Stargazing
From Tardis Wiki, the free Doctor Who reference
Stargazing was the hobby of looking at stars, sometimes with a telescope.
Harvey was a keen stargazer, and in the early hours of 12 July, 1979, stayed up to watch Skylab re-enter Earth's atmosphere through his telescope. (PROSE: Bennelong Point)
In 2070, the Tenth Doctor stargazed with Danielle on Centauri-Beta. Due to the composition of the planet's atmosphere, constellations of stars were visible during the day. (PROSE: Total Eclipse of the Heart)
Nyssa and Tegan Jovanka stargazed whilst on Callanna, something that Tegan thought was very uncharacteristic of herself. (AUDIO: Madquake)
