A recent paper published in the Astrophysical Journal Letters has provided the first detailed account of the Laniakea Supercluster, a massive collection of galaxies that includes our own Milky Way. Using data from the Hubble Space Telescope, the researchers were able to map out the structure of the supercluster, which is 500 million light-years across and contains tens of thousands of galaxies. The results of the study have also shed light on the “Hubble Tension”, a disagreement between two different measurements of the universe’s expansion rate. The researchers found that Laniakea is expanding faster than the universe as a whole, which could help to explain the discrepancy between the two measurements. This discovery marks a major milestone in our understanding of the large-scale structure of the universe and will undoubtedly lead to further research in this area.
