NASA may be quietly gutting an iconic campus with what it calls strategic closures, workers fear | CNN Buildings at Goddard’s Maryland campus are being emptied and padlocked, sources say. NASA leadership has pushed back against the concerns.

Have you heard about this?

"As the govt shutdown drags on, buildings at NASA's Goddard Space Flight Center (HQ for the Webb telescope among other missions) are being emptied without notice. Highly specialized equipment is at risk of being thrown away like trash."

UN agency: CO2 levels hit record high last year, causing more extreme weather Heat-trapping carbon dioxide levels in the atmosphere jumped by the highest amount on record last year, soaring to a level not seen in human civilization and β€œturbo-charging” the Earth’s climate and c...

The World Meteorological Organization said in its latest bulletin on greenhouse gases that CO2 growth rates have now tripled since the 1960s, and reached levels that existed more than 800,000 years ago. https://to.pbs.org/4hfXYIv

Trump's budget proposal for NASA zeros out the Orbiting Carbon Observatory (OCO-2 & 3), which would mean an early end to tools that provide detailed information on carbon dioxide emissions and plant growth.

This might look like a double-bladed lightsaber, but these two cosmic jets actually beam outward from a newborn star in a galaxy near you. Constructed from Hubble Space Telescope image data, the stunning scene spans about half a light-year across Herbig-Haro 24 (HH 24), some 1,300 light-years or 400 parsecs away in the stellar nurseries of the Orion B molecular cloud complex. Hidden from direct view, HH 24's central protostar is surrounded by cold dust and gas flattened into a rotating accretion disk. As material from the disk falls toward the young stellar object, it heats up. Opposing jets are blasted out along the system's rotation axis. Cutting through the region's interstellar matter, the narrow, energetic jets produce a series of glowing shock fronts along their path.

Mineralization of captured perfluorooctanoic acid and perfluorooctane sulfonic acid at zero net cost using flash Joule heating - Nature Water Activated carbon has been widely used for PFAS adsorption, but this method generates secondary solid wastes. The flash Joule heating approach realizes mineralization of PFAS and generation of useful f...

Scientists have found a super-fast way to destroy toxic 'forever chemicals' in water filters. Using a quick burst of electricity, they remove 99.9% of PFAS – and turn the waste into valuable graphene.

Microplastics pollution from glitter can disrupt marine biomineralization New research reveals that PET-based glitter microplastics can actively influence biomineralization processes in marine environments, raising fresh concerns about the long-term environmental impact of microplastic pollution on marine ecosystems.

PET-based glitter microplastics can accelerate calcium carbonate crystallization in marine environments, potentially impacting marine biomineralization and increasing microplastic fragmentation. doi.org/g9bjxs

At the equinox of 20 March 2025, our planet is neither tilted towards nor away from the Sun, creating nearly equal day/night. This stunning Meteosat-12 image taken earlier this morning showcases the boundary between day and night running straight through the poles.

🌍 Happy #Equinox! On 20 March 2025 at 09:01 GMT/10:01 CET, just a few moments ago, the Sun appeared directly above Earth's equator - with our planet neither tilting towards nor away from the Sun!
