A mysterious object spotted during SpaceX's historic Starship flight sent viewers scrambling for explanations after it appeared to glide across the company's livestream, prompting one astonished reaction: 'We just saw an alien mothership.'
The sighting came as Starship Flight 14 lifted off from SpaceX's Starbase facility in South Texas on 28 September. The mission was already historic: Starship reached orbit for the first time and deployed 26 next-generation Starlink V3 satellites, marking a major step beyond the suborbital test flights that preceded it.

Yet an unusual shape visible during the broadcast quickly became a separate talking point online. Some viewers described it as a UFO or even an extraterrestrial spacecraft, according to the report that highlighted the footage.
There is, however, no verified evidence that the object was alien technology, and online viewers have offered far more conventional explanations, including exhaust or material associated with the rocket's staging sequence.
Mysterious Object Appears During Starship Livestream
The strange sighting occurred during a flight watched closely because SpaceX was attempting something Starship had never previously achieved: reaching orbit. Footage circulating online appeared to show an unusual light-coloured formation against the darkness of space.
Its appearance was enough to trigger immediate speculation among some viewers, with the 'alien mothership' remark becoming one of the more dramatic reactions associated with the clip.
Some online viewers who examined the sequence suggested that the shape could have been related to the rocket's exhaust or staging, although that explanation has not been independently confirmed.
No credible source reviewed for this article established that the object was anything other than an unidentified phenomenon visible during the broadcast. There is also no verified evidence connecting it to extraterrestrial technology or life.
Historic Flight Gives Viral Moment Added Attention
The timing helps explain why the footage attracted attention. Flight 14 was not an ordinary Starship test.
Starship lifted off at approximately 7.48am local time from Starbase before reaching orbit for the first time. SpaceX had previously flown 13 Starship missions on suborbital trajectories, making Flight 14 a major milestone in the company's development programme.
The US Federal Aviation Administration authorised the launch and re-entry operations on 26 September. The mission involved the Starship upper stage and Super Heavy booster, with both planned to splash down rather than be recovered at the launch site.
Flight 14 also carried an operational payload. SpaceX sent 26 Starlink V3 satellites towards low-Earth orbit, representing the first Starship flight to deploy an operational payload into orbit.
The flight was not entirely trouble-free. Reports said a Raptor engine shut down unexpectedly during ascent, but mission controllers continued with the planned orbital insertion.
The mission proceeded, and the Starlink payload was subsequently deployed, but the planned flight was shortened from about 10 hours to roughly three hours following the engine shutdown.
What Was the Alleged 'UFO'?
For now, the most accurate answer is that the object visible in the footage has not been independently identified from the available imagery. There is no verified evidence connecting it to extraterrestrial life.
Some viewers suggested that the footage could show rocket exhaust or another phenomenon related to the launch, although that interpretation has not been independently confirmed. Rocket launches can produce visually unusual phenomena as exhaust gases expand rapidly in the extremely thin upper atmosphere and in space.
Camera angles, changing illumination and the relative movement of the spacecraft can make those effects appear particularly striking. That distinction matters because the viral 'alien mothership' reaction risks overshadowing what SpaceX demonstrably achieved.
Whatever the object shown in the footage turns out to have been, Flight 14 itself marked a significant milestone: Starship reached orbit for the first time and deployed operational Starlink satellites.
The flight marked another step in SpaceX's development of the reusable launch system it intends to use for large-scale satellite deployment and missions beyond Earth.
