- The Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy’s appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye. The term Milky Way is a translation of the Latin via lactea, from the Greek γαλαξίας κύκλος (galaxías kýklos), meaning “milky circle”. From Earth, the Milky Way appears as a band because its disk-shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s, most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Doust Curtis, observations by Edwin Hubble showed that the Milky Way is just one of many galaxies.
- Utopian and dystopian fiction (Wikipedia)
Utopian and dystopian fiction are subgenres of science fiction that explore social and political structures. Utopian fiction portrays a setting that agrees with the author’s ethos, having various attributes of another reality intended to appeal to readers. Dystopian fiction offers the opposite: the portrayal of a setting that completely disagrees with the author’s ethos. Some novels combine both genres, often as a metaphor for the different directions humanity can take depending on its choices, ending up with one of two possible futures. Both utopias and dystopias are commonly found in science fiction and other types of speculative fiction.
