Scientists are rethinking how to detect alien life by focusing on planets vastly different from Earth. Instead of searching ...

Scientists have identified a promising new way to detect life on faraway planets, hinging on worlds that look nothing like ...

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

Large reserves of white hydrogen may exist within mountain ranges, according to a new study, raising hopes this clean-burning gas can be extracted and supercharge efforts to tackle the climate crisis.

They react with metals to form metal halides, and with hydrogen to form acidic hydrogen halides. Reactivity decreases down the group. Group 0 - the noble gases - Edexcel The group 0 elements ...

Called methyl halides, the gases comprise a methyl group, which bears a carbon and three hydrogen atoms, attached to a halogen atom such as chlorine or bromine. They’re primarily produced on ...
