our planet, earth, makes many sounds that we cannot hear Like ultra-low frequency waves that create a raucous opera depicting the dramatic relationship between Earth and the Sun. Now, Thanks to a new NASA-funded citizen science project called HARPallowing us to accurately hear the melody of the universe like never before.
In this ‘Audited Heliophysics‘ You will be able to hear the hiss and crackle depicting a journey through the cosmic vibrations singing the song of the Earth and the Sun. The connection between the Sun and the Earth is vital to life as we know it. On the one hand, solar energy is essential for the photosynthesis of plants, which in turn is the basis of the food chain and is also responsible for the Earth’s climate and the circulation of the oceans and atmosphere. What would your tune be like?
Contrary to popular belief, space is neither an empty nor a boring place, rather it is full of activity, with The vast majority of matter in the universe (99.999%) in the form of a mysterious plasma Which, in turn, is composed of charged particles emanating from energetic sources such as the Sun, whose motion creates waves similar to sound waves traveling through space. However, our human ear is unable to perceive these types of waves as they are far below our hearing range, but technology can help us with this problem. heard at about 1 Hz and lower (Hence they are known as very low frequency waves).
Ultralow-frequency (ULF) waves are in the 0.1 to 10 hertz (Hz) range, so they are at the very bottom of the electromagnetic spectrum, just above ELF waves (extremely low frequencies).
naturally, mainly as a result of interactions between Earth’s magnetic field and charged particles that flow in the solar wind. Thus, the magnetic shield that surrounds Earth, which protects us from the sun’s harmful rays, is filled with these waves as the plasma interacts with it. These ultra-low frequency waves are also generated by the electrical activity associated with thunderstorms in Earth’s upper atmosphere.
harp instrument It is designed to allow citizens to participate in space science research through a web interface that provides audio data captured by satellites. And thus can identify wave patterns interesting to our human ear and outperform even advanced computer algorithms. With it, citizen scientists can join the journey of sound space exploration to understand the cosmic vibrations that help sing the song of the Sun and Earth.
“The process of identifying new features through deep listening is like a treasure hunt,” he says. Robert Alexander, HARP team member. “I’m excited for people around the world to try this experience through the HARP Project.”
Preliminary investigations have begun to reveal unexpected features, such as what the team calls a “reverse harp”: frequencies change opposite to what scientists expected.
“What excites me most about the HARP project is the potential for citizen scientists to make new discoveries in heliopsis research through audio analysis,” said Michael Hartinger, heliophysics at the Colorado Institute for Space Sciences and a member of the project. continues the principal investigator. Funded by NASA. “We need your help understanding the complex patterns in the near-Earth space environment.”
In the same way, the HARP instrument can provide us with data on the phenomenon that other NASA citizen scientists have found, such as waveforms aurorae examined through the Aurorasaurus project or sounds heard by radio amateurs participating in the HamSCI project.
