Omega Centauri probably has no sign of life, scientists say



Omega Centauri has been expelled to have a possible habitable zone. According to the researchers, the speed at which their stars interact with each other would be too high to accommodate any form of life.

Humans may need to do more space exploration to look for extraterrestrial life because researchers have discovered that Omega Centauri has none.

Omega Centauri is a dense, packed global star cluster estimated to have around 10 million stars. The star cluster is located 16,000 light-years from Earth in the constellation Centaurus.

Due to the colossal size of the cluster, it has been observed for decades. The stars cover an incredible 150 light-years and weigh about 4 million suns.

Because of how great that is, many people have convinced that the stellar body contains exoplanets in its "Goldilocks Zone." Another world is far enough away from its star to have liquid water and life, as well the earth.

Like Stephen Kane, an Associate Professor of Planetary Astrophysics at the University of California, Riverside and lead author of the study, as the kind of star cluster that exists throughout the universe, it's a fascinating area to search for habitability. Despite many stars concentrating on their core, the existence of exoplanets is still unknown.

For this reason, Kane and his colleagues explored the cluster, hoping to find a place that promotes livability. The team first studied the age and temperature of about 500,000 stars sitting in the core of the Brocken.

The results

The study found that the majority of the body has suitable conditions for the uptake of planets in the habitable zone. Kane said that the core of Omega Centauri could possibly have a plethora of planetary systems sitting close to a host star housing habitable planets.

An example of such a system is a miniature version of the Milky Way called TRAPPIST-1. The system is located 40 light-years from Earth and is one of the most promising places to find a foreign life.

The densely packed stars in Omega Centauri's core probably mean that the bodies would interact with their neighbors. The forces that come from the encounter would be too much to endure any kind of microbial life on the planet in their habitable zones.

Sarah Deveny, the co-author of the study, said that the frequency of star gravitational interaction would be too high to obtain stable planets that are suitable for residents.

The average distance at the cluster core of the star is only 0.16 light-years, making it scarce once in a million years. This rate is much faster than the sun, which is 4.22 light-years from its nearest neighbor.

The study titled "Habitability in the Omega Centauri Cluster" is published in . The Astrophysical Journal and arXiv Paper
