New uses for abandoned molecule calcium carbide

A joint project of scientists from Russia has investigated chemical applications of calcium carbide. The project advances the idea of diverse acetylene chemistry on the basis of carbide technology. Using the proposed approach, ...

The discovery of the molecule Si-C-Si in space

The space between stars is not empty—it contains a vast reservoir of diffuse material with about 5-10% of the total mass of our Milky Way galaxy. Most of the material is gas, but about 1% of this mass (quite a lot in astronomical ...

New 'molecular movie' reveals ultrafast chemistry in motion

Scientists for the first time tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry and ...

Water could have been abundant in the first billion years

How soon after the Big Bang could water have existed? Not right away, because water molecules contain oxygen and oxygen had to be formed in the first stars. Then that oxygen had to disperse and unite with hydrogen in significant ...

Moist explanation for Saturn's Great White Spots

Once every 20 or 30 years, a superstorm greater than Earth breaks out on Saturn and whips around the ringed planet in a violent spectacle that rages for months on end.

Why does the Milky Way rotate?

We live in a galaxy that is called the Milky Way. It's called a barred spiral galaxy, which means that it has a spiral shape with a bar of stars across its middle. The galaxy is rather huge—at least 100,000 light-years ...
