Scientists just witnessed Titan’s astonishing surface for the first time

The largest moon of Saturn is an unique habitat in our Solar System. It appears to be a world different from our own, with its methane-filled lakes, freezing volcanoes, and underground tunnels.

However, Titan’s first geomorphological map demonstrates that, while its landscape is spectacular and diverse, these elements actually make it surprisingly similar to Earth.

Scientists Devise Laser To Pick Up Alien Signals; Could This Be Key to Discovering Extraterrestrial Life?

Scientists have come up with laser technology that is capable of picking up alien signals from worlds that are far away. According to the Daily Star, the machine that is miniaturized was tailored to fit the specialized space missions of NASA. Such a device has the potential to revolutionize the long-standing search for extraterrestrial intelligence.
