📣 Scientists using Hubble have uncovered a new type of astronomical object! 

This starless, dark-matter-dominated cloud is a relic from the early Universe, a failed galaxy.

Entry #2849 why scientific publishing is broken

"with the journal [now publishing] nearly 10k articles annually. ...there was a perverse incentive to accept mediocre work: to publish research open access in the journal, a scientist has to pay $4,150 plus taxes."🧪

STUDYING CHONDRITIC #METEORITES WE TRAVEL BACK IN TIME to the first stages in Solar System formation. In fact, undifferentiated asteroids formed 4.5 Gyrs ago & never melted, being the parent bodies of #chondrites. I'm briefly introducing you to these rocks made of chondrules

INTRODUCING YOU TO CV3 CHONDRITE #ALLENDE: A pristine member of the Vigarano group, then classified as CV3. It is mostly formed by chondrules, and refractory inclusions. The last ones can be even cm-sized like the one shown, and are known as Ca- and Al-rich inclusions (CAIs)

A 15 g specimen of Allende still preserving its fusion crust. A part was sectioned and polished to show the rounded chondrules, and the irregular white inclusions called CAIs (Josep M. Trigo/CSIC/IEEC) A cm-sized CAI surrounded by accreted chondrules, creating this authentic sedimentary rock of the "creation"
