Mysterious interstellar ‘Oumuamua can be made from something almost unheard of in science

The mystery surrounding interstellar objects ‘Oumumua seems to be getting weirder from day to day.

A new study, which has not been reviewed by colleagues, shows that interstellar objects can be made from hydrogen ice. Hydrogen is the most abundant element in the universe, but is rarely observed in solid form.

“We developed a theory that explains all the strange nature of Oumuamua,” said study co-author Gregory Laughlin, a professor of astronomy at Yale’s School of Arts and Sciences, in a statement. “We show that it may consist of hydrogen ice. This is a new type of object, but it seems like more of them are appearing, moving forward.”

Oumuamua is in the form of a cigar, which was first discovered in October 2017, unlike anything researchers have seen before, due to its shape, and dry surface.

The research notes that hydrogen ice, which requires extremely cold temperatures, is something that is in the nucleus of molecular clouds. Molecular clouds form the basis of stars and researchers believe umu Oumuamua can contain hydrogen ice after passing through one of these molecular clouds in space, which can explain its speed.

“When ‘Oumuamua passes close to the Sun and receives its warmth, melted hydrogen will quickly boil from the surface of the ice,” the study’s lead author, Darryl Seligman explains, “provides the observed acceleration and also winnows’ Oumuamua to strange, elongated shapes – like a bar. soap becomes a thin slice after much use in the bathroom. “

It is possible that this “hydrogen iceberg” or “hydrogen comet” could be more prevalent in the solar system, which could give researchers new information about how stars and planets form.

“Their presence will be an accurate investigation of conditions in the dark recesses of star-forming clouds and provide critical new clues to understanding the initial phase of the still mysterious process that results in the birth of stars and accompanying planets,” Laughlin noted.

Oumuamua’s cigar-shaped 900 feet long has led some researchers to believe that it could be an alien investigation.

A study was published in November 2018 the Harvard Smithsonian Center for Astrophysics suggested that it could be “artificial light” sent from other civilizations.

The researcher who discovered ‘Oumuamua, Canadian physicist and astronomer Robert Weryk, said the idea that of other civilizations is simply “wild speculation.”

No longer seen by telescopes in January 2018, many have speculated about ‘Ouamumua. In addition to with the light sailing theory, some have theorized that that a comet or an asteroid.

The mystery about its exact nature deepened at the end of 2018, when NASA said it had been looking in the direction of ‘Ouamumua for two months but at first didn’t see it.
