Since that famous January night in 1610, when Galileo pointed his telescope at the sky and discovered the moons of Jupiter, many scientists and enthusiasts have followed his example and discovered many planets and stars whose existence is currently not confirmed. And long before Galileo, inexplicable phenomena in space puzzled thinkers and excited the minds of ordinary people. Today - in the 21st century, despite the fact that modern science has advanced far forward, many discoveries and observations have accumulated in astronomy that require new theoretical constructions for their explanation. All of them, at first glance, seem extremely complex, but, given the experience of the past, scientists are in no hurry to retreat. The next book in the series tells about the most exciting mysteries of modern astronomy.
