Comet samples returned to Earth by the NASA Stardust mission have provided a surprising
glimpse into the nature of early Solar System materials and an epiphany on the origin of the …

Context. We investigate the formation and evolution of comet nuclei and other trans-
Neptunian objects (TNOs) in the solar nebula and primordial disk prior to the giant planet …

We discuss the relationship between large cosmic dust that represents the main source of
extraterrestrial matter presently accreted by the Earth and samples from comet 81P/Wild 2 …

The solid 2–10 μm samples of comet Wild 2 provide a limited but direct view of the solar
nebula solids that accreted to form Jupiter family comets. The samples collected by the …

Transmission electron microscopy examination of 87 large fragments from 16 carrot‐shaped
and bulbous Stardust (SD) tracks was performed to study the range and diversity of …

NASA's Stardust mission returned rocky material from the coma of comet 81P/Wild 2
(pronounced “Vilt 2”) to Earth for laboratory study on January 15, 2006. Comet Wild 2 …

Using chemical and petrologic evidence and modeling, we deduce that two chondrule‐like
particles named Iris and Callie, from Stardust cometary track C2052, 12, 74, formed in an …

We report the chemical and structural analysis of nine presolar silicate grains and one
presolar oxide grain from the ungrouped chondrite Acfer 094 and the CR chondrite Queen …

Abstract On April 23rd 2013 at 2: 07 am, a 1.3 kg meteorite fell in the Braunschweig suburb
Melverode (52° 13′ 32.19 ″N. 10° 31′ 11.60 ″E). Its estimated velocity was 250 km/h …

We have characterized by transmission electron microscopy the mineralogy of samples
extracted from the walls of the Stardust track 80. More than 500 fragments were studied …
