Giant 'planet' found at the galaxy's center

A mysterious world 4,000 times more massive than the Earth has been found lurking 22,000 light years away.
Discovered by an international team of astronomers using data from NASA's Spitzer infra-red space telescope, the uninspiringly-dubbed OGLE-2016-BLG-1190Lb is so large that scientists are still debating over whether it is actually a planet or a star.

It was found through a Polish astronomical collaboration known as the Optical Gravitational Lensing Experiment (Ogle) which looks for distant planets by observing stars passing in front of other stars.
When this happens, the gravity of the foreground star can focus the light of the background star, making it appear brighter and helping to highlight the presence of any orbiting worlds.

"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 assignation that can be confirmed by two epochs of high-resolution imaging of the combined source-lens baseline object," the researchers wrote.

"The planet's mass places it right at the deuterium burning limit, i.e., the conventional boundary between 'planets' and 'brown dwarfs'".

the are different that' why we are 2/3 the way out and in the last 15% of mass, wtf?

But you dont understand the 15% value. Again, distance and mass are 2 different thinks.

grimsituation6, you are making a total fool of yourself. You don't know what you are talking about but are arguing with someone that does. No one is saying we are in the middle. Not being in the middle does NOT necessarily mean being on the edge. The solar system is not in the middle of the galaxy NOR is it at the edge. Is that really so difficult tom understand. You lacxk understanding of some VERY basic concepts, including some basic word definitions. Here they are to help you Source: oxforddictionaries,com Source: oxforddictionaries,com Even with your false claim that the solar system:   it... [More]

I would love to hear how you came up with that number. If I was cynical man I would think that you made it up, but you wouldn't make something like that up would you ?

The Milkyway have a radius of between 50.000 and 90.000 light years and the Earth is 26.000 light years from the center. If the radius is in the lower end we are pretty much exactly halfway from the center, if the higher value is right we are actually much nearer the center than the edge. Thats the numbers, make of them what you want, but don't call people idiots for pointing out the facts to you grimsituation6.

Sooo... Are we in suburbs, or downtown?

like many topics, has the potential for some interesting discussion....then people post! how can we even begin sensible discussions on some of these posts...   let me try...   I think its nearer 99.8% rather than 99.9% probable that flying pink elephants exist on a planet and they are the only life form there...   (sarcasm by the way...just in case)

Nope, its 97.75%.
