When it comes to baby blankets, the fluffier, the better — and astronomers have discovered that some infant stars in the early universe also preferred "fluffy" pre-natal cocoons.
Stars are born in "stellar nurseries," or regions of galaxies with an abundance of gas and dust that can become overly dense and collapse to form infant stars, or "protostars." More accurately referred to as "molecular clouds," these gaseous conglomerations can stretch for hundreds of light-years, thus forming thousands of stars.
