Shown here is an example visualization from Vanderbilt's Filtergraph tool applied to Hipparcos spacecraft data. Depicted is a so-called Hertzsprung-Russel diagram showing the relationships between stellar temperatures, luminosities, and sizes, and…

With the observations in this manuscript, Tycho Brahe refuted the Aristotelian belief in an unchanging celestial realm. His precise measurements indicated that "new stars," stellae novae, were not tailless comets in the atmosphere as previously…

This is a facsimile of the copy of Sidereus Nuncius by Galileo, originally written in 1610. In it, Galileo published his discovery of four "Medicean Stars" (now known as the Galilean Moons of Jupiter). It also has Galileo's drawings of the moon,…
