The farthest galaxy from Earth has been recorded

International specialists from the University of Waseda (Japan), the University of Tsukuba, University College London and the University of Cambridge (Great Britain) recorded the most distant galaxy from Earth, and therefore the earliest ever observed. The results of the work are published in the Astrophysical Journal Letters.

The ALMA (Atacama Large Millimeter Array) telescope managed to detect the galaxy MACS1149-JD1 thanks to the “red shift” of its radiation. This phenomenon (similar to the Doppler effect) can be noticed when objects moving away from the observer emit light that appears red due to a shift towards longer wavelengths. By studying these displacements, it is possible to determine the “movements” within the galaxies, as well as their distance to 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 may help scientists understand the process of galaxy formation in the earliest Universe.

Earlier, astronomers from different countries under the guidance of scientists from Germany noticed in the gas-dust cloud of Sagittarius B2 the largest alcohol molecule in space – isopropanol.
