Exomoons Could Be Habitable for Billions of Years, Provided they have Hydrogen Atmospheres

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 free-floating 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.

Mars-Like Worlds Near M-Dwarfs May Lose Air in Millions of Years https://www.universetoday.com/articles/mars-like-worlds-near-m-dwarfs-may-lose-air-in-millions-of-years 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science #SolarSystem #Astrobiology

Mars-Like Worlds Near M-Dwarfs May Lose Air in Millions of Years

The criteria for finding an Earth-like planet unofficially comes down to two things: water and the habitable zone. But a phenomenon known as atmospheric escape often “escapes” the minds of many astronomy fans, and it turns out that atmospheric escape is one of the key characteristics for finding an Earth-like world. Although extensive research has been conducted on how the planet Mars might have lost its atmosphere, and potentially the ability to sustain life, how would the atmosphere enveloping a Mars-like exoplanet respond to stars different from our own?

Direct confirmation of two baby planets forming around a young, sun-like star

As the number of exoplanet detections has breached 6,000 and continues to grow, scientists are finding a wide variety of different solar system architectures. Critical to understanding how these architectures take shape is finding young planets forming around very young stars. In 2025, a team of astronomers announced the discovery of a planet about five times more massive than Jupiter around a star that's very much a younger version of our sun.

AI approach uncovers dozens of hidden planets in NASA's TESS data

Astronomers at the University of Warwick have validated over 100 exoplanets, including 31 newly detected planets, using a new artificial intelligence tool applied to data from NASA's Transiting Exoplanet Survey Satellite (TESS), a space mission that monitors the sky for the subtle dimming of starlight caused when planets pass in front of their host stars.

The president promised to spill the beans about little green men. Is that why the US Cybersecurity and Infrastructure Security Agency registered the domains alien.gov and aliens.gov, asks Arwa Mahdawi

Moons orbiting wandering exoplanets could be habitable—with one catch https://phys.org/news/2026-03-moons-orbiting-exoplanets-habitable.html 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science #SolarSystem #Astrobiology

Moons orbiting wandering exoplanets could be habitable—with one catch

Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck Institute for Extraterrestrial Physics and Giulia Roccetti at the European Space Agency, a new study predicts that hydrogen could act as a potent greenhouse gas—potentially providing habitable conditions for billions of years after their host planets are first ejected from their stellar systems. The work has been published in Monthly Notices of the Royal Astronomical Society.

What 'Project Hail Mary' gets right—and wrong—about astrophysics

"Project Hail Mary," the Ryan Gosling-led adaptation of the best-selling sci-fi novel from Andy Weir, is being praised for putting the science in science fiction. Although aliens, sun-draining microorganisms and galaxy-spanning spaceflight are all a part of the story of a scientist sent on a suicide mission to save Earth, the film and its source material are not afraid to delve into the kind of astrophysics that would make most people's heads spin.

The best places to look for alien life: Scientists identify 45 Earth-like worlds to explore for a 'Project Hail Mary'

If we're to find extraterrestrial life in the universe, astronomers have pinpointed the best places to look for it. They have identified just under 50 rocky worlds most likely to be habitable out of the more than 6,000 exoplanets discovered so far.
