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...

JWST Reveals Pluto’s Haze Cools Atmosphere, Paints Charon’s Poles Red
Pluto's thin haze of organic particles, confirmed by JWST’s mid-infrared observations, plays a crucial role in both cooling its mesosphere and launching methane into space. This methane escapes Pluto’s gravity, landing on Charon’s poles where radiation transforms it into reddish tholins. The study highlights how Pluto’s haze shapes not only...

James Webb Telescope Maps Fiery Atmosphere of Turbulent Exoplanet WASP-121b
NASA’s James Webb Space Telescope has unveiled the turbulent history of WASP-121b, a scorching exoplanet distorted by its star’s gravity. New atmospheric data reveals unusual molecules like silicon monoxide and methane, shedding light on the planet’s violent migration and extreme climate. These findings challenge current models and enhance un...

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 ...

Greenhouse Gas is Rising Rapidly in Atmosphere Due to Human Activities, Highlights New Report
Methane levels, which are 80 times more potent than CO2 in the short term, are rising at an unprecedented rate. Human activities, such as agriculture and fossil fuel extraction, contribute significantly to this surge. Despite global efforts, including the 2021 Global Methane Pledge, methane emissions continue to climb. This trend threatens climate ...

NASA's New Horizons Data Helps Identify a Possible Source for Pluto's Moon Charon's Red Cap
NASA's New Horizons mission data along with novel laboratory experiments and exospheric modelling has helped scientists to reveal the likely composition of the red cap on Pluto's moon Charon and how it may have formed. The team realistically replicated Charon surface conditions to measure the composition and colour of hydrocarbons produced on Charo...

Mysterious Plumes of Methane Gas Appear Over Bangladesh: "It's A Signal"
One of the countries most vulnerable to climate change has also been revealed as a major contributor of methane, a greenhouse gas that's about 80 times more potent in its first two decades in the atmosphere than carbon dioxide.
