🪨 NEW: A #spacecraft touched an #asteroid in 2020 and plunged straight through the surface instead of stopping at it, leaving scientists asking why the #material was so soft.

💁🏻‍♀️ TIL: 🛰️🌕 #SouthKorea’s #Danuri lunar orbiter snapped #photos of a new impact site on the #moon following a high-speed collision involving a defunct #SpaceX rocket.

The resulting #crater formed near #Einstein crater along the #lunar terminator where day and night meet. #Space agency officials published the #images on social media to document the aftermath of the crash.

💁🏻‍♀️ TIL: ☄️🧂 A #meteorite that crashed through a #NewJersey home in 2024 contained preserved salts and organic compounds from its parent #asteroid, evidence of ancient brines interacting with #carbon #chemistry.

Researchers found amino acids and other #prebiotic #molecules in the rock. The findings offer new clues about how life’s building blocks may have been delivered to early #Earth.

💁🏻‍♀️ TIL: 🌱🔬 A new 3D #climate model suggests #Earth’s photosynthetic #biosphere could survive up to 1.86 billion more years, well past earlier 1 billion year estimates.

Researchers examined how rising #heat and declining #CO2 will squeeze future plant life. Hardiest survivors like CAM #plants and aquatic #algae may persist near the poles.

❛❛ something big – often called #PlanetX – might actually be out there. And a new study by a team from #Princeton University has substantially raised the likelihood that it really exists.

The evidence comes from an apparently non-random distribution in the orientation of the #orbits of smaller outer #SolarSystem bodies known as trans-Neptunian objects or #KuiperBelt objects (KBOs). ❜❜
