Explanation:
These near-infrared Hubble images of dust
surrounding young stars
offer the latest tantalizing evidence for planets
beyond our Solar System.
At left, the dark
gap seen in the dust disk is reminiscent of a similar
large gap in
Saturn's rings
believed to be sculpted by orbiting moons.
By analogy, the gap in
the dust disk of HD 141569 may be a larger scale
result of unseen orbiting planets.
At right is a relatively thin stellar dust ring
suggestive of planetary rings held in
place by orbiting moons.
On a much larger scale this ring around
the star HR 4796A could also
indicate the presence of orbiting planet-sized bodies too faint to be
directly visible.
For a distance comparison, the orbit of Neptune is drawn at the lower right
of each picture.
The overwhelmingly bright starlight at the center has
been blocked out to reveal the dim dust features.
