![]() Saurabh Jha/ESA/Hubble/NASAĪlbert Einstein first considered the idea of gravitational lensing when he was developing his theory of general relativity in 1912. Researchers have used this near-complete Einstein ring to study the properties of the galaxy as it existed 9.4 billion years ago. "In particular, Hubble helped us to identify the four duplicated images and the stellar clumps of the lensed galaxy."Īn Einstein ring image of GAL-CLUS-022058 captured by Hubble in 2020. "Such a model could only be obtained with the Hubble imaging," Díaz-Sánchez said in a press release. To measure the physical qualities of GAL-CLUS-022058 and better understand conditions during this period of rapid star birth, the team-led by Polytechnic University of Cartagena astronomer Anastasio Díaz-Sánchez-examined the images of the galaxy created by gravitational lensing. "This will help us to better understand star formation in distant galaxies using planned observations." Susana Iglesias-Groth of the Institute of Astrophysics of the Canary Islands in Spain said in a press release from the European Space Agency (ESA): "We can clearly see the spiral arms and the central bulge of the galaxy in the Hubble images. ![]() This rapid rate of star formation could explain why there are so many galaxies with an elliptical shape in the Universe, according to researchers. The galaxy existed during a period of the Universe that is marked by intense star formation, with stars being born at a rate of thousands of times faster in bright and dusty galaxies than we see in the Universe today. This name is a nod to both its appearance as a glowing ring and its home constellation Fornax, or "the furnace," located in the sky over the southern hemisphere.
