Researchers are quite aware of the composition of stars. However, the universe isn’t only made of stars, so they were curious what lies between these cosmic bodies. A new study revealed that stars are separated by some kind of space grease, some toxic molecules that exist exclusively in an interstellar environment.
What lies between stars?
The composition of stars and star systems is no mystery for scientists, but things don’t look the same everywhere in the universe. It turns out the interstellar space looks a bit different than what surrounds the planets in the solar system.
Traveling in an interstellar environment would be difficult, and researchers found another reason for it. All the stars in a galaxy are separated by a strange space grease that would probably stick to any object or body that passes through it. Also, it doesn’t make too pleasant a view.
According to the researchers, this space grease is extremely dirty and toxic. It exists exclusively in the space between stars, but they were able to recreate the material in the laboratory. This way, they could estimate an approximate quantity for the grease beyond stars. Moreover, the figures could help them understand how much carbon lies in the outer space.
This space grease can teach us how much carbon exists in the universe
This is a remarkable finding, since the exact quantity of carbon in the universe has been a mystery. Previous studies suggested only half of it existed in a pure form, but this space explained what happened to the rest of it. Most probably, carbon mixed with hydrogen to form the grease.
While recreating the space grease in the lab, researchers could also find out there’s a huge quantity of it in the interstellar environment. This means a lot of carbon atoms exist in a greasy form in space. However, these studies revealed carbon in a gaseous form is a lot more common in the universe than the greasy one.
Therefore, researchers showed there’s a lot more space grease than we would have thought. Although it’s not clear yet, they assumed this substance could have helped the creation of our planet. A lot more details were published in the journal Monthly Notices of the Royal Astronomical Society.
