Oumuamua May Not be a Hydrogen Iceberg After All as New Study Proves Previous Claims Inaccurate


Just a few months back, it was claimed that the interstellar object Oumuamua is made up of hydrogen ice.


Now, the claims have been proved wrong in another study conducted by the scientists at the Center for Astrophysics, Harvard & Smithsonian (CfA), and the Korea Astronomy and Space Science Institute (KASI).


The new claim is the result of curiosity by these scientists to know how a hydrogen-based object made its way from interstellar space to our solar system.


The debate over the origins and molecular structure of Oumuamua was published on Monday in the Astrophysical Journal Letters , which mentioned that the interstellar object is indeed not made of molecular hydrogen ice.


Dr. Thiem Hoang, the lead author of the latest study, said, “The proposal by Seligman and Laughlin appeared promising, however, their theory is based on an assumption that H2 ice could form in dense molecular clouds.” Hoang is a senior researcher in the theoretical astrophysics group at KASI.


The scientists mentioned that they got suspicious of the claims after realizing that hydrogen icebergs could not survive the journey from space to the solar system, as it takes hundreds of millions of years, resulting in evaporation of icebergs.
