The diagram has three main features: the red sequence, the green valley, and the blue cloud. The red sequence includes most red galaxies, which are generally elliptical galaxies. The blue cloud includes most blue galaxies, which are generally spirals. In between the two distributions is an underpopulated space known as the green valley which ...
Column hanging from the cloud base which can develop into a small funnel cloud. [13] Accessory clouds Pannus Accompanied by a lower layer of fractus species cloud forming in precipitation. Pileus Small cap-like cloud over parent cumulus cloud. Velum A thin horizontal sheet that forms around the middle of a cumulus cloud. [13] Mother clouds
It glows with the characteristic red of an H II region. [1] An interstellar cloud is generally an accumulation of gas, plasma, and dust in our and other galaxies. But differently, an interstellar cloud is a denser-than-average region of the interstellar medium, the matter and radiation that exists in the space between the star systems in a
The blue sky spectrum contains light at all visible wavelengths with a broad maximum around 450–485 nm, the wavelengths of the color blue. Diffuse sky radiation is solar radiation reaching the Earth 's surface after having been scattered from the direct solar beam by molecules or particulates in the atmosphere .
We also see the Rayleigh effect at play in: -Sunsets where the sky is red.Light has to pass through a larger part of the atmosphere when the sun is lower on the horizon. Red, orange and yellow ...
Instead of large gas clouds collapsing to form a galaxy in which the gas breaks up into smaller clouds, it is proposed that matter started out in these “smaller” clumps (mass on the order of globular clusters), and then many of these clumps merged to form galaxies, [3] which then were drawn by gravitation to form galaxy clusters. This still ...
