Скачать или смотреть The Shape of Scorpius in Three Dimensions

This visualization reveals the stars of the Scorpius constellation in three dimensions. Watch as the familiar pattern on the sky distorts into a whole new perspective.

The opening of the sequence pans up to Scorpius in the night sky. The brightest star in the constellation, Antares, is a red supergiant known as the "heart of the Scorpion". The name "Antares" can be translated to "rival of Ares" (i.e., "rival of Mars") due to its resemblance to the red planet in the night sky. The bright stars forming the tail of the scorpion are also referred to as the "fish hook". At the end of the tail, next to the star Fuyue, is the star cluster known as Ptolemy's Cluster (Messier 7). To its lower left the famous asterism known as "the teapot" from the constellation Sagittarius can be found.

As the camera orbits around the constellation, the stars of the scorpion and the dark dust clouds in the disk of our Milky Way Galaxy reveal their true distributions in space. The most distant star of the constellation is Apollyon (Iota-1 Scorpii), a supergiant that is around 2,000 ly away and over 35,000 times more luminous than the Sun. Toward the end of the spin, several star clusters cross the view of the camera. The most populated one is the Wishing Well Cluster (NGC 3532) from the constellation Carina at around 1,300 ly from the Sun. The Hyades cluster, our nearest open cluster at just 150 ly in Taurus, makes an appearance at the lower left of the camera view just before the return to the Solar System.

This visualization features over 11 million stars down to a magnitude of 13.5 across the sky. The positions, colors, and luminosities are based on the Gaia and Hipparcos star catalogs, complemented by the HYG Database, which includes data from the Yale and Gliese catalogs. Insterstellar dust is visualized using data from the Edenhofer et al map out to a distance of 1.25 kiloparsecs (~4,000 ly) from the Sun and from the Lallement et al data out to 3 kiloparsecs (~9,800 ly). The rest of the Milky Way plane is recreated using simulated spiral galaxy data for stars and dust from the Horizon GalMer database.
