False-color image of the Sun from the STEREO Ahead spacecraft on December 4th, 2006. The image is a composite of four views, each highlighting different temperature regimes in the Sun's upper atmosphere: red (60-80,000 Kelvin), blue (1 million Kelvin), green (1.5 million Kelvin), and yellow (2 million Kelvin). This marks the beginning of the STEREO mission's imaging and its exploration of the Sun in three dimensions.

Is #ASML Holding NV (NASDAQ: ASML) the most important #IT company on earth?

Only they make #extremeultraviolet (#EUV) & #deepultraviolet (#DUV) lithography printers that even #TaiwanSemiconductorManufacturing (NASDAQ:TSM) relies upon.

Their singular machine prints 10M transistors/cm²

$1062/share
ASML allegedly offered to spy on China for the US — company proposed being 'Washington’s eyes and ears in China' after breaking gentlemen’s agreement on limiting DUV sales to country, says new book
ASML is reportedly willing to spy on its customers to make it right with the U.S.

A stunning image from the STEREO (Ahead) spacecraft captures a massive solar prominence erupting from the Sun on September 29. The prominence, composed of hot plasma suspended in twisted magnetic fields, is many times larger than Earth and is shown in extreme ultraviolet light emitted by ionized Helium. This view shows the prominence brightly against the blackness of space.
