If you need to stretch your mind, I recommend you check out some of the articles and videos available on the Aeon website. As the website states about its purpose:

We ask the big, existentially significant questions and find the freshest, most original answers, provided by leading thinkers on philosophy, science, psychology, society and culture.

One recently posted video with US astrobiologist Lynn Rothschild is a fascinating discussion about the difficulties in humans surviving on another planet or moon, and some of the problems and potential solutions that need to be considered. The video ends with a Q&A where Dr. Rothschild goes into a variety of related topics.

The talk itself comes from The Long Now Foundation, which has this statement about Dr. Rothschild’s talk titled “Nature’s Hardware Store”:

In her Long Now Talk, Dr. Rothschild will open the doors to “Nature’s hardware store” — a vast, largely untapped reservoir of biological strategies available to scientists, engineers, and innovators. Dr. Rothschild’s own work in recent years has included 3D-printing trees, designing fungal-based housing fit for the moon, and building synthetic cells de novo in the lab. In doing so, she has connected theoretical insights about the very nature of life on this planet with practical applications and future directions for innovation on the hardest problems facing our civilization.

The foundation has many other other great talks, including science fiction writer Kim Stanley Robinson and public policy expert Stephen Heintz talking about geopolitics here on Earth.

But getting back to Aeon, some other videos for you to explore include:

With the news seemingly on a doom loop these days, it is worth contemplating some new ideas, if only to give your mind a rest. For that reason, you need Aeon and The Long Now Foundation in your mental medicine cabinet.

Enjoy.

Space Stories: New Artemis II Photos, JWST Studies Exoplanet Surface, and Japanese Space Sake for Sale

Here are some recent space-related stories.

—ABC News: “NASA Releases More Than 12,000 Images from Historic Artemis II Moon Mission“

Over the weekend, NASA made public more than 12,000 photos from the historic Artemis II lunar mission…Over the course of the mission, NASA released dozens of images of the astronauts, Earth, the moon and even a total solar eclipse. However, the new trove reveals some never-before-seen photos as well as new angles of objects in space, primarily using Nikon cameras and iPhone 17s.

—ZME Science: “Astronomers Determine the Surface of a Rocky Planet Beyond Our Solar System for the First Time“

A rocky planet nearly 50 light-years away appears to be airless, dark, and covered in volcanic or weathered rock, according to new observations from the James Webb Space Telescope. This is the first time that astronomers have obtained details about the surface of a rocky planet outside our solar system. The planet, LHS 3844 b, is not habitable. It is about 30 percent larger than Earth, orbits its star every 11 hours, and has one side permanently pointing towards the Sun, baked at about 725°C.

—The Korean Times: “Space-fermented Sake by Japanese Brewer Dassai Sells for $700,000“

Japanese brewer Dassai has sold a 100-milliliter bottle of sake fermented on the International Space Station for 110 million yen ($700,000). Dassai partnered with Mitsubishi Heavy Industries to ferment sake ingredients in space, the Yomiuri Shimbun newspaper reported Monday. Using the space-fermented mash, or moromi, the brewery finished brewing the sake on Earth, yielding 116 milliliters. Dassai sold a 100-milliliter bottle of the final product to an unnamed Japanese buyer. The company plans to donate the proceeds to Japan’s space program.

Study Findings: A Second Visit to Eps Ind Ab with JWST: New Photometry Confirms Ammonia and Suggests Thick Clouds in the Exoplanet Atmosphere of the Closest Super-Jupiter

The Astrophysical Journal Letters abstract of study findings:

With JWST, we are directly imaging cold (∼200–300 K) solar-age giant exoplanets for the first time. At these temperatures, many molecular features appear, and water-ice clouds may condense and affect the emission spectrum; early photometric measurements of cold giant planets are already showing some tension with the predictions of cloud-free solar-metallicity atmosphere models. Here, we present new JWST/MIRI coronagraphic observations of the cold giant exoplanet Eps Ind Ab at 11.3 μm. Together with archival data, we use these new observations to study the atmosphere of this cold exoplanet, and we also refit its orbit, finding an updated mass of 7.6  ±  0.7MJup and an eccentricity of 0.24 +0.11/-0.08. The planet is significantly brighter (by 0.88  ±  0.08 mag) at 11.3 μm than at 10.6 μm, indicating the presence of ammonia. However, this ammonia feature is shallower than expected. This could indicate a low-metallicity or nitrogen-depleted atmosphere, but our preferred explanation is the presence of thick water-ice clouds that suppress the ammonia feature and the near-IR emission of Eps Ind Ab. Photometry of the small but growing sample of cold giant exoplanets demonstrates that they are consistently fainter than expected between 3 and 5 μm, consistent with the water-ice cloud hypothesis. 10.6 μm and 11.3 μm photometry of this cold exoplanet sample would be valuable to determine whether the suppressed ammonia feature is universal, and to frame a new open question about the underlying physical cause.

Space Stories: A New Type of Telescope to Spot Exoplanets, Walking Martian Robots, and Terraforming Mars in 15 Years

Here are some recent space-related stories.

—Astronomy.com: “Could this Telescope Find Life on Alien Worlds?“

The ExoLife Finder (ELF) looks like no telescope ever built. A spectacular crown of 15 five-meter mirrors perches atop a sprawling metal lattice, resembling petals on a 10-story-tall mechanical flower — more sculpture than observatory. It is a fundamentally new type of telescope, one that its designers say could discover life on Earth-like planets beyond our solar system. The radical design is the brainchild of astrophysicist Jeff Kuhn of the University of Hawai‘i. For now, it exists only in renderings. To build it, Kuhn and the team he’s assembled must first develop and perfect techniques and technologies never before used in astronomy.

—EarthSky: “Walking Robots on Mars Could Speed Up Life Search“

Robotic rovers have become the go-to way to explore our neighbor planet, Mars. And they’ve been super successful. But they’re also big, heavy and slow. They have to move carefully across the rocky and sandy terrain of Mars. Plus, communication delays between the rovers and Earth – and data transfer limitations – also affect their missions. Is there a better way? On March 31, 2026, researchers in Switzerland and the Netherlands announced a new idea: walking Mars robots. The research team said these robotic explorers would be semi-autonomous. This means they wouldn’t need regular assistance from humans back on Earth. And, their makers say, they could explore their surroundings – on both Mars or the moon – faster than rovers.

—The Times of India: “Mars Could be Warm Enough for Humans in 15 Years; A Discovery that Changes Everything“

Mars has been viewed as a multi-millennial effort to terraform since the inception of the term, but there is new evidence that the time frame has changed dramatically. A published study in Science Advances gives new hope to those wishing to terraform Mars through nanoscopic engineered aerosol-like dust particles made from iron and aluminium found abundantly in the soils of Mars. Specifically, scientists feel that if we inject these engineered aerogels into the atmosphere, the resulting greenhouse effect will raise Mars’ surface temperature by over 50 degrees Fahrenheit in only 15 years.

Surviving on an Ice Planet

Aeon always has some great articles every month, and one of these is titled “The Snowball Effect.”

The article discusses two periods when glaciers covered the Earth from pole to equator. The last time was 645 million years ago, with the ice remaining for about 10 million years. Even so, life survived and diversified under these conditions on a super-continent called Rodinia.

It may offer some lessons to us when we are looking at our Solar System’s moons as well as distant exoplanets wondering about the presence of life beneath a frozen surface. If the Earth was a snowball for millions of years before life as we know it came to be, it makes sense it would be the case elsewhere.

I recommend you review this article as well as others on Aeon. It is worth your time.
