Global Exoplanet Oceans –“May Support More Active, Abundant Life than Earth”

Exoplanet Ocean

 

“NASA’s search for life in the Universe is focused on so-called Habitable Zone planets, which are worlds that have the potential for liquid water oceans,” says Stephanie Olson at the University of Chicago. “But not all oceans are equally hospitable–and some oceans will be better places to live than others due to their global circulation patterns”.

“Two More” –Earth-like Planets Found in Our Milky Way Backyard

Red Dwarf Planets

 

“We have been observing this star for three years to look for periodic variations in its velocity,” explains Mathias Zechmeister, a researcher at the University of Göttingen. The observations showed that two planets are orbiting it, both of them similar to the planets in the inner part of the Solar System. They are just a little bigger than the Earth and are situated in the “inhabitable zone” where water can exist as a liquid.

“We May Have Company” –Cambridge U Exoplanet Team Predicts Alien Life

 

ESO Observatories

 

Are Homo sapiens a one-off, genetic accident? Scientists have identified a group of planets outside our solar system where the same chemical conditions that may have led to life on Earth exist in what they call the Abiogenesis Zone. It’s also possible that if there is extraterrestrial life, that it has, or will, develop in a totally different way than it did on Earth.

“Alien Worlds Buried in Kepler Data” –New Algorithm Yields 18 Earth-sized Exoplanets

 

Kepler Spacecraft

 

“Our new algorithm helps to draw a more realistic picture of the exoplanet population in space,” says Michael Hippke of Germany’s Sonneberg Observatory about 18 previously undetected planets buried in data from the Kepler Space Telescope, one of which orbits its red dwarf star within the habitable zone. “This method constitutes a significant step forward, especially in the search for Earth-like planets.”

“Kepler’s Last Light” –First & Final Images of the Iconic Spacecraft’s Field of View

 

Kepler's Last Light

 

You can’t help but wonder what unknown worlds and, perhaps, advanced civilizations might be awaiting discovery within the final record of the Kepler spacecraft’s full field of view before the depletion of fuel permanently ended its work. NASA retired the iconic spacecraft on Oct. 30, 2018, to a safe orbit. The Kepler field of view represents 1/400 of the Milky Way Galaxy and its 100 billion stars.
