The Highest Resolution Image of NGC 2346
Arturo Manchado (Instituto de Astrofísica de Canarias and Universidad de La Laguna, Spain) and collaborators use high-resolution images obtained with the Gemini Multi-conjugate Adaptive Optics System (GeMS) and the Gemini South Adaptive Optics Imager (GSAOI) to show filaments and instabilities in the bipolar lobes of the planetary nebula NGC 2346. While the gas distribution around the progenitor star was once toroidal, the system has evolved so only dense fragments remain. More information is available from the NOAO image release re-posted on the Gemini web page. The researchers will present complete results, including numerical modeling, in The Astrophysical Journal, and a preprint is now available.

The unprecedented resolution of GSAOI and GeMS reveals clumps of molecular hydrogen in the bipolar lobes of planetary nebula NGC 2346. This image shows H2 (1-0) S(1) emission at 2.12μm and is about 1 arcminute on a side.

Visit Gemini at IAU Exhibit Booths
Gemini will participate in two exhibit booths during the International Astronomical Union General Assembly in Honolulu, Hawai‘i, August 3–14. Visit us with the Maunakea Observatories (Booth/Pavilion 100) and with the National Science Foundation (Booth/Pavilion 212). Staff look forward to talking and meeting with users, especially during the designated breaks and poster sessions. We hope to see you there!
