Disco de escombros alrededor de la estrella Beta Pictoris (Hubble)

Un disco de escombros, que incluye cometas, asteroides, rocas de varios tamaños y mucho polvo, orbita la estrella beta pictoris, que está bloqueada en el centro de esta imagen de 2012 por un coronagraph a bordo del telescopio espacial Hubble. Esta es la vista de luz visible del sistema. El telescopio espacial James Webb de la NASA verá beta pictoris en la luz infrarroja, tanto utilizando sus coronagraphs como para capturar datos conocidos como espectros para permitir a los investigadores aprender significativamente más sobre el gas y el polvo en el disco de escombros, que incluye muchos cuerpos más pequeños como exocomets.

About The Data
Data Description The image was created from Hubble data from the following proposals: PI: S. Heap (Eureka Scientific and NASA/GSFC) and PI: D. Apai (University of Arizona). The science team includes: D. Apai and G. Schneider (University of Arizona), C. Grady (Eureka Scientific and NASA/GSFC), M. Wyatt (University of Cambridge), A.-M. Lagrange (CNRS, Grenoble, France), M. Kuchner and C. Stark (NASA/GSFC), and S. Lubow (STScI).
Instrument STIS
Exposure Dates 6 March 2012
About The Image
Compass Image A wide horizontal blue line appears at the center, extending almost to the edges, a debris disk seen edge-on. At the center is a black dot with irregular edges. The central star is blocked by an instrument known as a coronagraph. There is a whiter area within the blue on the right side, about half way from the star and halfway from the end of the blue region. The background of space is black.
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.
