A “New” Planet has been revealed to us.

My question relates to the 2 pictures below.
Planet 9 is new, and is believed to be a GIANT and is IN OUR Solar System!

The picture below on the left shows us that we have been able to pick out planets that are 3,330 LIGHT YEARS away from earth by analyzing the shift in the red colour spectrum.
The Picture on the right says that we just found another planet in our solar system, which comparatively speaking should be starring us right up in our faces!  Some thing that is 5,000 times the mass of Pluto should be clear day!
SO….. exclude the fact the you have to be looking somewhere to find something….
Why is this information “slowly” trickling out to us?
Planet far away

The researchers, Konstantin Batygin and Mike Brown, discovered the planet’s existence through mathematical modeling and computer simulations but have not yet observed the object directly.
“This would be a real ninth planet,” says Brown, the Richard and Barbara Rosenberg Professor of Planetary Astronomy. “There have only been two true planets discovered since ancient times, and this would be a third. It’s a pretty substantial chunk of our solar system that’s still out there to be found, which is pretty exciting.”
Brown notes that the putative ninth planet—at 5,000 times the mass of Pluto—is sufficiently large that there should be no debate about whether it is a true planet. Unlike the class of smaller objects now known as dwarf planets, Planet Nine gravitationally dominates its neighborhood of the solar system. In fact, it dominates a region larger than any of the other known planets—a fact that Brown says makes it “the most planet-y of the planets in the whole solar system.”
How long will things be kept a secret and why?  For the most part, people are “awake”.  The notion that we are alone has vanished in the global brainwave.  Whether it affects us or not is out of our control (maybe), so why not be ready for the future.
Food for thought….
