This nebula began to form about 200 years ago, and primarily consists of molecular gas.

However, these do not remove certain industrial pollutants, such as volatile oils, and excess simple molecular gases.

This is what we see in today's elliptical galaxies, very little molecular gas and very few young stars.

Additional observations are needed to confirm that the Sombrero galaxy's molecular gas is constrained to the ring.

Starburst galaxies feature a large amount of cool molecular gas in a small volume.

Dr. Brown said the quantity of the molecular gas was astonishing.

"I can't think of another object in the universe that has anything like that mass of molecular gas," he said.

Not that you haven't turned thousands of people into so much molecular gas.

In both cases, bipolar outflows consist largely of molecular gas.

Stars form in clumps of cool molecular gas that hide the nascent stars.
