Credit image : SPITZER TELESCOPE Smog Check for Comets: Measuring cometary CO2, CO, and particulate emissions Category: solarSystem: cometsPI: Reach, William T We propose to measure the CO2, CO, and dust emission from a sample of comets. This study is in the spirit of the A'Hearn et al. compilation of the OH, C2, and dust production rates for 85 comets, wherein the only widely accepted, physically-based taxonomic types of comets were identified. Specifically, C-chain-poor comets, which are predominantly dynamically short-period comets that formed in the Kuiper Belt, are distinct from the C-chain-rich comets that tend to be long-period comets arriving from the Oort cloud and having formed formed in the Jupiter-Saturn region. Spitzer/IRAC observations are unique in their sensitivity to CO2 and CO gas. CO and CO2 have prominent spectral bands that fall within IRAC channel 2, while dust strongly dominates IRAC channel 1. Despite being the second and third most abundant compositions of cometary ice, their high abundance in the Earth's atmosphere makes ground-based observations exceptionally difficult.

NEW IMAGE OF COMET C/2012 S1 ISON OF HUBBLE SPACE TELESCOPE

New image processed of comet C/2012 S1 ISON by J.P.Navarro Pina ( Team CIOC_ISON and Cometary Investigation Astrophysic G_FB ) , of credit original observing program: 13229 - Levay, Zolt - Space Telescope Science Institute Hubble Heritage imaging of Comet ISON , the new calculations of diameter of coma based in images of HUBBLE SPACE TELESCOPE , show Axis major 70.000 kms and axis minor 29.700 kms the original fit image have processed by Navarro Pina by software DS9 , the image of ISON's comet applied isophotes and false colour . Proposal Abstract: PI Zolt Levay (Space Telescope Science Institute) We propose a program to image Comet C/2012 S1 {ISON} in three phases with similar observations: early epoch, pre-perihelion, and post-perihelion. These observations are intended to complement other observing proposals to produce still imaging and small movies to maximize public engagement with this expected spectacular sky phenomenon.; click image for enlarge
