Scientists discovered that methyl halides, a gas produced by microbes, could be a biosignature for life on distant planets.

The formula H₂O shows that water is made from two atoms of hydrogen (H) bonded to one atom of oxygen (O). Katie: Time for some science. And today it's a chemistry classic, the periodic table.

As the supernovae expand and cool, oxygen from the ejecta reacts with H and H 2 to form water in the halo, and H 2 also forms on dust grains,” study authors explained in a ne ...

Hydrogen is a much-debated option in terms of CO₂-neutral energy production. Electrolyzer units that split water into its ...

The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. When two hydrogen atoms and an oxygen atom get close ...

Snow is made up of trillions of tiny ice crystals to make snowflakes, with not one alike. Here's how they form.

Much of Earth’s hydrogen escaped into space early on, but some remained bonded with oxygen to form water, essential for life.

Researchers from Johannes Gutenberg University Mainz have developed water-splitting catalysts that are both cost-effective ...
