A strange FM signal from one of the moons of Jupiter was discovered



NASA recently extended the life of two planetary discovery missions, including the Juno mission to Jupiter. Today, Juno has detected FM signals from Ganymede, one of the gas giants.

This discovery is not a sign of extraterrestrial life, but it is still fascinating because this is the first time it has been discovered from a celestial satellite.

NASA’s ambassador to Utah, Patrick Wiggins, said in a comment on Fox 8 Cleveland: “This is not ET.” “It’s more of a natural function. ”

“Creativity” in JUPITER’s colors?NASA’s JUNO spacecraft captured images that shocked the Internet

The spacecraft was launched into space in 2011, when it passed through the polar regions of Jupiter at a speed of 111,847 mph through a wireless power source called “full radio transmission” or Wi-Fi for short. It only saw five seconds of radio transmission, but there was enough time to confirm the source of the signal.

According to NASA, the frequency of decimal radio waves is between 10 and 40 MHz, but never exceeds 40 MHz. The space agency added: “Electrons circling in Jupiter’s magnetic field are believed to be 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 occurred from Ganymede.

These findings were recently published in the scientific journal Geophysical Research Letters.

It is worth noting that this is not the first time scientists have discovered a strange phenomenon on Ganymede. In 2018, due to the Galileo probe spacecraft, researchers observed “extraordinary” electromagnetic waves, also known as “chorus waves.”

Jupiter’s moon Ganymede has always attracted many astronomers because it is the largest moon on the planet. In 2015, NASA’s Hubble Space Telescope found evidence that Europa has an underground ocean.

Researchers say the ocean on the Jupiter moon “may be survivable”

Juno has made many discoveries on Jupiter, including capturing amazing, never-seen images, and the “snow-white” elliptical storm.

The Juno mission was launched in 2011 and was originally scheduled to cease operations in July 2021, but will now continue until September 2025 or the end of its service life, whichever comes first. Juno will not only continue to observe the gas giant, but will also observe the rings and moons of the planets, including the “close pass” of Ganimede, Europa and Io.

Researchers roughly say that Europa is the sixth largest moon in the solar system and the home of the “inhabitable” ocean.

In August 2019, the National Aeronautics and Space Administration (NASA) confirmed that it would send a mission to Europa to further explore the celestial body.
