Sirius is the brightest star in the night sky of earth not a galaxy
the closest galaxy to us is Andromeda.
A powerful jet emitted by a black hole can have significant effects on a nearby galaxy. It can heat up the gas in the galaxy, disrupt star formation, trigger the formation of new stars, and even expel gas from the galaxy, influencing its evolution and morphology.
Our solar system is centred round the Sun, which is our own star, while Sirius is a nearby star that is bigger and brighter than the Sun but a lot further away. Sirius can be found near the constellation of Orion, to the lower left of it when viewed from USA or Europe. It is the brightest of all the stars, but the planets Venus and Jupiter can be brighter at times.
In the 2012 movie "Supernova," a massive star in a nearby galaxy is shown to be on the verge of a supernova explosion. This event threatens nearby planets and prompts a rescue mission by a spaceship crew to save potential survivors who are stranded on a mining colony.
Nearby galaxies won't show much of a redshift, because they aren't moving away very quickly - or at all. For example, the Andromeda Galaxy, M31, is actually getting closer - and will collide with the Milky Way in about 3 billion years.
Sirius is one...

No, it's just a pattern of stars that someone once thought looked like a scorpion. If you were to move away from earth, all the constallations would look quite different.
Two nearby galaxies are Andromeda galaxy and Triangulum galaxy. Andromeda galaxy is about 2.56 million light years away from us. Triangulum galaxy is about 3 million light years away from us.

That is unrelated to age. An irregular galaxy is one that has been distored by the gravity of nearby galaxies.
Ah, friend, the brightest star in our magical Milky Way galaxy is called Sirius. Just like how every brushstroke adds beauty to a painting, Sirius shines beautifully in our night sky, a true masterpiece of the universe. Just take a moment to gaze up at the sky and feel the wonder of our dazzling cosmic home.
Just now (December), look for Sirius which is a nearby star and it has a type-A spectrum.
