Detected in 2017 and observable for only a few weeks, the first known interstellar object to pass through the solar system confounded astronomers, sparking speculation it could be a giant snowflake, h...
Comet 67P/Churyomov-Gerasimenko – arguably the most-studied comet in history – has yielded a cosmic surprise: It emits molecular oxygen drawn from its nucleus.
In early July, Comet NEOWISE approached the sun for the first time in nearly 4,500 years. For observers in the Northern Hemisphere, it is now faintly visible toward the Northwest after sunset. When vi...
ALMA reveals unusual composition of interstellar comet 2I/Borisov.
Scientists pursue research through observation, experimentation and modeling. They strive for all of these pieces to fit together, but sometimes finding the unexpected is even more exciting.That’s...
The San Diego Supercomputer Center (SDSC) at the University of California, San Diego this week formally launched "Comet," a new petascale supercomputer designed to transform scientific research by exp...
On 4 July 2005 at 5:52 UT the Deep Impact mission successfully completed its goal to hit the nucleus of 9P/Tempel 1 with an impactor, forming a crater on the nucleus and ejecting material into the com...
We conducted shock experiments simulating comet impacts to assess the feasibility of peptide synthesis by such a process. We used frozen mixture of the amino acid glycine, water ice, and silicate (fo...
ANN ARBOR—A comet-bound spacecraft that spent more than two years in a deep sleep mode woke up on Jan. 20 to begin the home stretch of its decade-long journey to a mile-wide ball of rock, dust and ice...
steroid (596) Scheila was reported to exhibit a cometary appearance and an increase in brightness on UT 2010 December 10.4. We used the IRCS spectrograph on the 8-m Subaru telescope to obtain medium-r...
We report results based on mid-infrared photometry of comet 103P/Hartley 2 taken during May 4-13, 2010 (when the comet was at a heliocentric distance of 2.3 AU, and an observer distance of 2.0 AU) by ...
We have used the Spitzer Space Telescope Infrared Spectrograph (IRS) to observe the 5-37 micron thermal emission of comet 73P/Schwassmann-Wachmann 3 (SW3), components B and C. We obtained low spectral...
