NASA HEAT Student Activity Featured in TIME’s Top 100 Photos of 2024
On April 8, 2024, tens of millions experienced a solar eclipse from Mexico through the United States and into Canada. Astronomers, educators, and organizations had been preparing the public for this grand celestial event. Learning from engagement experiences in 2017, the NASA Heliophysics Education Activation Team (NASA HEAT) promoted an activity called “Eclipse Essentials: Safe and Stylish Solar Viewing Glasses.” The activity was first tested in Albuquerque, New Mexico during the Balloon Fiesta around the October 2023 annular eclipse. Using solar viewing glasses, a paper plate, some drawing and decoration supplies, visitors – minors and adults alike – crowded around the heliophysics tables in the NASA tent. That positive experience led NASA HEAT to modify and perfect the design of their “face shield” activity before offering trainings to numerous educators and outreach personnel in the weeks leading up to the April 2024 engagement events.
Note: The glasses and the art activity are not only useful for solar eclipses. They can be used anytime to safely observe the Sun. While it is never safe to look directly at the sun with unprotected eyes, eclipse glasses are perfect for observing sunspots!
One proof of positive impact can be found at the Myers Elementary School in Grand Blanc, Michigan. Students from two kindergarten classes, escorted outside by their teachers Amy Johnston and Wendy Sheridan, stared toward the sky with their solar viewing glasses using paper plates to watch the solar eclipse on Monday, April 8, 2024. The paper plates, which helped provide additional safety measures to protect their eyes, were attached to solar eclipse glasses and decorated by each student in their classrooms as a project leading up to the big day. A photo of the students was so captivating that multiple media outlets shared it on or shortly after the day of the eclipse.
The global media brand, TIME, selected a photo of these kindergarten students wearing their NASA HEAT-designed solar eclipse-viewing “face shields” during the April 8th solar eclipse as one of “TIME’s Top 100 Photos of 2024”. When sharing about the top 100 photos on Instagram, TIME had this to say:
“Every year the TIME photo department sits down to curate the strongest images that crossed our path over the previous 12 months. And every year, sitting with the images, we find ourselves mulling the ways this collection feels heavier than the last, how the year produced images unlike what we’ve seen before.
But this year something else, a tautness, runs through the collection – the tension of conflict, the anxiety over outcome, anticipation of excitement or in possibility. Somehow, these photographers are able to capture that coiled feeling and hold it within the four walls of a frame. Be it by impeccable timing or intentional framing, they have created a time capsule that feels as if it’s about to be opened.”

A portion of Webb’s 2023 observation of Wolf-Rayet 140. Credits:
Image: NASA, ESA, CSA, STScI; Science: Emma Lieb (University of Denver), Ryan Lau (NSF NOIRLab), Jennifer Hoffman (University of Denver) Astronomers have long tried to track down how elements like carbon, which is essential for life, become widely distributed across the universe. Now, NASA’s James Webb Space Telescope has examined one ongoing source of carbon-rich dust in our own Milky Way galaxy in greater detail: Wolf-Rayet 140, a system of two massive stars that follow a tight, elongated orbit.
As they swing past one another (within the central white dot in the Webb images), the stellar winds from each star slam together, the material compresses, and carbon-rich dust forms. Webb’s latest observations show 17 dust shells shining in mid-infrared light that are expanding at regular intervals into the surrounding space.
Image A: Compare Observations of Wolf-Rayet 140 (MIRI Images)
Two mid-infrared images from NASA’s James Webb Space Telescope of Wolf-Rayet 140 show carbon-rich dust moving in space. At right, the two triangles from the main images are matched up to show how much difference 14 months makes: The dust is racing away from the central stars at almost 1% the speed of light. These stars are 5,000 light-years away in our own Milky Way galaxy. Image: NASA, ESA, CSA, STScI; Science: Emma Lieb (University of Denver), Ryan Lau (NSF NOIRLab), Jennifer Hoffman (University of Denver) “The telescope not only confirmed that these dust shells are real, its data also showed that the dust shells are moving outward at consistent velocities, revealing visible changes over incredibly short periods of time,” said Emma Lieb, the lead author of the new paper and a doctoral student at the University of Denver in Colorado.
Every shell is racing away from the stars at more than 1,600 miles per second (2,600 kilometers per second), almost 1% the speed of light. “We are used to thinking about events in space taking place slowly, over millions or billions of years,” added Jennifer Hoffman, a co-author and a professor at the University of Denver. “In this system, the observatory is showing that the dust shells are expanding from one year to the next.”
Like clockwork, the stars’ winds generate dust for several months every eight years, as the pair make their closest approach during a wide, elongated orbit. Webb also shows how dust formation varies — look for the darker region at top left in both images.
Video A: Fade Between 2022 and 2023 Observations of Wolf-Rayet 140
This video alternates between two mid-infrared light observations from NASA’s James Webb Space Telescope of Wolf-Rayet 140. Over only 14 months, Webb showed the dust in the system has expanded. This two-star system has sent out more than 17 shells of dust over 130 years. Video: NASA, ESA, CSA, STScI.; Science: Emma Lieb (University of Denver), Ryan Lau (NSF NOIRLab), Jennifer Hoffman (University of Denver) Video B: Stars’ Orbits in Wolf-Rayet 140 (Visualization)
When the two massive stars in Wolf-Rayet 140 swing past one another, their winds collide, material compresses, and carbon-rich dust forms. The stronger winds of the hotter star in the Wolf-Rayet system blow behind its slightly cooler (but still hot) companion. The stars create dust for several months in every eight-year orbit.
Video: NASA, ESA, CSA, Joseph Olmsted (STScI). The telescope’s mid-infrared images detected shells that have persisted for more than 130 years. (Older shells have dissipated enough that they are now too dim to detect.) The researchers speculate that the stars will ultimately generate tens of thousands of dust shells over hundreds of thousands of years.
“Mid-infrared observations are absolutely crucial for this analysis, since the dust in this system is fairly cool. Near-infrared and visible light would only show the shells that are closest to the star,” explained Ryan Lau, a co-author and astronomer at NSF NOIRLab in Tuscon, Arizona, who led the initial research about this system. “With these incredible new details, the telescope is also allowing us to study exactly when the stars are forming dust — almost to the day.”
The dust’s distribution isn’t uniform. Though this isn’t obvious at first glance, zooming in on the shells in Webb’s images reveals that some of the dust has “piled up,” forming amorphous, delicate clouds that are as large as our entire solar system. Many other individual dust particles float freely. Every speck is as small as one-hundredth the width of a human hair. Clumpy or not, all of the dust moves at the same speed and is carbon rich.
The Future of This System
What will happen to these stars over millions or billions of years, after they are finished “spraying” their surroundings with dust? The Wolf-Rayet star in this system is 10 times more massive than the Sun and nearing the end of its life. In its final “act,” this star will either explode as a supernova — possibly blasting away some or all of the dust shells — or collapse into a black hole, which would leave the dust shells intact.
Though no one can predict with any certainty what will happen, researchers are rooting for the black hole scenario. “A major question in astronomy is, where does all the dust in the universe come from?” Lau said. “If carbon-rich dust like this survives, it could help us begin to answer that question.”
“We know carbon is necessary for the formation of rocky planets and solar systems like ours,” Hoffman added. “It’s exciting to get a glimpse into how binary star systems not only create carbon-rich dust, but also propel it into our galactic neighborhood.”
These results have been published in the Astrophysical Journal Letters and were presented in a press conference at the 245th meeting of the American Astronomical Society in National Harbor, Maryland.
The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.
