RCW 120: A Closer Look into the Stellar Nursery

Known in the wide cosmos as RCW 120, this massive celestial structure is a bubble-like cloud of gas and dust, often referred to as a stellar nursery where stars are born.

The Birthplace of Stars

Situated approximately 4,300 light-years away in the Scorpius constellation, RCW 120 has triggered the inception of new stars. Consisting of dense masses of gas and dust, it provides the perfect environment for their formation. Unlike an earthly nursery, the term “stellar nursery,” in the context of astronomy and astrophysics, refers to vast assemblies of gasses and dust where new stars are continuously birthed, nurtured and eventually, launched into the universe.

The Anatomy of RCW 120

RCW 120 is an emission nebula, a type of large, diffused gaseous region that gives off its own light instead of reflecting the light from nearby stars. Reportedly the nebula has an approximate diameter of 23 light-years and stands out brilliantly against the cosmic backdrop.

The Main Star of RCW 120

Dominating the nebula is a massive star that lies at its core - an O-type star. Having a temperature of over 30,000 Kelvin, it emits ultraviolet radiation powerful enough to illuminate, ionize and subsequently push out the surrounding nebula, creating a shell or a bubble. This massive stellar object, an estimated eight and a half times the mass of the Sun, is the dominant force within RCW 120.

Studying RCW 120 and Stellar Evolution

Beyond the sheer spectacle of RCW 120, this emission nebula is of particular interest to astronomers interested in stellar evolution. The idea that these nebulae can act as incubators for star birth gives scientists incredible insights into the life cycles of stars. Moreover, studying RCW 120 can also offer insights into the process of galaxy evolution.

Astronomical Tools Used

To study the intriguing RCW 120, scientists employ radio and infrared telescopes, which provide rich details about the nebula’s structure. Prominent observatories like the Atacama Pathfinder Experiment (APEX) and the European Space Agency’s Herschel Space Observatory have given astronomers clear views of this stellar nursery.
