Unveiling G82.2+5.3: An In-depth Look at a Supernova Remnant

At FreeAstroScience.com, our team is dedicated to bringing you the most intriguing celestial phenomena. Today, we delve into the exploration of G82.2+5.3, an intriguing supernova remnant (SNR), also recognized by names such as W63, CTB 88, and 2E 4355, nestled within the Cygnus constellation. G82.2+5.3's actual distance remains a subject of scientific debate, yet it's estimated to be roughly 10,500 light-years away from our home planet, Earth.

This distance projection implies that the dimensions of this remnant span an impressive 240 light-years. Chronological calculations, derived from meticulous observations, suggest an age bracket for G82.2+5.3 that ranges between 14,000 to 21,000 years. The remnant exhibits different morphologies when observed through radio and X-ray bands, leading to its classification as a mixed morphology remnant.

Our team at FreeAstroScience.com has also conducted optical observations. Despite the region's complex environment, we've detected a filamentary structure attributed to G82.2+5.3. While no compact remnant such as a black hole or neutron star has been discovered within the region, it doesn't rule out the possibility of a core-collapse supernova nature for G82.2+5.3. It's also noteworthy that the estimated ejecta mass of this remnant is around 1.4 solar masses, indicating a low-mass progenitor.

To visually represent G82.2+5.3, we have a composite optical image captured with a small telescope. The image was created using narrow-band filters focusing on the emission of ionised oxygen ([O III], blue), ionised hydrogen (Hα, green), and ionised sulphur ([S II], red), in conjunction with broadband filters (RGB). The credit for this mesmerizing image goes to Min Xie, Yizhou Zhang, tbcgeorge, & Chen Wu @ astrobin.
