We all maybe aware a project was on for 20 years to capture a #BlackHole and we were near to that when astronomers captured the orbits of Stars around our parent super massive #BlackHole around #Sagittarius-A Star on the constellation of #Sagittarius.
They had captured the movement of stars around that Black Hole but were unable to capture the actual black hole.
Until now Astronomers were able to capture only the superficial evidence of Black Holes like #PlasmaJets etc.
Plasma Jets or Relativistic jets or Astrophysical jet is an astronomical phenomenon where outflows of ionised matter are emitted as an extended beam along the axis of rotation.[1] When this greatly accelerated matter in the beam approaches the speed of light, astrophysical jets become relativistic jets as they show effects from special relativity.
The formation and powering of astrophysical jets are highly complex phenomena that are associated with many types of high-energy astronomical sources. They likely arise from dynamic interactions within accretion disks, whose active processes are commonly connected with compact central objects such as black holes, neutron stars or pulsars. One explanation is that tangled magnetic fields[2] are organised to aim two diametrically opposing beams away from the central source by angles only several degrees wide (c. > 1%).Jets may also be influenced by a general relativity effect known as frame-dragging.
Most of the largest and most active jets are created by supermassive black holes (SMBH) in the centre of active galaxies such as quasars and radio galaxies or within galaxy clusters. Such jets can exceed millions of parsecs in length. Other astronomical objects that contain jets include cataclysmic variable stars, X-ray binaries and gamma-ray bursts (GRB). Others are associated with star forming regions including T Tauri stars and Herbig–Haro objects, which are caused by the interaction of jets with the interstellar medium. Bipolar outflows or jets may also be associated with protostars or with evolved post-AGB stars, planetary nebulae and bipolar nebulae.
Event Horizon Telescope (EHT) project, which captured the epic imagery of the black hole's EVENT HORIZON. Totally four photos were captured, which were unveiled today at press events around the world and in a series of published papers, outline the contours of the monster black hole lurking at the heart of the elliptical galaxy M87 located in constellation of Virgo on Virgo Super Cluster.
The EHT is a consortium of more than 200 scientists who were on this global sized project for about two decades.The project is named after black hole's famed point of no return — the boundary beyond which nothing, - not even light can escape the object's intense gravitational clutches or EVENT HORIZON.
It's therefore impossible to photograph the interior of a black hole, unless you somehow manage to get in there yourself. (You and your pictures couldn't make it back to the outside world, of course.)
So, the EHT images the event horizon, mapping out the black hole's dark silhouette. (The disk of fast-moving gas swirling around and into black holes emits lots of radiation, so such silhouettes stand out.)
Chandrasekar the nephew of Sir. C V Raman on a sea.voyage in 1930s theorised the star's mass needed for becoming a black hole.
Messier 87 (also known as Virgo A or NGC 4486, generally abbreviated to M87) is a supergiant elliptical galaxy in the constellation Virgo. One of the most massive galaxies in the local Universe,[a] it has a large population of globular clusters—about 12,000 compared with the 150–200 orbiting the Milky Way—and a jet of energetic plasma that originates at the core and extends at least 1,500 parsecs (4,900 light-years), traveling at relativistic speed. It is one of the brightest radio sources in the sky, and a popular target for both amateur and professional astronomers.
