Beta Pictoris Disk Hides Giant Elliptical Ring System

 Beta Pictoris Disk Hides Giant Elliptical Ring System

[Left] – A NASA Hubble Space Telescope false-color, visible-light picture of one side of the edge-on dust disk around the star Beta Pictoris. Knots in the disk (marked A,B,C,D) are interpreted as rings of dust, seen edge-on.

[Right] – A still frame from a computer simulation, which shows a circumstellar dust disk highly perturbed by the gravitational pull of a bypassing star. The gray solid area represents the initial shape and size of the undisturbed disk. In the simulation, the gravity of the passing star rearranges the orbit of each particle, setting up an elliptical ring system that may have survived for the last 100,000 years since the impact occurred.

About The Object
Object Name Beta Pictoris
R.A. Position 05h 47m 17.08s
Dec. Position -51° 3' 59.45"
About The Object
Object Name A name or catalog number that astronomers use to identify an astronomical object.
Object Description The type of astronomical object.
R.A. Position Right ascension – analogous to longitude – is one component of an object's position.
Dec. Position Declination – analogous to latitude – is one component of an object's position.
Constellation One of 88 recognized regions of the celestial sphere in which the object appears.
Distance The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
Dimensions The physical size of the object or the apparent angle it subtends on the sky.
