High-tech Japan uses AI in song to welcome pope

Few aspects of life escape the touch of high tech in cutting-edge Japan, including an official song written to welcome Pope Francis when he visits Japan from Saturday. Written by Jun Inoue, the song, "Protect all Life - The Signs of the Times", is based on the theme of the pope's Japan visit and was partly composed using an artificial intelligence (AI)-powered programme Inoue created that can write a piece of music in a few seconds.

'Possibility of life': scientists map Saturn's exotic moon Titan

Scientists on Monday unveiled the first global geological map of Saturn's moon Titan including vast plains and dunes of frozen organic material and lakes of liquid methane, illuminating an exotic world considered a strong candidate in the search for life beyond Earth. The map was based on radar, infrared and other data collected by NASA's Cassini spacecraft, which studied Saturn and its moons from 2004 to 2017. Titan, with a diameter of 3,200 miles (5,150 km), is the solar system's second-biggest moon behind Jupiter's Ganymede. It is larger than the planet Mercury.

Spacecom's Amos-17 satellite completes test, reaches final orbit

Israel's Space Communications said on Monday its Amos-17 communication satellite, which was launched into space in August, has completed its in-orbit testing and reached its final position. Spacecom has suffered some major setbacks in recent years, including the loss of a satellite in 2016 when a SpaceX rocket exploded, and its shares were trading up 9% in Tel Aviv on Monday's news.

Japan space probe on its way back after asteroid mission

A Japanese space probe is heading home from an asteroid 250 million km (155 million miles) from Earth after collecting sub-surface samples that could help scientists seeking the origins of life, Japan's space agency said on Monday. Asteroids are believed to have formed at the dawn of the solar system and scientists say the asteroid, called Ryugu, may contain organic matter that may have contributed to life on Earth.
