Astronomers at Yale University have developed a theory aimed at explaining the unusual properties exhibited by the interstellar space body, “Umumwa”, where they found that it might actually be an iceberg of hydrogen, which might be a 900-foot hydrogen that flies through space, which is rare What is seen in nature.
This solid form of hydrogen seen in space is a new type of object, but more of it will appear in the solar system in the future, the research team says.
Umumwa has now passed Saturn’s orbit, but it will take another 10,000 years before it leaves the solar system to its next interstellar destination.
Lead researcher Daryl Seligman, who now works at the University of Chicago, said the 900-foot body has many unusual properties including rapid brightness contrast.
The team says it accelerated in a similar way to the comet, but it showed no evidence of gas or mounting dust being seen normally from the comet.
“Umumwas behavior can be explained if it consists of hydrogen ice,” Seligman and co-researcher Gregory Laughlin say.
“Hydrogen is the most common element in the universe, but it is rarely present in solid form because this requires very cold temperatures, but the way in which frozen hydrogen interacts with sunlight can provide a convincing mechanism of acceleration,” the researchers added.
They explained, “When Umumwa passed near the sun and got warm, the melting of the hydrogen would have boiled quickly on the ice surface, and this had resulted in” the observed acceleration as well as the dissolution. ”
