Planet Nebula consumed by Black Hole.

Recent discoveries have been made witnessing an event in the middle of the Milky Way galaxy, where our super massive black hole (SMBH) is consuming a planet forming cloud.  This black hole known as Sagittarius A* (also known as SgrA*) is a super massive black hole which acts as the lynchpin for the orbit of all star systems that are in our galaxy. Since the super massive black hole is so large, it influences everything in the entire galaxy. There is evidence to believe that every galaxy in the universe has a super massive black hole. 

Our SMBH removed the cloud out of its orbit stripping away disks of the cloud, which was believe to be in a ring of suns that was closely orbiting near the black hole. This cloud of ionised gas and dust will not be able to form into anything anymore since it has been absorbed into the singularity of the black hole.

This research was carried out at the Harvard-Smithsonian centre for Astrophysics in Cambridge. How the researchers were able to detect this event was by indirect evidence, the cloud that is being sucked up is being disrupted on its journey to the black hole, and this is the remnants of the star is being detected by the Very Large Telescope based in the Atacama Desert in northern Chile.

It is inferred from the data uncovered, is that the cloud is a proto-planetary disk that is surrounding a star with lower mass than most. Meaning that the star was probably a baby star making it easy for the black holes gravity and radiation to easily rip apart the cloud and then suck it into the accretion zone.
From data, the cloud is currently travelling to the black hole is an oval or elliptical formation in orbit. Soon to enter the event horizon where time itself will slow down, relative to out plane of observation, and the star will simply fade away. But before that it will take another year to travel to the black hole and more debris will be ripped apart from the sun cloud, falling into the hole.

The environment will be so intense what the friction alone from the event will even raise the temperature enough to emit even X-Rays, which will probably be able to detect on Earth.
Though not all hope is lost for the star, since most of it will fall in to the black hole, not all of it will be crushed out of existence. The disk and layers will be stripped but the inner layer of the cloud will remain. This is due to gravity of the star itself. As it will hold on more tightly to the inner layer due to massive gravitational wells in the star. This can also be inferred that even near the centre of the galaxy which has been known and cited to be a really bad place to create planets, it technically able to do so, even given regards to the super massive black hole that would be just on the horizon.
