gas in on top of your rocky core and make something that looks like a
gas giant
planet, like Jupiter.
In its updated form, it receives e-mail requests from astronomers and automatically executes the observations, searching for

gas, it might push back astronomers» expected deadline for giant
planet formation

With their

During that decade, finding flattened disks of
gas and dust
around young stars became as routine as finding

Leftover
gas from the formation of the sun may have persisted into the era of planetary precursors, Holland and his co-authors note, so the dual capture of solar

gas would come either from a wind from the star, or from a
planet - forming disc of

Such a large temperature difference indicates that the
planet's atmosphere absorbs and re-radiates starlight so quickly that the

around it in the outer atmosphere cools off quickly — unlike Jupiter, which appears to have a relatively even temperature within planetary bands of atmospheric circulation.
Around it's a whirling cloud of residual dust and
