Radio waves from the satellites are "blinding" radio telescopes and hurting research, say scientists.

‘Starlink killing atmosphere?’: The environmental threat to Earth Elon Musk isn’t talking about
Fiery Showers
Invisible Threat
While mesmerizing, satellite re-entries release aluminium oxide nanoparticles, which could impact the ozone layer for decades before we see the damage.
Space Junkies
With 8,000+ Starlink satellites launched and 42,000 planned, the growing mega-constellations pose a new kind of atmospheric pollution risk.
Ozone Killers?
Scientists fear aluminium oxide from re-entering satellites may act like CFCs, accelerating ozone depletion—just as we thought recovery was near.
Raining Metal
Each Starlink satellite leaves behind 30 kg of aluminium oxide. By 2050, this could reach 360 metric tonnes annually—six times natural levels.
Delayed Doom
Simulations suggest these particles could take 20-30 years to reach the stratosphere, meaning today’s pollution may haunt future generations.
Legal Loophole
No global laws regulate atmospheric pollution from satellite re-entries. The FCC approves launches but ignores the environmental impact.
Orbital Overload
Amazon, SpaceX, and other companies plan tens of thousands of satellites, but no one has a long-term plan for their safe disposal.
Debris Crisis
ESA’s “Zero Debris” initiative aims to prevent new orbital waste by 2030, but without global cooperation, space junk and ozone risks may persist.

Elon Musk's SpaceX satellites 'falling from the sky' after massive solar storms
Scientists have warned that solar storms could cause Starlink satellite parts to fall to Earth and hit the ground

‘Starlink killing atmosphere?’: The environmental threat to Earth Elon Musk isn’t talking about
Starlink satellites burn up, creating artificial meteor showers—but they release aluminum oxide, potentially damaging Earth’s ozone layer for decades. An unseen threat looms.

Hexanitrogen is a newly synthesized molecule composed entirely of nitrogen atoms, making it the first known neutral polynitrogen species other than N₂. It stores a large amount of energy in its strained bonds and decomposes cleanly into nitrogen gas, offering potential as a high-energy...
Inside Mahindra EV factory. A bit cheesy but it shows how India is competing against China for the future of car making.
@MikelBikel, that factory runs on green electricity, power factor 0.98 so not generating much harmonics, has storage batteries on site recycle and treat water on site. Metal waste is reprocessed in a week. Each EV saves 42% carbon footprint compared to older factories.

Fish and chips for 20p? The unearthed menu frozen in time
www.bbc.co.uk
A massive decline in migratory fish populations
"A jaw-dropping new study found a catastrophic 81% decline in the global population of migratory freshwater fish over the last 50 years.
That bears repeating: 81% of the fish are gone.
In some regions, the decline has been more than 90%. One quarter of these species could disappear entirely."
