The secret lies in the ratio of two specific elements. Scientists have observed something unexpected in Venus' atmosphere — an increase in the level of deuterium relative to hydrogen. Okay, sure ...

Water is made up of hydrogen and oxygen atoms and therefore knowledge of the deuterium abundance in a body of water provides a clue to that body’s history and origin. This is a key component of ...

Water (or the solution of water and deuterium oxide) was allowed ad libitum, and the amount consumed was recorded each day For the studies of metabolic balance animals (control and experimental ...

This isotope of hydrogen is called deuterium, and heavy water's more scientific name is deuterium oxide, abbreviated as D 2 0. With the ...

Water with deuterium sticks to dust grains more readily than regular water does, and when ice clinging to the dust grains is released into the vapor trail of a comet, ...

Water found in the mantle has about 15 percent less deuterium than seawater; that extra seawater deuterium most likely came from somewhere else. Astronomers initially theorized that deuterium-rich ...

A team led by astronomers at Leiden University in the Netherlands and the National Radio Astronomy Observatory in Virginia (U ...
