Giant 'forbidden planet' orbiting small star shows an unusually low-metal atmosphere
Scientists have discovered that a highly unusual giant planet—sometimes called "forbidden"—could have an atmosphere with fewer heavier elements than its host star. University of Birmingham astrophysicist Dr. Anjali Piette worked with an international research team to analyze James Webb Space Telescope data from the exoplanet TOI-5205 b. This is a Jupiter-sized planet orbiting a star about four times the size of Jupiter and about 40% the mass of the sun.

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.

How plants could betray themselves across the galaxy
Here's a thought experiment. Imagine looking at Earth from a distant star system, armed with a powerful telescope capable of capturing its reflected light. Could you tell the planet was alive? The answer, remarkably, might be yes and the clue would come from the color of the plants.
CBC Technology ScienceIn our search for alien life, stars might be muddying their signals
Humans have wondered for centuries whether we are alone in the universe — and a new study suggests that if alien civilizations have been trying to communicate with us, we mostly haven’t been listening for the right signals.

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
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.
