The nebula surrounding Aldebaran is mostly white gas and dust that takes on the star's orange-red reflection color. Unlike the Pleiades nebula, the Aldebaran nebula almost exclusively envelops the big star, making it appear even larger. But it is not a uniform haze as in the case of the M-45 nebula, they are seen as flows or veins of greater density, giving a dreamlike air to all of Aldebaran. And to the Pleiades too, of course.
The Aldebaran solar system according to my memory has 3 small planets of type Earth or "M" (of which only one is inhabited, Cyndriel) and 2 giant superplanets, one the size of Jupiter and another the size of Neptune, in distant external orbits . That is to say that the three small rocky ones are close to Aldebaran, while the first two are too close and only Cyndriel (planet number 3) is capable of being habitable. Those two are not habitable basically due to too much radiation, it happens like with Mercury there is nothing there but rocks.
The two giant superplanets instead have animal inhabitants of the type similar to those found on Jupiter, Saturn, Uranus and Neptune. They have no surface, only gas that becomes progressively denser and denser, without a defined surface. The image represents one of the Aldebaran superplanets.
