Recent studies have significantly expanded our understanding of water on the Moon, revealing that it is not just confined to ...

The researchers used data from the Moon Mineralogy Mapper (M3) instrument on the Chandrayaan-1 spacecraft, which orbited the ...

Flybys of primordial black holes may occur once a decade. Tweaks to the orbits of planets and GPS satellites could give away their presence.

A new study suggests that a microscopic black hole might pass through our solar system once every decade or so.

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen ...

Two principal theories prevail for where all the water went: it either retreated into the ground or sublimed away into space.

Scientists explore Mars water loss, tracing hydrogen and deuterium escape with advanced space telescopes like MAVEN and ...

Like dietary carbohydrates and fats, proteins differ in their quality, and individuals vary in their needs. Determining ...

Most atoms are made from positively charged protons, neutral neutrons and negatively charged electrons. Positronium is an ...

He based his calculations on the hydrogen atom, and more specifically, on the time it takes for the spin of a hydrogen atom’s electron to change relative to its proton. It’s known as the ...

Hydrogen energy, with its green, low-carbon and high-calorific-value properties, is emerging as the new key to solving the ...

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...
