Does anyone believe extraterrestrials have visited Earth? I am super curious to see what the members of this group believe!
A habitable zone is an area just the right distance from a star so water can exist on a planet’s surface and the conditions are neither too hot nor too cold for life.
Scientists believe they’ve discovered a cache of gemstones on the surface of Mars.
No, we’re not talking about diamonds — according to a study published last month in the Journal of Geophysical Research: Planets by a team of Arizona State University and NASA-affiliated researchers, the Red Planet’s Gale Crater is teeming with opals.
Let’s get it out of the way: bling iced out with precious gems from another planet sounds like the coldest flex in the solar system. But there’s also scientific significance to the finding, which suggests that the area held vast reserves of water far more recently than we previously thought. That means the discovery could also force us to rewrite theories of ancient life on Mars.
Avi Loeb joins John Michael Godier to discuss his new initiative the Copernicus Space Corporation. ‘Copernicus’ is a privately held, novel type of space exploration company, headquartered in Massachusetts, which fosters ultra-long-range thinking and leverages disruptive technology for new human strategies in space. Avi also discusses the Galileo Project and its scientific search for UAP. Also discussed, can we detect gravity wave signals from alien civilizations?

Where are all the aliens?
Is there a solution to the fermi paradox?
Joining John Michael Godier is Dr. Stephen Webb, astronomer and author of ‘If the Universe Is Teeming with Aliens… WHERE IS EVERYBODY? Seventy Five Solutions to the Fermi Paradox and the Problem of Extraterrestrial Life’.

Scientists at the recently opened SETI Post-Detection Hub at the University of St Andrews in Scotland have a daunting task ahead of them: figure out what…

What is the Drake Equation? We are talking about The Odds of ALIEN LIFE.
Is there life out there in the Universe?
How are the chances to find Extraterrestrial life?
We don’t know the answers to a lot of questions, for example:
How many alien societies exist, and are detectable?
Even though we don’t know how to answer such a question, we can at least try to figure it out with a little help from our beloved…Math.
First, we have to have a pretty good idea about how the universe works, and of course about the star and planetary formation, as well as conditions for life as we know it. This means we have to study and collect a lot of data. Luckily for us, we – humans — aren’t so bad. Physics, astronomy, chemistry, biology and all-natural sciences offer us the hints for the mathematical set of parameters that will give us an equation to calculate the number of alien societies that exist and are detectable.
Second, one has to sit down and think about which parameters should appear in the equation, and which not.
Do you think it’s difficult? I think so.
But luckily for us, in 1961 scientists Drake came up with a famous equation, that estimated the number of transmitting societies in the Milky Way Galaxy…

Pity the poor astronomer. Biologists can hold examples of life in their hands. Geologists can fill specimen cabinets with rocks. Even physicists get to probe subatomic particles in laboratories built here on Earth. But across its millennia-long history, astronomy has always been a science of separation. No astronomer has stood on the shores of an alien exoplanet orbiting a distant star or viewed an interstellar nebula up close. Other than a few captured light waves crossing the great void, astronomers have never had intimate access to the environments that spur their passion.
Until recently, that is. At the turn of the 21st century, astrophysicists opened a new and unexpected era for themselves: large-scale laboratory experimentation. High-powered machines, in particular some very large lasers, have provided ways to re-create the cosmos, allowing scientists like myself to explore some of the universe’s most dramatic environments in contained, controlled settings. Researchers have learned to explode mini supernovas in their labs, reproduce environments around newborn stars, and even probe the hearts of massive and potentially habitable exoplanets.
How we got here is one of the great stories of science and synergy. The emergence of this new large-scale lab-based astrophysics was an unanticipated side effect of a much broader, more fraught, and now quite in-the-news scientific journey: the quest for nuclear fusion. As humanity has worked to capture the energy of the stars, we’ve also found a way to bring the stars down to Earth.
