Astronomers are raising alarms over plans to launch tens of thousands of sunlight-reflecting satellites, with FCC approval reportedly in question. 'They're saying we want to launch 50,000 mirrors by 2035,' Benvenuti said. 'That would be catastrophic for astronomy, that is clear.' Critics say the mirrors would flood the night sky with artificial light and permanently interfere with ground-based observations of the universe.
- 2Pollution threatening deep sea bioluminescent life, experts warn●More plastic, less glow? Pollution threatens deep sea’s bioluminescent life, experts warn
Environmental experts are warning that plastic pollution in the deep ocean may be interfering with the bioluminescent organisms that live there. Pollution particles could block or mimic the light signals deep sea species rely on for feeding, mating and defence, potentially disrupting entire ecosystems in one of the planet's least explored environments.

Light pollution from cities is erasing natural darkness, and with it the night sky that humans have lived under for millennia. The Guardian reports that artificial light now spreads across urban areas so thoroughly that most people rarely experience genuine darkness, prompting discussion about stronger regulation of outdoor lighting and its effects on health, wildlife and stargazing.

Light pollution is making the night sky roughly 10% brighter each year, erasing natural darkness from urban life. Commenters and climate writers are urging cities to regulate outdoor lighting, arguing that darker streets would benefit wildlife, human health and the environment. The discussion is part of wider concern about how human activity is altering the natural world.
- 5Light pollution is making starry night skies harder to find●It's amazing when you're camping miles from any civilization on a clear night and can see lots and lots of stars. But it
Campers and stargazers are noting that seeing a sky full of stars far from cities is getting harder, pointing to a Guardian report on night-sky darkness and city light regulation. Growing light pollution from urban areas is dimming the view of the stars even in remote places, prompting calls for stricter rules on artificial lighting.

Researchers have examined how sea squirts detect and respond to underwater noise, shedding light on how marine invertebrates sense sound in their environment. The work suggests these filter-feeding animals may be more sensitive to human-made ocean noise, such as shipping, than previously assumed. The findings add to growing concern about the impact of noise pollution on sea life.
- 7Night skies brightening 10% a year as darkness fades●The night sky is getting 10% brighter every year. We're forgetting darkness
Light pollution is causing the night sky to grow roughly 10% brighter each year, erasing the natural darkness that stars depend on. The Guardian reports on how cities' outdoor lighting and weak regulation are driving the change, prompting concern among astronomers and environmentalists who say people are losing their connection to the dark sky.

Light pollution is increasing sharply, with the night sky reportedly brightening by around 10% each year as city lighting grows and regulations on outdoor illumination remain weak. The issue is being framed not only as an environmental concern for stargazing and wildlife, but also as a health problem, since excess artificial light at night is linked to disrupted sleep and other effects on human wellbeing.

New reporting highlights that the night sky is growing roughly 10% brighter each year, far faster than previously estimated, as artificial light pollution spreads worldwide. The concern is that an entire generation is losing the ability to see stars and natural darkness, with effects on wildlife, human sleep and cultural heritage. Commenters and scientists are calling for better lighting policies and darker-sky protections.
