A new study conducted by a team of researchers analyzed twenty years of information about the dynamic motion of the atmosphere of the Sun from the European Space Agency (ESA) and NASA’s Solar and Heliospheric Observatory (SOHO). This helped the researchers in listening to the loops, eruptions, and other activities of the Sun.
According to this study, the sun generates a pulsing, low “heartbeat.” Listening to these sounds of the Sun offers the scientists a distinct way of watching and analyzing the Earth’s sun as well as the other stars present in our Universe.
Alex Young, the Associate Director for Science in the Heliophysics Science Division at NASA’s Goddard Space Flight Center, told in the statement, “Waves are traveling and bouncing around inside the sun, and if your eyes were sensitive enough, they could actually see this.”
The use of solar observatory for measuring the vibrations of the sun revealed the things that are actually going on within and this can be of much help to the scientists involved in the study of solar flares and the “coronal mass ejections” inside the Sun.
Young explained, “We don’t have straightforward ways to look inside the sun. We don’t have a microscope to zoom inside the sun, so using a star or the sun’s vibrations allows us to see inside of it.”
The Stanford Experimental Physics Lab transformed information from the SOHO to a “song.” The researchers analyzed the natural vibrations of the sun that give rise to the “heartbeat” and hum.
Researcher Alexander Kosovichev at the Stanford University processed forty days of information from SOHO’s Michelson Doppler Imager (MDI) for developing an audio clip of the “heartbeat” of the sun. While organizing the vibrations, Kosovichev eliminated the effects of the movement of the spacecraft, chose cleaner sound waves, which would be transparent and easy for hearing and sped up the information by the factor of forty-two thousand for bringing it to the hearing range of human beings.
