What is a BL Lac object?
A BL Lac object is a term used in astronomy for a type of active galaxy with an active galactic nucleus.
Does the Milky Way Galaxy have an active galactic nucleus?
Our Milky Way has a supermassive black hole at its nucleus. It is an active radio source. It is probably not a Seyfert galaxy, which is a galaxy of a type characterized by a bright compact core that shows strong infrared emission, though.
What do active galaxies differ from normal galaxies?
Galaxies that emit much more radiation (different types of radiation) than a typical galaxy. This actually happens in the galaxy's center, so it's more accurate to talk about an active galactic nucleus. The active galactic nucleus is believed to be caused by a black hole. From Wikipedia: " The radiation from AGN is believed to be a result of accretion of mass by a supermassive black hole at the centre of its host galaxy."
Is your galaxy an active galactic nuclei?
No.
What is AGN?
An AGN is an active galactic nucleus, a compact region at the centre of a galaxy with a much higher than normal luminosity over some portion, possibly all, of the electromagnetic spectrum.
What is an AGN?

What is AGB slot?
An AGB (Active Galactic Nucleus) slot refers to a specific range in the luminosity or energy output of galaxies that host active galactic nuclei, where the activity of supermassive black holes is particularly pronounced. In this context, "slot" can denote a range of parameters, such as black hole mass or accretion rates, that correlate with the observable properties of the AGN. This concept is crucial for understanding the relationship between black hole growth and galaxy evolution.
How long does it take the sun to complete one orbit around the galactic nucleus?
Astronomers tell us between 225,000 and 250,000 years.
Is Betelgeuse a quasar?
No, Betelgeuse is not a quasar. Betelgeuse is a red supergiant star located in the constellation of Orion, while a quasar is a highly energetic and distant active galactic nucleus powered by a supermassive black hole at the center of a galaxy.
What controls the movement in and out of the nucleus?
Active transport
How far does the sun lie from the milky way's nucleus?
The sun is 30'000 light years from the central galactic point.
A quasar is a type of?
A type of galaxy is probably the answer you are looking for. However, a quasar is actually an active galactic nucleus.
