This has provided a good overall understanding of the formation and evolution of this planetary system, although many new discoveries are still being made.
If the young Sun was more active than today, one has to study the consequences this might have had for the development of the planetary environments, including the formation and evolution of planetary atmospheres and initial H2O inventories.
A description of the evolution of a planetary nebula begins before the ejection of the nebula itself.
Then researchers could use the detailed seismic picture of the moon's interior to understand better the evolution of a planetary body assembled from the vaporous debris of a giant impact on the still-forming Earth.
Long-term solar forcing and its consequences – which has come to be known as Space Climate – has important consequences for the formation and evolution of planetary atmospheres, the evolution of life and global climate on Earth.
To find a consensus among experts as to where cosmic dust comes from and where it goes was the primary goal of the session "Cosmic Dust: Its Formation and Evolution" at the planetary science section of Asia Oceania Geosciences Society 5th Annual Meeting (AOGS 2008) held in Busan, South Korea, between June 16 20, 2008.
The premises described here address: (1) the continuity relation between chemical evolution and Darwinian evolution, (2) the planetary sources of energies necessary for chemical evolution, (3) the necessity for planetary physicochemical complexity at the origin of life, and (4) macromolecular crowding that ensures chemical evolution of molecular recognition and cellular self-organization.
To provide the experts with an opportunity of starting collaboration, we have been organizing the session "Cosmic Dust: Its Formation and Evolution" at the planetary science section of Asia Oceania Geosciences Society AOGSS) Annual Meetings.
The scientists reached their conclusion with the help of computer models designed to simulate the evolution of a planetary system that originally lacked deuterium, a heavy form of hydrogen that is found in some water molecules.
The findings, described in two papers by different teams in the journal Nature, could offer some insight into the development of gas giants such as "hot Jupiters" and the evolution of their planetary systems.
