In the COSMOS-AzTEC-1 galaxy, stars are born inexplicably often

(ORDO NEWS) — The COSMOS-AzTEC-1 galaxy is known among astronomers as an “anomalous monster” and the reason for this is the incredibly frequent and rapid star formation. The galaxy, formed more than 13 billion years ago, is filled with unstable clouds of gas that continue to stamp out stars.

It is striking that stars in COSMOS-AzTEC-1 are born everywhere, but given the age of the galaxy, active star formation should be observed only in the central part. For some reason, gas clouds are everywhere and stars are born one after another.

“This monster is demonstrating something inexplicable. Observational results indicate that stars in COSMOS-AzTEC-1 are born 1000 times more often than in the Milky Way. Probably, relatively recently, the galaxy has swallowed several others,” explained the study’s author Ken-Ichi Tadaki.

Astronomers are convinced that the COSMOS-AzTEC-1 galaxy could not have accumulated such huge reserves of gas immediately after birth. Perhaps this “monster” throughout its history was engaged in “devouring” other, smaller and younger galaxies.

Cosmological models describe active star formation at an early stage of development, but after that the galaxy “slows down” and becomes passive, like the Milky Way. COSMOS-AzTEC-1 lives by its own rules and has been tirelessly forming stars for several billion years, filling space with light.
