           Pioneer 10 and 11 and Voyager 1 and 2 have the distinction of being the only human-made objects to have left or be on track to leave the Solar System (other than the recently launched New Horizons mission). While their scientific work is significant, the history of these four missions reveals a deeper cultural legacy. One of the primary public faces of these missions was science communicator Carl Sagan. By exploring how Sagan defined the significance of these missions in his work, we reveal the impact of these missions on our collective imaginings of spaceflight and space exploration (i.e. “astroculture”). We find that the twin Pioneers and Voyagers inspired self-reflexive ideas of human isolation and fragility within the cosmos, introduced communication with extraterrestrials as a serious aspect of spaceflight efforts, and supplemented the image of the astronaut with the robotic probe as the symbol of the human spirit of exploration.

AbstractThe dynamical interrelation between resonant trans-Neptunian objects and short-period comets is studied. Initial orbits of resonant objects are based on computations in the model of the outward transport of objects during Neptune's migration in the early history of the outer Solar system. The dynamical evolution of this population is investigated for 4.5 Gyr, using a symplectic integrator. Our calculations show that resonant trans-Neptunian objects give a substantial contribution to the planetary region. We have estimated that the relative fraction of objects captured per year from the 2/3 resonance to Jupiter-family orbits with perihelion distances q<2.5 AU is 0.4×10−10 near the present epoch.

The article provides extensive information on the formation, evolution and structure of the solar system. It also discusses the planets of the solar system and the dwarf planets. Its noted that the Kuiper objects are the celestial bodies which belongs to the solar system. NASA's New Horizons spacecraft is currently helps studying four objects in the Kuiper belt. There is also talked about TTauri type stars. The article discusses the future transformation of the Sun from a Red Giant to a White Dwarf. Key words: Kuiper Belt, T Tauri Star, Dwarf Planets, Planet X
