What scientific term names the stellar cradles often referred to as nebulae?
Answer
Giant molecular clouds
The initial cosmic regions where stars are formed are scientifically designated as giant molecular clouds. These stellar cradles are enormous structures spanning many light-years. They are crucial because they contain the raw material necessary for star birth, consisting primarily of extremely cold molecular hydrogen ($ ext{H}_2$) and helium, along with trace amounts of dust grains. The cold temperature, often just tens of degrees above absolute zero, is vital as it slows the movement of gas particles, thereby reducing the internal pressure that resists gravitational collapse, allowing gravity to gain the upper hand in forming stars.
