Check out today’s eclectic coverage of programs broadcast and streamed on the (occasionally “far side”) state of affairs on our pale blue dot, signaling our existence to possible exo-civilizations.
“FM signals and those of broadcast television travel out to space at the speed of light. Any eavesdropping alien civilization will know all about our TV programs (probably a bad thing), will hear all our FM music (probably a good thing), and know nothing of the politics of AM talk-show hosts (probably a safe thing).” –Neil deGrasse Tyson, Death By Black Hole
“The history of life on Earth provides us with a wealth of information about how biology can overcome the challenges of environments we would think of as hostile,” said astronomer Jack O’Malley-James with the Carl Sagan Institute where his interests lie firmly at the intersection between astronomy, biology and geophysics, which is a perfect place from which to explore questions about how life would influence exoplanet atmospheres, climates and detectable biosignatures.
“We are, yet again, blown away by Enceladus. Previously we’d only identified the simplest organic molecules containing a few carbon atoms, but even that was very intriguing,” said Southwest Research Institute’s Christopher Glein, a space scientist specializing in extraterrestrial chemical oceanography in June of 2018.
A NASA study based on new data from the Curiosity Mission rover reveals asteroid impacts on ancient Mars could have produced key ingredients for life if the Martian atmosphere was rich in hydrogen.
In recent months several leading astrophysicists from NASA to Harvard have suggested aliens are not science fiction: that advanced and ancient technological civilizations may exist but be beyond our comprehension or ability to detect. Silvano P. Colombano at NASA’s Ames Research Center proposes that we may have missed signals when it comes to looking for UFOs.
Two mind-boggling conjectures about the existence of advanced alien civilizations have been made by Harvard’s chief astronomer and the director of Columbia University’s Astrobiology Center.
