US EditionAstronomers Discover ‘Fossil Galaxy’ 3 Billion Light-Years Away
CHILE, JUL 06 – The CRISTAL survey using ALMA reveals scattered star formation and early disk structures in galaxies formed one billion years after the Big Bang, refining galaxy evolution models.
- Using advanced telescopes in Chile and Arizona, astronomers identified the fossil galaxy known as KiDS J0842+0059, located approximately three billion light-years away from our planet.
- In 2018, astronomers first detected KiDS J0842+0059 using the VLT Survey Telescope, identifying it as a galaxy that has remained mostly unchanged for the past 7 billion years.
- This fossil galaxy joins a few others like NGC 1277, confirmed by the Hubble Telescope in 2018, providing new insights into early massive galaxy formation phases.
- Professor Cappellari noted fossil galaxies are a direct link to massive galaxy populations from billions of years ago with star formation that was "quick and violent."
- This discovery supports studying galaxy evolution and complements upcoming observatories like the Simons Observatory to explore the cosmos in greater detail.

Scientists discover surprising star birth patterns in ancient galaxies
Astronomers are now getting an unprecedented look at what galaxies looked like when the Universe was still in its infancy. Thanks to a new study using the powerful Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers have captured stunning details of galaxies that formed just one billion years after the Big Bang. This period marks […] The post Scientists discover surprising star birth patterns in ancient galaxies appeared fi…
