Signs of complex chemistry evolution have been found. Complicated hydrocarbons may form inside thick clouds, where the interstellar grains are protected from harmful UV radiation. Even amino acids may form in this environment. Protostellar accretion disks Circumstellar disks seem to be a natural consequence of stellar formation in e.g. the Orion Nebula. The disks contain both gas and dust, and the latter is concentrated to the plane of the disk where a complex growth process leads to protoplanets.
Planets are a byproduct of stellar formation.
Extrasolar planets About 40 planets outside the solar system has been found. The technique to detect them involves the detection of the gravitational tug from the planet on the star via measurement of the stellar spectra. The method is limited to Jupiters relatively close to the star, i.e. earthlike planets cannot be detected this way. The results have shocked the community in that Jupiters are found very close to the star, and the orbits can in addition be rather eccentric. Extremophiles Life has been found in extreme environments as regards to temperature, pressure and energy supply.
