Sharjah24 – Reuters: Scientists have observed an enormous planet about nine times the mass of Jupiter at a remarkably early stage of formation - describing it as still in the womb - in a discovery that challenges the current understanding of planetary formation.

The researchers used the Subaru Telescope located near the summit of an inactive Hawaiian volcano and the orbiting Hubble Space Telescope to detect and study the planet, a gas giant orbiting unusually far from its young host star. Gas giants are planets, like our solar system's largest ones Jupiter and Saturn, composed mostly of hydrogen and helium, with swirling gases surrounding a smaller solid core.

"We think it is still very early on in its 'birthing' process," said astrophysicist Thayne Currie of the Subaru Telescope and the NASA-Ames Research Center, lead author of the study published on Monday in the journal Nature Astronomy. "Evidence suggests that this is the earliest stage of formation ever observed for a gas giant."
