TRAPPIST-1e Methane Signal Likely False, Webb Data Suggests Airless Planet
The TRAPPIST-1 planetary system, located about 39 light-years from Earth, hosts seven rocky worlds orbiting a cool red dwarf star. While several of these Earth-sized planets lie in the star’s habitable zone, new observations from the James Webb Space Telescope suggest their atmospheres may be too thin to support life. Earlier hints of methane aro...

Newly Found ‘Super-Earth’ GJ 251 c Could Be One of the Most Promising Worlds for Alien Life
A new super-Earth, GJ 251 c, has been found orbiting a nearby red dwarf star within its habitable zone. About four times Earth’s mass, it may host liquid water. Detected via the radial-velocity method using Penn State’s Habitable Zone Planet Finder, it’s a prime target in the search for life.

Not Like Venus Or Mars, Distant Exoplanet May Have Atmosphere Like Earth's
A distant exoplanet might have an atmosphere similar to Earth's, early observations from the James Webb Space Telescope (JWST) suggest. It is part of a group of planets orbiting a star called TRAPPIST-1, about 40 light-years away from Earth.

NASA Telescope Detects Possible Signs Of Alien Life On Distant 'Water World'
Researchers using the Webb telescope found traces of two gases, dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), in the atmosphere of K2-18b, a planet 124 light-years away.

A New 'Earth' Next Door? Scientists Detect Possible Habitable Planet Around Closest Sun-Like Star
Astronomers using JWST have detected a giant exoplanet in the habitable zone of Alpha Centauri A, our nearest Sun-like star.

NASA Missions Uncover a Diverse Galaxy of Super-Earths, Raising New Questions About Planetary Evolution
Super-Earths are among the most common planets in the galaxy, yet none exist in our solar system. Larger than Earth but smaller than Neptune, they range from ocean-covered worlds to scorched, atmosphere-less rocks. Some orbit within habitable zones, making them prime candidates for life. NASA’s Kepler and TESS missions, along with upcoming telesc...

Habitable Zone Explained: The ‘Goldilocks Zone’ Where Life-Friendly Planets May Exist
The habitable zone, or “Goldilocks zone”, is the region around a star where conditions allow liquid water to exist. Varying with star type, this zone is key in the search for life. Earth’s location in the Sun’s habitable zone has made life possible, and astronomers seek similar rocky exoplanets in other systems to explore the possibility of...

James Webb Telescope Detects Potential Gas Giant Exoplanet Just 4 Light-Years Away
Astronomers using JWST have spotted a possible gas giant orbiting Alpha Centauri A, only 4 light-years away. If confirmed, it would be the closest exoplanet to a Sun-like star ever imaged. The discovery could challenge current models of planetary formation in binary systems and open new opportunities for studying nearby worlds.

Scientists Explore Role of Space Radiation in Powering Alien Microbial Life
A new study proposes that life may exist far from sunlight in a “radiolytic habitable zone” deep beneath the icy surfaces of Mars, Europa, and Enceladus. Cosmic rays, which can penetrate rock and ice, break water molecules apart to release hydrogen, oxygen, and energy-rich electrons. These can fuel microbes in subsurface water, much like bacter...

Exoplanet 35 Light-Years Away Offers Hope for Life Beyond Earth
The exoplanet has a minimum mass 2.8 times that of Earth and has been categorised as a super-Earth.

Alien Life May Survive on Planets Orbiting White Dwarfs, Study Finds
New research explores the possibility of alien life on planets orbiting white dwarfs. While these stellar remnants cool over time, their shrinking habitable zones may still allow biological processes like photosynthesis and UV-driven abiogenesis to occur. A model assessing a planet's energy reception over seven billion years indicates that life-sus...

Newly Confirmed Super-Earth HD 20794 d May Support Life in Habitable Zone
A super-Earth, HD 20794 d, has been confirmed within a habitable zone 20 light years from Earth. The planet, first detected in 2022, has a mass six times that of Earth and orbits a sun-like star. Although its elliptical orbit affects temperature stability, its potential to sustain liquid water makes it a key target for upcoming space missions. Scie...

NASA's James Webb Space Telescope Discovers Fourth Planet in Kepler-51 System
A study published in The Astronomical Journal reveals the discovery of Kepler-51e, the fourth planet in the Kepler-51 system, led by Dr Jessica Libby-Roberts of Penn State and Dr Kento Masuda of Osaka University. Observations indicated that only a four-planet model could explain the transit timing variations. Kepler-51e’s orbit, just inside the s...
