Distances of the nearest stars from 20,000 years ago until 80,000 years in the future Visualisation of the orbit of the Sun (yellow dot and white curve) around the Galactic Centre (GC) in the last galactic year. The red dots correspond to the positions of the stars studied by the European Southern Observatory in a monitoring programme. [71]
GfK predicts a 200% increase in Ultra HD screen sales from June to December 2015, with sales expected to reach five million by the end of the year. GfK also forecasts that Ultra HD screens in 2020 will represent more than 70% of total sales across Europe and almost 60% in the Middle East and North Africa. [177]

The Sun emits light across the visible spectrum, so its color is white, with a CIE color-space index near (0.3, 0.3), when viewed from space or when the Sun is high in the sky. The Solar radiance per wavelength peaks in the green portion of the spectrum when viewed from space.
where dn=1 on January 1; dn=32 on February 1; dn=59 on March 1 (except on leap years, where dn=60), etc. In this formula dn–3 is used, because in modern times Earth's perihelion, the closest approach to the Sun and, therefore, the maximum E ext occurs around January 3 each year. The value of 0.033412 is determined knowing that the ratio ...
