2015 01 07 W 18 + GMT Sefert galaxy M 106 / NGC 4258 , 25 Million Lt yrs away in the constellation Canes Venatici has the Super Massive Black Hole at the centre of mass of 400 Million of our sun as compared with only 4 Million sun mass the SMBH at the centre of our Milky way galaxy is !Both are active, but because of enormous mass and hence gravitational tidal forces the one in M 16 has much more appetites for materials and can drag them with more vicious force ,the swirling ins become superheated due to friction and getting torn apart to their subatomic structures resulting in much more production of EMR particularly Xrays which come out in two long jets along with some of the materials,but due to enormous gravitational pull some such come back along with fresh materials giving out the appearances of two anomalous fins or arms like structure close to the core thru which newly born stars can be seen. This is Sefert galaxy as such brightening activities make it glow compared to the whole of the galaxy. Our Milky way has also become active after years of rest and two gaseous dusty clouds G 1 and G 2 (some conjecture to be a binary star also! ) are within the accretion disk of the SMBH swirling to go in or if luck could be in their favor coming out, of course not unscathed. Recently in Sept 2013 astronomers observed sudden 400 times rise in X ray flares there ,but it appears the gas clouds are still not much in harm, speculations are that one asteroid might have become an unwilling meal could be due its utter curiosity to come near it or the presence of the magnetar which is a Neutron star with strong magnetic field could have some contribution. BUT as the Xrays were coming out deep from near the core where the G clouds would take much more time to reach if teach at all before flying away, the asteroid theory appears to be more acceptable. The magnetic field lines of G 2 that undergo changes due to continuous tidal stress and strain making them to get their magnetic lines reconfigured off and on may also have the chance to release such Xray, but as already told they are far distance apart from the happening. The SMBH at M 16 has Water vapor Mega Maser equivalent to Laser operation in Microwaves in lieu of light. And this additional activities gives the galaxy a purple color . overall the galaxy looks beautiful could be serene also unless nobody knew what sinister might be going inside Idea input Lana Duze
