An unknown object that looks like a "golden egg" was discovered during the exploration of the seafloor off Alaska by the scholars of the US National Oceanic and Atmospheric Administration (NOAA), the organization revealed.
"This golden orb, likely an egg casing, struck an imaginative chord for many watching [the live feed of the expedition] yesterday," NOAA said on social networks.
The experts reportedly assumed that it could be an egg casing or the remains of a marine sponge, however, they do not know what could have created a hole in it.
"Something tried to get in... or to get out," one scientist noted during the live feed of the exploration, according to media.
The NOAA brought the object to the shore with help of a remotely operated arm in order to conduct a DNA analysis of it, which will probably give more information, the outlet said.
Given that almost 70% of the deep oceans' life is still considered to be not investigated, the scientists expect it to be an exciting new discovery, the media noted.
Apart from mysterious items, an unknown sound could be detected in the ocean. In 1997, the NOAA identified a high amplitude underwater sound, which was called "the bloop." Of various suggested explanations, including underwater military exercises, whales, giant squids or a totally unknown sea creature, the researchers consider the ice calving as the most probable origin of the noise, media reported.
