But an upcoming and still unpublished study by Kempton and Bryce Croll at the University of Toronto points more toward a hydrogen-helium atmosphere, several astronomers said.

By that logic, the terristial planets (iron-nickle) are just oversized asteroids, while the jovians (hydrogen-helium) are failed stars.

Observing neutrinos from the Sun had the potential of testing the theory that the hydrogen-helium fusion reactions are the source of the Sun's energy.

But it's probably a gas giant, a hydrogen-helium planet, with very, very crushing atmosphere, probably no solid surface.

The very gases were utterly alien -- methane and ammonia and a witch's brew of hydrocarbons, stirred in a hydrogen-helium cauldron.

Controlled by a barometer, pumps filled it with gas supplied by the breakdown of carbohydrate; heat flowed in to keep the interior less dense than the cold native hydrogen-helium which surrounded it at equal pressure.
