The phylogenetic diversification and ecological radiation of angiosperms (flowering plants) in the Early Cretaceous, between about 135 and 65 million years ago, was one of the major biotic upheavals in the early stages of the history of life. It had dramatic consequences for the composition and subsequent evolution of terrestrial ecosystems. Ancient Mesozoic vegetation, dominated […]

Introduction:  The displacement of an astronomical object’s spectrum toward longer (red) wavelengths is known as redshift. The Doppler effect, a shift in wavelength that occurs when a source of waves (e.gLight or radio waves) and an observer are moving in relation to one another is the basis of this theory. In 1929, American astronomer Edwin

Planets are often named after mythological gods and goddesses. For example, the planet Mercury is named after the Roman god of commerce and communication. Most planets are much larger than Earth.
