How was Oumuamua made?
This research, published in the pre-print journal Arxiv, states that this object was born from a giant molecular cloud (GMC). This is where molecules like hydrogen are made. In most other places there is only ionized gas. Hydrogen is found in the largest amount in the universe but hydrogen ice is the rarest. It gets such temperature only in places like GMC.
In the study, scientists have said that if such a physical association is possible, then we expect that the path of Oumuamua will pass through it. It doesn’t matter if it’s a comet-like object ejected from a protoplanetary disk or formed from a GMC itself.
What is the reason behind the high speed?
Experts have described Carina-Near and Columba- these two associations as the GMC from which it may have originated. He says that Oumuamua’s motion is in sync with the other members of Carina. Both GMCs are 10-16 million light years away from Earth in deep space. Based on its shape, it is also indicated to be made of frozen hydrogen. It looked like a cigar. He also says that due to the hydrogen ice, only a small amount would be needed for it to grow at such a fast rate. Earlier, Yale’s research itself had found that hydrogen ice was present in it.
Sample alien technology?
Earlier, Harvard University professor Avi Loeb had claimed that the space rock Oumuamua seen on October 19, 2017 was actually evidence of alien life. It was seen by the University of Hawaii’s PAN-STARRS1 telescope. This cigar-shaped object passed close to Earth at a speed of 1.96 lakh miles per hour and was considered a comet or asteroid. The biggest claim that Avi makes as evidence of its alien life is the effect of the Sun’s gravity. He told that the speed of space objects becomes faster when they go closer to the sun and slower when they go away. However, this was not happening with Oumuamua.
