This is the first image of Sagittarius A* the supermassive black hole at the center of our galaxy. This is the first direct visual evidence of the presence of this black hole. Until now, it has been recognized for its influence on the stars close to it. The black hole was imaged using the Event Horizon Telescope (EHT), an array that joined together eight existing radio observatories around Earth to create one virtual "Earth-sized" telescope. The telescope is named after the event horizon, a nickname for the boundary of the black hole beyond which no light can escape. It took five years to process the image. Credit: EHT Partnership

Improving the ability to observe the black hole at the center of the galaxy will make it possible to test Einstein's theory of general relativity

Says Dr. Shahar Hadar, a theoretical astrophysicist from the University of Haifa and Oranim College who also works in the development of the next generation of the Event Horizon Telescope. He also explains why it took five years to produce the photo published this week and what is planned to be done in order to improve the resolution

Schematic diagram of the bacterial operon (top) versus the eukaryotic transferron (bottom). According to the researchers, instead of "beads on a string" a kind of genetic "stroke-na" game developed during evolution that allows using the same "letters" - that is, messenger RNA molecules originating from genes located on different chromosomes - to create different "words", i.e. different transferrons

How did evolution overcome the lack of order in the storage of genetic information in the transition from bacteria to more developed creatures?
