Hydrogen found in plumes on Saturn’s moon Enceladus

Science Magazine explains the importance of finding hydrogen in the plumes of Enceladus. It is a sign of ongoing reactions on the floor of a probable subsurface alien sea and such chemistry provides energy for microbial life on Earth.  

NASA: Ingredients for Life at Saturn’s Moon Enceladus

The spacecraft Cassini is on its last legs, but that doesn’t hinder it from making one last effort, providing us with some very interesting data about Saturns moon Enceladus. The spacecraft discovered hydrogen in the plume of gas and icy particles spraying from Saturn’s moon Enceladus. The discovery means the small, icy moon — which …

Wendover Productions: How to Make First Contact

Are we alone? Are there aliens out there? If so, how do we find them? Once we find them, how do we contact them? And once we contact them, how do we actually communicate with them?  

PBS: Space Time | Have They Seen Us?

Are aliens watching Earth TV? We’d like to credit the SKA Organization for the image used in the thumbnail.  

PBS: | Space Time | Are We Alone? Galactic Civilization Challenge

The Drake Equation tells us the likelihood that there are other advanced technological civilizations waiting for us among the stars. In this episode of Space Time we challenge you to use the Drake Equation to help us determine how near or far these alien races may be. Everything we’ve learned about our universe tells us …

PBS: Space Time | Life on Europa?

The Hubble Telescope found more evidence of vast plumes of water bursting through the icy surface of Jupiter’s moon Europa. What does this tell us about the potential for life on Europa? New findings have increased the likelihood that there is a vast ocean lying under the surface of Europa. Jupiter’s moon is emerging as …

TED: 3 moons and a planet that could have alien life | James Green

Is there life beyond Earth in the solar system? NASA director of planetary science James Green says we don’t know yet, but that we’re “hot on the pursuit” and will answer that question in 10 years. It’s all about the ingredients needed for life: liquid water, energy and organic material. So when we look out …

SETI Institute: The Search for Life Beyond Earth and Science of the SETI Institute – Bill Diamond

The longest recorded case of hiccups lasted for 68 years … and was caused by a falling hog. While that level of severity is extremely uncommon, most of us are no stranger to an occasional case of the hiccups. But what causes these ‘hics’ in the first place? John Cameron takes us into the diaphragm …

TED Ed: Should we be looking for life elsewhere in the universe? – Aomawa Shields

As the number of “potentially habitable” planets that astronomers find continues to rise, we seem ever closer to answering the question, “Are we alone in the universe?” But should we be looking for life elsewhere? If we were to find life in one of these worlds, should we try to contact any beings who may …

SVAstronomyLectures: Finding a New Earth: Exoplanets and the Habitable Zone

Dr. Stephen Kane (San Francisco State University) Over 1500 new planetary systems have been discovered, many of which include planets quite different from those in our own Solar System. A key step towards finding “Earth 2.0” will be to identify rocky planets that occupy the “Habitable Zone” of their stars. Dr. Kane describes what the …

Silicon Valley Astronomy Lectures: Innumerable Globes Like This One: The Search for Life Beyond the Solar System

Dr. Tori Hoehler (NASA Ames Research Ctr.) Our Galaxy probably hosts billions of planetary systems. But how many of those globes are like the Earth and how can we determine whether life has taken hold there, too? In this talk, Dr. Hoehler discusses the science of searching for life beyond our immediate neighborhood, and how …
