Can we find floating vegetation on ocean planets?

Space and time from Science Daily Feed - Thu, 02/27/2025 - 9:58am
Recent advances in astronomical observations have found a significant number of extrasolar planets that can sustain surface water, and the search for extraterrestrial life on such planets is gaining momentum. A team of astrobiologists has proposed a novel approach for detecting life on ocean planets. By conducting laboratory measurements and satellite remote sensing analyses, they have demonstrated that the reflectance spectrum of floating vegetation could serve as a promising biosignature. Seasonal variations in floating vegetation may provide a particularly effective means for remote detection.

Cracking the code on solid-state batteries

Matter and energy from Science Daily Feed - Thu, 02/27/2025 - 9:50am
Researchers are working to enhance battery safety and efficiency by developing solid-state alternatives to lithium-ion batteries. These batteries offer improved energy efficiency and safety, but a major challenge has been the formation of an interphase layer at the junction of the solid electrolyte and cathode. This ultra-thin layer obstructs lithium ion and electron movement, increasing resistance and degrading battery performance.

The International Space Station is overly sterile; making it 'dirtier' could improve astronaut health

Space and time from Science Daily Feed - Thu, 02/27/2025 - 9:48am
Astronauts often experience immune dysfunction, skin rashes, and other inflammatory conditions while traveling in space. A new study suggests that these issues could be due to the excessively sterile nature of spacecraft. The study showed that the International Space Station (ISS) has a much lower diversity of microbes compared to human-built environments on Earth, and the microbes that are present are mostly species carried by humans onto the ISS, suggesting that the presence of more microbes from nature could help improve human health in the space station.

NASA's Hubble provides bird's-eye view of Andromeda galaxy's ecosystem

Space and time from Science Daily Feed - Thu, 02/27/2025 - 9:48am
Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full Moon. What backyard observers don't see is a swarm of nearly three dozen small satellite galaxies circling the Andromeda galaxy, like bees around a hive.
