We report results from new and archival observations of the newly discovered active asteroid (248370) 2005 QN_137, which has been determined to be a likely main-belt comet based on subsequent discovery that it is recurrently near perihelion. From data analysis, we estimate g'-, r'-, i'-, z'-band absolute magnitudes for nucleus H_g=16.62+/-0.13, H_r=16.12+/-0.10, H_i=16.05+/-0.11, H_z=15.93+/-0.08, corresponding colors g'-r'=0.50+/-0.16, r'-i'=0.07+/-0.15, i'-z'=0.12+/-0.14, an equivalent...
Cometary activity may be driven by ices with very low sublimation temperatures, such as carbon monoxide ice, which can sublimate at distances well beyond 20 au. This point is emphasized the discovery of Oort cloud comet C/2014 UN$_{271}$ (Bernardinelli-Bernstein), and its observed out to $\sim$26 Through observations this comet's optical brightness behavior, we potentially discern drivers in outer solar system. We present a study Bernardinelli-Bernstein broad-band photometry taken 19-20 au...
The Rosetta Mission invited amateur astronomers to be part of a ground-based observing campaign for Comet 67P/Churyumov–Gerasimenko.  Amateurs, with greater access telescope time and wider geographical coverage, can add important temporal coverage scale observations complement those professional astronomers. They the bigger picture. This allows multi-scale analysis comet activity.This followed on from campaigns in support Halley-related Deep Impact Missions, as well...
<p>CC is now expanding to provide resources meet the needs of CfW and Welsh language. was first implemented in September 2021, shifting educational focus from content-based learning skills-based learning, giving teachers more freedom regarding contents their lessons. This brings novel complications, like difficulty preparing stimulating lessons while also including required skills. CC aims solve these problems by supplying with a variety easy-to-follow lesson plans,...
