  "account": "The Summer Triangle, a striking constellation visible in the Northern Hemisphere during summer, features three bright stars from different constellations. At its center is Deneb, the brightest and northeasternmost star, whose name means \"tail\" in Arabic. Deneb marks the tail of Cygnus, the swan constellation, which appears as a majestic bird when viewed in the night sky.\n\nCygnus' wings, outlined by a rectangular box in illustrations, extend from the line connecting Deneb and Albireo, also known as the \"beak star.\" The swan's neck stretches along the band of the Milky Way, and binoculars can reveal many stars along this path, including the Messier 29 open cluster located south of the swan's torso.\n\nA telescope or strong binoculars can unveil the Cygnus Loop, a supernova remnant also called the Veil Nebula. This gassy remnant of a large dying star appears as a faint ring about three degrees across, about six times the diameter of the Moon. The high-energy X-ray source Cygnus X-1, first detected in 1971, is a black hole about 6,070 light years away, spinning at a rate of more than 800 times per second. Despite its proximity, Cygnus X-1 poses no threat to Earth and offers a unique opportunity to study the universe.",
  "summary": "Bird constellations abound in the night sky, including Cygnus, the majestic swan. Easy to find with its dazzling stars, it is one of the few constellations that look like its namesake, and it is full of treasures. Visible in the Northern Hemisphere all summer long, there’s so much to see and even some things that […]",
