Gas giant composition not determined by host star

A surprising analysis of the composition of gas giant exoplanets and their host stars shows that there isn't a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium, according ...

No assumptions needed to simulate petroleum reservoirs

Hidden deep below our feet, petroleum reservoirs are made up of hydrocarbons like oil and natural gas, stored within porous rock. These systems are particularly interesting to physicists, as they clearly show how temperature ...

Stars memorize rebirth of our home galaxy

The Milky Way galaxy has died once before, and we are now in what is considered its second life. Calculations by Masafumi Noguchi (Tohoku University) have revealed previously unknown details about the Milky Way. These were ...

A laser that tracks like a hound

University of Adelaide researchers have created a laser that can "smell" different gases within a sample.

Forest of molecular signals observed in star-forming galaxy

Ryo Ando, a graduate student of the University of Tokyo, and his colleagues have observed the galaxy NGC 253 and resolved its locations of star formation down to the scale of a molecular cloud, a star formation site with ...

Westerly winds and CO2 levels

The end of the last Ice Age was preceded by a gradual rise in atmospheric CO2. A new study supports the idea that a shift in the position, and increase in the intensity, of zonal westerly winds in the Southern hemisphere ...
