The celestial body ‘Oumuamua, which was discovered in our solar system in 2017, is still a mystery.
Two researchers propose a new thesis
Alan Jackson and Steven Desch from Arizona State University in the USA have now found a new explanation: ‘Oumuamua is probably a fragment of an exoplanet that could have been formed in a collision with an asteroid. The researchers represent this thesis in two studies that they published in the journal “Journal of Geophysical Research: Planets”, writes the “Spiegel”.
“If the conclusions are correct, that would be an important milestone in astronomy,” writes Spiegel Online. The researchers then observed a fragment of an exoplanet for the first time in 2017.
By the way, Jackson and Desch now assume that ‘Oumuamua comes from an exo-Pluto. The collision took place about half a billion years ago and released the cigar-shaped splinter into space. ‘Oumuamua is said to be made of frozen nitrogen that has already melted on the outside.
