New Information About Interstellar Comet Oumuamua Reached

Work on the interstellar comet Oumuamua, which entered the Solar System last year, continues. Scientists studying about Oumuamua have determined that Oumuamua emits 26 times more carbon monoxide than an average comet.


A very interesting comet entered the Solar System last year. Scientists working on the comet have discovered that the comet Oumuamua, meaning Hawaiian messenger, comes from another star system.


Scientists who want to learn about planetary systems outside the Solar System have been working on the comet since Oumuamua was discovered to come from another system.


Oumuamua has a different structure than the known comets

Scientists who wanted to examine the structure and properties of Oumuamua targeted the Atacama Large Millimeter / submillimeter Array (ALMA) radio telescope to Oumuamua last December.


In observations in the interstellar comet with ALMA, it was discovered that hydrogen cyanide (HCN) and carbon monoxide spread from the comet into space. The amount of carbon monoxide emitted from Oumuamua was discovered to be 26 times the amount of carbon monoxide emitted from an average comet.


Scientists think that a large amount of carbon monoxide emitted from the comet is caused by a large amount of CO ice in the comet . The large amount of CO ice in the comet suggests that Oumuamua comes from an extremely cold system.


"If the gases we observe reflect the composition of the comet's birthplace, the comet may have formed in an extremely cold and outer region of the distant planetary system ," said astrochemist Martin Cordiner, a researcher of the study on Oumuamua .


The researchers say that their work caused more problems about the comet. The data from Oumuamua can be compared with data from new comets that will enter the Solar System from now on.


The study on Oumuamua led to the emergence of new information

about planetary systems outside the Solar System . Planetary scientist Stefanie Milam, one of the Oumuamua researchers, said Oumuamua offers the first look at the chemistry of other planetary systems.
