Write the difference between Quasars, pulsar and Blazar!
Answers
Answer:
In the simplest explanation, a Quasar is a supermassive black hole in a galaxy and a Pulsar is the rotating remnants of a dead star. ... A Magnetar is a powerful pulsar with a magnetic field that is many times stronger than that of a Pulsar. In terms of size, the Quasar/Blazar are the larger of the comparison group.
You have run-of-the-mill AGNs which would be labeled as quasars. If your AGN is spewing out super high energy gamma ray bursts then it is probably a blazar. Blazars and quasars are both the same thing: active galaxy nuclei. The only difference is that they are oriented at different angles.
Galaxy PSO J0309+27 is the oldest blazar ever found, and it is hiding secrets.
Although this may seem like a threat to Earth, the planet is generally not in danger from blazars since many of them are millions to billions of light-years away. ... 49+271757.31 is directly aimed at Earth with its radiation jet, the researchers were able to observe it using the Large Binocular Telescope
