The Stellar Music project in summary - take musical notes generated mathematically from a star, arrange them into a beautiful tune, and then use your imagination to think of unique ways to illustrate the music. To discover how the music was created visit the blog: innovaspace.org/blog/stellar-music
- Star used = Delta Cephei, part of the constellation Cepheus

Enjoy the cosmic music 🌟🌟🌟
In this week that saw the world celebrate International Women's Day, the InnovaSpace team welcome news about the work of Dr Lucia Hartmann & Jasmin Mittag, with a new concept for the shape of future space travel and a desire to promote equality - an ethos we fully support!
The "Vulva Spaceship"
The first spacecraft in a V-shape is not only a symbol for more diversity in space, but also state-of-the-art and thus more sustainable. The “Vulva Spaceship” designed by “WBF Aeronautics” represents inclusivity, varying from the traditional shapes. Thus, the project adds another dimension to the representation of humanity in space and is communicating to the world that anyone has a place in the universe, regardless of physical characteristics.
Dr. Lucia Hartmann, Head of “WBF Aeronautics” and inventor of the “Vulva Spaceship” reports from her research: “The spaceship’s shape is surprisingly aerodynamic, creating way less drag when the vehicle punches through the Earth’s atmosphere. Due to this optimized V-shape, it guarantees maximum fuel efficiency with an exterior made of reinforced carbon which enables it to withstand the most extreme temperatures.” “WBF Aeronautics” wants to inspire space travel to be open to modern forms and to realise equal opportunities across the universe.
The Project "WBF Aeronautics"
“WBF Aeronautics” is a collaboration between Dr. Lucia Hartmann and her team and “Wer braucht Feminismus?” (WBF). Dr. Lucia Hartmann started her research work about spaceships and discovered that a spaceship varying from traditional shapes, would be more aerodynamic and create less drag, thus being more sustainable.
She reached out to us for the purpose of a collaboration and for us to do the media work as there is much more to it than just the scientific aspect. On the one hand, the topic is sensitive, but on the other hand, it also holds great opportunities. The symbol of a Spaceship in a V-shape represents more diversity in space. The project adds another dimension to the representation of humanity in space.
We believe that equality even has a place in space. It’s time for new symbols in the universe.

How can you transform the light of a star into music?
To turn the data into sound I used a sonification technique that was developed by Cristian Droppelmann & Ronald Mennickent, in 2018. Rather than transforming the data as carried out by the Fourier Transform and XSonify programs, the Droppelmann and Mennickent formula translates the data into musical notes by calculating the normalized magnitude from the actual magnitude of the star, and the normalized time from the Julian dates of the observation.
This can be done using MS Excel because the formula is simple and very easy to code. These normalized values have equivalent musical notes and musical rhythm, respectively, based on a table that they also created. Once translated into musical notes and rhythm, a digital audio workstation (DAW) is used to generate the audio.
This audio of the light curve can then be interpreted into a musical piece. Therefore, using this method, we can generate two audios: one is the actual audio of the light curve where there is a corresponding 1:1 ratio of magnitude to musical note, and the other is a 1:1 ratio of Julian dates to musical rhythm. Most of the time, although these musical notes follow a specific key signature and family chords, there are some notes that deviate, meaning, it seems to be out of tune. That is why we also arrange it into a beautiful musical piece.
The observed star – Delta Cephei, part of the constellation Cepheus
The star used for the audio is called Delta Cephei (abbreviated to Del Cep), located approximately 887 light-years away. It is a Type II Cepheid – a variable star type with a period of pulsation between 1 and 50 days. Delta Cephei itself has a period of pulsation of around 5 days, with a visual magnitude that changes within the range of 3.5 to 4.4. It is one of the stars in the Cepheus constellation, as seen in the constellation image below.
The Stellar Music
You can check out my stellar music by listening to the two audio files below:
1) Del Cep 2448606.58 to 2448636 - the actual audio of the light curve - not arranged and follows the 1:1 ratio
2) The Joy of Cephei - the arranged audio - this is the musical piece, arranged, and some notes were manipulated for aesthetic purposes.
Just remember - the sound that you hear is not from the interior of the star, rather, it is the sound that the light curve creates using the Droppelmann and Mennickent 2018 equations.
I hope you enjoy the stellar music…

Introduction from Eija Salmi, Secretary General, Cumulus Assoc. & Thais Russomano, CEO, InnovaSpace:
During the 21st century outer space has become a topic for discussion by passionate people in design universities worldwide. Some institutions have piloted initiatives and have ongoing activities in the art, design and media curriculum focused on space, considering how design can contribute to overcoming the challenges humanity will encounter when exploring this new frontier. We know for certain that living off-Earth will bring multiple challenges that require innovative solutions if we are to inhabit another planet. The field of design will be an essential element in facilitating space life, just as it is present everywhere in our lives here on Earth, whether on its own or collaboratively with other disciplines, such as medicine, engineering etc. Design education and research plays a massive role not only for the design profession, but also for business, industry and other institutional stakeholders in the space era to ensure a good, healthy and secure space future.
The aim of this blog today, written by Dr Dolly Daou, is to share knowledge and inspire all of us to rise to the challenges of humanity’s tomorrow in outer space – inspired by design. This is the first in a series!
Enjoy and please do share on your social media!
On Planet Earth, we have been accustomed to living our lives conditioned by daily habits; we eat, sleep, cook, work, walk, build, interact according to our environments, grounded by gravity. Culturally, we differ in customs, in habits, we eat different food, we live differently, we speak different languages, however what unifies us is the relationship between our physiology and our topography. This relationship is the result of the universal gravity system and the evolution of beings and their environment on Planet Earth, the Blue Planet. The colour blue refers to the interaction of solar rays with the gases of Earth's atmosphere. Similarly, Planet Mars is known as the Red Planet in reference to the mass of red soil that covers its surface. The colour coding of both planets reflects the relationship between our biological existence and our environmental characteristics, which influence our daily habits and our survival traits on these planets.
