A team of astronomers became a crew of cosmic crash scene investigators while studying wreckage left behind by two galaxies that smashed into one another over 1 billion years ago.

The scientists used the Gemini South Telescope to investigate the twisted galactic disk of the galaxy NGC 4753, located around 60 million light-years from Earth, seeing it in more detail than ever before. The team paid particular attention to a complex network of dust tracks that appear to twist around the heart, or galactic nucleus, of NGC 4753.

Galaxies come in four main shapes: Lenticular, elliptical, irregular and spiral, like the Milky Way. While NGC 4753 is classified as a lenticular galaxy, however, the merger with a smaller dwarf galaxy 1.3 billion years ago has left its disk of stars and dust with a twisted shape that fits it into the aptly named subclass of “peculiar” galaxies. 

“Galaxies that gobble up another galaxy often look like train wrecks, and this is a train-wreck galaxy,” Tom Steiman-Cameron, team leader and a senior research scientist at Indiana University, said in a statement.

NGC 4753 was first discovered by German-British astronomer William Herschel in 1784; it’s located in the constellation of Virgo. The galaxy is situated in the NGC 4753 Group of galaxies which, in turn, is part of the Virgo II cloud of 100 galaxy clusters that sits on the southern edge of the Virgo supercluster of galaxies.

The twisted dust lanes of NGC 4753 have long been a source of fascination for astronomers. In 1992, a team of scientists, also led by Steiman-Cameron, determined that this mystifying feature is the result of a lenticular galaxy colliding with a gas-rich dwarf galaxy. 

Such a collision would have injected the lenticular galaxy with a massive amount of gas, triggering bouts of intense star formation called “starbursts” and filling NGC 4753 with vast amounts of dust. 

As the dwarf galaxy mixed into the larger lenticular galaxy with its stars spiraling toward its galactic center, the accumulated dust spread would’ve spread out into a disk-like structure.

A fascinating phenomenon called “differential precession,” caused by the angle at which the two galaxies collided, would have then taken over to wind the dust into a more intriguing shape.

The easier way to picture precession is to think of a child’s spinning top. Imagine what it would look like if you set it spinning, then viewed it aerially. As the top slows and loses momentum, the top of the top — for lack of a better word — would start to wobble, and its angle of orientation would changes. That’s a simple precession analog.

The precession experienced by NGC 4753 is called “differential” because it varied across the galaxy according to its distance from the galactic nucleus. It would’ve been faster at the heart of the galaxy and slower at its edges. This galactic wobble, scientists say, had twisted up the dust into the twirling lanes we see today.

“For a long time, nobody knew what to make of this peculiar galaxy,” Steiman-Cameron said. “But by starting with the idea of accreted material smeared out into a disk and then analyzing the three-dimensional geometry, the mystery was solved. It’s now incredibly exciting to see this highly-detailed image by Gemini South 30 years later.”

Steiman-Cameron also points out that, though the trainwreck galaxy NGC 4753 appears to be unique, this may be the result of the angle at which astronomers view it from Earth. He added that if this peculiar lenticular galaxy was viewed from above, it would likely appear like any other spiral galaxy.

This means that the incredible and fascinating features may not be rare so to speak, but merely accessible to us thanks to our unique edge-on perspective from Earth.
