The release of gases through sublimation is the defining process of comets, but a new paper by Planetary Science Institute Research Scientist Jordan K. Steckloff and Senior Scientist Nalin H. Samarasinha says that periodic ...
FEFU scientists are developing a methodology to calculate the ratio of dust and gas in comas and tails of comets. This will reveal more about the history of the solar system and its development, as well as to understand the ...
Before NASA's Transiting Exoplanet Survey Satellite (TESS) started science operations on July 25, 2018, the planet hunter sent back a stunning sequence of serendipitous images showing the motion of a comet. Taken over the ...
On 6 August of 2014, after a decade of travelling through interplanetary space, ESA's Rosetta spacecraft arrived at its final target: Comet 67P/Churyumov-Gerasimenko (67P/C-G). The mission was the first to successfully land ...
Scientists have found that molecular oxygen around comet 67P is not produced on its surface, as some suggested, but may be from its body.
Last year's visitor from another star system—a cigar-shaped object briefly tumbling through our cosmic neck of the woods—has now been identified as a comet.
All high-resolution images and the underpinning data from Rosetta's pioneering mission at Comet 67P/Churyumov-Gerasimenko are now available in ESA's archives, with the last release including the iconic images of finding lander ...
A proposed space mission known as the Comet Astrobiology Exploration Sample Return (CAESAR) could expand the knowledge of the origin and history of the comet 67P/Churyumov–Gerasimenko. If selected by NASA, it will return ...
The atmosphere of Rosetta's comet 67P/Churyumov-Gerasimenko is far from homogeneous. In addition to sudden outbursts of gas and dust, daily recurring phenomena at sunrise can be observed. In these, evaporating gas and entrained ...
