which is a relatively nearby star on this sea of distant galaxies.

Two cloudy nebula appear in this image, each in shades of green, yellow and red. One appears to blast across the image from the lower left just about to the top of the image just the right of center. At the top end the nebua had a bright white spot with a red halo, and trailing behind to the lower left of the image is a semi-transparent green cloud looking like a dress trailing behind. Taking up the lower right portion of the image is a compact green bundle of clouds, with just a thin strip of black sky between the two nebulae.

This view of a starry sky is bathed in red cloud-like structures. There is a bright grouping of stars just above and to the left of center in the image. These stars are bright white with large diffraction spikes, long lines like an asterisk over each star. The background changes to an electric green behind the concentration of stars. Lines in the image show where magnetic fields run. They run left to right over the main grouping of stars, but gradually change to be tilted from bottom left up to the right just below the grouping of stars.

This GIF shows a representation of a gamma-ray flare from an active galaxy. Throughout the animation, circles appear that then expand like raindrops on water in varying sizes and shades of magenta. The smaller circles with lighter colors represent lower energy gamma rays, and the larger circles with darker colors are higher energy gamma rays. The animation starts with just a few of these drops across the image, with the density increasing and more large drops appearing in the center of the image toward the end, until the image is nearly filled with the expanding circles.

Taking up the center of the photo is one of NICER’s X-ray concentrators which is formed from concentric cylindrical mirrors that look like a vinyl record with very deep grooves. On top of the concentrator is a metal structure with a hexagonal plate in the center that has thin bars extending from each of the six corners, looking like a spiderweb. This one concentrator is surrounded by five others, which are only partially seen. Along the top quarter of the image is a clear window that reflects rectangular light and has a series of small holds in a grid across the bottom edge. Some parts of the central concentrator and the one to the upper right of it are bathed in purple light.

This illustration explains the weak force, one of the four fundamental forces in the universe.
More
This infographic is done mostly in shades of blue. At the top left is the title: "Weak Force." Below that is a block of text that reads: "The weak force can change a quark from one type to another: from up to down. That change could turn a proton into a neutron or vice versa. This process would also produce a neutrino and an electron or anti-electron through a process called beta decay." Below and to the right of the text is an illustration of a blue proton and a red neutron with pop outs. The proton is on the left. Its pop out shows a cluster of two yellow up quarks and one pink down quark. An arrow is pointing to one of the up quarks. The pop up for the neutron shows a cluster of two pink down quarks and one yellow up quark. An arrow points to one of the down quarks, indicating that it flipped from an up quark, which changed the proton into a neutron.

The ringed planet Saturn is seen on a stark black background. The round planet has bands of pale yellow, tan, and brown that appear as stripes across its surface, with the brightest and broadest band around the center of the planet and varying sizes of bands moving up to the top. Encircling the planet is a system of rings which are seen in front of the planet with part of the rings hidden behind the back. The rings also have bands of color ranging from pale blue to white and dusty tan with a few black areas showing gaps between the rings.

This image shows an oval that represents the whole sky if you folded it out onto a flat piece of paper. The oval is dotted with many regions ranging from blue, green, yellow and red in color. While the image looks chaotic, the blue regions are nearly always surrounded by green. The yellow are embedded in the green, and red embedded in the yellow. These show temperature differences in the early universe, which ultimately lead us to see where matter clumped together to form the structures we see today.

Composite image of the Swan Nebula with data from NASA's SOFIA, Herschel Space Telescope, and Spitzer Space Telescope.
More
Against a starry background sits a nebula that resembles the neck and head of a swan who is looking to the left. The cloudy nebula is a dark red on the edges that would be the right side of the swan’s neck and top of its head. This fades into a pale yellow on the left side of the swan’s neck and the bottom of the head and beak. Inside the crook of the neck there is a semi-transparent blue cloud. All of this is on a black, starry background.
