Even by the diverse standards of Saturn's satellites, Enceladus was an outlier. Its icy surface was as white and bright as fresh snow, and whereas the other airless moons were heavily pocked with craters, Enceladus was mantled in places with extensive plains of smooth, uncratered terrain, a clear sign of past internally driven geologic activity.

Mauna Kea from Hilo has a shapely aspect, for its top is broken into peaks, said to be the craters of extinct volcanoes, but my eyes seek the dome-like curve of Mauna Loa with far deeper interest, for it is as yet an unfinished mountain.

Without Jupiter cleaning out the early solar system, the Earth would be pock-marked with meteor collisions. We would suffer from asteroid impacts every day. CNN studios would probably be a gigantic crater it if wasn't for Jupiter.

NASA has hit a comet with an impactor, during the Deep Impact mission. The goal of that mission was to study the surface by making a crater and stirring up the surface material so it could be studied.

Neil deGrasse Tyson

For me at age 11, I had a pair of binoculars and looked up to the moon, and the moon wasn't just bigger, it was better. There were mountains and valleys and craters and shadows. And it came alive.

Alan Stern

The first mission to Mars did not expect to find craters and river valleys, and yet they did. The first mission to Jupiter didn't expect to find ocean worlds and volcano worlds, but they did.

Georgia Toffolo

I've been called pizza face and others said my skin was full of craters - it's just so horrible when people pin point something that you feel so badly about.

One of the first things I did on arriving at school was to break my left arm falling into a bomb crater.

Steven Squyres

We didn't know if the rover could climb up or down the hills of the crater.

Agnes Smedley

I feel like a person living on the brink of a volcano crater.

American Journalist

Used to describe holes shaped by large force, like blasts, not just regular digging.

Explosive Origin

Suggests a dramatic or major effect, often used metaphorically for notable changes.

Dramatic Impact

Refers specifically to hollows on moons, planets, and asteroids, implying an extraterrestrial context.

Celestial Bodies

Often associated with telescopes, space probes, and exploration.

Astronomical Observations

Specific to volcanology and refers to the distinct bowl-shaped opening at volcano tops.

Volcanic Structure

Usually found in geographic literature and travel guides, describing unique destinations.

Geographical Feature

When used as a verb, it emphasizes the action of creating a hollow, similar to the noun form.

Action Result

Verb form implies a sudden or unexpected creation of a hole or depression, not a gradual process.

Sudden Change

Used metaphorically to describe a sudden fail or breakdown, commonly in business or emotional contexts.

Metaphoric Collapse

More casual, often in spoken language and can convey disappointment or a downturn in situations.
