Artist's conception of Epsilon Eridani
Artist's conception

Epsilon Eridani is a star in the constellation of Eridanus. Viewable from most of Earth's surface along a declination 9.46° south of the celestial equator, it is 10.5 light-years away and has an apparent magnitude of 3.73. It is the third-closest individual star or star system visible to the unaided eye. Estimated at less than a billion years old, the young star has a higher level of magnetic activity than the present-day Sun, with a stellar wind 30 times as strong. Epsilon Eridani is smaller and less massive than the Sun, with a greater proportion of hydrogen and helium. It is a main-sequence star of spectral class K2, which means that energy generated at the core through nuclear fusion of hydrogen is emitted from the surface at a temperature of about 5,000 K, giving it an orange hue. Observations for more than twenty years have yielded evidence of a giant planet orbiting the star, making it one of the nearest systems with a candidate exoplanet. The detection of this planet, Epsilon Eridani b, was announced by Bruce Campbell, Gordon Walker and Stephenson Yang in 1987. (Full article...)

Saudade

Saudade, an oil on canvas painting completed in 1899 by José Ferraz de Almeida Júnior. The Portuguese word saudade refers to a deep emotional state of nostalgic or profound melancholic longing for a beloved, and often connotes a repressed knowledge that the object of longing might never return. Once described as "the love that remains" after someone is gone, saudade now refers to a sense that someone or something that should be present is missing.

Painting: José Ferraz de Almeida Júnior
