Tectonism and volcanism on Mercury
Mercury appears to have a tectonic framework and diastrophic history not found on other terrestrial planets explored to date (earth, Mars, and the moon). On the part of the planet viewed by Mariner
Global resurfacing of Mercury 4.0–4.1 billion years ago by heavy bombardment and volcanism
The findings suggest that persistent volcanism could have been aided by the surge of basin-scale impacts during this bombardment of Mercury, suggesting that resurfacing was global and was due to volcanism, as previously suggested.
The Origin of Planetary Impactors in the Inner Solar System
Old craters from a unique period of heavy bombardment that ended ∼3.8 billion years ago were made by asteroids that were dynamically ejected from the main asteroid belt, possibly due to the orbital migration of the giant planets.
Global Resurfacing of Venus
The impact cratering record on Venus is unique among the terrestrial planets. Fully 84% of the craters are in pristine condition, and only 12% are fractured. Remarkably, only 2.5% of the craters and
Voyager 2 at Neptune: Imaging Science Results
Voyager 2 images of Neptune reveal a windy planet characterized by bright clouds of methane ice suspended in an exceptionally clear atmosphere above a lower deck of hydrogen sulfide or ammonia ices.
Encounter with saturn: voyager 1 imaging science results.
As Voyager 1 flew through the Saturn system it returned photographs revealing many new and surprising characteristics of this complicated community of bodies, including small inner satellites that interact gravitationally with one another and with the ring particles in ways not observed elsewhere in the solar system.
A New Look at the Saturn System: The Voyager 2 Images
Within Saturn's rings, the "birth" of a spoke has been observed, and surprising azimuthal and time variability is found in the ringlet structure of the outer B ring, leading to speculations about Saturn's internal structure and about the collisional and thermal history of the rings and satellites.
Ancient oceans, ice sheets and the hydrological cycle on Mars
IN this Article in the 15 August 1991 issue, an error in the Nature office led to the omission of a line from Table 3. In addition, some corrections noted by the authors were not made before
Flood Volcanism in the Northern High Latitudes of Mercury Revealed by MESSENGER
MESSENGER observations of Mercury’s high northern latitudes reveal a contiguous area of volcanic smooth plains covering more than ~6% of the surface that were emplaced in a flood lava mode,
