Description

Our publication is an image of Abell 194 the galaxy cluster, which includes Arp 308 (NGC 545 + NGC 547) and the Minkowski object (in the halo of NGC 541) as well as other surrounding galaxies. This rich group includes 10 galaxies from the New General Catalog (NGC) that are identified in the flyby image, as well as several dozen other galaxies visible in this field. Despite its impressive distance of about 250 million light-years, several of the brightest galaxies in the cluster can be seen in amateur telescopes.Of particular interest is the particular dwarf galaxy close to NGC 541 ARP 133 and has been the subject of fairly detailed studies. The jet of matter from the central black hole of NGC 541 reaches this galaxy and is the cause of a burst of star formation. This rather rare type of star nursery is known as the Minkowski object, an example of a black hole creating life in the universe in the form of baby stars.There is also the unusual feature known as the Minkowski object, which appears as a small blue spot on the edge of the galaxy NGC 541. This galaxy is a powerful transmitter of radio waves, and images in other wavelengths show a large jet extending from the center of the galaxy to the Minkowski object. Astronomers have discovered that the Minkowski object is a region of intense star formation. An abundance of warm blue-white stars gives the object its distinctive color.NGC 541 is a lenticular galaxy. It is located in the constellation Whale about 242 million light-years from the Milky Way.  NGC 541 is part of the group of NGC 545, the largest and brightest galaxy in this group9. The NGC 545 group is part of a larger group, the galactic cluster Abell 19410,11.The 2 galaxies in this group, NGC 545 and NGC 547, produce huge and powerful jets of matter in the region surrounding their central supermassive black hole 12. These jets were picked up in radio waves by the VLA's radio telescopes. The jets of these two gravitationally interacting galaxies are projected at distances of about 250,000 light-years.12 The shorter jet of the galaxy NGC 541, a little lower on the right, collides with a dark blue colored hydrogen cloud that was also detected in radio wave by the VLA.The shock wave created by this jet generated a star-forming zone, colored pale blue. This rather rare type of star nursery is known as the Minkowski object,13,12, an example of a black hole creating life in the universe in the form of baby stars.The object, a particular star-forming galaxy, is clearly visible in full-resolution view and undergoes a large burst in star formation. The burst is believed to have been initiated by a radio jet emerging from the core of NGC 541. This jet-induced star-forming phenomenon has also been observed in other objects such as Centaurus A. This object is named after the German astronomer Rudolph Minkowski, who discovered it in 1958.Based on the internal velocity of the galaxy measured by the Hubble Space Telescope, the mass of the supermassive black hole at the center of the galaxy NGC 541 would be between 190 and 920 millions. Many other fascinating galaxies, galaxy clusters and quasars are visible in the image. The faint galaxy cluster just below the center of the image is about 5 billion light-years away.
