Despite great hardship caused by limited power, loss of cabin heat, shortage of potable water, and the critical need to jury-rig the carbon dioxide removal system, the crew returned safely to Earth on April 17.
Streetcap1 found in NASA's archive an amazing image of an unknown object close to the Apollo 13. See the video below.
Further he said "If you save the image to your computer you need to increase the brightness to see the object."
So, I saved image 8528, Streetcap1 is talking about, and I also saved the next image nr. 8529 and brightness both images with 'auto adjust colors' and this is how it looks.

We see some unnatural objects and it looks like they are positioned around the Apollo 13 module. According to Scott Waring there is a possibility that these objects are alien craft, observing the module in case they needed to offer assistance.

But if we are looking at the following image, we see a solid object at the front of a bright object approaching the module and I'm wondering if this unidentified flying object is the real cause of all the malfunctions in the Apollo 13 module.
Images taken before and after the numbers 8528 and 8529 also show some strange UFO-like objects.
