Astronomers at the UA have observed neon, a gas best known for its use in colorful electric signs, in disk-shaped clouds of dust and gas that form around young sun-like stars. It is in such clouds, ...

Astronomers have observed neon in disks of dust and gas swirling around sunlike stars for the first time. University of Arizona astronomers who collaborated in the observations say that neon could ...

Neon isotopes from glassy rocks on the ocean floor may hold the key to understanding how Earth formed 4.5 billion years ago. Depending on how slowly or quickly our early planet assembled from the ...

Artist's impression of planets forming around a young star. New, very precise measurements of krypton isotopes from deep in the Earth show that water, carbon and other volatile materials were ...

It could be argued that one of the most perplexing aspects of our solar system is the fact that not every planet is a nice, solid rock like Earth. Some are literally, almost entirely, made of gas. You ...

When the Galileo probe descended through Jupiter's atmosphere in 1995, it found neon to be one-tenth as abundant as predicted. This unexpected finding has led researchers to propose an explanation: at ...

The Earth formed relatively quickly from the cloud of dust and gas around the Sun, trapping water and gases in the planet's mantle, according to research published Dec. 5 in the journal Nature. Apart ...

"Some of the senior researchers thought that it would never be possible to do this, but with some more rigorous tests for a few months, we confirmed that we have done it." When you purchase through ...

The Earth formed relatively quickly from the cloud of dust and gas around the Sun, trapping water and gases in the planet's mantle, based on neon isotopes from the depths of the Earth and deep space.
