Hubble and ALMA View of Beta Pictoris
This is a color composite image of the large, edge-on, gas-and-dust disk encircling the 20-million-year-old star Beta Pictoris. The image shows a curious asymmetry in the dust and gas distribution. This may be due to a planetary collision within the disk, which may have pulverized the bodies. The new Hubble Space Telescope Imaging Spectrograph visible-light image (shown in blue) traces the disk in closer to the star to within about 650 million miles of the star (which is inside Saturn's orbit about the Sun). Radio data from the Atacama Large Millimeter/submillimeter Array (ALMA) shows the dust (1.3 millimeter is colored green) and carbon monoxide gas (colored red).
About the Object
- R.A. PositionR.A. PositionRight ascension – analogous to longitude – is one component of an object's position.05h 47m 17.08s
- Dec. PositionDec. PositionDeclination – analogous to latitude – is one component of an object's position.-51° 3' 59.43"

- DistanceDistanceThe 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.63 light-years (19 parsecs)
