US astronaut Scott Kelly tweeted a stunning image from the space that attracted lots of attention in social media. The image shows the world from 155 miles but the "thing" in the top right of the image is what fascinated several people particularly UFO spotters.
YouTube channel Sonofmabarker posted a video stating: "Last night aboard the Space Station astronaut Scott Kelly tweeted this photo.
"It was taken while the ISS was over India.
"In the upper right of the photo you can clearly see a large object with two lights on each end.
"It also appears to be very large and constructed.
"I would find it hard to believe that Scott Kelly did not notice this when he tweeted this out.
"It really sticks out like a sore thumb.
"Scott Kelly thank you for sending this photo down to Earth.
"Hardly a week goes by without someone from the ISS sending us a photo or video that really is quite strange and it is left for us to decide."
Meanwhile, Scott C Waring, editor of blog site UFOsightingsdaily.com, said: "When an astronaut tweets a photo of a UFO, you can bet people notice it.
"Scott Kelly likes to send out photos of the view from the windows of the space station, and they look cool.
"This one however has a cigar shaped glowing UFO with a metallic body in it.
"The UFO is about 25 meters long and 150 to 200 meters away.
"It looks like Scott was trying to hint at the existence of aliens. Message received Scott, and thanks."
