Credit: NASA NASA released Tuesday the first episode of a new six-part podcast series for first-time space explorers to learn about the Sun. Ahead of the total solar eclipse in April, NASA’s Sun + Eclipse Series will focus on the sphere full of swirling magnetic fields and explosions of hot gases.
New episodes will post every Tuesday through April 23. The first episode is available at:
Sun Series: The Sun, Our Star – NASA
On April 8, 2024, a total solar eclipse will cross North America, passing over Mexico, the United States, and Canada. More than 32 million people will have the chance to witness, and a phenomenon the contiguous U.S. will not see again for 20 years.
The series will delve into the cultural connections and historical significance of solar studies. Listeners can prepare firsthand for the solar eclipse with insight from NASA experts along the path of totality. The series offers insight into research from NASA scientists, firsthand accounts from “eclipse chasers”, and how the agency protects astronauts and spacecraft during solar activity.
The series is part of NASA’s Curious Universe podcast. In each episode, hosts Padi Boyd and Jacob Pinter, bring listeners on science and space adventures. Explore the cosmos alongside astronauts, scientists, engineers, and other NASA experts in science, space exploration, and aeronautics.
NASA’s Sun + Eclipse Series is now available on Spotify, Apple Podcasts, Google Podcasts, and Soundcloud. Curious Universe is written and produced by a team at the agency’s Goddard Space Flight Center in Greenbelt, Maryland.

This side of a commemorative plate mounted on NASA’s Europa Clipper spacecraft features U.S. Poet Laureate Ada Limón’s handwritten “In Praise of Mystery: A Poem for Europa.” It will be affixed with a silicon microchip stenciled with names submitted by the public. NASA/JPL-Caltech When it launches in October, the agency’s Europa Clipper spacecraft will carry a richly layered dispatch that includes more than 2.6 million names submitted by the public.
Following in NASA’s storied tradition of sending inspirational messages into space, the agency has special plans for Europa Clipper, which later this year will launch toward Jupiter’s moon Europa. The moon shows strong evidence of an ocean under its icy crust, with more than twice the amount of water of all of Earth’s oceans combined. A triangular metal plate on the spacecraft will honor that connection to Earth in several ways.
At the heart of the artifact is an engraving of U.S. Poet Laureate Ada Limón’s handwritten “In Praise of Mystery: A Poem for Europa,” along with a silicon microchip stenciled with more than 2.6 million names submitted by the public. The microchip will be the centerpiece of an illustration of a bottle amid the Jovian system – a reference to NASA’s “Message in a Bottle” campaign, which invited the public to send their names with the spacecraft.
A ‘Golden Record’ for Europa
Made of the metal tantalum and about 7 by 11 inches (18 by 28 centimeters), the plate features graphic elements on both sides. The outward-facing panel features art that highlights Earth’s connection to Europa. Linguists collected recordings of the word “water” spoken in 103 languages, from families of languages around the world. The audio files were converted into waveforms (visual representations of sound waves) and etched into the plate. The waveforms radiate out from a symbol representing the American Sign Language sign for “water.”
To hear audio of the spoken languages and see the sign, go to: go.nasa.gov/MakeWaves.
In the spirit of the Voyager spacecraft’s Golden Record, which carries sounds and images to convey the richness and diversity of life on Earth, the layered message on Europa Clipper aims to spark the imagination and offer a unifying vision.
The art on this side of the plate, which will seal an opening of the vault on NASA’s Europa Clipper, features waveforms that are visual representations of the sound waves formed by the word “water” in 103 languages. At center is a symbol representing the American Sign Language sign for “water.”NASA/JPL-Caltech “The content and design of Europa Clipper’s vault plate are swimming with meaning,” said Lori Glaze, director of the Planetary Science Division at NASA Headquarters in Washington. “The plate combines the best humanity has to offer across the universe – science, technology, education, art, and math. The message of connection through water, essential for all forms of life as we know it, perfectly illustrates Earth’s tie to this mysterious ocean world we are setting out to explore.”
Reaching Out to the Cosmos
In 2030, after a 1.6-billion-mile (2.6-billion-kilometer) journey, Europa Clipper will begin orbiting Jupiter, making 49 close flybys of Europa. To determine if there are conditions that could support life, the spacecraft’s powerful suite of science instruments will gather data about the moon’s subsurface ocean, icy crust, thin atmosphere, and space environment. The electronics for those instruments are housed in a massive metal vault designed to protect them from Jupiter’s punishing radiation. The commemorative plate will seal an opening in the vault.
Because searching for habitable conditions is central to the mission, the Drake Equation is etched onto the plate as well – on the inward-facing side. Astronomer Frank Drake developed the mathematical formulation in 1961 to estimate the possibility of finding advanced civilizations beyond Earth. The equation has inspired and guided research in astrobiology and related fields ever since.

These particular frequencies match the radio waves emitted in space by the components of water and are known by astronomers as the “water hole.” On the plate, they are depicted as radio emission lines.
Finally, the plate includes a portrait of one of the founders of planetary science, Ron Greeley, whose early efforts to develop a Europa mission two decades ago laid the foundation for Europa Clipper.
“We’ve packed a lot of thought and inspiration into this plate design, as we have into this mission itself,” says Project Scientist Robert Pappalardo of NASA’s Jet Propulsion Laboratory in Southern California. “It’s been a decades-long journey, and we can’t wait to see what Europa Clipper shows us at this water world.”
Once assembly of Europa Clipper has been completed at JPL, the spacecraft will be shipped to NASA’s Kennedy Space Center in Florida in preparation for its October launch.
More About the Mission
Europa Clipper’s main science goal is to determine whether there are places below Jupiter’s icy moon, Europa, that could support life. The mission’s three main science objectives are to determine the thickness of the moon’s icy shell and its surface interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
