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.

NASA Data Shows Pluto’s Equator Is Lined with Towering Methane Ice Spires
New research based on New Horizons’ decade-old data has uncovered extensive bladed terrain made of methane ice on Pluto. These towering spires, arranged in spaced-out, parallel rows, are likely shaped by seasonal condensation and sublimation cycles. While the terrain spans over half the planet’s midsection, five times the width of continental U...

New Dwarf Planet Discovery Challenges Planet Nine Hypothesis
The discovery of a potential dwarf planet, 2017 OF201, in the farthest reaches of the solar system is reshaping our understanding of space. With a highly elongated orbit and large size, it contradicts the Planet Nine hypothesis, which predicted orbital clustering among distant objects. This finding not only questions the existence of a ninth planet...

Astronomers Detect Methane in the Atmosphere of the Nearest T Dwarf Star to Earth
Astronomers have detected methane in the nearest known T dwarf, offering new insight into its atmospheric composition. The study further highlights that the carbon abundance in the planet is estimated to be -1.5 dex, while the effective temperature could be around 1,000 K. The author of the paper further revealed that the low metallicity of the T ...

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...

James Webb Space Telescope Observes Mysterious Rogue Planet-Like Object
The James Webb Space Telescope has captured new insights into SIMP 0136, a planetary-mass object floating freely around 20 light-years away. This celestial body, possibly a rogue planet or a brown dwarf, has puzzled astronomers for years. JWST’s infrared observations have revealed intricate cloud layers, temperature shifts, and potential chemical...

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals
A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

James Webb Space Telescope Reveals Unique Features of Westerlund 1 Star Cluster
The James Webb Space Telescope has captured groundbreaking images of Westerlund 1, a supermassive star cluster located 12,000 light-years away. The new findings offer a closer look at star formation processes, particularly the discovery of brown dwarfs, and highlight the role of energetic radiation in shaping planetary environments.

Astronomers Successfully Detect Brown Dwarfs in a Distant Star Cluster
For the first time, astronomers have detected brown dwarfs outside the Milky Way in the star cluster NGC 602, situated approximately 200,000 light-years away in the Small Magellanic Cloud. Utilising the James Webb Space Telescope (JWST), the team sought young brown dwarf candidates in an environment that resembles the early universe, with limited h...

NASA Citizen Scientists Discover Mysterious Object Moving out of Milky Way at an Extremely High Speed
On August 15, 2024, NASA’s Backyard Worlds: Planet 9 project, featuring the contributions of dedicated citizen scientists, made a groundbreaking discovery: an object moving at an astonishing speed of 1 million miles per hour, which will soon escape the gravitational pull of the Milky Way. This hypervelocity object, catalogued as CWISE J124909.08+...
