When and where to see the Cold Moon, the longest and last full moon of 2023

Posted by in category: alien life

The longest — and last — full moon of the year will appear on Monday night and peak on Tuesday.

December’s full moon, also known as the Cold Moon and Long Night Moon, will reach peak illumination at 7:33 p.m. ET on Tuesday, according to NASA. It will look like a full moon until Thursday morning. The Old Farmer’s Almanac details specific moonrise times for different ZIP codes across the United States.

To view the full moon, it’s not rocket science: NASA recommends going outside and looking up at the sky. Using a telescope or binoculars will magnify the moon and clarify details on its surface.

Earth Itself May Be an Intelligent Being, Suggests New Theory

Posted by in categories: alien life, climatology, sustainability

This was suggested by Gustave Fechner and other philosophers.

How about planets? Can they have minds? This idea, that planets are also conscious beings, seems to be at the heart of a new theory put forth by astrobiologists. The premise of this thought experiment is that bacteria and plants working together have altered planets like Earth, giving them a new lease on life.

This research, published in the International Journal of Astrobiology, provides a scale by which planets’ intelligence can be evaluated. It’s shocking to consider an extraterrestrial organism intelligent rather than a sentient animal like a human. But in a way, a planet can have a “green mind”; this paradigm suggests novel approaches to coping with climate change, technological upheaval, and other emergencies.

Scientists just had a 20-minute ‘conversation’ with a humpback whale

Posted by in categories: alien life, innovation

Researchers have had an unprecedented and exceptional encounter with a humpback whale, allowing them to learn more about humpback whale communication systems. The encounter happened earlier this year when a group of researchers known as Whale-SETI held a 20-minute “conversation” with a humpback named Twain.

The conversation is heavily detailed in a paper published in the journal Peer J and it showcases the first conversation between humans and humpback whales using “humpback language.” To pull off such a wonderful breakthrough, researchers used a recorded humpback contact call to get Twain’s attention. From there, the whale responded with a greeting signal and began to circle their boat.

In the grandeur of the universe, the tapestry of life may be woven from stranger threads than we ever dared to dream, and spun from materials far different to our own.\

The First Stars and the Cosmic Dawn: A Journey to the Beginning of Time with Webb

Posted by in categories: alien life, chemistry, evolution, physics

Have you ever wondered what the universe looked like before the first stars were born? How did these stars form and how did they change the cosmos? These are some of the questions that the James Webb Space Telescope, or Webb for short, will try to answer. Webb is the most powerful and ambitious space telescope ever built, and it can observe the infrared light from the most distant and ancient objects in the universe, including the first stars. The first stars are extremely hard to find, because their light is very faint and redshifted by the expansion of the universe. But Webb has a huge mirror, a suite of advanced instruments, and a unique orbit that allows it to detect and study the first stars. By finding the first stars, Webb can learn a lot of information that can help us understand the early history and evolution of the universe, and test and refine the theoretical models and simulations of the first stars and their formation processes. Webb can also reveal new and unexpected phenomena and raise new questions about the first stars and their role in the universe. Webb is opening a new window to the cosmic dawn, where the first stars may shine. If you want to learn more about Webb and the first stars, check out this article1 from Universe Today.

Strange ‘slide whistle’ fast radio burst picked up by alien-hunting telescope defies explanation

Posted by in category: alien life

The fascinating patterns of 35 repeating fast radio bursts (FRBs) reveal new properties of these mysterious blasts of deep-space radiation that appear and disappear in milliseconds.

Scientists Contact Whales in World-First Communication Experiment

Posted by in category: alien life

What do whale experts and alien hunters have in common? More than you might expect.

For a recent study published in the peer-reviewed journal PeerJ, scientists from UC Davis, the Alaska Whale Foundation, and SETI (Search for Extraterrestrial Intelligence) teamed up.

Their mission: Communicate with whales. And they did just that.

If alien life is artificially intelligent, it may be stranger than we can imagine

Posted by in categories: alien life, robotics/AI

We’ve long assumed that aliens will be like us, but there’s every reason to think they are instead a form of unfathomable AI, says the UK astronomer royal Lord Martin Rees.

New Evidence Discovered That Saturn’s Moon Could Support Life

Posted by in category: alien life

Very interesting find. Life on Saturn’s moon would be great.

Molecules in Enceladus’s icy plumes suggest that alien life could exist in our solar system.

NASA Identifies 17 Exoplanets with Potential for Life-Supporting Oceans

Posted by in category: alien life

A recent study published in The Astrophysical Journal and presented at this week’s American Geophysical Union Annual Meeting 2023 examines how 17 exoplanets could harbor interior oceans of liquid water, and possibly even geysers, much like two moons within our solar system, Europa and Enceladus. This study was conducted by a team of researchers across academia and multiple research institutions and holds the potential to help scientists better understand the prospects and conditions for finding life beyond our solar system, including the examination of how life could form outside of a star’s habitable zone (HZ).

“Our analyses predict that these 17 worlds may have ice-covered surfaces but receive enough internal heating from the decay of radioactive elements and tidal forces from their host stars to maintain internal oceans,” said Dr. Lynnae Quick, who is a planetary geophysicist at NASA’s Goddard Space Flight Center and lead author of the study. “Thanks to the amount of internal heating they experience, all planets in our study could also exhibit cryovolcanic eruptions in the form of geyser-like plumes.”
