(ORDO NEWS) — 8292 stellar streams have recently been discovered in the Milky Way. They were named Theia.
The Theia 456 flow turned out to be special. Scientists have found that all 468 of this association were born at the same time. This is evidenced by the same iron content in stars that appeared about 100 million years ago. Now they are moving in the same direction across the sky, writes Phys.org.
Most star clusters form together, according to Northwestern University astrophysicist Jeff Andrews.
“But what is exciting about Teia 456 is that it is not a small group of stars. It is long and extended,” he explained.
It is noted that Theia 456 stretches for more than 500 light years, is located in the galactic plane of the Milky Way.
Recall that stellar streams are associations of stars with a linear structure. They revolve around the centers of galaxies and were themselves once dwarf galaxies or globular clusters.
Previously, scientists discovered a roving Earth clone in space. The planet was named OGLE-2016-BLG-1928. It drifts in the Milky Way. According to astronomers, the conditions for “wandering” are created by the gravitational weakening of the Sun. As a result, large objects can freely move in space without being tied to any specific star systems.
