科学家认为,距离地球大约93光年的英仙座的一颗名为“恶魔之星”(英仙座β)天体是一对食双星,大约每3天就会出现视星等的变化。对于古希腊人而言,其标志着希腊神话女妖梅杜莎的眼睛,之所以被称为恶魔之星是因为该天体古怪的行为。我们依靠现代天文学才发现了英仙座奇怪双星的不可思议行为,然而距今3000多年前的古埃及人已经对这颗恒星颇为了解,自17世纪以来,英仙座β星的奇异光变被科学家进行系统性的观察。1783年,一位名叫约翰·古德利克的业余天文学家在与伦敦皇家学会的通信中提到了英仙座β星 Scientists believe that a celestial “Star of Demons” (Perseus beta) celestial being Perseus, about 93 light-years distant from Earth, is a binary pair of eclipsing stars, varying in apparent magnitude about every 3 days . For the ancient Greeks, it marks the Greek mythological virtue of Medusa’s eyes, the reason is called the devil’s star because of the strange behavior of the celestial body. We rely on modern astronomy to discover the weird behavior of strange double stars in Perseus, but ancient Egyptians dating back more than 3,000 years ago have understood quite well that this star has been singularly altered by Perseus Beta since the 17th century Systematic observation of scientists. In 1783, amateur astronomer John Goodleyk referred to the Beta Star of Perseus in his correspondence with the Royal Society of London
