Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Exploring the Antennae." The Antennae Galaxies (NGC 4038 4039) are located in the constellation Corvus about 45 million light years from Earth. They were discovered by William Herschel in 1785. NGC 4038 and NGC 4039 are passing through each other at a very high speed, at hundreds of kilometres per second. The reason why the galactic merger is taking hundreds of millions of years to complete is the enormous size of the galaxies.
The tidal (from gravity) tails that have earned them the name Antennae were formed 200 to 300 million years ago, during the galaxies’ first encounter. As NGC 4038 and 4039 collided and passed through each other, some of their stars, dust and gas were drawn out into long tails of material. The two streamers will eventually either fall back into the newly formed elliptical galaxy or be lost to space.

Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Saturday, March 27, 2021 entitled "Exploring the Antennae."

The description is tongue-in-cheek of a supposed collision 60 million years ago :-)
Of course a two-dimensional image can be deceptive :-)
If two galaxies actually collided that would have been God's will.
APOD Background
"Explanation: Some 60 million light-years away in the southerly constellation Corvus, two large galaxies are colliding. Stars in the two galaxies, cataloged as NGC 4038 and NGC 4039, very rarely collide in the course of the ponderous cataclysm that lasts for hundreds of millions of years. But the galaxies' large clouds of molecular gas and dust often do, triggering furious episodes of star formationi near the center of the cosmic wreckage. Spanning over 500 thousand light-years, this stunning view also reveals new star clusters and matter flung far from the scene of the accident by gravitational tidal forces. The remarkably sharp ground-based image includes narrowband data that highlights the characteristic red glow of atomic hydrogen gas in star-forming regions. The suggestive overall visual appearance of the extended arcing structures gives the galaxy pair its popular name - The Antennae."
