Water world? Methane, carbon dioxide in atmosphere of massive exoplanet      (via sciencedaily.com) 

A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb's discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

New study reveals the power of railroads to buffer coal plants from a carbon emissions tax      (via sciencedaily.com) 

A new study suggests that railroads are likely to cut transportation prices to prop up coal-fired plants if U.S. climate policies further disadvantage coal in favor of less carbon-intensive energy sources.

Ravenous black hole consumes three Earths'-worth of star every time it passes      (via sciencedaily.com) 

Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.

Scientists detect and validate the longest-period exoplanet found with TESS      (via sciencedaily.com) 

Scientists have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and belong to a class of planets known as warm Jupiters, which have orbital periods of 10-200 days and are at least six times Earth's radius. This recent discovery offers exciting research opportunities for the future of finding long-period planets that resemble those in our own solar system.

Direct power generation from methylcyclohexane using solid oxide fuel cells      (via sciencedaily.com)     Original source 

Methylcyclohexane is very promising as a hydrogen carrier that can safely and efficiently transport and store hydrogen. However, the dehydrogenation process using catalysts has issues due to its durability and large energy loss. Recently, researchers have succeeded in using solid oxide fuel cells to generate electricity directly from methylcyclohexane and recover toluene for reuse. This research is expected to not only reduce energy requirements but also explore new chemical synthesis by fuel cells.

Mysterious Neptune dark spot detected from Earth for the first time      (via sciencedaily.com) 

Using ESO's Very Large Telescope (VLT), astronomers have observed a large dark spot in Neptune's atmosphere, with an unexpected smaller bright spot adjacent to it. This is the first time a dark spot on the planet has ever been observed with a telescope on Earth. These occasional features in the blue background of Neptune's atmosphere are a mystery to astronomers, and the new results provide further clues as to their nature and origin.

Steam condenser coating could save 460M tons of CO2 annually      (via sciencedaily.com) 

If coal and natural gas power generation were 2% more efficient, then, every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam cycle used in fossil fuel power generation could achieve this.

Hundred-year storms? That's how long they last on Saturn      (via sciencedaily.com) 

Megastorms regularly appear on Saturn, marring the relatively bland surface before disappearing. But radio observations show that the storms have long-lasting effects deeper in the atmosphere, in particular in the distribution of ammonia. Using NRAO's Very Large Array, astronomers see such impacts from storms that happened hundreds of years ago. The findings will help explain the differences between storms on the gas giants Saturn and Jupiter.

Could artificially dimming the sun prevent ice melt?      (via sciencedaily.com)     Original source 

With methods of so-called geoengineering, the climate could theoretically be artificially influenced and cooled. Researchers have now investigated whether it would be possible to prevent the melting of the West Antarctic ice sheet by artificially 'dimming the sun'. The results show that artificial influence does not work without decarbonization and entails high risks.
