The bubbles contain rare types of hydrogen and nitrogen that are not found on Earth. They were formed in intense cold, -260 C.  The discovery of the organic globules, he said, helps scientists understand more about how a cold, molecular cloud collapses to form a solar system like ours. The bulk of the meteorite is believed to be roughly 4.5 billion years old. The globules could be even more ancient, material that was incorporated into the rock when it formed.
