Kohoutek 3-46 is a planetary nebula recorded by the Geminin North telescope. (Image credit: International Gemini Observatory/NOIRLab/NSF/ AURA. Image processing: J. Miller (International Gemini Observatory/NSF's NOIRLab), M. Rodriguez (International Gemini Observatory/NSF's NOIRLab) & & M. Zamani (NSF's NOIRLab)) What it is: Kohoutek 3-46, a planetary nebula.Where it is: 7,200 light-years remote in the constellation Cygnus.When it was shared: July 24, 2024.Why it's so unique:Death comes strongly for huge stars. As they burn through their fuel and start to cool, pressure drops and gravity takes control. A core collapse can follow, triggering an intense supernova surge.That's not how all stars end their lives. When a smaller sized star about one to 8 times the size of the sun tir...

The distorted pictures of the galaxy MRG-M0138 seen by the JWST. We see 2 of the images in the inset, and circled around is the faint light of the supernova Encore. (Image credit: NASA/ESA/CSA/ STScI/Justin Pierel (STScI)/ Andrew Newman (CIS)) 2 supernovas in a galaxy, and one that's so absolutely far that we see it as it was 10 billion years earlier, might be important in assisting expose the growth rate of deep space. This is a measurement that has actually rather developed some stress amongst the clinical neighborhood.The galaxy and the 2 supernovas were imaged by the Hubble and James Webb area telescopes. The galaxies are made noticeable by the power of gravitational lensing-- a phenomenon in which big quantities of mass, such as what's discovered in a galaxy cluster, can war...
