NASA has published an amazing video titled “Sounds of Saturn: Hear Radio Emissions of the Planet and Its Moon Enceladus”. The analyze of the data from the Cassini Spacecraft’s Grand Finale orbits showed a surprisingly powerful interaction of plasma waves moving from Saturn to its icy moon Enceladus. Researchers converted the recording of plasma waves into a “whooshing” audio file that we can hear, in the same way a radio translates electromagnetic waves into music.
Much like air or water, plasma (the fourth state of matter) generates waves to carry energy. The recording was captured by the Radio Plasma Wave Science (RPWS) instrument on September 2, 2017, two weeks before Cassini was deliberately plunged into the atmosphere of Saturn.

To put things into a perspective, here are the moons of our solar system (including our moon) and their sizes compared to Earth.

According to a new study, microbes like those found in Earth’s deep ocean could potentially thrive in the underground ocean of Saturn’s icy moon Enceladus. Both molecular hydrogen (H2) and methane (CH4) already have been detected in the plume. Researchers have shown that Methanothermococcus okinawensis, a methanogenic archaeon first isolated from a deep-sea hydrothermal vent on the western Pacific Ocean, can produce methane under conditions known to exist on Enceladus.

NASA (The National Aeronautics and Space Administration) has published a video that contains highlights of important events and the space agency’s achievements over the year 2017.

In September 2017, Elon Musk, the founder and CEO of SpaceX has revealed a new plan to colonize Moon and Mars with giant reusable spaceships. They are ambitiously planning to send the first humans to Mars as early as 2024 to build the foundations for the first Martian city. But is Mars really the best place for humans to settle? Some scientists, like Amanda HendrixNotes 1, the American planetary scientist, thinks it’s not, and we should be looking somewhere else and colonize Titan, Saturn’s largest moon, instead.

Earth is actually a fragile and isolated rock, a “blue marble” in a vast, cold and hostile space. But only after seeing our planet from space we truly understood that. Seeing the Earth first time from a distance was a powerful experience which has changed the way we see our planet. Here are the top 10 most iconic photos of Earth from space.

Launched on October 15, 1997, NASA’s Cassini spacecraft Notes 1 went into orbit around Saturn on July 1, 2004. Since then, it has taken thousands of photos of Saturn, the second-largest planet in the Solar System, its prominent rings, and moons. And on September 15, 2017, Cassini plunged into Saturn’s atmosphere and disintegrated. Here are the 20 most beautiful photos that the spacecraft has sent back to Earth during its 13-year voyage around the gas giant.
Cassini was destroyed by diving into the Saturn’s atmosphere on September 15, 2017. This method of disposal was planned to avoid potential biological contamination of Saturn’s moons, since Titan, Enceladus, and other icy moons of Saturn may harbor oceans and alien life.
