'UFO' Sighting From Space Station Explained: What Is It Really?

Not long after that California UFO sighting, which turned out to be a missile, another such report emerged after astronaut Scott Kelly shared a photo of India from his vantage point in outer space.

"It was a pretty typical day aboard the International Space Station (ISS) on Nov. 15, what with experiments to run, equipment to maintain," Time said, "when astronaut Scott Kelly, who is two-thirds of the way through his marathon one year in space, sent out this tweet:"

"Day 233. Once upon a #star over Southern India. #GoodNight from @space_station! #YearInSpace."

Although Kelly didn't notice anything odd in his space snap, UFO Sightings Daily's Scott C. Waring did, specifically on the image's upper right hand portion.

"The UFO is about 25 meters long asnd 150 to 200 meters away," he noted, adding that it appeared to be cigar-shaped and had a metallic body.

However, other more skeptical observers had other theories for the sighting, with some saying it's just the reflection of the space station's window. Or that it's a portion of the ISS that just caught some light and appeared like a mysterious flying object in the image.

"It probably isn't clear, but the little grey cylinder that kind of looks like an unlabeled tuna can is the HDEV*, or High-Definition Earth Viewing system, installed aboard the ESA's Columbus module," Forbes pointed out, adding that the HDEV is very reflective. As such, it's likely to shine light back when the ISS is lit up.

Later, ISS engineer Sam Treadgold contacted the business and finance news source to clarify the thing that was identified as a UFO.

"Thanks for pointing out that the picture was actually of a piece of station hardware, however you have misidentified the particular hardware," Treadgold explained. "It is not HDEV. HDEV is the box-like camera on the Columbus external payload facility."

"The hardware in the notable image is in fact the UHF antenna on the Destiny Lab," he concluded.

So there you have it, the answer to the puzzle that sparked yet another round of UFO rumors. This is not the first time that astronaut activity involved UFO speculations, though.

There's that instance in 1962 when John Glenn called ice crystals that broke away from his ship as "fireflies." Then there's another one in 1965 after Frank Borman called a booster a "bogey," which was actually how pilots call enemy aircraft. However, members of the media appeared to understand it to refer to UFOs.
