Astronauts on the International Space Station captured mysterious blue orbs in the sky last year. NASA’s Earth Observatory shared the photo last year, but it was taken down shortly after. The photograph was taken as the ISS passed over Southeast Asia. Orbs that appear extraterrestrial in nature aren’t nearly as mysterious as you might think, though.
The Earth Observatory keeps an eye on our planet as the International Space Station makes its rounds, looking for something that will help scientists to know and understand things better. Earlier, the observatory took a photo of a newly born Pacific island. That photo, like this photo of mysterious blue spheres in the sky, could provide new points of information for scientists to look at.
The photograph of the blue spheres in the sky was captured by a member of the Expedition 66 crew and was acquired on October 30, 2021 – almost exactly the year. Photographed using a Nikon D5 digital camera with a focal length of 28 millimeters, NASA’s Earth Observatory noted in a post on its website.
While the photo may have caused some discomfort to anyone looking at it out of context, the mysterious blue spheres are not to be feared. But both spheres have a logical and sound reason behind their existence, NASA says. The first sphere, located near the bottom center of the image, was struck by lightning.
These are usually hidden by clouds. But because the clouds were not very heavy in that region of the world, the astronaut on the ISS was able to capture the blue sphere in the sky that you see in the image above.
The second mysterious sphere that appears on the right edge of the picture is actually the Moon. Our moon is a natural reflector of light – which is why it appears as brightly as it does in the sky every night. However, this night, because of where the photographer was in relation, it appears more like a mysterious blue sphere in the sky, and less like the moon we see every day.
Yet even with these mundane explanations behind the spheres, seeing these bright blue orbs floating in the sky is evocative, and the image itself is very compelling. Hopefully, those aboard the International Station will continue to deliver amazing images like this until NASA launches the ISS sometime in the 2030s.
