A self-proclaimed alien hunter was quick to ask questions when a strange object appeared above the Earth on a livestream from the International Space Station.
"I've been watching it [the live feed] for years but never seen any UFOs on it before," UK resident John Craddick told UK paper The Mirror.
"I was showing a friend how it worked at around 11:30pm when the feed cut out, and 35 seconds after it came back on, this object appeared.
"At first it was really small and then it grew bigger, lasting for about 25 seconds."
Mr Craddick claimed it must be alien because "nothing human can fly that high".
It follows a similar sighting in November, where a white speck could be seen in the distance for about five seconds before the feed cut out. Similar incidents occurred in July and October last year.
NASA in the past has dismissed the conspiracy theories.
"Reflections from station windows, the spacecraft structure itself or lights from Earth commonly appear as artefacts in photos and videos from the orbiting laboratory," a spokesperson said last year.
The International Space Station orbits the Earth 16 times a day, and it isn't uncommon for it to slip out satellite range, resulting in the live feed being temporarily cut off.
Meteors are also burning up in the outer atmosphere all the time, as well as human-made space debris.
"No unidentifiable objects have been seen from the International Space Station," NASA said.
