The Real Shape of Alien Life May Shock You | Space Documentary

Do you believe alien life could be completely unlike anything we’ve ever imagined? In this Science Documentary, we explore forms of life that may not need light, oxygen, or even a recognizable body—glowing through chemistry, drifting like gel in endless darkness, or existing as silent, stone-like structures. This Science Documentary follows the latest discoveries as telescopes probe distant worlds for signs of life. And closer to home, beneath thick ice, hidden oceans may already hold the first alien organisms humanity could reach. Join this Science Documentary as we challenge everything we think life should be.

Gemini South confirms long-suspected link between the composition of exoplanets and their host stars

Astronomers have discovered that a giant planet, WASP-189b, echoes the composition of its host star, providing the first direct evidence of a foundational concept in astrobiology. This discovery was achieved through the first-ever simultaneous measurement of gaseous magnesium and silicon in a planet’s atmosphere. The team used the Gemini South telescope, one half of the International Gemini Observatory. The findings are published in the journal Nature Communications.

Almost 320 light-years away in the Libra constellation lies WASP-189b, an exoplanet known as an ultra-hot Jupiter (UHJ). UHJs have temperatures high enough to vaporize rock-forming elements like magnesium (Mg), silicon (Si), and iron (Fe), offering a rare opportunity to see these elements using spectroscopy—the technique of breaking up light into its component wavelengths to identify the presence of chemicals.

An international team of astronomers led by Jorge Antonio Sanchez, a graduate student at Arizona State University (ASU), observed WASP-189b using the high-resolution Immersion GRating INfrared Spectrograph (IGRINS) when it was mounted on the Gemini South telescope in Chile. This powerful instrument allowed them to simultaneously measure the magnesium and silicon content of the exoplanet’s atmosphere.

Hydrogen atmosphere could keep exomoons habitable for billions of years

Liquid water is considered essential for life. Surprisingly, however, stable conditions that are conducive to life could exist far from any sun. A research team from the Excellence Cluster ORIGINS at LMU and the Max Planck Institute for Extraterrestrial Physics (MPE) has shown that moons around freefloating planets can keep their water oceans liquid for up to 4.3 billion years by virtue of dense hydrogen atmospheres and tidal heating—that is to say, for almost as long as Earth has existed and sufficient time for complex life to develop.

Planetary systems often form under unstable conditions. If young planets come too close, they can fling each other out of their orbits. This creates free-floating planets (FFPs) that wander through the galaxy without a parent star. An earlier study by LMU physicist Dr. Giulia Roccetti had shown that gas giants ejected in this way do not necessarily lose all of their moons in the process. The new study is published in the Monthly Notices of the Royal Astronomical Society.

Tidal heating keeps oceans liquid The ejection does, however, alter the orbits of the moons. They become highly elliptical, such that their distance from the planet constantly changes. The resulting tidal forces rhythmically deform the lunar body, compress its interior, and generate heat through friction. This tidal heating can be sufficient to maintain oceans of liquid water on the surface—even without the energy of a star, and in the cold of interstellar space.

Legged robot could accelerate resource prospecting on the moon and the search for life on Mars

Planetary surface missions currently operate cautiously. On Mars, communication delays between Earth and rovers (typically between four and 22 minutes), as well as data transfer constraints due to uplink and downlink limitations, force scientists to plan operations in advance. Rovers are designed for energy efficiency and safety, and to move slowly across hazardous terrain.

As a result, exploration is typically limited to only a small portion of the landing site, with rovers typically traveling up to a few hundreds of meters per day, which makes it difficult to collect geologically diverse data.

In a study published in Frontiers in Space Technologies, a team led by Dr. Gabriela Ligeza, former Ph.D. student from the University of Basel and now a postdoctoral researcher at the European Space Agency (ESA), tested a different approach: a semi-autonomous robotic explorer which can investigate multiple targets one-by-one and collect data without constant human intervention.

Where to find other Earths? New list narrows down the targets

New Cornell research – co-authored by an undergraduate and two recent alumni – will help exoplanet scientists pinpoint the most likely places to look for life in the universe out of more than 6,000 exoplanets.

The paper, “ Probing the Limits of Habitability: a Catalogue of Rocky Exoplanets in the Habitable Zone,” published March 19 in the Monthly Notices of the Royal Astronomical Society. Authors are Abigail Bohl ’26, Lucas Lawrence ’23, Gillis Lowry ’25 and Lisa Kaltenegger, professor of astronomy and director of the Carl Sagan Institute in the College of Arts and Sciences.

The project utilizes new data from the European Space Agency’s Gaia mission and the NASA Exoplanet Archive to identify planets in the habitable zone.

“The problem is in our information. Humans, yes, we are generally good and wise, but if you give good people bad information, they make bad decisions.”

Human history is a paradox: we accumulate knowledge at astonishing speed, while remaining vulnerable to deception, superstition, and the stories that steer entire civilizations.

From the first clay tablets to today’s global media systems, the structures that carry our ideas have always shaped what societies can build, believe, and destroy. That paradox is even more important in the age of AI, says Yuval Noah Harari.
