  Ganymede
Craters with such a 'central pit' are common across Ganymede and are especially intriguing since they may reveal secrets about the structure of the satellite's shallow subsurface.
The two craters in the center of the image lie in the ancient dark terrain of Marius Regio, at 40 degrees latitude and 201 degrees longitude, at the border of a region of bright grooved terrain known as Byblus Sulcus (the eastern portion of which is visible on the left of this image).
The craters are situated in a region of bright grooved terrain named Byblus Sulcus, located in the northern part of Marius Regio at 39 degrees latitude and 201 degrees longitude.

Crater densities are generally lower on the light terrain than on the dark, consistent with direct stratigraphic indications that the light terrain is younger.
However, the highest crater densities on the dark terrain are only about one-third the density of a similar population of craters on neighboring Callisto, even though both satellites should have had virtually identical cratering histories.
CRATER AND PALIMPSEST MATERIALS Impact landforms on Ganymede exhibit a broader range of morphologies than is found on the terrestrial planets, although the most abundant crater forms on Ganymede are similar to those of the terrestrial planets.

 Brief Extra 2-25-04 / The founders would be pleased: Nicholson construction begins in May
Nicholson Hall, known in U facilities language as Building 5, stands at the corner of Pillsbury Drive and Pleasant Street.
In 1914, when chemistry moved to the first building on the new mall that spread to the south, a remodeled Nicholson become the men's union; the women's union was nearby, in Shevlin.
Losing Nicholson, though, would have meant breaking up of the set of historic buildings around Pillsbury drive, and contending with the specter of Northrop's giant back side.

 Universe Today - Nicholson Crater on Mars
Large craters often have this kind of central peak, which forms when material rebounds after a meteor impact, but Nicholson Crater's peak is heavily eroded by wind and water.
Located in the centre of this crater is a raised feature, about 55 kilometres long and 37 kilometres wide, which extends to a maximum height of roughly 3.5 kilometres above the floor of the crater.
The tall feature in the centre of this hill is the central peak of the crater, which forms when the surface material ‘rebounds’ after being compressed during the formation of an impact crater.

Their preliminary work suggests that this original crater was nearly as large as the Chicxulub crater, which caused the KT extinction 65 million years ago.
However, the discovery of the actual Chicxulub crater was key to wide acceptance of the reality of the impact catastrophe 65 million years ago.
An impact crater believed to be associated with the "Great Dying," the largest extinction event in the history of life on Earth, appears to be buried off the coast of Australia.

 6,500 feet up and 16 feet deep
Crater Lake National Park employee Phil Kelley, above, ascends a stairway from a deep snowpack to his second-floor office at the park's headquarters complex.
Though the park historian was holding his tongue firmly in cheek while talking about the 1980 flick, which features a snowed-in Jack Nicholson slowly going mad at an isolated mountain resort, his point is well taken.
Indeed, the crater rim, a little more than 500 feet above the headquarters, is frozen in arctic weather for the winter.

Nicholson was a graduate student at the University of California at the time, and computed the orbit of his discovery for his Ph.D. dissertation.
Nicholson computed the orbits of several comets and of Pluto, and for decades produced annual reports on sunspot activity and magnetism from his observations with the 150-foot Solar Tower Telescope.
In the early 1920's, Seth Nicholson and Edison Pettit used a vacuum thermocouple to measure the temperatures of the Moon, planets, sunspots, and stars.

On the left is a crater that has been torn apart by tectonic forces.
The pair of oblong craters on the right was formed by the impact of a gravitationally bound pair of asteroids or a split comet.
The oblong shapes of the craters suggest that the impactors struck the surface at a shallow angle.

The European Space Agency’s (ESA) Mars Express snapped this image of Nicholson Crater, located at the southern edge of Amazonis Planitia on Mars, north-west of a region called Medusae Fossae.
Using the High Resolution Stereo Camera (HRSC) onboard the ESA orbiter, scientists are trying to evaluate how the crater’s central feature was shaped and what kind of processes led to it formation.
The tall feature in the center of this hill is the central peak of the crater, which forms when the surface material ‘rebounds’ after being compressed during the formation of an impact crater.
