NASA finds Titan’s alien lakes may be creating primitive cells

Saturn’s moon Titan may be more alive with possibilities than we thought. New NASA research suggests that in Titan’s freezing methane and ethane lakes, simple molecules could naturally arrange themselves into vesicles—tiny bubble-like structures that mimic the first steps toward life. These compartments, born from splashing droplets and complex chemistry in Titan’s atmosphere, could act like primitive cell walls.

NASA research has shown that cell-like compartments called vesicles could form naturally in the lakes of Saturn’s moon Titan.

Titan is the only world apart from Earth that is known to have liquid on its surface. However, Titan’s lakes and seas are not filled with water. Instead, they contain liquid hydrocarbons like ethane and methane.

Laser reveals sound from supersonic molecules in near-space cold conditions

What happens when you hurl molecules faster than sound through a vacuum chamber nearly as cold as space itself? At the University of Missouri, researchers are finding out—and discovering new ways to detect molecules under extreme conditions.

The discovery could one day help chemists unravel the mysteries of astrochemistry, offering new clues about what the universe is made of, how stars and planets form and even where life originated.

In a recent study published in The Journal of Physical Chemistry A, Mizzou faculty member Arthur Suits and doctoral student Yanan Liu fired a laser at methane gas molecules moving faster than the in a at roughly −430°F, close to the temperature in parts of outer space.

Habitable planet potential increases in the outer galaxy

What can the galactic habitable zone (GHZ), galactic regions where complex life is hypothesized to be able to evolve, teach scientists about finding the correct stars that could have habitable planets?

This is what a recent study accepted for publication in Astronomy & Astrophysics hopes to address as an international team of researchers investigated a connection between the migration of stars, commonly called stellar migration, and what this could mean for finding habitable planets within our galaxy. This study has the potential to help scientists better understand the astrophysical parameters for finding habitable worlds beyond Earth and even life as we know it. The findings are published on the arXiv preprint server.

For the study, the researchers used a series of computer models to simulate how stellar migration could influence the location and parameters of the GHZ. The models included scenarios both with and without stellar migration to ascertain the statistical probabilities for terrestrial (rocky) planets forming around stars throughout the galaxy. The researchers also used a chemical evolution model to ascertain the formation and evolution of our galaxy, specifically regarding its thickness.

The Case for Life on Mars Just Got Stronger

“This finding by Perseverance …is the closest we have ever come to discovering life on Mars,” said acting NASA administrator Sean Duffy in a statement. “The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars.”

Perseverance did not discover fossilized microbes and it surely didn’t discover living ones. What it found was a rock streaked in a range of colors—red, green, purple, and blue—flecked with poppy-seed-like dots and decorated with what the Perseverance scientists compared to dull yellow leopard spots. That said a lot. As the rover’s instruments confirmed, the red is iron-rich mud, the purple is iron and phosphorous, the yellow and green are iron and sulfur. All of those elements serve as something of a chow line for hungry microbes.

The poppy seeds and leopard spots, meantime, resemble markings left behind by metabolizing microbes on Earth. When the rover trained its instruments on those features they detected two iron-rich minerals—vivianite and greigite. On Earth, vivianite is frequently found in peat bogs and around decaying organic matter—another item on the microbes’ menu. And both minerals can be produced by microbial life. Images of the rock with its distinctive features were beamed back to Earth by Perseverance, while X-ray and laser sensors analyzed the chemistry of the markings.

What if everything we know about computing is on the verge of collapsing? Physicist Michio Kaku explores the next wave that could render traditional tech obsolete: Quantum computing.

Quantum computers, Kaku argues, could unlock the secrets of life itself: and could allow us to finally advance Albert Einstein’s quest for a theory of everything.

In this episode, I speak with Stephen Wolfram—creator of Mathematica and Wolfram Language—about a “new kind of science” that treats the universe as computation. We explore computational irreducibility, discrete space, multi-way systems, and how the observer shapes the laws we perceive—from the second law of thermodynamics to quantum mechanics. Wolfram reframes Feynman diagrams as causal structures, connects evolution and modern AI through coarse fitness and assembled “lumps” of computation, and sketches a nascent theory of biology as bulk orchestration. We also discuss what makes science good: new tools, ruthless visualization, respect for history, and a field he calls “ruliology”—the study of simple rules, where anyone can still make real contributions. This is basically a documentary akin to The Life and Times of Stephen Wolfram. I hope you enjoy it.

If Aliens Are Looking for Us, This Is How They’d Find Us

A new study of human deep space communications identifies the regions of space where signals from extraterrestrial intelligence are most likely to be detected. If an extraterrestrial civilization were trying to detect human signals, where and when would they be most likely to find them? A recent

Using exoplanets to study dark matter

More than 5,000 planets have been discovered beyond our solar system, allowing scientists to explore planetary evolution and consider the possibility of extraterrestrial life. Now, a UC Riverside study published in Physical Review D suggests that exoplanets, which are planets orbiting stars outside our solar system, could also serve as tools to investigate dark matter.

The researchers examined how dark matter, which makes up 85% of the universe’s matter, might affect Jupiter-sized exoplanets over long periods of time. Their theoretical calculations suggest dark matter particles could gradually collect in the cores of these planets. Although dark matter has never been detected in laboratories, physicists are confident it exists.

“If the dark matter particles are heavy enough and don’t annihilate, they may eventually collapse into a tiny black hole,” said paper first author Mehrdad Phoroutan-Mehr, a graduate student in the Department of Physics and Astronomy who works with Hai-Bo Yu, a professor of physics and astronomy. “This black hole could then grow and consume the entire planet, turning it into a black hole with the same mass as the original planet. This outcome is only possible under the superheavy non-annihilating dark matter model.”

Circle versus rectangle: Finding ‘Earth 2.0’ may be easier using a new telescope shape

The Earth supports the only known life in the universe, all of it depending heavily on the presence of liquid water to facilitate chemical reactions. While single-celled life has existed almost as long as Earth itself, it took roughly three billion years for multicellular life to form. Human life has existed for less than one-10 thousandth of the age of Earth.

All of this suggests that life might be common on planets that support liquid water, but it might be uncommon to find life that studies the universe and seeks to travel through space. To find extraterrestrial life, it might be necessary for us to travel to it.

However, the vastness of space, coupled with the impossibility of traveling or communicating faster than the , places practical limits on how far we can roam.
