In the hostile atmosphere of the ‘galactic bulge’ on the coronary heart of our galaxy, scientists have noticed a planet so huge it may not truly be a planet.
A big worldwide crew of researchers discovered the item when knowledge acquired by NASA’s Spitzer infra-red area telescope, which was first launched in 2003.
Using a method referred to as micro-lensing, which measures distortions in gentle when a star pbades in entrance of one other, scientists have been capable of uncover the mysterious object is 22,000 gentle years away from Earth, and orbits its father or mother star roughly each three years.
Dubbed OGLE-2016-BLG-1190Lb, the item is regarded as 13 instances the dimensions of Jupiter, which is greater than 11 instances the diameter of Earth.
“We report the discovery of OGLE-2016-BLG-1190Lb, which is likely to be the first Spitzer micro-lensing 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,” the paper reads.
The huge dimension of the item has left scientists not sure whether it is a humungous planet or a failed star.
“The planet’s mbad places it right at the deuterium burning limit, i.e., the conventional boundary between ‘planets’ and ‘brown dwarfs’,” the report reads.
The mbad of a brown dwarf can vary between 13 to 90 instances the mbad of Jupiter, that means they aren’t huge sufficient to maintain the nuclear fusion which makes stars burn.
The researchers stated whereas observations have been essentially the most detailed ever for any planetary physique discovered utilizing microlensing. the information was nonetheless not sufficient to ascertain the exact full orbit of the planet.
The badysis has been submitted to the Astronomical Journal for publication.
