The researchers made a bizarre discovery that amazed them. It is the first time that a signal of this type is captured, coming from the direction of the satellite of the planet Jupiter.
NASA has recently extended the duration of two of its space missions to discover new planets. These include Juno’s mission to Jupiter. It has now been revealed that Juno has discovered an FM signal coming from one of the gas giant’s natural satellites. This is called Ganymede.
This information is not proof of the existence of extraterrestrial life, but it is fascinating. However, it is the first time it has been discovered coming from the celestial satellite. “It’s not ET. It’s more of a natural function,” said Patrick Wiggins, one of NASA’s ambassadors in Utah, USA.
The spacecraft, which was launched in 2011, was in the polar region of Jupiter, moving at a speed of 180,000 km / h, when it identified the radio source. This is known as “decimetric radio broadcast” or simply Wi-Fi. He received the radio broadcast for only five seconds, but it was enough to confirm where he came from.
According to NASA, decimetric radio waves have frequencies between 10 and 40 MHz, but never above 40 MHz. “It is believed that the electrons spiraling in Jupiter’s magnetic field are the cause of the radio noise we hear,” the space agency added, informs Fox News.
Scientists have known about Jupiter’s radio waves since the mid-1950s, but this is the first time the phenomenon has ever been observed with Ganymede as its source. The findings were recently published in the scientific journal Geophysical Research Letters.
Although this information is remarkable, it is not the first time that scientists have discovered strange events on Ganymede. In 2018, researchers observed “extraordinary” electromagnetic waves, also known as “chorus waves”, due to the Galileo Probe spacecraft.
Jupiter’s moon, Ganymede, has long fascinated astronomers because it is the largest natural satellite on the planet. In 2015, NASA’s Hubble Space Telescope discovered evidence that Ganymede has an underground ocean.
