Chondrules in the chondrite classification Grassland. A millimeter scale is shown. Chondrules in the Carbonaceous Chondrite NWA 13887. A chondrule (from Ancient Greek χόνδρος chondros, grain) is a round grain found in a chondrite. Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids.
Nebula is a video-on-demand streaming service provider.Launched by the Standard Broadcast content management agency in 2019 to complement its creators' other distribution channels (primarily YouTube), [2] [3] the platform has since accumulated over 680,000 subscribers, [1] making it the largest creator-owned internet streaming platform.
Goldschmidt noted the primitive (pre-differentiated) compositions of some meteorites, calling it the "cosmic" abundance- he assumed meteorites had arrived from free space, not our Solar System. [ 28 ] [ 29 ] In turn, the study of such abundances stimulated- then validated- work in nucleosynthesis and stellar physics.
LL chondrites contain the largest chondrules of the ordinary chondrite groups, averaging around 1 millimetre (0.039 in) diameter.. The LL group includes many of the most primitive ordinary chondrites, including the well-studied Semarkona (type 3.0) chondrite.
Dos EPs is the first compilation album by the American stoner rock band Nebula. [9] [10] It was released on May 28, 2002, by MeteorCity, and later reissued in 2018 by the band's current label, Heavy Psych Sounds Records. [11] The album contains songs from the Nebula/Lowrider and Sun Creature EPs, as well as three new tracks.
Ordinary chondrite NWA 3189 sliced. Field of view c. 2.2 cm across. NWA 3189 has been classified as an LL3.2–3.4 ordinary chondrite ("LL" means very low total iron content; "3" refers to well-preserved chondrules – the rock has not been subjected to metamorphism intense enough to disrupt the chondritic texture).
Flying Lessons is a 2010 American drama film directed by Derek Magyar and starring Maggie Grace, Christine Lahti, Cary Elwes, Jonathan Tucker and Hal Holbrook. [ 1 ] [ 2 ] Synopsis
EH (high-iron) chondrites contain small chondrules (~0.2 millimetres (0.0079 in)) and high ratios of siderophile elements to silicon. Somewhat more than 10% of the rock is composed of metal grains. A diagnostic feature of EH chondrites is that the Fe-Ni metal contains ~3 wt% elemental silicon.
