Astrophysicists believe that stars form from the gravitational collapse of giant clouds of gas and dust.
The vast bubbles, Ferguson says, are gas blown out by supernovas or stellar winds; the jets are being expelled by newly forming giant stars.
OBSERVATIONS of a Neptune - like exoplanet show that it has a watery atmosphere — suggesting it formed closer to its star than did the gas giants in our solar system.
The gas giants were formed by accreting gas from the protoplanetary disc that surrounded the sun.
In the prevailing theory of planet formation, called core accretion, dust grains stick together to form rocky worlds, and some of these rocky bodies then grow massive enough to attract surrounding gas, becoming gas giants like Jupiter.
HAT - P - 26b's relative lack of heavy elements may indicate that it formed closer to its star than gas giants like Neptune or Jupiter.
So the conclusion was the gas - giant cores must have formed before dissipation of the solar nebula — the gaseous circumstellar disk surrounding the young sun — which likely occurred between 1 million years and 10 million years after the solar system formed.
«Jupiter is the oldest planet of the solar system, and its solid core formed well before the solar nebula gas dissipated, consistent with the core accretion model for giant planet formation.»
If it accumulates this material quickly enough, the gaseous atmosphere may become too massive and collapse, beginning a rapid gas accretion phase forming a gas giant.
The gravity of the outer gas giants quickly drew these elements in, bloating them into their current forms: solid cores of rock and ice covered with gas.
