It seemed unbelievable when NASA showed the smooth, sharp-angled, tabular and flat rectangular iceberg floating in northern Antarctica. While we wonder about how iceberg can be shaped this way, NASA confirmed that the perfectly rectangle iceberg was a result of a natural phenomenon.

NASA uploaded the picture on 17th October, which was taken by the IceBridge flight of NASA a day before on 16th October. But, after its upload on Twitter, many doubts and speculations were raised about the authenticity of the photograph and many wondered if the photo of was real. The corners of the rectangular iceberg were so perfectly curved at right angle that even the NASA team believed that the photographed region may not be natural. However, NASA soon confirmed that the mysterious rectangular iceberg is natural and real.

Many icebergs were found in relatively straight edges, but this iceberg is like never seen before, and it is the very first iceberg found with this unique shape, which seems to be formed by any humans, but it is not. “I thought it was pretty interesting; I often see icebergs with relatively straight edges, but I’ve not really seen one before with two corners at such right angles like this one had,” said the senior support scientist of the IceBridge flight at NASA.

In reply to this tweet, a lot of people claimed that it was caused by the aliens, some said it was man-made, and some said that is natural. Given that the shape of the found iceberg is very rare but research about how is it formed must be in progress by now. So for now, we believe that this shape is formed naturally, as NASA says it must have formed naturally.
