The current bulk composition of planets has been cast in some extent during the early history of the solar system, associated with the formation and evolution of the solar nebula. Particularly, this stage regulated the abundance and composition of volatiles absorbed by planetesimals and incorporated ...
The possible existence of heavy element isotope ratio differences between planets and chondritic meteorite parent bodies and whether they are due to incomplete mixing of distinct nucleosythetic products in the solar nebula is a major question in cosmochemistry. This study compares...
The mineral assemblages, textures, and bulk compositions of the comet CAIs are similar to nodules in fine-grained, spinel-rich inclusions (FGIs) found in primitive chondrites and like the nodules may be nebular condensates that were altered via solid-gas reactions in the solar nebula. Oxygen ...

Therefore, they offer a window into the building blocks of the solar system, the composition of the solar nebula and the origins of life. The near Earth asteroid (NEA) 101955 Bennu is of particular interest owing to its presumed organic-rich composition, potential economic resources and the ...

Further evidenceof the link between pulsars and neutronstars was found in 1968, when a pulsar was found in the middle of the Crab Nebula. The Crab Nebulais what remains of the supernova of the year 1054, and in as much as it has been theorized that neutronstars sometimes remain following...

More importantly, it might have preserved primitive material in pristine condition as well as the new forms as it passed through different evolutionary phases. Ryugu hails from the carbonaceous or C-type asteroid class and likely contains material from the nebula that gave birth to the Sun and ot...
