New Map Reveals Impressive Megastructures in Local Universe

This map shows the distribution of matter in the local Universe; it shows how matter flows, i.e. along which trajectories (thin lines) the galaxies move. Image credit: Valade et al., doi: 10.1038/s41550-024-02370-0.

The newly-developed map of the local Universe is based on the motions of 56,000 galaxies, according to a team of astrophysicists from the Leibniz Institute for Astrophysics Potsdam.

This Hubble image shows NGC 4694, a lenticular galaxy some 54 million light-years in the constellation of Virgo. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

These 3,500-year-old kefir cheese samples are among the few dairy remains preserved more than 3,000 years and were produced by the Bronze Age Xiaohe population -- a population that possesses mixed lifestyles and techniques (e.g., farming, dairy production, hunting, etc.). Also, although early Xiaohe individuals show little genetic interaction with other populations, mitochondrial DNA data suggest maternal connections with East and West Eurasians. By recovering DNA information from ancient fermented dairy remains, Liu et al. investigated the lifestyle linked to the usage of fermented dairy by the Xiaohe population and explore the co-evolution between the fermented bacteria and their hosts.
