The Voyager 1 spacecraft outside the solar system stopped sending useful data back to Earth
The Voyager 1 space probe is the farthest man-made object in space. It was sent in 1977 with a golden record on board that contained various sounds of our home planet: greetings in different languages, dogs barking and the sounds of two people kissing, to name just a few examples. The idea behind this recording was that Voyager 1 might one day become an emissary of alien life—a sonic time capsule of the creatures of Earth. Since its launch, it has also managed to complete missions to Jupiter and Saturn. In 2012, he crossed interstellar space.
Saturn’s moons: organic compounds discovered on Enceladus; Mimas has a subglacial ocean
The Cassini probe delivered new information about the moons of Saturn. In the subglacial ocean of Enceladus, Saturn’s moon, many organic compounds involved in the synthesis of proteins and DNA were discovered. This is very similar to the “primordial soup” that existed on Earth billions of years ago. There may be life on a distant, icy world at the edge of the solar system. Saturn has 146 moons, the most in the solar system. The largest one, Titan, has long been considered the most interesting. The Huygens lander was sent to it as part of the Cassini mission in 2005. Behind the dense atmosphere, the probe saw a lifeless, cold world, shrouded in smog, with seas and lakes of methane. Some evidence suggests that there is an ocean below the surface.
