The Antennae Galaxies have a genuinely unnerving quality that makes you pause and reevaluate the scope of things rather than being frightening. Two massive spiral galaxies with hundreds of billions of stars each are destroying each other. slowly. aggressively. Gorgeously.
And last week, Greg Meyer, an astrophotographer, spent almost twenty-one hours gathering enough light from the dark skies over Rockwood, Texas, to make that devastation visible. The outcome is one of those pictures that gives the cosmos a true sense of life.

Meyer trained his Sky-Watcher Esprit 120 telescope, which has an 840mm focal length, on the constellation Corvus while operating out of the Starfront Observatory in the Texas Hill Country. Since it is currently galaxy season in the northern hemisphere sky, he has been open about the fact that the scope is a little too short for the majority of galaxy work. But he knew it was worth the effort when he browsed Astrobin and saw reference images of the Antennae Galaxies.
“Since this is such a cool image of two galaxies, with an amazing backstory, I had to go for it,” he told Space.com. More than any specific piece of equipment, that kind of unwavering enthusiasm is often what sets exceptional astrophotography apart from the forgettable kind.
The picture depicts both tranquility and disaster. At the center of a whirling storm of interstellar gas, dust, and stars being violently thrown out of place are the two galactic cores, NGC 4038 and NGC 4039, which glow in warm amber and orange. Centuries of gravitational warfare have sculpted two long, arching tidal tails that extend outward from those cores and sweep into space in opposing directions.
The galaxies’ moniker comes from those tails. From a distance, they eerily resemble an insect’s antennae: they are delicate, reaching, and almost inquisitive. However, when viewed up close, each one is a structure composed of billions of displaced stars that span light-years.
For hundreds of millions of years, the collision has continued. It’s worth pausing to consider that. It will take hundreds of millions of years for these two galaxies to completely destroy and absorb one another, a process that started before complex animal life existed on Earth. Meyer’s capture is more of a frame from a movie that no civilization could ever watch from beginning to end than an actual event.
Unexpectedly, the merger’s gravitational chaos has caused a frenzy of star birth. According to NASA, the sweeping arms of the Antennae Galaxies are home to dense areas known as “super star clusters,” where new stars are forming at astounding rates.
As the galaxies settle into their final merged shape, the majority of those clusters—possibly 90%—will eventually scatter and dissolve. Long after the collision is over, a smaller number will remain as globular clusters. That has a somewhat melancholic quality: creation within destruction, most of it fleeting.
The amount of patience needed to create this image is difficult to ignore. Over the course of about 21 hours of total observation time, Meyer employed a number of astronomy filters to gather light data, which he then combined with PixInsight, Adobe Photoshop, and Lightroom.
This level of astrophotography requires careful calibration, weather cooperation, dark skies, and the willingness to sit with an incomplete picture for days or weeks before it becomes whole. It is more akin to scientific fieldwork than a long-lens hobby.
What the Antennae Galaxies are doing is not unique. In the larger context of the universe, galaxy collisions are perfectly normal. Smaller galaxies are frequently absorbed by larger ones, incorporating new stars into their own populations. Over the course of its existence, the Milky Way itself has devoured a number of smaller galaxies. Additionally, it is already headed for a collision with the Andromeda Galaxy, which will resemble what Meyer captured from Texas in about four billion years. To put it mildly, it’s unclear whether anything resembling human civilization exists to capture that event.
Meyer’s picture serves as a reminder that the universe functions on scales that are difficult to understand. In a model, these are not two abstract data points colliding. Over geological time, these structures—which contain billions of worlds—are ground together to create something new and formless.
Yes, the picture is beautiful, but if you allow it to, it also has some weight. The destruction of one galaxy by another is not a metaphor. It’s just what the universe does—it’s patient, unconcerned, and constantly blazing.
