A new Hubble Image Reveals a Shredded Star in a Nearby Galaxy - by SethLockman
The remnant’s intrigue comes not just from its brightness and powerful EM bursts, but also its asymmetry. Think of the stunning Ring Nebula, the Cat’s Eye, or the Lion Nebula. Each of these monuments to the awesome beauty of the cosmos was created by the same basic process as N49. An observer of most planetary nebulae could be forgiven for entertaining the thought of a cosmic watchmaker.
By comparison N49 looks like that watchmaker tried to flip an omelet and really messed up. Pinning down why and how the occasional stellar remnant gets so messy will help us understand stellar life cycles more completely. Composite image of DEM L 190, released in November of 2006. Optical data from Hubble was overlaid with X-ray data from the Chandra Observatory in blue and infrared data from the Spitzer Space Telescope in red. The result suggests a dense region in the Interstellar Medium around N49 may have contributed to the uneven expansion of the planetary nebula.Composite image of DEM L 190, released in May of 2010. Optical data from Hubble was overlaid with X-ray data from the Chandra Observatory in blue.
The past nineteen years have also seen great strides in noise reduction and data stretching algorithms, which when applied to the updated image reveal an unprecedented level of detail. Fun fact, technically none of this improves the image’s resolution, which is limited by WFPC2’s performance back in the day. But that’s just a technicality – there’s no arguing the new 2022 image shows significantly more detail.
What will this new photo reveal to discerning eyes? That’s the fun part. Maybe the more detailed filaments will help astronomers better model especially violent stellar deaths. In a few years this photo may help answer questions we don’t even have yet.
