Metals are critical to life. We should screen exoplanets for them phys.org/news/2025-09-metals-c 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science

phys.orgMetals are critical to life. We should screen exoplanets for themLife is complicated, and not just in a philosophical sense. But one simple thing we know about life is that it requires energy, and to get that energy it needs certain fundamental elements. A new paper published in The Open Journal of Astrophysics by Giovanni Covone and Donato Giovannelli from the University of Naples discusses how we might use that constraint to narrow our search for stars and planets that could potentially harbor life. To put it simply, if it doesn't have many of the constituent parts of the "building blocks" of life, then life probably doesn't exist there.

Universe TodayPhotochemistry and Climate Modeling of Earth-like ExoplanetsWhat role can the relationship between oxygen (O2) and ozone (O3) in exoplanet atmospheres have on detecting biosignatures? This is what a recent study submitted to Astronomy & Astrophysics hopes to address as an international team of researchers investigated novel methods for identifying and analyzing Earth-like atmospheres. This study has the potential to help scientists develop new methods for identifying exoplanet biosignatures, and potentially life as we know it.

"Soot Planets" Might Be More Common Than "Water Worlds" universetoday.com/articles/soo 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science

Universe Today"Soot Planets" Might Be More Common Than "Water Worlds"According to astronomers, water worlds, though admittedly not those containing Kevin Costner, are one of the most common types of planets in our solar system. This is partly due to low density estimates and the abundance of water ice past the “snow line” orbit of a star. But a new paper led by Jie Li and their colleagues at the University of Michigan, suggests there might be an alternative type of planet that fits the density data but is made up of a completely different type of material - soot.

GJ 1132 b Doesn't Have An Atmosphere, According To New JWST Data universetoday.com/articles/gj- 🪐 #Exoplanet #Exoplanets #AlienWorlds #AlienLife #Extraterrestrials #Space #Science

Universe TodayGJ 1132 b Doesn't Have An Atmosphere, According To New JWST DataAstronomers sometimes find conflicting data when trying to answer a question. This is a normal part of the scientific process, and it simply means that more data is needed to prove or disprove the theory they are trying to test. One prominent example of conflicting data in recent exoplanet research was that of planet GJ 1132 b, which either had or didn’t have an atmosphere, depending on which data set was being used. A new paper from researchers using more observational time on the James Webb Space Telescope (JWST) can now definitively say that, most likely, GJ 1132 b doesn’t have an atmosphere - and that finding has wider implications for exoplanet research more generally.

🚀 Where Science Meets Sci-Fi: Could Alien Life Exist on K2-18b? 🌌

For decades, science fiction has imagined alien civilizations on distant worlds.

Now, real cosmologists studying exoplanet K2-18b have found compelling circumstantial evidence that hints at the possibility of extraterrestrial life.

Is this the first real step toward answering humanity’s biggest question: Are we alone in the universe?

UK is Considering a Mission to Venus to Search for Life universetoday.com/articles/uk- 🪐 #AlienLife #Extraterrestrials #Space #Science #SolarSystem

Universe TodayUK is Considering a Mission to Venus to Search for LifeIs there life on Venus? The controversial detection of phosphine and ammonia hints that bacterial life could be surviving in the planet's milder upper atmosphere. But to confirm its existence, we'll need to measure the atmosphere directly. A new mission concept was recently unveiled called the Venus Explorer for Reduced Vapours in the Environment (VERVE). It's a CubeSat that could fly with ESA's EnVision mission in 2031, studying the atmosphere for more evidence of active biology.
