NASA supercomputer finds billions of comets mimicking the Milky Way's shape: 'The universe seems to like spirals!' Spirals are a repeating theme in astronomy, with arguably the most famous example of a swirling armed structure being our home galaxy, Milky Way. Now, using a powerful NASA supercomputer called "Pleiades," scientists have discovered yet another spiral structure on edge of our solar system.

The Pleiades (/ˈpliː.ədiːz, ˈpleɪ-, ˈplaɪ-/), also known as Seven Sisters & Messier 45 (M45), is an asterism of an open star cluster containing young B-type stars in the northwest of the constellation Taurus. At a distance of about 444 light-years, it"s among nearest star clusters to Earth & the nearest Messier object to Earth, being the most obvious star cluster to the naked eye in the night sky. It is also observed to house the reflection nebula NGC 1432, an HII region. Around 2330 BC it marked the vernal point.
