Astronomers have mapped 39 interstellar clouds where high-mass stars are expected to form. This large data set shows that the accepted model of low-mass star formation needs to be expanded to explain the formation of high-mass ...

Clouds in the southern hemisphere reflect more sunlight than those in the northern hemisphere. The reason is a more frequent occurrence of liquid water droplets, which results from an interplay between updrafts and a cleaner ...

High within towering thunderclouds, a distinct form of intracloud lightning, known as "narrow bipolar pulse" discharges, can occur. Like other forms of lightning, narrow bipolar events (NBE) can be either negative or positive ...

Stars are formed by molecular gas and dust coalescing in space. These molecular gases are so dilute and cold that they are invisible to the human eye, but they do emit faint radio waves that can be observed by radio telescopes.

The re-distribution of anthropogenic aerosol emissions from Europe and North America towards China and India between 1996 and 2010 has surprisingly warmed rather than cooled the global climate. This result reinforces the ...
