There are some things that never cease to amaze me and the discovery of distant objects is one of them. The James Webb Space Telescope has just found the most distant galaxy ever observed! It has the catchy title JADES-GS-z14-0 and it has a redshift of 14.32. This means its light left when the Universe … Continue reading "Webb Finds the Farthest Galaxy Ever Seen (So Far)"
#Physicists solve puzzle about #ancientgalaxy found by #Webbtelescope
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because JWST-ER1g acts as a lens and bends light from a distant source, which then appears as a ring—a phenomenon called strong gravitational lensing, predicted in Einstein's theory of general relativity.
'Beyond what's possible': New #JWST observations unearth mysterious #ancientgalaxy
Our understanding of how galaxies form and the nature of dark matter could be completely upended after new observations of a stellar population bigger than the Milky Way from more than 11 billion years ago that should not exist.
For the first time, #astronomers have observed #chaos in the center of an #ancientgalaxy, the sort of place where a million or more #stars are locked in a dance of death.
#InternationalGeminiObservatory traces #gammarayburst to nucleus of #ancientgalaxy, suggesting #stars can undergo demolition-derby-like collisions
Astronomers studying a powerful gamma-ray burst (GRB) with the Gemini South telescope, operated by NSF’s NOIRLab, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy.
