..."“So you have a nice, normal spiral galaxy, right, just out there doing its thing, when BAM! A smaller galaxy careens right through the middle of it like a bullet! Chaos, fireworks, explosions everywhere! And then, after the second galaxy leaves, the first one starts changing shape, transforming, into a big ring, and then stars start dying, and now there’s this huge ring a gazillion miles across that’s just littered with black holes and other weird objects sucking down matter and spewing out death rays!”" ...

..."That’s why AM 0644 looks blue! When clouds form stars, many of them are massive and hot, so they shine blue. Also, they don’t live long; these massive stars go through their fuel in a million or tens of millions of years. When that happens they explode, leaving behind either an extremely dense ball called a neutron star or a black hole."

Thank you for sharing the article about the galactic collision that created a ring of black holes and neutron stars. I find this topic very intriguing and would like to provide some additional insights.

Firstly, it is important to note that galactic collisions are not uncommon in the universe. In fact, they have been happening since the early days of the universe and continue to occur even today. However, the collision between the two galaxies in this article is particularly interesting because of the resulting ring structure and the formation of black holes and neutron stars.

Based on our understanding of galactic collisions, it is likely that the two galaxies involved were not evenly matched in terms of size and mass. This is because a smaller galaxy would not have enough gravitational pull to significantly affect the larger galaxy. Instead, it would pass through the larger galaxy, causing a disturbance in its shape and structure.

The formation of the ring structure is a result of the gravitational forces between the two galaxies. As they pass through each other, the gravitational pull of the smaller galaxy would cause the stars in the larger galaxy to be pulled towards it. This creates a ripple effect, causing the stars to move in a circular motion and eventually forming the ring structure.

In terms of the blue color observed in AM 0644, it is true that the formation of massive stars can contribute to this color. However, it is also important to note that the collision itself would have triggered a burst of star formation in the larger galaxy. This would result in the formation of new stars, including massive and hot ones that emit blue light.

Lastly, the death of these massive stars and the formation of black holes and neutron stars is a common occurrence in the universe. However, the collision between the two galaxies in this article would have accelerated this process, resulting in a higher concentration of these objects in the ring structure.

In conclusion, the galactic collision described in the article is a fascinating event that provides us with a unique opportunity to study the effects of such collisions on the structure and evolution of galaxies. I am excited to see what further discoveries and insights we can gain from studying this phenomenon.
