Farthest galaxy from Earth has been recorded

(ORDO NEWS) — International experts from Waseda University (Japan), the University of Tsukuba, University College London and the University of Cambridge (UK) have recorded the galaxy farthest from Earth, and therefore the earliest ever observed. The findings of the work are published in the Astrophysical Journal Letters.

It was possible to detect the MACS1149-JD1 galaxy with the ALMA (Atacama Large Millimeter Array) telescope due to the “redshift” of its radiation.

This phenomenon (similar to the Doppler effect) can be seen when objects moving away from the observer emit light that appears red due to a shift towards longer wavelengths.

By studying these displacements, one can determine the “movements” within galaxies, as well as their distance from the Earth.

A two-month study revealed that MACS1149-JD1 rotates at a speed of 50 kilometers per second and has a diameter of three thousand light years. Further observations could help scientists understand how galaxies formed in the very early universe.
