About 40,000 metric tons of #extraterrestrial material rain down on planet Earth 🌍 every year. Sometimes those #meteorites ☄️ are relatively large: boulder-sized chunks of iron or small, blackened rocks. But most of the material arrives here in the form of #micrometeorites https://www.astronomy.com/science/thinking-small-uncovering-the-secrets-of-micrometeorites/

Thinking small: Uncovering the secrets of micrometeorites

A new project is aiming to trace micrometeorites - tiny, melted remnants of space rocks that plummeted to Earth - back to their origin.

Roughly 1,600 tons of #micrometeorites and 3,600 tons of cosmic spherules reach the surface every year. Lower density and higher porosity suggest a #cometary ☄️ origin, and higher density and lower porosity suggest a #meteoritic origin https://www.sciencealert.com/5-200-tons-of-micrometeorites-are-raining-down-on-earth-s-surface-every-year

5,200 Tons of Extraterrestrial Dust Rain Down on Earth Every Single Year

We've known for a while that Earth is under a constant rain of space dust, and that it's copious.

Les micrométéorites, et non le vent solaire, seraient responsables de l'érosion lunaire. Découverte qui change notre vision de la Lune. https://www.tameteo.com/actualites/astronomie/la-veritable-cause-de-l-erosion-lunaire-n-est-pas-le-vent-solaire-selon-une-nouvelle-recherche-astronomie.html #Space #Science #Innovation #Astrophysics #LunarSurface #Micrometeorites #Exosphere

La véritable cause de l’érosion lunaire n’est pas le vent solaire, selon une nouvelle recherche

Pendant des décennies, on a cru que le vent solaire était le grand responsable de l’arrachage des atomes à la surface de la Lune.

China Says It May Have Solved a Mystery on the Moon’s Surface

Ferric iron was assumed to be rare on the moon, but samples returned by China's Chang'e-5 mission suggest it may really be abundant.

#JWST suffered a large than expected micrometeorite impact. It's still fine.

"Between May 23 and 25, NASA’s James Webb Space Telescope sustained an impact to one of its primary mirror segments.
[...]
This most recent impact was larger than was modeled, and beyond what the team could have tested on the ground."
