Half of Sun-Like Stars in Galaxy Could Host a Habitable Planet

• A new study claims that the Milky Way galaxy could in fact be home to many other inhabitable planets just like ours, within the ‘habitable zone’ of its star – just the right orbital distance where water has the potential to be stable on a planet’s surface. There are around 200 billion G dwarf stars just like our sun, so the chances of some of these solar systems having a planet like Earth is conceivable.

• To illustrate how vast space is, 200 billion stars is only 7% of the Milky Way. Says the study’s co-author, Jeff Coughlin, “This is the first time that all of the pieces have been put together to provide a reliable measurement of the number of potentially habitable planets in the galaxy.” Coughlin is an exoplanet researcher at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California. “We’re one step closer on the long road to finding out if we’re alone in the cosmos.”

• Building upon NASA’s Kelper’s science studies conducted between 2009 and 2018, a 2020 team, led by Steve Bryson of NASA’s Ames Research Center in California, has worked hard to discover more than 2,800 exoplanets to date. Bryson and his crew have also examined the European Space Agency’s Gaia spacecraft’s stellar properties which maps out billions of Milky Way stars.

• With all that data, the researchers have been able to predict the occurrence rates of potentially habitable Earth-sized rocky planets along with a sun-like star of similar temperatures. And the chance of there being other life forms on planets like ours is becoming more and more likely.

[Editor’s Note]   What a waste to have these scientists spend their sad careers focused on deep state red herrings, just to give the public the impression that they are diligently looking for intelligent extraterrestrial life but cannot find any, when ETs currently reside throughout our solar system and extraterrestrial civilizations permeate the galaxy and the universe. They just don’t want us to know about it.

A new study suggests there are plenty more planets just like ours out there, suggesting we aren’t alone after all.

Having barely touched the tip of space exploration, we are still largely unaware of what is out there – let alone what’s beyond the power of any NASA probe, satellite, or telescope at our disposal.

However, recent research claims the Milky Way could in fact be home to many other inhabitable planets

just like ours, when it comes to exploring the sun-like stars that could have small planets within each’s so-called ‘habitable zone’. The breakthrough claims these zones are just the right orbital distance where water has the potential to be stable on a planet’s surface.

The findings give a glimmer of hope to that age old question of whether it’s just us in the universe; reminding us that there are around 200 billion G dwarfs, aka balls of burning gas just like our sun, so the chances of some of them lighting up planets just like Earth is conceivable, Space.com reports.

But, just to illustrate how vast space is, the figure of 200 billion is only 7% of the Milky Way, as co-author of the study, Jeff Coughlin, shared the significant news, saying, ‘This is the first time that all of the pieces have been put together to provide a reliable measurement of the number of potentially habitable planets in the galaxy.’

Coughlin, an exoplanet researcher at the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California, also said, ‘This is a key term of the Drake Equation, used to estimate the number of communicable civilizations.’

Jesuit Astronomer Says Extraterrestrial Communication Possible

Article by J-P Mauro                                August 28, 2020                                (aleteia.org)

• In a study paper published in the International Journal of Astrobiology, co-author Father Jose Funes, a Catholic priest and an expert in galaxies and extragalactic astronomy who holds the chair in Science, Religion and Education at the Catholic University of Cordoba, Argentina, theorizes that in a long-enough timeline, Earth could intercept messages from intelligent extraterrestrial civilizations.

• The researchers created a simulation to study “casually connected nodes,” ‘nodes’ being the term for unknown intergalactic civilizations. They then ran these thousands of nodes through the simulation to conclude that communication with an ET civilization is directly related to how many sophisticated civilizations exist in the Milky Way.

• As a result, the study suggests that the probability of Earth receiving intergalactic messages is low, overall. But the likelihood of such a discovery is greatly increased if the galaxy is “densely populated with long-standing civilizations.” The longer a civilization exists, the greater the chance that it will develop technology that could be used for intergalactic messaging.

• “[T]hough the odds are not very high, there is a chance to communicate with ET,” says Father Funes. “All this effort in studying probabilities and communicating with alien civilizations helps to understand better who we are. It is important to step out from our anthropomorphic and anthropocentric way of thinking to deal with a very profound diversity, the cosmic otherness.”

• The study team notes that we can increase our chances of interacting with extraterrestrial civilizations by enacting our own interstellar exploration, colonization, and settlement. They also suggested probes that could self-replicate as a means of exploring the furthest reaches of space.

[Editor’s Note]    Is the Catholic church getting people used to the notion that the galaxy could be “densely populated with long-standing civilizations”? Is this part of the long, drawn-out, drip drip drip of disclosure?

 

A Catholic priest has co-authored a study on intergalactic communications, which theorizes that, on a long enough timeline, it is possible that Earth could intercept messages from extraterrestrial civilizations.

The paper, published in the International Journal of Astrobiology, suggests that communication with an intelligent civilization is directly related to how many sophisticated civilizations exist in the Milky Way. The study came to this conclusion by creating a simulation that studied “casually connected nodes,” nodes being a term for unknown intergalactic civilizations.

The researchers ran these thousands of nodes through the simulation, which led them to suggest that the probability of Earth receiving intergalactic messages is overall low. They do note, however, that the likelihood of such a discovery is greatly increased if the galaxy is “densely populated with long-standing civilizations.” They suggest that the longer a civilization exists, the greater the chance that it will develop technology that could be used for intergalactic messaging.

NASA Says Milky Way Could Have ‘Ocean Worlds’ All Over

Article by Chris Ciaccia                          June 22, 2020                              (nypost.com)

• NASA researchers have published a study in the Publications of the Astronomical Society of the Pacific saying that more than a quarter of the 53 exoplanets outside our solar system may be “ocean worlds” having significant amounts of water.

• “Plumes of water erupt from Europa and Enceladus, so we can tell that these bodies have subsurface oceans beneath their ice shells and they have energy that drives the plumes, which are two requirements for life as we know it,” said the study’s lead author Lynnae Quick, a NASA planetary scientist. “So if we’re thinking about these places as being possibly habitable, maybe bigger versions of them in other planetary systems are habitable too.” As such, Europa and Enceladus, moons that orbit Jupiter and Saturn, respectively, are icy celestial bodies that could harbor extraterrestrial life.

• Quick and the other researchers looked at exoplanets similar in size to Earth, along with exoplanets’ density, orbit, temperature, mass and distance from their star to reach their conclusions. These “ocean worlds” could release more energy than even Enceladus and Europa.

• Although studies tend to focus on exoplanets like ours that have a global biosphere so abundant it’s changing the chemistry of the whole atmosphere, NASA Goddard astrophysicist and study co-author Aki Roberge says, “(Within our) solar system, icy moons with oceans, which are far from the heat of the Sun, still have shown that they have the features we think are required for life.”

• Future missions searching for exterritorial life within our solar system include the Europa Clipper mission set to launch as soon as 2023, which will explore the surface of Europa. “If we find chemical signatures of life, we can try to look for similar signs at interstellar distances,” Quick added.

• As of June 2020. More then 4,000 exoplanets have been identified, approximately 50 of which were believed to be potentially habitable. A study published earlier this month suggested that there could be 36 alien civilizations in the Milky Way (see ExoArticle here). Another study this month suggested there could be as many as 6 billion “Earth-like” planets in the galaxy (see ExoArticle here).

A newly published study from NASA researchers suggests that there may be planets in the Milky Way galaxy other than Earth that have an ocean.

The research, published in Publications of the Astronomical Society of the Pacific, notes more than a quarter of the 53 exoplanets — planets outside the Solar System — that were studied could potentially be “ocean worlds,” planets that have significant amounts of water.

“Plumes of water erupt from Europa and Enceladus, so we can tell that these bodies have subsurface oceans beneath their ice shells and they have energy that drives the plumes, which are two requirements for life as we know it,” Lynnae Quick, NASA planetary scientist and the study’s lead author, said in a statement. “So if we’re thinking about these places as being possibly habitable, maybe bigger versions of them in other planetary systems are habitable too.”

Europa and Enceladus, moons that orbit Jupiter and Saturn, respectively, are icy celestial bodies that could potentially be home to extraterrestrial life.
Quick, who specializes in volcanism and ocean worlds and the other researchers looked at exoplanets similar in size to Earth, including a group of seven in the TRAPPIST-1 system, 39 light-years from Earth. A light-year, which represents distance in space, is the equivalent of about 6 trillion miles.
In addition to size, they looked at density, orbit, temperature, mass and how far the planets are from their star to come up with their conclusions.
