Exoplanet Haze Research: A Crucial Step in Understanding Alien Worlds

Posted by in categories: alien life, evolution

What is the weather like on water-rich exoplanets? This is something a recent study published in Nature Astronomy hopes to shed light on as a team of researchers conducted laboratory experiments to simulate how hazy skies might form on such exoplanets throughout the cosmos. Haze changes the way light reacts to various gases within a planet’s atmosphere, which alters what astronomers detect, as well. This study comes as the number of potential water-rich exoplanets continues to grow and holds the potential to help scientists better understand the conditions necessary for the formation and evolution of water-rich exoplanets, including how life might form and evolve on them, whether on their surfaces or in their atmospheres.

“The big picture is whether there is life outside the solar system, but trying to answer that kind of question requires really detailed modeling of all different types, specifically in planets with lots of water,” said Dr. Sarah Hörst, who is an associate professor of Earth and planetary sciences at Johns Hopkins University and a co-author on the study. “This has been a huge challenge because we just don’t have the lab work to do that, so we are trying to use these new lab techniques to get more out of the data that we’re taking in with all these big fancy telescopes.”

Unveiling Mercury’s Geological Mysteries: Salt Glaciers, Primordial Atmosphere, and the New Frontiers of Astrobiology

Posted by in category: alien life

Scientists from the Planetary Science Institute have uncovered evidence of potential salt glaciers on Mercury, opening a new frontier in astrobiology by revealing a volatile environment that might echo habitability conditions found in Earth’s extreme locales.

“Our finding complements other recent research showing that Pluto has nitrogen glaciers, implying that the glaciation phenomenon extends from the hottest to the coldest confines within our solar system. These locations are of pivotal importance because they identify volatile-rich exposures throughout the vastness of multiple planetary landscapes,” said Alexis Rodriguez, lead author of the paper “Mercury’s Hidden Past: Revealing a Volatile-Dominated Layer through Glacier-like Features and Chaotic Terrains” that appears in the Planetary Science Journal.

PSI scientists Deborah Domingue, Bryan Travis, Jeffrey S. Kargel, Oleg Abramov, John Weirich, Nicholas Castle and Frank Chuang are co-authors of the paper.

NASA is Getting the Plutonium it Needs for Future Missions

Posted by in categories: alien life, government, nuclear energy

Radioisotope Thermoelectric Generators (RTGs) have a long history of service in space exploration. Since the first was tested in space in 1961, RTGs have gone on to be used by 31 NASA missions, including the Apollo Lunar Surface Experiments Packages (ALSEPs) delivered by the Apollo astronauts to the lunar surface. RTGs have also powered the Viking 1 and 2 missions to Mars, the Ulysses mission to the Sun, Galileo mission to Jupiter, and the Pioneer, Voyager, and New Horizons missions to the outer Solar System – which are currently in (or well on their way to) interstellar space.

In recent years, RTGs have allowed the Curiosity and Perseverance rovers to continue the search for evidence of past (and maybe present) life on Mars. In the coming years, these nuclear batteries will power more astrobiology missions, like the Dragonfly mission that will explore Saturn’s largest moon, Titan. In recent years, there has been concern that NASA was running low on Plutonium-238, the key component for RTGs. Luckily, the U.S. Department of Energy (DOE) recently delivered a large shipment of plutonium oxide, putting it on track to realize its goal of regular production of the radioisotopic material.

The Incredible Sci-Fi Series You Need To Be Watching Feels Truly Alien

Posted by in category: alien life

Max’s Scavengers Reign is making waves in the science-fiction world for brilliantly conceptualizing and constructing an alien ecosystem that feels truly out of this world. Since its October 19 streaming premiere, we’ve been presented with a 12-episode run that places an exceptionally strong emphasis on the series’ setting in a way that makes the environment a more compelling character than the actual characters themselves. Scavengers Reign is a visually stunning and surreal take on humanity’s relationship with nature, and die-hard sci-fi fans can’t get enough of it.

YouTube creator NerdWriter1 posted a short breakdown of the series and grapples with the other-worldliness that Scavengers Reign presents. He likens the series’ emphasis on the environment to Werner Herzog’s documentary Burden of Dreams, in which Herzog suggests that nature is indifferent to humanity. In other words, nature has its own agenda, and the idea of harmony between humanity and nature is something that doesn’t necessarily exist when you consider how punishing an unfamiliar ecosystem can be to humans who are trying to traverse the vast landscapes full of unknown flora, fauna, and critters who rule the land.

How to think computationally about AI, the universe and everything

Posted by in categories: alien life, robotics/AI

Drawing on his decades-long mission to formulate the world in computational terms, Stephen Wolfram delivers a profound vision of computation and its role in the future of AI. Amid a debut of mesmerizing visuals depicting the underlying structure of the universe, he provides a sweeping survey of his life’s work, offering a new perspective on the applications — and consequences — of AI powered by computational language.

Harvard Professor Says Godlike Aliens May Be Creating Universes in Labs

Posted by in categories: alien life, quantum physics

In a new interview, perpetually provocative Harvard astronomer and alien hunter Avi Loeb posited both that super-human aliens could be building “baby universes” in labs and that his haters are just “jealous.”

When discussing his work and theories in a chat with Fox News, Loeb showed his tendency toward imaginative, deeply speculative theories of extraterrestrial life.

Can we refrain from inane comments about fascism? Unless you have something constructive to say I’ll probably just delete it and block you from commenting in the future. Or I might turn off comments altogether. With that out of the way, enjoy the book.
“Thousands of years in the future, a young man joins mobile infantry and fights in an interplanetary war against insect-like aliens.“

Are We Actually Living in a Multiverse? The Basic Math May Be Wrong

Posted by in categories: alien life, mathematics, particle physics

One of the most startling scientific discoveries of recent decades is that physics appears to be fine-tuned for life. This means that for life to be possible, certain numbers in physics had to fall within a certain, very narrow range.

One of the examples of fine-tuning which has most baffled physicists is the strength of dark energy, the force that powers the accelerating expansion of the universe.

If that force had been just a little stronger, matter couldn’t clump together. No two particles would have ever combined, meaning no stars, planets, or any kind of structural complexity, and therefore no life.

The Expanse is an American science fiction television series developed by Mark Fergus and Hawk Ostby for the Syfy network, and is based on the series of novels of the same name by James S. A. Corey. The series is set in a future where humanity has colonized the Solar System. It follows a disparate band of protagonists—United Nations Security Council member Chrisjen Avasarala (Shohreh Aghdashloo), police detective Josephus Miller (Thomas Jane), ship’s officer James Holden (Steven Strait) and his crew—as they unwittingly unravel and place themselves at the center of a conspiracy that threatens the system’s fragile state of cold war, while dealing with existential crises brought forth by newly discovered alien technology.
