Perseus constellation is only linked by our imagination
Every August, we look towards the constellation of Perseus to enjoy the Perseidas, a rain of stars that connects us with the sky and its history. Although it seems a coherent figure, Perseus is formed by very different stars, only aligned from our point of view. Its brightest star, Mirfak, is 590 million light years; Algol, on the other hand, is only 90 light years, closer to Earth than from Mirfak. Perseus also houses California nebula and stellar clusters. Astronomy reveals that heaven changes, that nothing is eternal, but that in that transience there is also beauty and astonishment.
