Today’s News – Washington – Al-Arab Today
NASA recently extended the lifespan of two planetary exploration missions, including the Juno mission to Jupiter. And now Juno has detected an FM signal emanating from one of the gas giant Ganymede’s moons. This discovery is not an indication of the existence of extraterrestrial life, but it is nonetheless striking, given that it is the first time that such signals have been detected from a celestial moon. Launched in 2011, it was traversing the polar region of Jupiter at 111,847 miles per hour when it passed through a radio source, known as “decimal radio broadcast” or simply “Wi-Fi.” The vehicle saw the radio broadcast for only five seconds, but it was enough to confirm the source.
According to NASA, decimal radio waves have frequencies between 10 and 40 MHz, but no more than 40 MHz. The space agency added, “It is believed that electrons rising in Jupiter’s magnetic field are the cause of the radio noise we hear.” Scientists have known about radio waves on Jupiter since the mid-1950s, but this is the first time this phenomenon has emerged from Ganymede’s Moon.The results were recently published in the scientific journal Geophysical Research Letters, and it is not the first time that scientists discover strange events in Ganymede. In 2018, researchers observed “unusual” electromagnetic waves, called “chorus waves”, thanks to the Galileo Probe spacecraft.
Jupiter’s moon, Ganymede, has long dazzled astronomers because it is the largest moon on the planet. And in 2015, NASA’s Hubble Space Telescope discovered evidence of an underground ocean in Ganymede. Juno made a number of discoveries on Jupiter, including capturing unprecedented awe-inspiring images and an elliptical storm. The Juno mission began in 2015. The year 2011 was slated to cease operations in July 2021, but will now run until September 2025 or end of life, whichever comes first. Juno will not only continue to monitor the gas giant, but also to observe the rings and moons of the planet, including the “near flyby”. The moons Ganymede, Europe and Io.
