Answers
Answer:
Both NGC 1427A and U are spiral galaxies with lots of dust and gas and active star-forming regions. NGC 1427A is an irregular galaxy.
Explanation:
Describe Galaxy.
Countless stars, solar systems, gas, and dust make up a galaxy. A galaxy is held together by gravity.
The Milky Way, which is the centre of our galaxy, also contains a supermassive black hole. When you gaze up at the stars in the night sky, you might see more stars in the Milky Way.
Because NGC 1427A lacks a recognisable form, it is an irregular galaxy. Because U has arms and a bulge in the centre, it is a spiral galaxy.
Even though the two galaxies never interacted, the forces of gravity cause them to look blurry or bent.
Some irregular galaxies are produced when two galaxies collide. Some of them combine to form beautiful ring galaxies, while others look more like blobs of stars and dust.
As a result, NGC 1427A is an irregular galaxy while U is a spiral galaxy. Both galaxies are active star-forming regions and contain large amounts of dust and gas.
