Thanks to the proximity and the fact that its axis of rotation points roughly in the Earth's direction, giving us a face - on - view of the developing planetary system, TW Hydrae is one of the most favorable targets for investigating planet formation.

On September 24, 2002, astronomers at the Planetary Systems and their Formation Workshop announced the preliminary confirmation of a long - suspected, Jupiter - type planetary companion within two AUs of Gamma Cephei A (see: MacDonald Observatory's Gamma Cephei and press release; Tautenburg Observatory in German; DPS session summary; Walker et al, 1992; Lawton and Wright, 1989; and Campbell et al, 1988 — more detailPlanetary Systems and their Formation Workshop announced the preliminary confirmation of a long - suspected, Jupiter - type planetary companion within two AUs of Gamma Cephei A (see: MacDonald Observatory's Gamma Cephei and press release; Tautenburg Observatory in German; DPS session summary; Walker et al, 1992; Lawton and Wright, 1989; and Campbell et al, 1988 — more detailplanetary companion within two AUs of Gamma Cephei A (see: MacDonald Observatory's Gamma Cephei and press release; Tautenburg Observatory in German; DPS session summary; Walker et al, 1992; Lawton and Wright, 1989; and Campbell et al, 1988 — more details below).

Alan P. Boss is an astrophysicist at the Carnegie Institution for Science's Department of Terrestrial magnetism and an expert on extrasolar planets and the formation of planetary systems.

Core accretion relies on the formation of a planetary core — a compact, massive object composed of refractory elements, similar to a terrestrial planet like Earth but typically more massive.

Three planetary formation experts — Kate Follette, Bruce Macintosh and Ruth Murray - Clay — joined a roundtable discussion on new ways of studying how planets form and whether they can explain the rise of our Solar System.

It is being done by the people who launched the Kepler satellite to detect small dips in the brightness of distant stars in order to detect the presence of now ~ 1000 new planets in the last several years, completely re-writing the textbooks on the parameter space of planetary atmospheres, solar system formation, etc..

A theory on why we don't see more life (much less alien civilizations) argues that life might arise easily, but go extinct within a billion years of planetary formation.
