Scientists have noticed a planet so huge it may not really be a planet – within the hostile atmosphere of the ‘galactic bulge’ on the coronary heart of our Milky Way galaxy.

The planet is considered 13 occasions the scale of Jupiter, which has left scientists not sure as to what it really is.
It was noticed utilizing ‘microlensing’, the place scientists measure distortions in mild when a star pbades in entrance of one other star, by the Optical Gravitational Lensing Experiment (OGLE) collaboration.
The planet, OGLE-2016-BLG-1190Lb is 22,000 mild years away from Earth, and orbits its dad or mum star roughly each three years.
Its enormous mbad places the item proper on the deuterium burning restrict – the standard boundary between planets and brown dwarfs.
The researchers say it’s potential it’s a brown dwarf.
Brown dwarfs are objects too huge to be a planet – however which aren’t large sufficient to maintain the nuclear fusion which makes stars burn.
The researchers write, ‘We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer microlensing planet in the galactic bulge/bar, an badignation that can be confirmed by two epochs of high-resolution imaging of the combined source-lens baseline object.’
