Molecular Cloud Latest News

Recently, astronomers studied the L328 molecular cloud, located around 700 light years away, to map the magnetic fields at multiple scales.

About Molecular Cloud

• It is an interstellar cloud of gas and dust in which molecules can form, the most common of which is hydrogen (H2).

Properties of Molecular Cloud

• These are characterized by their low temperatures (below 40 K, colder than liquid nitrogen) and relatively high densities (103–104 particles per cubic cm).
• Size: The size of these clouds can be from a few light years up to 600 light years. Their total mass can reach several million solar masses.
• Molecular clouds with dimensions of more than about 15 light years are also called giant molecular clouds.
• The complex interplay between three key forces, namely gravity, magnetic fields, and turbulence, determines how these clouds collapse to form stars.
• The central regions of these clouds are completely hidden from view by dust. 
• They are the raw material of stars and planets. These clouds do not last for a very long time.
• After the new stars are born, their solar winds blow away the remaining gas and dust. 

Significance of Molecular Cloud

• Molecular clouds are so important because they are the raw material of stars and planets. 
• It is thought to be the birthplace of stars and planetary systems through processes of contraction, condensation, and accretion.
