EXTRATERRESTRIAL LIFE

A new paper has come out discussing how the Fermi Paradox might be explained by the rigors of traveling space for interstellar colonization, causing settlements to be rare and and possibly not long-lived. We'll look at this model for spreading humanity out across the galaxy and see what insights or flaws it might have.

If we want to discover alien life out there in the universe, we first need to figure out where to look—and what we're even looking for. Will it be biological like us? Could it be artificial, or take some other form we haven't yet considered? And how do we find something so fundamentally different from ourselves? In this program, scientists devise plans for searching for beings beyond Earth while they grapple with the very definition of life.

Some of these factors include: Special place in the Milky Way It turns out our position in the Milky way might be beneficial as the low star density prevents other stars from messing up our orbits. The right type of star. Our sun is a G2 main sequence star that remains stable for a very long time. Rocky planet in the Goldilocks zone Earth is just the right distance from the sun to form liquid water. Magnetic Shield We're the only rocky planet with a magnetic shield protecting us from solar radiation. Jupiter Jupiter and the outer gas giants protect us from asteroid and comet impacts, and this might be rare in the universe. Tectonic activity We're the only planet with tectonic plates constantly rebuilding the crust.

Even on arrival terraforming those barren planets would take just as long. Two options for overcoming the immensity of space and time are the Seed Ship and the Data Ship, automated vessels able to colonize the worlds for us. We will examine those today, their advantages, limitations, and misconceptions, and variations of them we might use to seed the stars.

For more than four decades, astronomers have been searching for technosignatures: signals coming from distant technological civilizations. The first SETI searches began in the 1960s by searching for extraterrestrial radio waves and have more recently expanded to include optical (visible) signals, such as powerful laser pulses. We know that, like technological progress, the search is also accelerating, evolving with the development of new antenna arrays and new networks of telescopes which will soon be capable listening to the entire sky, everywhere, and all the time. It is impossible to know when we will get our first contact and what this message will say, but we know that this discovery will have an ethical and political impact on our world. And then what will happen next? Will the detection of ET be dangerous or beneficial for humankind? Will it change everything, including our place in the universe or will we simply continue our life knowing that ‘We are not alone’? To discuss these points, we invited four SETI researchers: Julia DeMarines, Astrobiologist and Science Communicator at the UC Berkeley SETI Research Center, Doug Vakoch, President of METI, Eliot Gillum, director of LASER SETI and Seth Shostak, Senior Astronomer at the SETI Institute.

For the past half-century, humanity has been listening for alien radio transmissions but so far we appear to be the only ones broadcasting into the void. Astrobiologists now seek to narrow down the search by looking for other technological and biological signatures. In this video, I explore some of the methods by which they hope to do so and why the great silence of the universe is such a mystery.

Another episode of Night Sky News for this month - the first half what you can see in the sky this next month and the second half a recap of the space news of the last month. Tune in for how to catch Comet Wirtanen and the Geminids Meteor Shower in December. In this episode I chat about the retirement of the Kepler Space Telescope, the discovery of Antlia 2, a new dwarf galaxy around the Milky Way, and the discovery of a super-Earth exoplanet around Barnard's star. I also explain why astronomers have claimed that the interstellar object 'Oumuamua *might* be an alien space probe, and discuss the controversial news about the new Thirty Meter Telescope.

(2018) https://go.nature.com/2A9FncQ Last year a visitor came to our inner solar system. To us it looked like a faint spot of light, moving quickly relative to the fixed stars. We’d seen similar things countless times before – lonely rocks, remnants from the formation of our solar system, drifting on their endless orbits around the sun and faintly glimmering with its reflected light. Nothing unusual about such asteroids and comets, but what made this object special was its trajectory. It was not in orbit around the Sun at all. Rather, it appeared to have fallen in from interstellar space, and was on its way back out again. The object is 1I/2017 U1, better known as ‘Oumuamua. It’s the first chunk of interstellar space debris we’ve ever spotted passing through our solar system. It caused a justifiable stir at the time. Hell, WE even did an episode on it.

In this video, we discuss the space object Oumuamua and the odd traits that make scientists question its origin. Oumuamua was discovered in October of 2017 and was quickly denoted as an interstellar object, due to its have speeds in our solar system. Over the course of a few months, astronomers all over the world were able to determine the approximate size, shape, and composition of this object, however, it didn't match what scientists had previously expected an interstellar object to be like. Over time, the object was also varying in its trajectory slightly, which brought up many more questions regarding the origin of these disturbances and what could be happening. Recently, scientists at Harvard suggest that this could be a solar sail, created by some intelligent alien species, trying to understand planet Earth. In this video we walk through the different known facts about Oumuamnu, and why it may or may not be an alien spaceship. Thanks for watching! And consider subscribing if you enjoyed this video!

According to a report by Business Insider, scientists at Harvard have raised the possibility that a mysterious cigar-shaped interstellar object, the first of its kind in our solar system, could be a probe intentionally sent toward Earth from an alien civilization. Named, "Oumuamua," which means "a messenger from afar, arriving first," the object was first spotted in October of 2017 by a telescope in Hawaii. The metal-rich object, reportedly moving remarkably fast but not circling our sun, was about 750 feet by 115 feet and reddish in color. https://www.businessinsider.com/harvard-scientists-interstellar-oumuamua-object-alien-probe-2018-11 http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

A recent MIT study found that existing technology could be used as a “porch light” of sorts to let aliens know that we’re here.

Astrophysicists say 'Oumuamua might be an alien object.

MeerKAT combines 64 individual dishes as a single instrument to be used by teams from across the globe in pursuit of a range of science goals. Listen’s MeerKAT search for signs of extraterrestrial technology will operate 24 hours a day, seven days a week, operating in parallel with the other surveys. Listen's survey will examine a million individual stars in the quietest part of the radio spectrum, a factor of 1000 more targets than any previous search.

The universe is incredibly old, astoundingly vast and populated by trillions of planets -- so where are all the aliens? Astronomer Stephen Webb has an explanation: we're alone in the universe. In a mind-expanding talk, he spells out the remarkable barriers a planet would need to clear in order to host an extraterrestrial civilization -- and makes a case for the beauty of our potential cosmic loneliness. "The silence of the universe is shouting, 'We're the creatures who got lucky,'" Webb says.

While our search is still in its infancy, we haven't yet found any obvious signs of intelligent life in our galaxy. One reason could be that any advanced civilization out there may not have made it past a stage in its development where climate change became an issue. As technologies advance and use more resources on a planet, care needs to be taken that the planet's carrying capacity is not overwhelmed. This could lead to the demise of a civilization and prevent it from expanding to the stars. Our guests for this hangout have done some modelling on the possible consequences of advancing technology and its effects on the host planet.
