"Astronomers Discover Elusive 'Einstein Cross' in Rare Find"

Astronomers have discovered a rare "Einstein Cross" using the Dark Energy Spectroscopic Instrument (DESI) at Kitt Peak National Observatory. The lensing system, called DESI-253.2534+26.8843, consists of a foreground elliptical galaxy that magnifies four blue images of a background galaxy, forming a perfect Einstein Cross pattern. This discovery provides valuable insights into the early universe and demonstrates the capabilities of the MUSE instrument and computer modeling in studying gravitational lensing systems. The team aims to use these systems as cosmological tools and plans to search for supernovae in hundreds of gravitational lens systems to measure Hubble's constant.

"Scientists Uncover Einstein's Cross and Push the Boundaries of Space-Time"

Astronomers have discovered a stunning example of an Einstein cross, a rare phenomenon where the curvature of space-time around a massive foreground object splits the light from a more distant galaxy into four points resembling a cross. The confirmation and analysis of this gravitational lens, named DESI-253.2534+26.8843, provide valuable insights into the properties of lensed galaxies in the distant Universe. Using modeling techniques, researchers were able to calculate the magnification and effects of the lens, demonstrating a significant improvement in speed and accuracy. This discovery contributes to our understanding of the warping of space-time and the study of distant celestial objects.
