Estas son imágenes del telescopio espacial Hubble de cuatro discos protoplanetarios alrededor de estrellas jóvenes en la Nebulosa de Orión, a aproximadamente 1.300 años luz de distancia. Los discos varían en tamaño de dos a ocho veces el diámetro de nuestro sistema solar. Los astrónomos vieron los discos en imágenes de encuestas a gran escala de la nebulosa Orion tomadas con Hubble entre enero de 1994 y marzo de 1995.

| 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. |
