Propadiene Archives

A northern polar projection of Jupiter indicating the latitude and longitude ranges adopted for coaddition of individual spectra. The circumference latitude is 40◦ (planetocentric), enclosed concentric circles are spaced by 4◦ in latitude. The magenta line represents the statistical mean position of the auroral oval (Bonfond et al., 2017). Spatial bins in black represent regions that do not overlap in latitude with the auroral oval, blue and red spatial bins represents areas outside and inside the auroral oval, respectively. TEXES achieves diffraction-limited spatial resolutions of 0.7” to 1.4” over the wavelength range adopted in this study, which corresponds to a latitude-longitude footprint of 5-10◦ at 60◦N. -- astro-ph.EP

Detection Of Propadiene (CH2CCH2), Propene (C3H6) And Non-detection Of Propane (C3H8) In Jupiter’s Northern Polar Stratosphere

by Keith CowingMay 25, 2026May 25, 2026

We report the first detection of stratospheric propadiene (CH2CCH2) and propene (C3H6) at Jupiter’s mid-to-high northern latitudes using IRTF-TEXES measurements recorded on March 5-6, 2025.
