Extraterrestrial Water: Hidden Oceans in Our Solar System

Posted by in category: alien life

While the scientific debate about the origin of water on our planet remains open, the truth is that relative to its size, Earth is more like a desert compared to other celestial bodies in our cosmic neighbourhood. Estimates vary, but there could be as much as 50 times more liquid water in the solar system than is found on Earth—an astonishing revelation that would have sounded absurd just a few decades ago. And scientists are eager to send spacecraft to this extraterrestrial water in the hope of discovering conditions suitable for life.

Apart from Earth, the inner solar system—containing the four planets closest to the Sun—is largely devoid of liquid water. On Mercury and Venus liquid water simply boils away, while on Mars any liquid water would quickly freeze or evaporate due to the low atmospheric pressure and temperature. Although there is some intriguing evidence that liquid water may exist beneath the Martian southern polar ice cap, the amounts would be very small compared to those found on Earth.

Paradoxically, to find to find an unexpected abundance of liquid water, we must venture into the frigid depths of the outer solar system, far from the warmth of the Sun. There, deep beneath the frozen surfaces of moons orbiting the gas giants Jupiter, Saturn, Uranus and Neptune, scientists have found strong evidence of vast oceans. But how can water remain liquid in such an extremely cold environment, where the Sun is only a faint glow in the sky and the warmest surface temperatures are always well below zero?

Aliens could exist on planets scientists least expected after shock discovery

Posted by in categories: alien life, futurism

Scientists could have been looking for extraterrestrial life in the wrong place all along, after it was revealed that unexpected types of star systems could be the key to potential discoveries in the future.

New research suggests that many of the things we thought about the habitable nature of certain planets could be proven wrong.

Do you know why humanity still doesn’t have colonies on the Moon or Mars? Because the big companies that might’ve invested their money in building the said colonies are not sure when they’ll get their investments back and start making a solid profit. Well, at least that’s one of the reasons.

NASA’s snake-like robot concept could search for life on Saturn’s moon

Posted by in categories: alien life, robotics/AI

This one-of-a-kind robot is an exobiology extant life surveyor (EELS) developed by NASA’s Jet Propulsion Laboratory.

It is time to move over the traditional wheeled or legged robots. NASA has developed a robotic concept that sounds straight out of a science-fiction and has the potential to take space exploration to the next level.

The US space agency has been working on sending a snake-like robot to explore and search for extraterrestrial life forms in the solar system. This robot is an exobiology extant life surveyor (EELS) developed by NASA’s Jet Propulsion Laboratory.

(podcast) A conversation with Frank White

Posted by in categories: alien life, information science

Whether this “complements or contradicts existing religious value systems depends largely on the interpretation of those systems by the people who have adopted them,” said Frank. “However, my interviews with astronauts of faith suggest that their religious perspective was strengthened, rather than being weakened.”

Frank notes that his cosmology has parallels with Yuval Harari ’s “dataism,” described by Harari as the “most interesting emerging religion.” Dataism, as defined by Harari, “says that the universe consists of data flows, and the value of any phenomenon or entity is determined by its contribution to data processing.” This may sound kind of cold and metallic, but if life is an algorithm and self-awareness is data processing the parallels with Frank’s ideas are evident.
