A new, thin-lensed telescope design could far surpass JWST

Posted by in category: alien life

Astronomers have discovered more than 5,000 planets outside of the solar system to date. The grand question is whether any of these planets are home to life. To find the answer, astronomers will likely need more powerful telescopes than exist today.

I am an astronomer who studies astrobiology and planets around distant stars. For the last seven years, I have been co-leading a team that is developing a new kind of space telescope that could collect a hundred times more light than the James Webb Space Telescope, the biggest space telescope ever built.

Almost all space telescopes, including Hubble and Webb, collect light using mirrors. Our proposed telescope, the Nautilus Space Observatory, would replace large, heavy mirrors with a novel, thin lens that is much lighter, cheaper and easier to produce than mirrored telescopes. Because of these differences, it would be possible to launch many individual units into orbit and create a powerful network of telescopes.

Finding meaning at the quantum level

Posted by in categories: alien life, finance, neuroscience, particle physics, quantum physics, robotics/AI

Kmele steps inside Fermilab, America’s premiere particle accelerator facility, to find out how the smallest particles in the universe can teach us about its biggest mysteries.\
This video is an episode from @The-Well, our publication about ideas that inspire a life well-lived, created with the @JohnTempletonFoundation.\

According to Fermilab’s Bonnie Flemming, the pursuit of scientific understanding is “daunting in an inspiring way.” What makes it daunting? The seemingly infinite number of questions, with their potentially inaccessible answers.\
In this episode of Dispatches from The Well, host Kmele Foster tours the grounds of America’s legendary particle accelerator to discover how exploring the mysteries at the heart of particle physics help us better understand some of the most profound mysteries of our universe.\

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.

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.

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.
