A new way of forming planets
In the last 25 years, scientists have discovered over 4000 planets beyond the borders of our solar system. From relatively small rock and water worlds to blisteringly hot gas giants, the planets display a remarkable variety. This variety is not unexpected. The sophisticated computer models, with which scientists study the formation of planets, also spawn very different planets. What the models…
The 1st sign of intelligent life beyond Earth?

A robot submarine could explore Titan’s deepest sea
A new study of data from NASA’s bountiful Cassini mission shows that Titan’s largest methane sea, Kraken Mare, is at least 1,000 feet – 300 meters – deep near its center. That’s plenty of room for a future robotic submarine to explore. Source: https://earthsky.org/space/titans-largest-sea-kraken-mare-is-1000-feet-deep…
