The discovery resets our understanding of how ice behaves in the frigid vastness of deep space and could influence our ...
The comet layer (the one with no stars) will overlay on the star layer. Raise the black level and make the sky dark in the comet layer so the sky values don’t add to the image but only the comet ...
Some of the water vapor sublimating from the warmer near-surface layers of Comet 67P (and, presumably, other comets as well) recondenses on the frigid surface, De Sanctis and her team said.
By 'stirring' the cometary orbits, additional material was accreted at somewhat higher speed over the next 25 million years, forming the outer layers of comets.
Ever since a Europe's Rosetta probe landed on the surface of a comet last year, scientists have been puzzled over its rubber duck shape. Either the strange shape was due to localized erosion on ...

New analysis points to comets as source of near-surface ice at the moon's south pole An analysis of debris blasted away from the moon's surface in 2009 uncovers layers of lunar—and Earth—history.
Matteo Massironi, of the University of Padova in Italy, led a team that identified more than 100 terraces on the surface of the comet, along with parallel layers of material in exposed walls and pits.
A geological survey of comet 67P/Churyumov-Gerasimenko has revealed its two halves have layers that don't line up, meaning they came together at a crawl ...
The team used models to compute the strength and direction of the gravity at the location of each layer. In one case, they modeled the comet as a single body with a center of mass close to the neck.
