So, it’s not all that surprising that I’ve spent most of my life looking at clouds. All clouds form as a result of saturation – that’s when the air contains so much water vapor that it begins ...

High concentrations of gas and dust coalesce to form a baby star in regions of space known as stellar nurseries, Also called molecular clouds, they can be massive, spanning hundreds of light-years and ...

“The data indicates that the youngest stars form in filaments of gas,” Loeb said. “Subsequently the gas cools and fragments into later generations of stars in less filamentary structures. This ...

Some believe that it could be due to less air pollution: When particulates are in the air, it can make it easier for water droplets to stick to them and form clouds. Another possibility ...

Martian clouds are sometimes made of water-based ice, but because the atmosphere is over 95 percent carbon dioxide, CO2 ice can also form at both higher and lower altitudes. These latter clouds are ...

All clouds form as a result of saturation – that’s when the air contains so much water vapor that it begins producing liquid or ice. Once you understand how certain clouds develop their shapes ...
