What the Viral Samsung Galaxy S23 Ultra 100x Zoom UFO Video Really Shows

In late December 2023, a short video taken with a Samsung Galaxy S23 Ultra went viral after a user zoomed in at 100x on a shiny, disc-shaped object drifting through a clear blue sky. Viewers called it a UFO, a “biblically accurate angel,” and every imaginable meme in between. What it actually is matters a lot less than what the clip revealed about the S23 Ultra’s camera — and, more importantly, the limits of Samsung’s 100x Space Zoom.

What the video actually shows

The footage, originally posted by X user @Alphafox78 on December 30, 2023, captures a small, silver, spoked object hanging motionless against a cloudless sky. The clip cuts between the Galaxy S23 Ultra’s wide view and full 100x magnification, where the object resolves into something that looks like a flattened pinwheel reflecting the sun.

No one has produced credible evidence that this is anything extraterrestrial. The most plausible explanations — in rough order of likelihood — are a mylar party balloon deflating at altitude, a radar reflector tethered to a weather balloon, or a stabilized solar filter catching glare. The NORAD and FAA balloon incidents of early 2023 conditioned a lot of viewers to assume anything silver in the sky is an object of interest. It usually isn’t.

How the Galaxy S23 Ultra actually gets to 100x

Samsung’s “100x Space Zoom” is a marketing number stacked on top of real hardware. The underlying camera stack on the Galaxy S23 Ultra is:

• 200MP wide main sensor (f/1.7) — handles 1x to roughly 3x via sensor crop
• 10MP 3x telephoto (f/2.4)
• 10MP 10x periscope telephoto (f/4.9) — the workhorse for long-range shots
• 12MP ultrawide (f/2.2) with a 120-degree field of view

Anything beyond 10x is digital zoom with AI upscaling on top. At 30x the results are usable; at 100x you are effectively looking at a heavily processed, cropped, and AI-interpreted image. That is why the “UFO” has such a clean, almost cartoonish silhouette — the camera’s scene engine is doing a lot of the work the optics cannot.

The moon-zoom controversy, and why it matters here

In 2023, Reddit user u/ibreakphotos demonstrated that the S23 Ultra would inject lunar detail into photos of blurry stand-in images of the moon. Samsung later explained on its community forum that its Scene Optimizer uses a trained model to enhance moon photography — detail is not purely captured, some of it is reconstructed.

For a distant, smooth, high-contrast object like the one in the viral clip, the same processing pipeline applies: the phone sharpens edges, flattens noise, and fills in plausible detail. That does not mean the clip is fake — something is genuinely up there — but it does mean the “sharp” look of the object is partly the phone’s interpretation, not a raw optical capture.

What the S23 Ultra is actually good for at long zoom

Two years after launch, the Galaxy S23 Ultra remains one of the better long-zoom phones you can buy used, especially under $400. It earns its keep for:

• Backyard moon and planet shots — 30x to 50x gives recognizable lunar craters with a steady grip or tripod
• Concert and sports zoom — the 10x periscope holds up well at arena distances
• Wildlife spotting — good for framing birds and deer that a standard phone cannot reach
• Surveillance of distant objects — exactly what happened in this viral clip

Where it struggles: low light beyond 10x, fast-moving subjects at full zoom, and any handheld shot above 30x without bracing the phone against something solid.

How the newer Galaxy Ultras compare

Samsung has iterated twice since the S23 Ultra. If you are shopping in 2026, here is how the Ultra line stacks up on zoom:

Model	Main	Telephoto	Periscope	Max Digital Zoom
Galaxy S23 Ultra	200MP	10MP 3x	10MP 10x	100x
Galaxy S24 Ultra	200MP	10MP 3x	50MP 5x	100x (AI-assisted)
Galaxy S25 Ultra	200MP	10MP 3x	50MP 5x	100x (Galaxy AI ProVisual Engine)

Samsung dropped the dedicated 10x periscope after the S23 Ultra in favor of a higher-resolution 5x with a bigger sensor and more aggressive cropping. At ranges past 30x, the S24 Ultra and S25 Ultra pull slightly ahead of the S23 Ultra in detail thanks to the larger periscope sensor — but the S23 Ultra still wins some comparisons in the 10x-to-20x range where its native periscope reach matters most.

How to reproduce a shot like this on an S23 Ultra

1. Open the native Samsung Camera app (third-party apps lose access to full Space Zoom).
2. Tap the tree icon along the zoom strip to lock 10x optical.
3. Pinch or drag the zoom slider past 10x — the screen will switch to a thumbnail guide to help you keep the subject framed.
4. Brace the phone against a fixed object or mount it on a tripod. Any handheld shake is multiplied at 100x.
5. Tap-to-focus on the object and hold half-pressure; use the physical volume button rather than the on-screen shutter to reduce shake.
6. Shoot a short burst of video rather than stills — the AI processing has more frames to work with, and you can screenshot the sharpest moment.

The takeaway

The viral “UFO” clip is a good example of what the Galaxy S23 Ultra’s camera system does well and what it quietly hides. A mid-range, slow-moving reflective object in good daylight — exactly the situation where Space Zoom looks its best — produces an image sharp enough to launch a conspiracy thread. Context, scale, and the role of Samsung’s image processing rarely make it into the replies. As of 2026, the S23 Ultra is still a capable long-zoom phone, particularly on the used market, but every frame you capture past 30x is a collaboration between the lens, the sensor, and the AI.
