Have you ever wondered what space sounds like? Well, it turns out that space is full of waves, but they don’t make any sound because there’s no air or other medium for the waves to travel through. However, scientists have found a way to turn these waves into sounds we can hear!
Our sun, a yellow dwarf star, is constantly sending out energy in the form of radiation. This radiation covers the entire electromagnetic spectrum, from x-rays to radio waves. Imagine it like the sun breathing out energy from its elements, like hydrogen and iron. A composer named Robert Alexander took these solar waves and turned them into music, creating a unique soundtrack for our cosmic journey.
The Earth is constantly being hit by a stream of energized particles from the sun, known as the solar wind. This flow of energy is like a cosmic breeze that expands our solar system. Scientists have translated this solar wind into sound, allowing us to “hear” what it might be like if we could listen to these particles. The sound is set at 20 Hz and beyond, creating a fascinating audio experience.
High above Earth’s surface, there’s a field of plasma that creates a sound similar to a “whale song.” This sound comes from the Van Allen belts, which are part of Earth’s magnetic shield. These belts protect us by deflecting the energized particles from the solar wind. If our ears could pick up radio waves, we would hear the Van Allen chorus, an invisible sound that only needs a medium to be complete.
There’s a piece of music called “Mandala” that expresses the harmony of the planets, including Pluto. Each planet’s orbit creates a rhythm, forming a cosmic melody that is the longest palindrome ever conceived—ten to the sixty-fourth notes long! This melody is a beautiful representation of the universe’s rhythm.
It’s fascinating to think about why humans, a single species of apes on a blue planet orbiting a yellow star, created music. We use songs for communication and dreaming, going beyond just surviving. Through music, we’ve found ways to extend our senses and create sound from space. It makes us wonder, “If the universe had a voice, what song would it sing?”
So next time you look up at the stars, remember that there’s a whole symphony playing out there, just waiting for us to listen.
Imagine you are a composer like Robert Alexander. Use a digital audio workstation or an online music creation tool to create your own soundtrack based on the concept of space waves. Think about how different elements like the sun, solar wind, and planets might sound. Share your composition with the class and explain your creative choices.
Conduct an experiment to understand how sound waves travel. Use a speaker and a balloon to demonstrate how sound needs a medium to travel. Then, listen to recordings of the solar wind translated into sound. Discuss how scientists convert these waves into audible sounds and what challenges they might face.
Work in groups to simulate the Van Allen belts using magnets and iron filings. Observe how the magnetic field deflects the filings, similar to how the belts protect Earth from solar wind. Discuss how this invisible shield is crucial for life on Earth and what it would be like if we could hear the “whale song” of the Van Allen belts.
Explore the concept of planetary rhythms by creating a rhythm pattern based on the orbits of the planets. Use percussion instruments or clapping to represent each planet’s orbit. Try to create a group performance that reflects the cosmic melody of the solar system, inspired by the “Mandala” music piece.
Write a short essay or poem reflecting on the idea of the universe having a voice. Consider what song it might sing and what emotions or messages it would convey. Share your reflections with the class and discuss how music helps us connect with the cosmos and each other.

A sound is a wave in a medium, whether solid, liquid, or gas. In the vacuum of space, there is no sound. However, space is filled with waves that, without a medium to travel through, remain beyond our hearing. Until now.
Throughout our galaxy and in galaxies far beyond, stars emit radiation across the entire electromagnetic spectrum. The music you hear comes from our sun, a yellow dwarf that releases energy from x-rays to radio waves, akin to breath exhaling from its ionized elements, from hydrogen to iron. Robert Alexander composed the soundtrack for this segment of our cosmic journey.
Satellite observations of energized carbon, both within and at the edge of the sun, are translated onto a musical scale, with the sun’s rotation serving as its metronome. [music playing]
Earth is in the path of a constant stream of energized solar particles, like a stellar breeze interacting with an extraterrestrial weather vane. This flow of energy expands our solar system. What if we could experience this current? This is what we might perceive if the solar wind were translated into sound, at 20 Hz and beyond. [music playing]
The interstellar “whale song” you hear originates from a field of plasma thousands of kilometers above Earth’s surface. The Van Allen belts, which form part of the magnetic shield that protects Earth from the solar wind, deflect energized particles away from us. If we had radio antennas for ears, the Van Allen chorus would be detectable within the audible range of human hearing—a source of invisible sound, only lacking a medium to complete it.

With this piece, “Mandala,” we can express the harmony of the planets, including Pluto, as musical notes, with their orbital periods creating a rhythm and forming the longest palindrome ever conceived—ten to the sixty-fourth notes of an unrepeating cosmic melody.
No one knows why a single species of apes on a blue planet orbiting a yellow star created music—songs for communication and dreaming beyond mere survival. Through music, we have found ways to extend beyond our natural senses; we have created sound from space. This prompts us to ask, “If the universe had a voice, what song would it sing?”

Space – The vast, seemingly infinite expanse that exists beyond the Earth’s atmosphere, where stars, planets, and other celestial bodies are located. – Astronomers use telescopes to study the mysteries of space and understand the universe better.
Waves – Disturbances that transfer energy from one place to another, often through a medium like air or water. – In physics class, we learned how sound waves travel through the air to reach our ears.
Sound – A type of energy that is produced by vibrating objects and travels through a medium such as air, water, or solids. – The sound of the violin filled the concert hall, captivating the audience.
Sun – The star at the center of our solar system that provides light and heat to the planets orbiting it. – The sun’s energy is essential for life on Earth, driving weather patterns and supporting photosynthesis.
Solar – Relating to or derived from the sun, especially in terms of energy. – Solar panels convert sunlight into electricity, providing a renewable energy source.
Wind – The movement of air caused by differences in atmospheric pressure, often used as a source of renewable energy. – Wind turbines harness the power of the wind to generate electricity.
Earth – The third planet from the sun in our solar system, home to diverse life forms and ecosystems. – Scientists study the Earth’s climate to understand how it is changing over time.
Music – An art form and cultural activity involving the creation of sound through instruments or vocal techniques, often structured in time. – The music played by the orchestra was both beautiful and inspiring.
Harmony – The combination of different musical notes played or sung simultaneously to produce a pleasing sound. – The choir’s harmony was perfect, creating a rich and full sound that resonated with the audience.
Planets – Celestial bodies that orbit a star, such as the sun, and are massive enough to be rounded by their own gravity. – The planets in our solar system each have unique characteristics and atmospheres.
