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 ...

Cloud Composition Clouds are a fascinating part of our sky, made up of countless tiny water droplets or ice crystals. When ...

“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 ...

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 ...

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 ...
